In 2010, Australia experienced a surge in solar battery installations nationwide. Since then, approximately 3 million homes have benefited from the advantages of rooftop solar, including lower electricity bills compared to those with only a grid connection.  

To paint a clearer picture, it is estimated that in NSW, generating 1 kilowatt of energy with solar panels saves approximately $400 per year.

However, batteries for solar systems are by no means a small investment, so the question remains: are solar batteries worth it in 2025 as an Australian homeowner? We will find out soon enough. But first, let’s get to know some basics about solar batteries.  

Types of Solar Batteries

Solar batteries, also known as solar energy storage systems, play a crucial role in solar power setups by storing surplus energy generated during sunny periods for later use, such as at night or on overcast days. 

These batteries come in various types, each with distinct characteristics and advantages. 

Lead-acid batteries

Lead-acid batteries, including Flooded Lead-Acid (FLA) and Valve-Regulated Lead-Acid (VRLA) options, offer durability and cost-effectiveness, with VRLA batteries like Absorbent Glass Mat (AGM) and Gel batteries being maintenance-free. 

Lithium-ion batteries

Lithium-ion batteries, such as Lithium Iron Phosphate (LiFePO4), Lithium Nickel Cobalt Manganese Oxide (NMC), and Lithium Nickel Cobalt Aluminium Oxide (NCA), provide high energy density, extended lifespan, and enhanced safety. 

Flow Batteries

Flow Batteries, represented by Vanadium Flow Batteries, offer a liquid electrolyte and are known for their extended cycle life and scalable capacity. 

Saltwater Batteries

Saltwater Batteries, specifically Sodium-Ion Batteries, are environmentally friendly and potentially cost-effective. Nickel-iron or Edison batteries are durable but have lower energy density. Hybrid Batteries combine different technologies for optimised performance. 

Choosing the correct solar battery involves considering factors such as cost, space, maintenance, and intended application, while ongoing advancements in battery technology may introduce newer options.

Reasons Why You Should Get Solar Batteries

Solar battery prices are not low, but the payback period decreases with the daily price hike of energy in Australia. Given the current economic environment, energy prices are expected to continue rising. 

According to the Australian Energy Market Operator (AEMO), the wholesale cost of power in the National Electricity Market (NEM) jumped by 141 per cent in the first three months of 2022 compared to the same quarter last year. 

That said, storing the surplus of energy generated by your solar panels sounds like a sound investment, doesn’t it?  

Here are some more reasons-  

End of Net Metering in Australia  

Net metering is a system that allows you to send the excess power generated by your solar panels to the grid and get a portion of the exact amount back on demand. 

People were utilising the grid practically as a storage facility when the net metering system was still in place, but that luxury is no longer available. 

Net metering was available in the Northern Territory until April 2020; however, the benefit is no longer available for solar systems constructed after that date. 

Essentially, with the end of net metering, you no longer have the freedom to obtain a one-to-one net metering service (i.e., a kW received per kW given).  

That doesn’t mean you don’t have other means to store energy in the grid; you do. However, that is not as beneficial as net metering and certainly not as profitable as having your solar battery.  

Solar panels can generate a varying amount of energy throughout the day, as the sun’s brightness changes from sunrise to sunset. 

The maximum amount of electricity generated by the solar panels is between 12:00 p.m. and 3:00 p.m. An average Australian household consumes relatively little electricity during that time, as most are at work.   

Studies have shown that, with the surge in electric prices off the grid, it makes more financial sense to store excess energy in the grid; instead, having a solar battery and using it on demand will be much more profitable in 2025. 

Electricity Prices are Higher at Night  

As a storage unit does require a significant investment, you decided to export the surplus of electricity to the grid. 

But, keeping in mind that an average household requires more energy at night than in the day, you will be paying more to buy back that amount of electricity you exported at night.  

So, it’s evident that storing the surplus in a solar battery makes more sense than repurchasing it at a higher electricity cost.  

Grid Outages  

There are times when people experience power outages. It can occur during a scheduled grid check-up, a devastating storm, or for any other reason. It’s more common than you would think. In those cases, a solar battery can be your solution.  

We are positive you would prefer to avoid coming home to a fridge full of rotten food. To have an uninterrupted supply of energy that you have all the control over, having a battery storage unit makes perfect sense.  

Yes, of course, you could opt for a backup generator, but they are noisy, and it defeats the purpose of having solar installed on your rooftop in the first place. It runs on diesel, a non-renewable energy source contributing to carbon emissions.   

Are Solar Batteries Worth It?

