While it’s widely known that solar power can dramatically cut your long-term electricity costs, the initial investment in a home solar panel system can be a major barrier for Australians.  

A high-quality residential system, such as a 6.6kW setup, can easily exceed $6,000, and for most households, that’s not spare change. 

However, luckily, in Australia, there’s a smart way to bridge this financial gap. That’s by choosing solar financing options! 

Unlike traditional forms of debt, solar financing can actually pay for itself over time, making the installation process easy and affordable for all groups of people.  

Moreover, by structuring the system properly, a well-sized and efficient solar system can generate significant savings on your energy bill. But not all financing options are created equal.  

The difference between a solar system that boosts your savings and one that drains your wallet often comes down to the financing terms you choose. 

Therefore, at Cyanergy, we’re here to walk you through 5 of the most effective ways to finance your solar panels in Australia. This will help you take control of your energy future, without creating any financial stress.

How Much Does a Fully Installed Solar System Cost in Australia?

In Australia, the cost of a fully installed residential solar system in 2025 generally ranges between $3,500 and $10,000, depending on system size, component quality, and your geographical location. 

However, on average, the cost is $10,000, and people paid from $7,000 to $20,000 for their 10 kW systems 

So, what causes the price differentiation of solar panels? 

  1. The quality of panels and inverter brands, such as SunPower, Q Cells, or Fronius, may come at a higher cost.
  2. Installer rates and reputation matter for cost variation.
  3. Location is a factor, as urban areas often get more competitive quotes than regional or remote areas.
  4. The type of roof and its installation complexity may increase the cost.
  5. Optional battery storage adds $7,000–$15,000, depending on capacity. 

5 Common Methods For Solar Financing for Australians in 2025

Common Methods For Solar Financing

Solar panel financing helps homeowners get the benefits of solar without paying the full cost up front. Instead, you pay in installments through loans, leases, or other payment plans, making solar more affordable over time. 

Don’t worry! It’s not just another debt; it’s a smart way to take control of your energy bills because a well-financed solar system can save you more money than the amount you spend on the investment.  

So, when you want lower power bills and enjoy more energy independence, going solar makes sense.  

But as soon as you start looking into the numbers, it can feel overwhelming. A quality solar system isn’t cheap. And for many Aussie families, it’s a big financial decision.  

Then come all the financial terms, such as zero-interest, buy now, pay later (BNPL), green loans, and solar leasing, which also leave residents even more perplexed. 

Find them confusing, too?  

So, let’s break down 5 ways to finance your solar panels in Australia to help you make the smartest, stress-free decision for your home and your wallet. 

1. Cash Payment

Investing in a solar power system can be highly profitable if you are debt-free and have available cash. Solar systems offer tax-free returns that surpass the current interest rates offered by banks or the government.   

For those who consume a significant amount of electricity during the day, a 6.6kW system costs $6,500. Typically, it recoups its cost within approximately five years, resulting in a 12% annual return.   

Even if you are away during the day, the returns may not be as impressive, but still exceed bank interest rates.  

Cash option is the Best For: 

  • Homeowners with upfront capital. 
  • Those who are cash-rich and debt-free. 
  • Residents seeking maximum long-term savings. 

How It Works: 

Paying for your solar system outright is the simplest and often most cost-effective way to finance your panels. Here, you pay the full amount upfront, and from that point onward, all the energy savings go directly into your pocket. 

Pros of Cash Payment Method: 

  • No interest or monthly repayment hassles.
  • Full ownership from day one of panel installation.
  • Maximizes return on investment.
  • Eligible for federal and state incentives. 
     

Cons of Cash Payment Method: 

2. Green Loans and Solar Loans

Green loans are personal loans offered by financial institutions that prioritize environmental and community support. They come with low-interest rates and are ideal for financing solar panels, energy-efficient windows, heat pumps, and air conditioning.    

These loans have flexible repayment periods ranging from 1 to 7 years and typically involve minimal setup fees, low ongoing fees, and no early repayment penalties.  

These loans are suitable for: 

  • Homeowners who want ownership but prefer not to pay up front.
  • Borrowers with good credit history. 

How It Works: 

Many Australian banks and credit unions offer green loans specifically for energy-efficient home upgrades, including solar systems.  

For example, if you borrow $5,000 over five years at a 5% interest rate, your monthly repayments would be around $94. Your electricity bill may be reduced by $100 or more monthly, potentially offsetting the cost entirely. 

Pros of Green Loans & Solar Loans: 

  • Lower interest rates than personal loans.
  • Flexible repayment terms of typically 1–7 years. 
  • Allows you to own the system.
  • It can be used for batteries and other energy upgrades. 
     

