Have you ever wondered, “How much energy does one solar panel produce in Australia?” Or maybe you’ve asked yourself,
“Can one panel really make a difference on my energy bill?”
These are the kinds of questions that thousands of Australians ask every day when considering a switch to solar.
Undoubtedly, with Australia’s rising electricity costs and abundant sunshine, solar power has become an integral part
of
our everyday lives.
Quietly, panel by panel, it’s showing up in suburbs, small towns, and even off-grid shacks, helping Aussies take
greater
control over their energy use and, most importantly, their power bills.
However, before making the costly investment in a complete system, it’s smart to understand the basics, such as how
much
energy a single panel actually produces in Australia.
The truth is, there is no universal answer that applies to every solar panel. From blazing outback regions to cloudy
coastal towns, your geographical location matters. This could make a real difference.
So, let’s break it down and figure out what one solar panel can do to power your lifestyle!

How to Ensure Your Solar Panels Are Working Efficiently?
Some Key Factors: Know Before You Buy!
Before determining how much power a solar panel generates, you must understand a few basic terms. This includes:
- A kilowatt (kW) is a unit of electrical power equal to 1000 watts.
- Kilowatt Hours (kWh) is the amount of electrical energy consumed in one hour, which equals 1000 watts.
- Direct current power (DC) is the energy generated by a solar panel.
Solar Panel Technology: A Look at the Different Types
To fully comprehend solar panel output, you must first understand the type of panels used. Solar panels are
classified
into different types. However, the most common types of solar
panels installed in Aussie homes are monocrystalline and
polycrystalline.
The reason?
Well, Monocrystalline panels are more efficient and can produce more energy. Although they have higher initial costs,
monocrystalline panels are the best as they can produce more solar energy in warmer temperatures or shaded areas.
On the flip side, Polycrystalline panels are less energy-efficient
than monocrystalline panels but are more
cost-effective. They also perform less effectively at higher temperatures.
So, choosing the right solar panel for your home will help you maximize
efficiency. You can use the sun’s power with an
efficient, high-quality solar panel.
The Science Behind Solar Panels| How Sunlight Becomes Electricity?
We all know that solar panels convert sunlight into electricity, also known as photovoltaic (PV).
They are composed of numerous solar cells, which are made up of semiconductor materials such as silicon.
But how does a solar panel actually work? Let’s see!
A solar panel works by converting sunlight into electricity through a process known as the photovoltaic effect. When
sunlight falls on the panel’s surface, the solar cells made from silicon absorb sunlight and release electrons.
These moving electrons create an electric current, which is captured and can be used to power homes, devices, or
stored
in batteries. Essentially, solar panels convert sunlight into usable electrical energy in a clean and sustainable
way.
From Sunlight to Electricity
The electricity generated by solar panels is direct current (DC). However, in Australia, households and businesses
use
alternating current (AC) to run the appliances. Therefore, the conversion from AC to DC is necessary when generating
electricity using solar energy.
This conversion is done by a device called a solar
inverter. Once converted, the electricity can power appliances,
charge electric vehicles,
or be stored in a battery for later use.
What is the Output of a Solar Panel?
The amount of DC power solar panel systems produce under ideal conditions is used to rate them. It is measured in
watts
(W) and represents the power your panels can produce.
Most residential solar panels have power ratings ranging
from 250 to 400 watts, with higher power ratings preferred over
lower ones. Under the same conditions, higher-wattage solar panels generate more electricity than lower-wattage
panels.
Is It Necessary to Store Solar Energy in Australia?
Whether you are in Australia or any other part of the globe, adding solar battery storage can be a game-changer to
your
energy system.
While solar panels produce electricity during the day, energy needs often extend into the night. However,
renewable
energy sources
are intermittent in nature, meaning they cannot generate power continuously.
And there comes the battery, which stores the excess electricity produced during the day and illuminates your home
when
the sun isn’t shining. It ensures a reliable, steady supply of solar energy, even after sunset.
From ensuring greater energy independence to reducing household energy
consumption, integrating battery storage can help
you fully leverage the benefits of solar power.
Calculating the Energy Produced by One Solar Panel
To calculate how much energy one solar panel produces, you multiply the number of sunlight hours by the panel’s wattage.
Most residential solar panels in Australia are rated between 250 and 400 watts, meaning they can produce that amount of direct current (DC) power under ideal conditions.