It makes sense for a large energy user to opt for solar batteries. They are worth the price, and here is why-  

The cost of solar batteries is coming down significantly as we speak. For instance, back in 2020, a 6 kW solar battery cost about $10,000, which now is about $7,700 

It is the only way to go for those who live off the grid  

Without the benefit of Fit, having one’s storage system saves on power bills and provides even more complete control over your energy consumption  

Power backup for days in the event of a power outage, and with the addition of solar panels, you can eliminate reliance on the grid.   

Solar and Battery Package Price in Australia: How Much Do Solar Batteries Cost?

Determining the actual price of solar batteries can be challenging due to the numerous variables involved. For example, it will depend on your power needs, including whether you have any power-hungry appliances, household size, and geographic location. 

Depending on these variables, you can determine the size of the storage unit you require. Thus, that’s how the cost of solar batteries is estimated.  

But to give you a rough idea, the price of a kWh of residential solar battery storage can hover over the $1000 mark. 

These include the cost of installation and GST. Remember that the battery brand and all the other factors mentioned ultimately matter, and prices vary depending on these factors.  

10kw Solar Battery Price

As of 2025, in Sydney, NSW, the current cost of a 10 kW solar battery paired with a 6.6 kW solar panel system ranges from $13,000 to $13,500.

This price includes two 5.1 kWh modules integrated with a 6.6 kW solar system. The potential payback time for this system can be as short as 4 years. 

The Tesla Powerwall, which has a storage capacity of 13.5 kWh, costs approximately $1,150 per kilowatt-hour. 

When considering the broader market, solar batteries without the solar component typically fall from $900 to $1,200 per kilowatt-hour. The specific pricing varies based on the brand and model.

6 kW Solar Battery Cost

The solar battery storage cost refers to the amount you pay for each unit of electricity it can store, typically measured in dollars per kilowatt-hour ($/kWh). 

Typically, these batteries cost between $900 and $2,000 per kilowatt-hour. If you opt for a solar setup with a 10.2-kilowatt-hour battery and a 6.64-kilowatt solar system, the cost is approximately $13000.

If you only want the battery, without the solar system, a standalone solar battery can cost $990 per kilowatt-hour. It includes a particular device called a hybrid inverter that connects the battery to the solar system.

For a specific type of battery called the Tesla Powerwall, which has a 13.5 kilowatt-hour capacity and comes with its own inverter, the price is $1200 per kilowatt-hour.

Another type of battery, the Sungrow 9.6 kilowatt-hour solar battery, is priced at $1227 per kilowatt-hour. This cost includes a 5-kilowatt hybrid inverter.

Suppose you’re considering a solar panel system with a 6-kilowatt capacity and a battery with a 16.6-kilowatt-hour capacity. In that case, the total cost for installing this combined system can range from approximately $19,935 to an average of $25,235. 

The exact price depends on the type and quality of the system you choose. For more details, check out the cost of a 6kW solar battery in Australia.

Solar battery ROI

The return on investment (ROI) for solar batteries in Australia is influenced by several factors, including the system’s initial cost, local electricity rates, solar generation capacity, and available government incentives or rebates. 

Key considerations include the upfront expenses, which encompass the battery, inverters, installation, and related components. 

The cost of grid electricity in your area is pivotal, with higher rates potentially leading to faster returns, as stored solar energy use during peak periods saves on electricity bills. 

Solar panel efficiency, battery performance, and lifespan also impact long-term returns. Government incentives, rebates, and electricity consumption patterns, particularly during peak demand periods, significantly contribute to the overall return on investment (ROI). 

Monitoring technological advancements is crucial for evaluating the long-term economic viability of solar battery systems. 

Seeking professional analysis and staying informed about industry trends and policy changes are advisable for making well-informed investment decisions in Australia.

How To Choose Solar Batteries?

State Rebates for Solar Batteries

State rebates for solar batteries vary across Australia. States like South Australia, Victoria, and Queensland offer specific incentives and rebates for solar batteries. 

However, rebate programs and amounts are subject to change, so it’s essential to check the latest information from your state government or relevant authorities for the most up-to-date details on solar battery rebates.

Solar Battery FAQs

When choosing solar batteries in Australia, consider your energy needs, capacity, performance, compatibility with your solar system, warranty, and cost. Assess the battery’s kilowatt-hours (kWh) storage capacity to match your daily usage.

Look for reliable brands and models with proven performance and longer lifespans. Ensure compatibility with your existing solar system, and check for government incentives or rebates. Compare the cost per kilowatt-hour and warranty terms to determine the best option. 