Cons of Green Loans & Solar Loans: 

  • Requires a good credit rating.
  • Still involves debt and interest, even though the rate is relatively low.

3. Solar Leasing and Power Purchase Agreements (PPAs)

  • System of Solar Leasing in Australia 

Solar leasing is a payment plan where residential and commercial customers in Australia make monthly payments to a solar supplier for a solar PV system installed on their property.  

Under a solar leasing plan, the system is leased directly from the solar company, and the customer repays the system’s cost over a period of five to ten years. However, interest is charged during the repayment period.   

This results in a slightly higher overall cost compared to the upfront payment.  

  • How Does Power Purchase Agreement (PPA) Work?  

A power purchase agreement (PPA) is a financing option where a company owns and maintains a solar system installed on a homeowner’s property. The homeowner only purchases the energy generated by the system.  

PPAs are gaining popularity due to their low, upfront costs, with homeowners paying a predetermined rate based on the solar energy generated on their property.  

The rates are typically fixed for the duration of the agreement, which can range from 15 to 20 years. 

Works Best For: 

  • Households without upfront capital.
  • Those who want to avoid maintenance responsibility.
  • Renters or tenants. 

Pros of Solar Leasing and PPA: 

  • Little to no upfront cost. 
  • Lower energy bills from day one.
  • The provider covers all the maintenance and repairs. 
     

Cons of Solar Leasing and PPA: 

  • You don’t own the system.
  • Long-term contract commitments
  • Lower total savings compared to owning.  

4. Buy Now, Pay Later (BNPL) for Solar

BNPL options enable you to spread your solar panel payments over time without incurring interest, typically over 6 to 60 months.  

With some companies, you can get up to $30,000 for solar or battery storage systems, with repayment plans ranging from 6 months to 5 years. 

How BNPL Works? 

Here, the customer chooses a solar system. Then, the BNPL provider pays the solar company upfront. The customer then repays the BNPL provider in installments. 

However, ensure you understand the repayment terms thoroughly. Some BNPL offers can become costly if you miss payments or don’t clear the balance within the interest-free period. 

Perfect Options for: 

  • Budget-conscious homeowners.
  • People looking for short-term finance without interest. 

Pros of BNPL: 

  • Interest-free periods depending on conditions.
  • Quick approval and no deposit are required.

Cons of BNPL: 

  • Admin fees, late payment or other additional hidden fees may apply.
  • After the interest-free period, higher rates may kick in. 
  • Limited availability in some regions.  

5. Government Rebates, Incentives, and Feed-In Tariffs

The Australian Government offers a range of financial incentives that can significantly reduce the cost of going solar. These financing methods reduce your out-of-pocket expenses, making solar energy more affordable. 

Best For: 

  • All homeowners and small businesses 

Some of the Best Rebates and Incentives for Solar Energy in Australia 

  1. Small-scale Renewable Energy Scheme (SRES)

This federal scheme provides STCs (Small-scale Technology Certificates), which are essentially rebates applied at the point of sale. Most installers factor this into their quote. Depending on your location and system size, STCs can save you $2,000 to $4,000 upfront. 

  1. State-Based Rebates and Incentives

Several states offer additional rebates or loans to their residents. For example: 

  • New South Wales: Solar for Low Income Households trial and interest-free loans.
  1. Feed-In Tariffs (FiTs)

When your solar system produces more electricity than you use, the excess is fed back into the grid. Your electricity retailer pays you a feed-in tariff, typically 5- 15c per kWh. These ongoing savings can help you repay your loan or lease more quickly. 

Pros of Solar Rebates: 

  • Reduces the initial cost of installing a solar panel.
  • Long-term energy bill savings.
  • Incentives are available to most Australians.

Cons of rebates and incentives: 

  • Government policies and rates can change.
  • FiTs vary greatly by retailer and location. 

Differences Between Solar Financing Options

Solar Leasing VS Buying: Which is more beneficial for you? 

Well, both leasing and buying solar panels allow homeowners to benefit from utility savings and reduce their environmental impact. However, deciding between leasing and owning solar panels is a crucial consideration, and it depends on your specific situation. 

For instance, leasing solar panels provides a more accessible option for customers who may not have the necessary upfront funds to purchase them.  

The homeowner does not own the panels through leasing, as a third party owns them. That means the leasing company owns the equipment.  

On the other hand, purchasing solar panels requires an upfront investment. Additional credits or reimbursements may be available based on state or manufacturer incentives at the time of purchase.  

However, you can also seek free quotes from Cyanergy for accurate pricing information. 

Which Option is Right for You?