Here’s the formula for calculating panel output:
- Hours of sunlight x Wattage of your solar panel = Solar panel output
For example, if a 350 W panel receives 4 hours of full sunlight, it would generate 1.4 kWh of electricity in a day.
4 hours × 350 W = 1400 Wh or 1.4 kWh.
Therefore, in Australia, where average daily sunlight hours range from approximately 3.5 to 5, depending on the location, a single panel typically produces 1.2 to 1.8 kWh of energy per day, or roughly 500 to 650 kWh per year.
This makes the wattage of each panel a key factor in both energy output and the total cost of a solar system, as solar pricing is often calculated in dollars per watt.
Maximizing Solar Panel Efficiency | Get the Most From Your System!
In Australia, maximizing solar panel efficiency involves more than just installing panels and hoping for sunny days. It requires thoughtful planning and regular maintenance to ensure your system performs at its best.
The key factors include:
- Orientation and tilt
The tilt angle of your solar panels can also impact their efficiency. Therefore, ensure your panel faces the sun for the longest period each day, typically north-facing in Australia.
- Shading
Shades from trees, buildings, or other obstructions can significantly reduce power output. So, it’s crucial to install panels in a clear, unobstructed area, which will increase their energy output.
- Maintenance
Keeping panels clean and free from dust, bird droppings, or debris also helps maintain maximum energy absorption. Regular cleaning and maintenance keep your solar panels at peak performance for years.
- Temperature & Efficiency Losses
Do you know that excess heat reduces panel efficiency?
Moreover, additional losses from wiring, inverter inefficiency, dust, and installation issues can further reduce output.
For instance, a 250 W panel might produce nearly 186.7 W under real conditions.
- Season & Weather
Summer yields more energy, whereas winter and cloudy days significantly reduce output, even if panels still generate power.
- High-Quality Components
Using high-quality components, such as inverters and monitoring systems, allows you to track performance and quickly identify issues, thereby eliminating the risk of excessive damage and costly repairs.
Lastly, battery storage can enhance overall efficiency by storing excess energy for use during periods of peak demand or at night.
By paying attention to these factors, you can significantly increase the return on your solar investment and reduce reliance on the grid.
While the energy output of a single solar panel can vary, it’s clear that solar panels can significantly reduce reliance on traditional energy sources and contribute to a greener future.
Long-term savings on energy bills can offset the initial investment in solar panel installation.
So, if you’re considering switching to solar energy, now is a great time to take advantage of Australia’s sunny climate and harness the sun’s power.

Top 5 Benefits of Solar Energy for Australians
Australia, the sun-soaked continent, is increasingly popular for the power of the sun to fuel its future. Solar energy, a clean, renewable, and abundant power source, transforms how Australians live and work.
The following benefits are mentioned to inspire more Australians to join the sustainability revolution.
Significant Cost Savings
One of the most tangible benefits of solar energy for Australians is the significant cost savings it offers.
With the sun as a free and abundant energy source, Australians who have installed solar panels enjoy reduced electricity bills.
According to the Australian Photovoltaic Institute, a typical Australian household can save up to $540 per year on electricity bills by utilizing solar energy.
Energy Independence
Solar energy is helping Australians achieve energy independence. Households and businesses can generate electricity by installing solar panels, reducing their reliance on the grid.
This energy freedom also provides energy security, shielding Australians from fluctuating energy prices.
Job Creation
According to the Clean Energy Council, the renewable energy sector, led by solar, employed over 25,000 Australians in 2020. As the industry continues to grow, it is expected to create even more jobs, boosting the Australian economy.
Environmental Sustainability
Solar energy is a clean and renewable source of power. Australians reduce their carbon footprint by using the sun’s power and contribute to a more sustainable environment. Solar energy produces no greenhouse gas emissions, making it a key player in Australia’s efforts to combat climate change.
Increased Property Value
According to a study by the University of Melbourne, homes with solar panels sell for an average of 3.8% more than comparable homes without solar panels. This makes solar energy an environmental investment and a smart financial decision.
Government Incentives and Rebates on Solar Energy
The Australian government offers a range of incentives and rebates to encourage the use of solar energy. These
include
the Small-scale
Renewable Energy Scheme, which provides certificates that can be sold to recoup a portion of the
cost of
installing solar panels.
This makes solar energy an even more attractive option for Australians. From significant cost savings to
environmental
sustainability, the benefits of
solar energy for Australians are clear.