Consider factors like installation requirements and whether the battery supports backup power. Seek professional advice to tailor your choice to specific needs and conditions.

What Size Solar Battery Do I Need to Power a House?

The size of the solar battery needed to power a house in Australia depends on various factors, including your energy consumption, the size of your solar panel system, and your specific energy needs. 

On average, a medium-sized household might require a solar battery with a capacity ranging from 5 kWh to 20 kWh. 

To determine the appropriate size, consider your daily electricity usage, the sunlight your location receives, and whether you want the battery to provide backup power during outages. 

It’s advisable to consult with a solar energy professional to assess your specific requirements and design a system that meets your energy goals.

Is a Solar Battery Worth it?

Deciding whether to invest in home battery storage depends on various factors. Your energy consumption, goals, and dependence on the grid play crucial roles. 

A battery could be valuable if you experience frequent power outages or seek backup power. Explore the government incentives, rebates, and electricity rates in your area to assess the financial benefits available to you. 

A well-designed solar panel system can enhance the potential benefits of integrating a battery. Consider the environmental impact, battery lifespan, and technological trends. To make an informed decision, consult with solar professionals like Cyanergy

North Carolina needs more certainty before committing to an expensive new gas plant

Published

on

Despite massive uncertainty across the economy, Duke Energy is plowing ahead with its plan to build new fossil gas-fired power plants to serve data center, manufacturing, and other large customer load that may not even show up. Duke has asked the NC Utilities Commission for permission to build a combined-cycle (CC) gas plant in Person County, North Carolina, at the site of Duke’s Roxboro coal plant.

SACE has argued against the need for this gas power plant in the Certificate of Public Need and Necessity (CPCN) docket, submitting testimony to the Commission on Monday, June 9, 2025. Here’s a summary of that testimony (prepared by Synapse Energy Economics, Inc.), which explains what this all means for Duke’s billpayers, and how Duke can make changes within its control to protect customers and reduce pollution. These recommendations include:

  • Not approving this new gas power plant because the risks that it will increase bills are too high. Instead, Duke should improve the processes that are holding back lower-cost renewables and storage, then use renewables and storage to meet new load.
  • Instead of approving this specific gas plant, the Commission should order Duke to use an all-source procurement process to determine a portfolio of flexible assets that can meet the utility’s needs based on real-world costs.
  • In the event the Commission approves this gas plant, it should protect customers from high bills due to volatile gas prices by instituting a fuel cost sharing mechanism for the fuel costs spent to run this plant.

Duke Doesn’t Need this Risky Gas Power Plant

Duke’s claim that it needs this fossil gas power plant is based on outdated analysis. In this CPCN docket, Duke relies on its 2023 Carbon Plan Integrated Resource Plan (CPIRP) modeling and the CPIRP supplemental update and analysis filed in January 2024. The world has changed dramatically since then, and it is important that the Commission review the latest information before approving expenditures that will impact customer bills for decades.

Duke’s load forecast – once based on steady, predictable growth – is now subject to significant uncertainty as 1) data center developers look around the country for the best deal and the fastest interconnection to the grid and 2) manufacturers announce projects and then pull back as political uncertainty changes the economics of those projects. Under Duke’s current rate structure, prospective companies and site developers do not need to commit much money to become part of Duke’s load forecast. They have very little “skin in the game,” and Duke currently does not have policies in place to change this. If the Commission allows Duke to build an expensive fossil gas plant for load that doesn’t materialize, Duke’s remaining customers will be on the hook to pay for it.

Duke’s own load forecast updates since 2023 show that there are wild swings in its predictions. In the Spring of 2023, Duke anticipated 8 new large load projects during its 10-year planning forecast period, requiring an average of 169 MW each. Then for Fall 2023 (the supplemental update filed in January 2024), Duke anticipated 35 projects requiring an average of 111 MW each. In Summer 2024, Duke changed its forecast again, projecting 39 projects requiring an average of only 103 MW. And in May 2025, Duke filed an update showing a reduction in the number of projects back down to 35 but a dramatic increase in average need – back up to 169 MW. Duke’s forecasts will continue to show swings up and down – both in the number of projects and megawatts – until Duke has policies in place that require more commitment from the companies that knock on its door requesting service. Duke also has not published information regarding the location of these loads – the latest forecast applies to all of Duke Energy in both North and South Carolina.

It is also important to know that that this gas plant isn’t needed to meet growing load from existing customers or to replace retiring coal plants (according to Duke’s own testimony). This gas plant is being justified by new manufacturing and data centers claiming they will be operating somewhere in Duke Energy Progress or Duke Energy Carolinas territory in North or South Carolina.