Choosing an appropriate financing method can save you thousands of dollars annually on your energy bills. The choice ultimately depends on your financial position, property ownership status, and long-term goals.  

So, here we’ve done a quick comparison of different types of financing options to make your selection process easier:

Financing Option Upfront Cost Ownership Monthly Repayments Long-Term Repayments Potential Risk Level
Cash Payment High Yes None Highest Low
Green/Solar Loan Low to Medium Yes Yes High Medium
Solar Lease & PPA Low No Yes Medium Medium
BNPL Low Yes Yes Medium to High Medium
Government Incentives & FiTs Not Required Yes No High Low

Wrap Up

Over the decades, people have been using solar power to illuminate their homes, reducing their reliance on fossil fuels and shielding themselves from rising electricity prices. 

Even though solar power ensures your energy freedom and lowers your energy bills, the way you pay for it matters a lot.  

Remember, selecting a specific finance option can make solar an affordable and worthwhile investment, but choosing the wrong one can turn savings into more stress. 

So here’s what you can do next!  

Review your budget and power bills. Determine whether you can pay cash or require a loan. Avoid rushing into lucrative but deceptive offers. Always compare full quotes with repayment details before agreeing to anything.

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow.

Allen Hall: Howard, welcome back to the program.

Howard Penrose: Hey, thanks for having me.

Allen Hall: It’s about time everybody realizes what motorDoc can do. There’s so much technology, and I’ve been watching- Yeah … your Chaos and Caffeine podcast on Saturday morning, which are full of really, really good information about the motorDoc as a company, all the things you’re doing out in the field, and how you’re solving real-world problems, not imaginary ones- Yeah

real-world problems. Oh, yeah. Yeah, and

Howard Penrose: whatever annoys me that week. Exactly. And, and whatever great coffee I’m trying out. Yes. Except for a few. We’ve had the ReliaSquatch down our- Yes … um, a couple of times. Uh, yeah, no, I, I enjoy it, and we gotta get you on there sometime. I don’t do- I, it- … a lot of interviews other than an AI character we put in.

Allen Hall: It’s a very interesting show because you’re [00:01:00] getting a little bit of comedy and humor and s- Yeah … and a, and a coffee review, which is very helpful because I’ve tried some of the coffees that you have reviewed, that you’ve given the thumbs up to. But if you’re operating wind turbines and you’re trying to understand what’s happening on the drivetrain side, on the generator, everything out to the blades even, main bearings, gearboxes- Yeah

all those rotating heavy, expensive parts, there’s a lot of ways to diagnose them-

Howard Penrose: Yes …

Allen Hall: that are sort of like we can look at a gear, we can look at a joint, we can look at roller bearings, whatever, but motorDoc has a way to quickly diagnose all of that chain in about- Yeah … 15 seconds.

Howard Penrose: Well, a little longer than 15 sec- more like a minute.

A minute, okay. It feels like paint drying. But- Uh, in any case, yeah. Uh, uh, and, and what’s kind of funny is, um, back in the ’90s, uh, EPRI actually accidentally steered the technology away from its [00:02:00] core purpose, which was in 1985, um, NAVSEA, the US Navy, had done research on using current signature analysis for looking at pumps, fans, and compressors, the bearings, the belts, the components, all the rotating components using the motor as the sensor.

Not too much different than we are now. I mean, mind you, we got better resolution now, we’ve got, uh, more powerful– I mean, I look at my data from the ’90s, and now it’s completely different. Um, and then Oak Ridge National Lab, same thing, bearings and gears in motor-operated valves. So in 2003, we were the first ones to apply electrical and current signature analysis to some wind turbines in the Mojave Desert.

Wow. Yeah. So, um, nobody had tried it before. Everybody said it couldn’t be done. And, uh, that was a bad thing to say to me because- … it meant I was gonna get it [00:03:00] done. Right. At that time, um, we were looking at bearing issues and some blatant conditions with the, um, with the, uh, generator using a technology called Altest, ’cause I was with Altest at the time.

And, uh, I had taken an EMPath software and blended it with a, a power analyzer, and they still have that tool to this day. I was using that technology all the way through 2015. 2016, I should say. And then- And then switched over to the pure EMPath, which was more of an engineering tool. And then more recently, in 2022, uh, made the decision to ha- to take all the work we’d done on over 6,000 turbines, uh, looking at how we were looking at the data and what we were doing on the industrial side, and took a, uh, created a current signature analyzer that would do one phase of current to analyze the entire powertrain.

Allen Hall: So when you tell [00:04:00] operators you can do this magic, I think a lotta times they gotta go, “

Howard Penrose: What?” Oh, yeah, yeah. They don’t understand it because they’re used to vibration- Right … which is a point analysis system. Right.