As the country continues to harness the sun’s power, these benefits are set to grow, making solar energy an
increasingly
important part of Australia’s energy future.
With the government’s support and the industry’s growth, the sun shines brightly on Australia’s solar energy
landscape.

Profound Nihilism?
Normally, “nihilism” means the belief that life is without objective meaning, purpose, or intrinsic value. Trump was elected by mean-spirited idiots, but they could hardly be called “nihilists.” For example, they believe very strongly in white supremacy, the dismantling of the federal government, saving people from the lethality of vaccinations, etc.
Now, there is a secondary meaning to the word, i.e., those who reject established social systems. In this sense, I suppose they are indeed nihilists, in that they reject lawfulness, honesty, human rights, truth, science, tolerance, and compassion.

Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall, and I’m here with Rosemary Barnes, Matthew Stead, and Yolanda Padron. And three out of the four of us will be in Melbourne Australia talking to a number of operators and interested parties about WOMA 2027. Matthew, where will we be the couple of days we’re in Melbourne?
Matthew Stead: So, um, first of all, we’ve got the Pullman, uh, East Melbourne, which is, uh, where the venue will be for, for 2027. Um, so that’ll be our home base. Um, we’ve got around about eight meetings planned already. So what we’re doing is we’re talking to the operators and a few other industry, um, players about [00:01:00] what we need to talk about, how we’re gonna move the industry forward in Australia.
Uh, so it’s gonna be jam-packed, but there’s a little bit of time left on the Friday afternoon if there’s any late-minute, um, people that wanna get in contact and catch up with us, um, for next Thursday, Friday, or actually Friday. Uh, so yeah, it’s gonna be a, a jam-packed time. I think we’re gonna be tired, too many coffees, and talking to all the key, all the key operators, uh, about what they wanna hear about and how we can move the, the industry forward.
Allen Hall: And if someone wants to put an input into the WOMA panel about what will be discussed at WOMA 2027, Matthew, how would they do that? How do they get ahold of you?
Matthew Stead: Well, we have a wonderful website, and that’s got all the details you could ever want. Um, you can also register on the website, so please register.
Otherwise, um, I’m sure we’re gonna be a sellout this year for sure. So woma2027.com.
Rosemary Barnes: I just wanna add that when people talk to [00:02:00] me about the event, they always say how they love that the topics are so relevant, and the reason why that they’re so relevant is because we make sure to go around to operators and find out what are the issues that they’re really dealing with.
So anybody that’s thinking of attending, even if you can’t, you know, meet us up, meet up with us in Melbourne, get in touch and tell us what are the, yeah, what are the topics that you’re struggling with that you’re not, um, you’re having trouble finding enough information, having trouble finding the people that can help you.
And y- yeah, like we take all of that information, and that’s how we come up with our agenda each year. And yeah, I mean, for us, that’s the, the main thing is that this has to be really relevant, up-to-date information for the industry, and we need your help to make sure it stays that way. I
Matthew Stead: mean, that’s what we’ve done the last two years, so this is– we’re just repeating the formula, um, listening to the operators and getting the good topics and the good speakers.
Allen Hall: Well, Vestas has had a good quarter. Uh, the, for the last couple of years, honestly, s- [00:03:00] Vestas has been really thin on margins. There was questions about it continuing on. Rising costs mostly, uh, supply chains, especially during COVID, were bad. Uh, and, uh, but for the most part, the shareholders stayed attached.
Well, that story is changing rapidly. The world’s largest turbine maker posted second quarter operating profits of $400- €46 million, more than double what the analysts had expected, and it’s raised its full-year margin guidance alongside half-year results for the first time in a decade. The shares climbed about 20% in Copenhagen, adding roughly €4.7 billion of market value in a single session.
Now, the chief executive, uh, Henrik Andersen, ha- put it plainly to, uh, uh, in a couple of news sources that something much bigger is happening and Vestas is gonna be the, the leader in wind. That’s how I read it, that everybody [00:04:00]at Vestas was super happy with the, the change in direction and things were moving up steadily.
But a 20% jump in a day is remarkable. You don’t see that in large industrial businesses like wind energy. Matthew, this has real implications on what happens next for Vestas because success like this usually means more orders.
Matthew Stead: Yeah, I wonder what’s going on under the hood there. Um, I mean, Vestas is a quality company, although, although can I just do a quick segue?
How many turbines were installed in Denmark in the last, uh, two years? Like last year and the year before?