Even if the load shows up, this plant won’t be needed for long

Even Duke admits that it doesn’t “need” this fossil gas power plant for very long. These kinds of power plants, combined-cycle plants, are typically used about 80% of the time, i.e. they are “baseload” power plants. But even absent federal carbon regulations, Duke expects this power plant’s usage to decline significantly throughout its 35-year lifetime (from 80% in 2030 decreasing to 46% by 2040 and only 13% by 2050 onwards). As cheaper renewables and storage with zero fuel costs are brought online, they will displace this plant. Duke is proposing to build a giant power plant that will very quickly run less and less – but Duke’s customers will continue to pay for it until 2065—15 years past a state law requiring Duke’s generation fleet to be carbon neutral. This represents a significant change in how power plants are built and run, and this is not in the best interest of Duke’s billpayers. To add insult to injury, Duke hasn’t even procured all of the equipment needed to build this plant, so the costs could skyrocket even more than they already have since last year’s carbon plan proceeding.

Renewables are flexible, would protect customers, and would reduce pollution

Duke’s model only chose a gas plant to meet this capacity need because of limits Duke imposed on the model. Duke claims it cannot interconnect renewables and storage fast enough to meet this capacity need, but the reasons it cannot interconnect those resources faster are all within Duke’s control. As Synapse recommends, Duke needs to update its processes that are holding back renewables and storage from serving customers with low-cost and low-risk resources. These processes include interconnection and transmission planning.

SACE has been advocating for improvements to these processes for years, and Duke has made changes to both its interconnection process and transmission planning. Duke was one of the first utilities in the Southeast to implement cluster studies in its interconnection process, and it is in the midst of the first scenario-based transmission planning exercise in the region. But is there evidence that these updates have helped if Duke continues to limit solar and storage in its future resource modeling? Given the much quicker interconnection process recently demonstrated in Texas, this raises the question of how hard Duke is really trying to streamline renewables interconnection.

Modular, flexible resources such as wind, solar, and energy storage can be adjusted in quantity based on market conditions. As our testimony from Synapse states, “This modularity, combined with the fact that solar and wind have zero exposure to fuel price volatility once they are constructed, makes these resources particularly valuable in the face of trade tariff uncertainty.”

The bottom line is that the Commission needs a lot more certainty about load growth and costs before committing Duke’s billpayers to any type of large fossil gas power plant. We simply do not have that now.

Ultimate Guide To Understanding Every Type Of Solar Panel

Published

on

Are you thinking of switching to solar but feeling overwhelmed by the wide range of panel options available in the market? 

You’re not alone, as many others feel the same way. 

In a sun-drenched country like Australia, where electricity prices seem to climb every year, more households are turning to solar as a smart, sustainable solution.  

The reason for this energy transition is apparent: harnessing clean, renewable energy gives you energy freedom, saves you costs on electricity bills, and reduces your reliance on fossil fuels, lowering your carbon footprint.   

Moreover, solar panels are not only good for the planet; they’re an investment for your future!  

But with so many types of solar panels, how do you know which one is right for you? 

  • Which panels perform best in Australia’s diverse climate?
  • What type suits your roof, your budget, and your energy needs?
  • And most importantly, are they really worth the cost? 

Well, in this comprehensive guide, we’ll explain the above questions and everything you need to know about solar panels in Australia.  

From solar panel types to benefits and efficiencies, this ultimate guide on all types of solar panels in Australia will help you find the most suitable panels for your home and financial needs. 

So, tag along to learn more details!  

What Are Solar Panels? | Breaking Down the Power of the Sun!

Let’s begin by addressing a very basic question: What is a solar panel, and how does it work? 

A solar panel is a device that converts sunlight into electricity using photovoltaic (PV) cells. Instead of burning fossil fuel, these different types of solar panels generate clean, renewable energy with Australia’s abundant sunlight.

How Solar Panels Work: A Simple Breakdown!

At the core of every solar panel, there is a set of photovoltaic (PV) cells. These cells are responsible for converting sunlight into usable electricity.  

When sunlight hits these cells, it excites electrons within the silicon-based material, creating an electric current. This current is then captured and converted into alternating current (AC) through an inverter, making it suitable for household or commercial use.  

However, solar panels cannot store energy for later use. Therefore, you might need to add battery storage to keep your home illuminated at night or during low-light hours. 

Are They Worth It for Australians?

Solar panels are generally a smart investment for most Australians due to the country’s high solar exposure, government incentives, and rising electricity costs.  