Allen Hall: Vibration at this- Yeah … particular location. Yeah. One spot- Even if it’s- … or a couple

Howard Penrose: spots

triax, they’re reading through material, up through a transducer. Hopefully, they put it above the bearing and not in the middle of the machine like everybody is now, because everybody’s trying to sell a sensor. Right. True. They’re not selling a- they’re not selling accuracy. They’re just selling sensors.

Right. So, um- Yeah … you know, uh, I, I’ll, I’ll even talk about one of the companies here. We’ve got Onyx here, and they do it right. I mean, they’ve been doing it right pretty well because we’ve been doing some of the same towers they’re on, and we can match the data they’re getting. Oh, good. Right? Yeah. Uh, so but they get it in multiple spots, and there’s areas they can’t quite reach, so we’ll detect those areas as well.

So it’s a good melding of two technologies.

Allen Hall: Oh, sure. Sure,

Howard Penrose: sure. You know what I mean? Yeah, yeah, yeah. So when you have electrical signature and you have vibration, but in [00:05:00] cases if you don’t have vibration, we’re a direct replacement.

Allen Hall: Because the generator- I

Howard Penrose: dare say that.

Allen Hall: Yeah. Whichever–

Howard Penrose: I dare say that, um, with- Well, the

Allen Hall: generator is acting as the sensor.

Howard Penrose: The air gap. The air gap in the generator s- specifically, yes. Yeah. Generator, motor, transformer. Right.

Allen Hall: Yeah. So any of those- Mm-hmm … you can clamp onto, look at the current that’s on there. Everything that’s happening on the drivetrain, in the gearbox, out on the rotor- Yep … main bearings, all of that creates vibration.

Creates a torque. T- a, a torque. Yeah. Yes, more exactly a torque. Yeah. And that’s seen in the generator, in the current coming out of the generator. Yes. So those signals, although minute, are still there. Yes. So if you clamp onto that current coming out of the generator, you’ll see the typical AC sine wave sitting there.

But on top of that- Is all the information about how that drivetrain is doing

Howard Penrose: Absolutely, and everything else. Anything electrical comes through [00:06:00] that. So what you do is just like vibration, you do a spectral analysis. So every component has a frequency associated with it, just like vibration. It’s, as a matter of fact, I, I keep having to try to explain to people electrical and current signature analysis is no different than vibration analysis.

It’s the same concept. We use the same tools. The signature looks just a little different. It’s a little noisier, um, but you need that noise in order to see everything. But we have a time waveform, and instead of, um, inches per second or millimeters per second, whatever, you know, uh, velocity, acceleration, and displacement, uh, what we end up with is decibels is the optimal method.

You can look at straight voltage signatures at those points or, or current signatures, but the values are so small that you have to look at it from a logarithmic standpoint. Right. There are some benefits to it versus vibration, and there’s some things that aren’t as good as vibration. [00:07:00] So, you know, we, we do…

You have to… Any technology is gonna have their strengths and weaknesses. Sure. So we will see everything all at once. Load doesn’t matter. Right. Speed doesn’t matter. It’s… Only reason speed matters is the location of the frequencies. Uh, so the higher the resolution, meaning the longer you take data, the less chance you have on a lightly lo- loaded machine of blending the peaks together.

Right. Um, on the flip side, if I have two bearings turning at the exact same speed, I couldn’t tell you which one it is. Because they’re the same. Right.

Allen Hall: And the mechanical features of that bearing is w- what creates the signal that you’re measuring. Exactly. So if a bearing has five rollers versus 10, just imaginary thing.

Yeah, yeah. Five rollers versus 10 has a different electrical signature, so you can determine, like, that bearing, that 10 roller bearing- Yes … has the problem, the five is fine. Yes. Yeah. That’s the magic, and I think people don’t translate the mechanical world into the electrical world. That that’s what’s [00:08:00]happening.

They,

Howard Penrose: they don’t because, because what’s happening is they named it wrong.

Allen Hall: Yes.

Howard Penrose: A majority of our users are mechanical folks. Sure. Our vibration analysts and stuff like, ’cause they know how to look at the signatures. Right. Everybody tries to force it on their electrical people, and electrical people go, “We don’t know what this is.”

Yeah. And it’s, it’s, it’s a matter of that training and, and, you know, in the electrical world, you’re not taught to look at that. Right. Yeah. It doesn’t matter. Mechanical world, you’re taught to look at that. So our intern, we were trying to bring in electrical engineering interns and found out that just wasn’t working.