Allen Hall: I don’t know. How many?
Matthew Stead: I believe it was eight turbines installed onshore in Denmark last year, and the year before it was 12. So, you know, maybe, maybe Vestas needs to focus on their own backyard a little bit as well.
Allen Hall: I’m not sure there’s a lot of opportunity there. Yeah, onshore.
Matthew Stead: How can you ever be full? I mean, there’s always, um, [00:05:00] uh, you know, um, you know, resiting or, um, you know, upgrades and-
Rosemary Barnes: You know what? Allen and I are probably gonna get some time in Jutland, uh, later this year, um, and that area and the old wind turbines there was actually the inspiration for my whole YouTube channel.
It just, ’cause there’s, you know, there’s turbines there from, the earliest one is, um, from the ’70s and still going. I think it’s one and a half megawatts, actually huge for, for that time. Um, and it was like community made, um, at Tvind. But anyway, I’m interested to revisit the site and have a look and see are these, you know, all these old turbines still there.
It’s only, like six years since I went through and did the experience but for the most part, they don’t seem to be yet pulling down the, the small old ones and putting up big ones. There’s a lot of, a lot of them are community owned. Um, and yeah, I mean, Danish people love wind turbines, but there’s only so many that you can have onshore.
Like, people are happy to live near them by, you know, the standards of people in other countries, but you don’t want [00:06:00] one in your literal backyard. I think that there is, there, there is a, a limit to how many more onshore wind turbines that you can get in that area and offshore expansion is the more likely way to go.
Um, and also I think it’s, it’s, it’s good to recognize that if you have a domestic only or a domestic first strategy, that will only get you so far and then you have to expand, and I think Denmark did that really well. I think Germany a little bit less. I think that Enercon were a bit surprised, um, by their strategy.
It, uh, they had a real hard time anyway when they had to transition away from mostly Germany to getting overseas. And obviously, like if you look at China, they have most of their installations are in China. They are trying so hard to get outside of China because it’s not, like even a market as big as China, it’s got decades to go before it will be full.
Um, you can still recognize that that’s not your, like long-term strategy for growth has to involve expansion, I think.
Allen Hall: I think Vestas, regardless of what happens in Denmark, is making a play for the United States. That seems to be [00:07:00] where a significant effort is happening at the moment and on offshore. Their– Vestas seems very excited about the offshore opportunities.
Of course, there’s a ton of wind turbines gonna be installed in the UK and, and all around Northern Europe. Offshore, the opportunities to buy turbines, there’s only a couple that you could get today. Uh, uh, the GE Vernova offerings I, I don’t think are gonna fit the mold, and I don’t know if GE’s even actively selling.
So their competitor realistically is Siemens Gamesa, which does seem like the smaller player at the minute versus Vestas, which is heavily pushing the V236 and will fill order books like crazy, I think, uh, just based upon the, the history they’ve had and everybody knowing who they are. So Also on the move in Australia, right?
Vestas is huge in Australia right now.
Rosemary Barnes: I think it’s really good that their, um, yeah, finances, uh, are [00:08:00] looking a bit better ’cause it’s been funny. Like, I tried early on in my wind career to invest in, you know, wind turbine manufacturers knowing that there would be immense growth, and I was right. There, there was immense growth.
Not that that was so hard to figure out that there would be, but it did not lead to any kind of, um, return on, on anything, you know. Like, that did not keep pace with the just general market. Um, so I, I stopped trying to, stopped trying to invest to that. But it has been really, really hard for the companies to, you know, raise money or y- you know, do any of the things that they need to do because they’ve always, like, they’re growing, growing, growing, but finances has been so tight that it has been a real constraint on the amount of engineering that they could do, and I really hope that Vestas are gonna take this opportunity that they’ve got compared to, you know, a lot of the other manufacturers.
Vestas do have really strong, um, innovation and, yeah, engineering capabilities for doing– you know, developing new technologies and improving them, and I really hope that they’re taking this opportunity to build that up. There are a lot [00:09:00] of very good engineers with a lot of experience in the industry in that area that are working in other fields at the moment because, you know, there’s been a lot of contraction in Denmark.
So I don’t know, it seems like a really good time to hire back some of that really in-depth knowledge and, yeah, get a- get ahead of, you know, some of the future quality problems. We’re going through such a hard time at the moment from the fast development that happened in the 20-teens when there wasn’t a whole lot of money around.