So last year, I brought in my first, uh, intern that’s, you know, he’s been with us now since I brought him in. Okay. Uh, and, uh, Amar, and, uh, you know, he’s helped us develop our vi- uh, vibration software to go along with it. Guess what? It’s the same thing. It’s the exact same sy- system Um, but we just take in a vibration signal instead.

But he picked up on it immediately as a [00:09:00] third-year college student. I can take somebody with a decade as an electrical engineer with a PhD and they can’t figure it out.

Allen Hall: Well, because you’re, you’re taking real- Because it’s different. Yeah. It’s r- well, it’s real-world components-

Howard Penrose: Yeah …

Allen Hall: creating electrical signals.

That’s hard- Well, you have- … to process for a lot of people. Yeah,

Howard Penrose: yeah. It’s

Allen Hall: just not

Howard Penrose: something that we do every day. But that’s… If they, i- if we sa- i- i- if you’re looking at vibration and you start looking at the sensor, it gets complicated too, ’cause guess what? It’s an electrical signal. Right. It’s, it is technically electrical signature now.

It’s converting a

Allen Hall: mechanical signal- Right … into an electrical signal, which is what’s happening in the generator anyway. Yeah.

Howard Penrose: Whether it’s a piezoelectric cell that’s generating a small signal- Yeah … on top of a small waveform that you then take out, you demodulate, uh, or it’s, uh… So you take that carrier frequency out, or it’s a MEMS sensor, which is the same thing.

You know, the, it just sees some slower s- It, it does more of a digital output. So you, you, you know, you have those, or you [00:10:00] have this, which just basically uses a component of the machine to, to, as its own sensor. There is one other difference between them, too, and, uh, I find this very useful when I’m going out troubleshooting something that other people can’t figure out, uh, ’cause we use all the technologies.

So in this case, it would be, uh, the structural movement. Okay? So, so say I have a generator and there’s something wrong with the structure, and the whole machine is vibrating. So y- well, if I put a transducer on it, they might think that’s vibration or something else. We don’t see it. Right. We only see directly exactly what’s happening with the machine.

Sure. So a lot of times when we go in to troubleshoot something that people have done vibration on and everything else, it’s been pro- a, a problem for them for years. We walk in, and all of a sudden we’re identifying whether it’s the machine or it’s something else right off the bat. Then we can take a look at the vibration data and [00:11:00] say, “Okay, it wasn’t the bearing or the bearing, um, structure.

It was, you know, the mounting.” Right. It wasn’t

Allen Hall: fastened

Howard Penrose: down properly. Yeah,

Allen Hall: yeah. Right.

Howard Penrose: Go tighten that bolt. Right, exactly.

Allen Hall: Well, I mean, that’s the cheap answer. Yeah. I’d rather tighten a bolt than rip apart a motor or a generator- And, and- … every day …

Howard Penrose: and that’s the whole point. Now, there are other strengths that go with it.

So for instance, on the powertrain of a wind turbine, I can tell you if you’ve lubricated the bearings correctly. Wow. Because part of what we do is we do take those electrical signatures, and we convert those over to watts. Watts is an energy conversion. Sure. So you see that as heat or some type of loss.

So whatever, whatever’s being lost there is not being sent to the customer. To the outside. Right. Making money. So, um, if I’m taking a look at, say, a main bearing, I might see watts or kilowatts of losses. So you’re gonna have some ’cause you have friction, right? But when we see it increase on, say, a roller, [00:12:00] or the rollers, or, or the cage, that’s usually an indicator that I have a lubrication issue.

Or if we only see it on the outer race, that means that they didn’t clear out all the old grease when they were lubricating it, ’cause the rollers then have to ride across it- Right … ’cause it dries up.

Allen Hall: Sure.

Howard Penrose: Uh, and will carry contaminants. So if you see that, you go up, clean it up, you’ll extend the life of the bearing.

Absolutely you will. Without having to do a lot of work. So, uh, we, we look at our technology as more so early in the, in the stage of a condition. I don’t wanna call it failure, ’cause it’s not a failure. It’s something that’s mitigable. And I made that word up. You can mitigate it. Meaning you can go up and correct it and extend the life of that component.

Sure. Uh, in gearboxes we’ll see problems with, um… Well, the, the one we’re talking about here a fair amount is all the circulating currents going on uptower. We did that research. The current signature analyzer we have is a direct result of doing wind turbine [00:13:00] research just on circulating currents uptower, ’cause we conferred everything over to, to sound at 48 kilohertz.