We’re dealing with quality problems now, so, you know, maybe we can get ahead and not have the next round of them if we can invest in just a lot more, uh, engineering capacity.
Allen Hall: When you have success like Vestas has, usually the upper level management and some of the executive team starts getting pilfered, that they’ll get offers to repeat that success at another company, and it sounds like that process has started already.
There’s a couple of executives that have recently departing or are in the midst of departing from Vestas. [00:10:00] I would see that continuing f- at least for the next six months, uh, because everybody wants to repeat that, right? If you can get a 20% increase in your valuation overnight, uh, I can, I can list a number of companies, regardless of industry, that would love to participate.
Even in a 5% increase, that would be remarkable. So, um, Vestas is gonna have a hard time holding onto this. That’s just the nature of the business where things are successful, people will wander. And Rosemary, I, I think they’re– And Yolanda In, in my book, Vestas should sort of s-stand down and just make quality products.
I’m not sure you sh-should tinker too much at the time being and just make the good stuff better. That seems like a way to really increase profits.
Yolanda Padron: Yeah, I mean, solving a lot of the issues that– And, and that’s not just a Vestas exclusive thing, right? All of these OEMs have some sort of issue that maybe– I know Rosie’s touched a lot on, on it, where [00:11:00] you build this version A and then version B solves one of the small little issues, but now it creates another little problem, and then you have version C, and then everything just kinda has its own niche little issue, um, that really expands over time.
So if they could solidify what they already have in, in a, in a model that, that would help them just even keep a lot of their customers, I think that’d be great, and it would help, certainly help them, um, not continuously, like, rotate around the customers, ’cause it almost feels like, at least in the States, right, you, you get GE to be really, really strong and have a huge market share, and then GE starts focusing more on gas turbines, so then they all go onto Vestas, and then they all go onto Ontara now.
Um, and then just, you know, just kind of everybody starts cycling through them because they just kind of want something that’s better quality than what they’re getting in the long haul.
Matthew Stead: Allen, you, you talked about you think there’s something big under the hood. I think you, you [00:12:00] thought that maybe Vestas was angling towards something or being quite bullish.
Do you think that they might take over GE Vernova?
Allen Hall: I don’t think they’re gonna grab Vernova, and I don’t think Vernova is for sale at the minute, but I wonder if Siemens Gamesa is, or Nordex. I mean, Nordex has done terrific the last couple of quarters and is making inroads in places that I didn’t think possible three, four years ago.
Uh, the European marketplace is be- becoming really unique in that sense that there’s a lot of money being put out. But is there a sole perfect solution for Europe? Not at the minute, ’cause you got two competitors there, and then China trying to, to work its way in. Will the Europeans come together and form something more united, even if it’s just a partnership, a loose partnership, versus letting China on the shores?
We’ll see. 64 of the largest machines that Vestas has builds are standing off the German coast, but one blade is missing a [00:13:00] piece. We’ll talk about that when we come back.

Allen Hall: Well, Germany’s largest offshore wind farm is now fully installed, and EnBW confirmed this, uh, past week that all 64 of the Vestas V236 15-megawatt turbines are s- standing at the He Dreiht wind farm about 85 kilometers northwest of Borkum. Uh, 960 megawatts, [00:14:00] 2.4 billion euros invested. Man, these offshore projects are expensive to get installed.
Uh, so it’s power for roughly 1.1 million households, and there’s no state subsidy behind any of it. And so this is a little bit of a u- unique situation. Uh, th- well, the one footnote about the wind farm is they had a V236 blade break and fall into the North Sea, and they had fished it out and I think I passed along s- pictures that I saw online of, uh, one of the police boats pulling the shear web out of the water I don’t know what to think anymore about some of these offshore blade issues.
Obviously, Vestas is very conscientious about it and will be doing RCAs and engineering reviews and all the above to go identify what the problem is. But it does just lead to a little bit of a pause of do– what is going on for some of these offshore [00:15:00] wind blade installations or, or whatever’s causing these blades to break?
Do we have a good handle on it? Yolanda, is– are we following up on all the design details so that we can prevent these things in the future?
Yolanda Padron: I mean, I’d, I’d hope you’d be following up on the design, right? Like, and, um, but I think there is still a little bit of a disconnect from, from what we’ve seen, and again, not just Vestas exclusive, um, between the people who are designing and the people who are manufacturing, the people who are in operations, right?