And so that gives me a 24-kilohertz signal. That high-frequency stuff, which we’re researching in CGRE, and IEEE, and IEC, is called supra harmonics, which I– we talked about that before. Yes, we have. Yeah. And, uh, so when you start seeing that in the, in, in the current that’s circulating uptower because the ground that goes from the top of the tower down is for- DC

lightning protection. And lightning protection, yeah. It’s not meant for, um- Not for

Allen Hall: high frequency- Yeah …

Howard Penrose: currents. Yeah. Uh, we, when we measured it, when we mapped out dozens of towers of all different manufacturers, we found that the impedance about halfway down the tower is where it ends. Sure. The, the resistance.

And then the increased, uh, the high-frequency noise turns any of your shaft brushes into resistors. And at about 15 kilohertz, no current is [00:14:00]passing through them. It’s all passing the bearing, which becomes more conductive the higher the frequency. So with 60% of main bearings failing due to electrical currents, it’s actually currents that are circulating uptower.

It’s not static. There is some static up there, but it’s not static. It’s coming from the controls, the, the generator, and everything else. Inverters,

Allen Hall: converters.

Howard Penrose: And we’ve seen up to 150 amps passing through a, through a bearing.

Allen Hall: So I– We run across a lot of operators who have been replacing main bearings, and they don’t know the reason why.

Yeah. And I always say, “Well, call Howard at MotorDoc because I would almost bet you you have the f- high frequency running around uptower in the nacelle- And the next main bearing you put in there is gonna go the same way as the- Yeah … first one you put in there. Until you cut off that circulating current and then the cell, you’re just gonna continue with the problem.

Then you haven’t eliminated the problem, you’re just fixing the result of that problem. Yes. But it takes- Yeah, you’re, you’re- How, [00:15:00] how, well, how long- You’re replacing

Howard Penrose: a fuse.

Allen Hall: Right, you’re replacing a fuse. Yeah. How long does it take you to s- to determine- An expensive fuse. Yeah. Yeah. Oh, yeah, ’cause you’re taking the rotor down.

Yeah. Well, how, how fast can you determine if you have harmonics uptower that are gonna be causing you problems? 120 seconds.

Howard Penrose: Okay.

Allen Hall: So that’s the thing. I think a lot of- I mean,

Howard Penrose: that’s of the actual data collection time. So you clamp on uptower, uh, and then you can… Well, the way we have it set up now, you just tell it you wanna collect data every five s- uh, five minutes, and then you go downtower, let it collect its data, go back up, grab it.

Um, it’s like…

It’s huge. It’s this size. So, um, and then you connect- It plugs into a laptop. Yeah. Plug it into a laptop or any type of tablet. Um, it, it’s Windows now. I’m trying to get away from Windows. We’re gonna have Linux systems, uh, as well. Uh, and then you use that to, um, just collect that data, and then you press another button.

Now it pops up, and it tells you if you’re in danger or not, [00:16:00] the amount of current passing through the bearing, and the frequencies all the way out.

Allen Hall: So the ideal is you’re gonna have this kit with you in the truck. Yeah. And as you see these problems pop up, you’re gonna clamp on uptower. Yep. You’re gonna measure these circulating currents, and you’re gonna know immediately if you have another mechanical issue, a, a lubrication issue- Oh, yeah.

It’ll look at- … some kind of alignment issue, or- You’ll get all

Howard Penrose: of this information at once. So you- Right … if you go on the power side. So certain turbines, like anything that has the transformer downtower, you don’t have to climb. Right. GE. I mean, I don’t climb. So, uh, uh, you know, th- and that was part of the, the concept behind when we started down this path because I’ve been in the wind industry since 1997.

So one of the things I always saw was, and, and we talked about even, you know, here when it was called AWEA, and we were talking always on the health and safety side about wearing out the technicians. Um, so we discovered that, you know, what was it? Almost 60% of the [00:17:00] turbines you didn’t have to climb. Right.

Oh, yeah. And even the ones you do, you go up, you set it up, and it’ll tell you where you need to focus. The other thing in the powertrain, let alone the generator, when we do a sweep of a site– Now, if we do a straight electrical signature analysis, I’d term that one as a technician’s tool. Sure. That’s more of an engineer’s tool.

Uh, a lot more data, a lot harder to set up. But even though I’m saying harder to set up, it’s still pretty easy. It’s still minutes. Right. Yeah. Most technicians will collect data with, like, a couple hours worth of training. Yeah. You g- You basically gather that data, and if you’re getting a site, so we’ll go out– I love going out in the field.

So we’ll go out in the field, especially if it’s a tower we don’t have to climb I’ll knock out, uh, well, let’s just say I’ll, I’ll, I’ll name one. Say a GE 1.6. I’ll knock out one of those every eight to 11 minutes, depending on how you get to the tower.

Allen Hall: So that’s a full diagnosis of drivetrain- Yeah … plus anything odd happening- Yep

with circulating currents and all that [00:18:00] can- Oh, no, no. Circulating- Or just- … current, that’s a- That’s a separate thing at tower … separate study that- Okay … you have to do that uptower. But anything, anything drivetrain-wise, you can be in and out- Yeah … in a couple of minutes. Yep. Okay. So there’s a lot of operators that have end-of-warranties coming up, right?

Yes. There’s been a lot of developments, so they’re kind of running into the end-of-warranty, and they don’t know the health status of their drivetrain. Same thing for a lot of operators that are in- Yep … full service agreements, and they’re questioning whether they’re getting their money’s worth or not.

Yes. I always say, “Call Howard at Motordoc. You guys can have a whole site survey done maybe in a couple of days, and you will know all the problems that are on site for the lowest price ever”. Yeah. It’s crazy how fast you can do it and how accurate it is. I talk to operators that use your system, so I hear you.

Yeah. Your podcast, listen to your podcast, I’m calling your customers to find out what they say, and they love it. Oh, yeah. They can’t believe how accurate it is. Yeah. Well, the thing about that is we as an industry need to make sure that our turbines are operating at [00:19:00] maximum efficiency. Yep. And if a simple tool like the Motordoc EMPath system exists, we need to get customers, operators in line to start doing it worldwide.

Australia- Oh … Europe-

Howard Penrose: Yeah. We- … Canada. Australia, we’re trying to get into, but right now we even have OEMs using it through North- That’s good … and South America, Asia. Good. Uh, Middle East, um, and, uh, and some of Europe. Good. So it’s, it’s, it’s really taking off. Uh, I’d say probably our biggest market right now is Brazil.

Sure. They’re going crazy. Well, the, the turbines are- They’re having a lot of problems. Yeah.

Allen Hall: Right. And the, well, those turbines have a h- high usage, right? So because- Oh, yeah … the winds are so good, they’re operating at, like, capacity factor is above 50%. Yes. It’s insane. Yeah. So there’s a lot of wear and tear.

There’s no downtime for those turbines.

Howard Penrose: Yeah. Well, and, and people think it’s all the starting and stopping. It’s not. No. It’s a grid-related issue. So we have- Sure … we have a low frequency. And you know some of the stuff I volun- I, I’m, I’ve been volunteered for- [00:20:00] Yeah … uh, including the CIGRE thing. Um, so I get to sit in the grid code committees for IEEE and put my, and our input into that, uh, and kind of watch the back of the IBR industry, right?

Mm-hmm. ‘Cause there’s a definitely bias against our industry. Um, and I also, uh, get to hear what’s going on in the grid side of things from CIGRE worldwide, and it’s all very similar, and it has to do with low-frequency oscillating currents- Yes … called subsynchronous currents- Yes … which are low enough not to damage large synchronous machines.

And they thought, and there’s books written on this, by the way, multiple books written on wind turbine impact- Uh, and they’re seeing now, um… Well, we detected it first, along with Timken. Hank, uh, and, and I went out to a site, and we detected for the first time, because of how they wanna do the testing and where the site was located, we saw the oscillating torque [00:21:00] in the air gap, ’cause that’s one of the things the technology does.

It actually measures the torque, air gap torque. Sure. So we were watching the oscillating torque as a tower started up. And so we did, we went through the rest of that site looking at the same stuff in the same way. It increased our time and data collection, and time on site. But then we started looking for it at other sites, and going to pass data because I don’t have to go back and retake data.

Right. And we’re like, “Oh my God. It’s everywhere.” 16 hertz, 21 hertz, and 50 hertz. And we found a paper that specifically identified that as the sub synchronous frequencies for 60 hertz. So we know what they are also for 50 hertz. Once we identified that and we saw how much the torsi- torque was oscillating, we worked with Shermco, who got us some information on Y-rings that were failing.

Yeah. And they were all failing… When the metallurgy was done, they were all failing from fatigue. And you’re like, fatigue how? What’s fatiguing these connections? [00:22:00] Well, the fatigue is that air gap torque- Exactly … because you’re basically causing the, the, everything to oscillate a little bit, and that causes the windings to move slightly.

It’s a living,

Allen Hall: breathing machine-

Howard Penrose: Exactly … this generator

Allen Hall: is.

Howard Penrose: Yeah.

Allen Hall: It’s not

Howard Penrose: static. It’s definitely not sta- no electric machine is static. No. Even a transformer’s not static. Right.