So, uh- The, from what we’ve heard, uh, this could have potentially been a, um, partially because of a transportation issue, which is what happens a lot in onshore. It’s a lot more common than we would like it to be. Um, and so that even goes beyond what would go on in the design studio and what would go on in the manufacturing and what would [00:16:00] go on even just for the people that are running the site, right?
So, so some sort of, um, in between, uh, EPC error. Um, but yeah, I just think that, like in a lot of industries, there should be a lot more communication between all of these teams on the lower level, so that way a lot of these problems can, can be avoided.
Allen Hall: I’m wondering if it’s actually an issue on the, the testing side.
And, uh, the one question that just popped up, and we saw from the ORE Catapult, uh, survey that’s being conducted at the moment, and if you haven’t participated in that, you just visit ORE Catapult and answer some of the survey questions. But torsion on a blade, which is very difficult to test for, and it really isn’t tested for today, but does happen during the move and the transportation of these big offshore blades.
Is it one area that we need to do a little more work in or maybe spend some more time focusing on it to see what is happening as blades are [00:17:00]moved?
Rosemary Barnes: The thing about te- torsion is that it is much more significant as blades get longer. I can’t, I can’t remember the equation off the top of my head, which is, um, bothering me.
But I think it scales with, like, the fourth power or something of, of length. And so whilst it was always a bit of a problem, it’s much more of a problem as it gets, as blades get bigger. I mean, they’ve never, like, fully tested a blade, and there was always a lot of reliance on, hey, y- you know, like we’ve tested certain things that is possible to test in a test facility on the ground.
But they also rely on their decades of experience of how blades actually behave in the field. But, you know, remember, that’s a real lagging, lagging indicator because y- you know, their decades of experience is mostly with lots smaller blades. Now, blades are really different because they’re longer and different effects are, are taking over.
It’s not just, uh, torsion, but it’s also the laminates get much thicker, and then y- you know, you, you have issues with the way that they’re curing, [00:18:00] and there’s a lot more just space for, um, defects to be present in a really thick laminate All of those things add up. Oh, yeah, then add in addition, like new materials, carbon fiber is new, and then new ways of producing it, you know, pultrusions, um, all kinds of different materials like balsa’s being replaced with foams and, um, like, you know, 10 times that number of what sounds like a small innovation, but all of these things have the potential for damage and don’t have a really long track record in the field to be able to kind of calibrate.
We do need to remember that, like, when you do something new, things are gonna break, uh, sometimes, they’re gonna fail sometimes. If they don’t, then you’re definitely being too conservative, and your product is costing more than it should, and nobody wants more expensive wind energy, right?
Matthew Stead: Rosie, Rosie, I, I know you’re doing some, some excellent work on, um, industry studies around erosion and temperature and so forth.
Um, I just wanted to let a little secret out of the bag that, um, in the future there will also be some [00:19:00] other studies on torsion and blade twist and blade dynamics. So, um, just a few things are in, in train at the moment, which I can’t share, share, but, uh, watch this space around better understanding blade twist.
Allen Hall: The Hydride wind farm runs on European turbines, but the next one might not. Two governments with two very different answers on who gets to build Europe’s wind fleet.
Delamination and bondline failures in blades are difficult problems to detect early. These hidden issues can cost you millions in repairs and lost energy production. CIC NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss.

Well, two countries and two decisions, one question. In Scotland, the UK government blocked plans for the Chinese manufacturer Mingyang to build a turbine factory, uh, near Inverness on national security grounds. 1.5 billion pounds of investment, up to about 1,500 jobs. And First Minister John Swinney has asked the new prime minister to reconsider.
And the UK energy secretary minister called that request irresponsible. Meanwhile, up in Denmark, Vattenfall has just won two offshore wind farms and will not say whether it will buy European turbines. Danish suppliers are not taking that quietly. So [00:21:00] the Scotland question about the Mingyang factory is at least being discussed again with the new prime minister in the UK.
It does seem like there’s a lot to do and get the government formed and make all this stuff happen. But I don’t see a Burnham administration changing the outcome for Mingyang, but I could be wrong. At the, the same time, Vestas is pushing for a more Eurocentric focus and to really keep out the Chinese.
Uh, something has to give here pretty soon.
Matthew Stead: I actually think Mingyang should, um, set up a factory in Scotland. I, I mean, what’s wrong with that? I mean, uh, why is that a security issue?
Rosemary Barnes: Set up the factory and put the, like, whatever you’re worried about, put protections in place for it, require it to be a local joint venture or whatever.
You know, we’ve seen the blueprint in many of what used to be, you know, less rich countries. That’s how they, you know, got a head start on some of these technologies. It’s not like, I don’t think that China [00:22:00] has a head start on wind, wind turbine technology, but they certainly have different ways of doing things that, um, yeah, we could, we could learn from.
But I think across the board, wind turbines, batteries, solar panels, whatever, let them set up factories, put the rules in place that mean that your country benefits from it and you’re getting the, you know, the information transfer.
Yolanda Padron: Do you think that’ll, like, impulse a lot of these more established European companies to maybe start fixing some of the issues that they’ve known about for, for a while, um, particularly regarding the blades and everything that we’ve talked about earlier?
Like, there’s enough competition there, so maybe they need to start looking a little bit more deeply into their problems.
Allen Hall: Do we think that Chinese operations have been out front, forward, honest, I’ll even use, about their blade issues?
Rosemary Barnes: No, but this is a good way to find out, isn’t it?
Allen Hall: Governments decide who is allowed to build a turbine after a discussion on Scotland.
Uh, but, but [00:23:00] occasionally, a court decides what a turbine legally is. India has just settled that question, and the reasoning should be of interest to anybody who ships machines across a border right after this. As wind energy professionals, staying informed is crucial and let’s face it, difficult. That’s why the Uptime Podcast recommends PES Wind Magazine.
PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future. Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t miss out. Visit peswind.com today. A tax fight in India has produced a definition every turbine supplier should read.
Is a wind turbine bolted to a concrete foundation movable goods, or is it immovable property? State tax authorities argued immovable, which would have [00:24:00] taxed erection and commissioning contracts at 18% instead of 5%. The Andhra Pradesh, uh, High Court disagreed, and on the 12th of August, the Supreme Court declined to interfere.
The reasoning rests on something this whole industry takes for granted. A turbine can be taken down, moved, and put back up. So a turbine is a movable object, and it has less taxation. Bonus. So this is a really interesting discussion that’s happening in India because it’s probably symptomatic of things we’re seeing elsewhere across the world about taxation for wind turbines, right?
That, um, if there’s a way to tax a wind turbine, we’re gonna try to do it. This is a unique way, uh, that happens in India where depending on if it’s permanent or movable, the tax rates are different. I, I guess that would apply to a lot of components inside a wind turbine too, Matthew, don’t you? Like the, the generator, the, the big heavy things, [00:25:00] gearbox, generator, blades, rotors, tower sections, would be taxed at a, a lesser rate.
Matthew Stead: I agree with the court case that it’s all movable and, uh, you can actually buy turbines on the secondhand market, can’t you? I mean, if I wanted to buy, yeah, whatever, whatever, I could buy one and, and put it up in my backyard if I had a bigger backyard. Um, so yeah, I vote for movable. I vote for lower taxes.
Yolanda Padron: The way that it would work a lot of times in the US is, I mean, it’s, you pay, the company itself pays a lot less than they would’ve over time, right? Just by pure, the, the regular kind of tax laws. Um, but the community, there’d be just direct donations to the community, so then they’d get, uh, like money would actually come into the community where the turbines were being built instead of just distributed around the state, which I mean, in a state as big as Texas, it gets, um, but easier for that c- um, that county to get a lot more, uh, funding than they would typically get if it was [00:26:00] through a big enough area.
Um, but yeah, no, I agr- I completely agree with you guys that, that this should be a movable good. I mean, how many times have we seen, uh, even just a blade, um, that it looks like it’s, uh, just a, a failed blade that they have to go in and replace, and then they take it out, fix it, and then just bring it back to the same site or take it to another site across the country.
And, and to that point, like if you were to h- judge it as something that’s immovable, would then any blade replacement just not be taxed? Because then it’s, you’re moving that one component and two, but it’s essentially the same turbine. Like, I don’t know how that all would make sense.
Allen Hall: I think the Uptime Supreme Court agrees with the Indian Supreme Court that wind turbines are movable, and that’s good.

Vermont and Florida: A Key Difference
Can’t swear that the story here is authentic, but it sure rings true.
Vermont is a somewhat quirky state, but it protects its citizens very well. FWIW, this is where I want MY tax dollars going too.
Florida is a deeply red state that, true to form, wants as much ignorance as it can possibly produce. Educated people aren’t voting for people like Ron Desantis.