Allen Hall: So- There’s a little

Howard Penrose: bit of wiggle going on there all the time All the time. And it’s minute, so it takes a long time. Right. And what, uh, uh, everybody…

Well, first people thought it was a particular manufacturer, which it wasn’t. Turned out every defig’s failing the same way. Sure. You’re fatiguing it. Yeah. Every bearing is failing the same way, even in the gearbox, main bearings, and everything else. Right. All of these conditions are happening across all the OEMs, but they’re not allowed to talk.

Well, this is, this is the thing that

Allen Hall: I like watching your podcast.

Howard Penrose: Yeah.

Allen Hall: The Chaos and Caffeine. It comes out Saturday mornings. It’s on YouTube. If you haven’t- Yeah … clicked into it, you should click into it

Howard Penrose: because a lot of these issues are discussed there. It’s definitely, um… [00:23:00] Let’s just say I’ll speak Navy quite a bit.

Allen Hall: It’s a great podcast, and I think what you’re doing with the EMPath system- Yes … at motor dock is really a game changer. Yeah. I’m talking to everybody, all the operators I know. I keep telling them to call you and to try the system out because it’s so inexpensive and it does the work quickly and efficiently, and it’s been proven.

There’s no messing- Oh, yeah … around when you’re talking to MotorDoc. I…

Howard Penrose: Somebody dared tell me that there’s no standard for it. There’s ISO standards for it. Yes. There’s IEEE 1415- Yes … which I chair. Uh, and there’s other standards coming out- This is- … associated with it. And there’s a document that I also chair for Sea Gray- Called A178, which is the practical application of the technology.

So it’s well-documented. There are traceable standards for it. I need more

Allen Hall: operators to call you- Yeah … and to talk to you and get systems in the back of the trucks that they can use to check out the health of their gear boxes and their drive trains and their generators. How [00:24:00] do they do that? Where do they go?

Where, where’s, what’s- Well- … the first place they should look for?

Howard Penrose: Uh, info@motordoc.com. Okay. I get all, I get all of those as well, so do my people. Um, or, uh, LinkedIn. LinkedIn’s really good.

Allen Hall: Look up anything. Yeah.

Howard Penrose: Yeah, yeah. So, so either the company at Motordoc, or, uh, I’m, I sh- I’ll show up either searching for my name or, uh, linkedin.com/in/motordoc.

Come straight to me ’cause I’ve been in, on LinkedIn forever, so- Right, just- … I got to do that … look up

Allen Hall: Howard Penrose, P-E-N-R-O-S-E. Yep. Or go to motordoc.com is- Yep, motordoc.com … the website address.

Howard Penrose: Yep. There’s a lot of great information there. And we have partners, and we have people. We’re growing the company.

You know, talk to me. I, I’ll- Yes … I like answering the phone and talking. It’s, it’s a thing. My people go, “Can we answer the phone one?” No. Um, but, but yeah, we, we, y- when you call us, you’re not just dealing with a single person. Right. The Motordoc is far more expansive. Right now, we [00:25:00] just got our partnership with, uh, Hitachi and, and Juliet- Yeah, that’s great

and stuff like that. Uh, we’re helping them with certain things. Uh, we’re partnered with some of the big OEMs, almost all of them, um, you know, helping identify the issues, you know. And, and when users contact us, often they’ll tell us what’s going on, and we’ll, we can, uh, sometimes say, “Yeah, it’s this, and here’s how we prove it.”

Allen Hall: Yeah. That’s the, that’s the beauty- Yeah … of calling Motordoc. So I need my operators that, that watch the show- Yeah … worldwide, go online, go on LinkedIn, get ahold of Howard, get ahold of Motordoc, and get started. Yep. Howard, thank you- And- … so much for being on the podcast. Yeah. This is fantastic. I love talking to you because-

it’s, it’s like talking to, you know… Uh, no, really, it’s talking like someone who’s a real good industry expert, who’s been there a long time, and understands- Yeah … how this

[00:26:00] works.

JD Vance and His Certainty Re: God’s Work

At left we see illustrated the core problem with the world’s theistic religions, i.e., that adherents are so certain of the rightness of their beliefs that they have no problem destroying the world.

FWIW, I have a friend who takes this even further: he is actively rooting for the apocalypse, and the prospect that all believers in God’s son Jesus will be raptured up to heaven to sit at the right hand of God.

He knows that I don’t believe any of this, but he remains confident that I’ll come around.  As he told me, “God melts even the hardest of hearts.”  He thinks I’m doing the devil’s work with my compassion for others and the effort I put out to achieve a peaceful and sustainable civilization.

We’d be living in tough times even without these fanatics, but religious dogma, especially of this sort, makes it all that much more difficult.