With abundant sunshine, households in most Australian cities can generate a significant portion of their electricity needs from solar. This energy switch can be a significant key to reducing power bills while enhancing grid stability. 

For example,  a 6.6 kW solar system can save households $1,000–$2,500 per year, depending on usage and feed-in tariffs. They can reduce your power bills by up to 70% 

Moreover, the federal Small-scale Renewable Energy Scheme (SRES), energy-saving schemes and various state rebates and incentives significantly reduce the upfront cost of solar systems.

So, with all these long-term savings, generous incentives, and positive environmental impact, solar panels offer a sustainable solution, making them a worthwhile financial and environmental investment for all.  

What Are the Most Popular Types of Solar Panels Available in Australia?

types of solar panels

Australia’s strong solar market offers various solar panel options tailored to different needs, budgets, and property types. Homeowners can access high-quality solar technologies from both local and international manufacturers, creating a global bond.  

However, instead of making a blind choice, it’s wise to understand the different types of panels, as each has different efficiency, durability, and cost advantages.  

So, before moving further, let’s have a glimpse at the most popular types of solar panels currently available in Australia:  

Monocrystalline Solar Panels: Premium Efficiency and Longevity

Monocrystalline solar panels are the most efficient type of solar panel. They are made from a single, pure crystal structure, which allows electrons to move more freely, resulting in higher efficiency.   

These panels are easily recognizable by their dark black color and rounded edges. While they are more than other types, their high efficiency and longevity make them a great investment. 

What are the Pros? 

  • High performance in low-light and high-temperature conditions. 
  • Sleek, modern look. 
  • Lower long-term cost per watt. 
  • Best for homeowners with limited roof space.  
  • Incredible longevity and efficiency.  

Talking about Cons: 

  • Monocrystalline panels are expensive. 
  • The manufacturing process results in silicon waste. 

Polycrystalline Solar Panels: Reliable and Cost-Effective

Polycrystalline solar panels are made from multiple crystal structures, which gives them a blue hue with a speckled look.  

They are less efficient than monocrystalline panels but are also less expensive. These panels are great for those with ample roof space and a tighter budget.  

What are the Pros? 

  • More affordable than Monocrystalline panels. 
  • Leaves less waste during production. 
  • Offer decent performance for residential use. 
  • Easier manufacturing process.

Talking about Cons: 

  • Less efficient. 
  • Require more space than Monocrystalline panels. 
  • Lower the aesthetic appeal of homes. 

Thin-Film Solar Panels: Lightweight and Versatile

Thin-film solar panels are the most affordable but least efficient type, with energy efficiency ranging from 7% to 18%. They are made by layering photovoltaic materials onto a surface.  

These panels are flexible, lightweight, and ideal for industrial and commercial use in Australian landscapes. 

The types include: 

  • Cadmium Telluride (CdTe) Panels 

Cadmium telluride is the most common thin-film panel, constituting about 5% of solar panel sales. These panels can achieve an efficiency rating of 9% to 15%. 

They are made from cheaper, toxic materials such as cadmium telluride and cadmium sulphide, which can pose environmental and health risks. 

  • Amorphous Silicon (A-Si) Panels 

Amorphous silicon panels use a different technology that makes them very flexible. Instead of using crystalline silicon wafers, these panels use a thin silicon strip with a rubber-like texture. 

These panels are incredibly lightweight, versatile, non-toxic, and cheap, but have a low efficiency rating of about 7%. 

  • Copper Indium Gallium Selenide (CIGS) Panels 

CIGS panels are the most efficient thin-film panels available. They are composed of copper, gallium, indium, and selenide layers placed on a base of steel, glass, plastic, and other materials. 

These panels can be installed where standard panels cannot fit. They have a high enough efficiency rating of 12% to 15%.  

Bifacial Solar Panel: Power from Every Angle!

Bifacial solar panels can generate power from both sides, capturing sunlight that hits the front of the panel and light that reflects onto the back. It’s like double the sides, double the Power! 

This can increase energy production by up to 30%. They are ideal for ground-mounted solar systems or buildings with reflective roofing.  

Concentrated PV Cell (CVP)

Concentrated PV cells are the most efficient type of solar panel available today. They use lenses or curved mirrors to focus sunlight onto a small area of high-efficiency solar cells.   

However, they require direct sunlight and a cooling system to function effectively. They are more suitable for large-scale commercial projects in sunny locations.   

Solar Panel Types by Efficiency and Longevity: A Detailed Comparison

Type Efficiency Lifespan Perfect for
Monocrystalline 18–22% 25+ years Homeowners with limited roof space or those prioritizing efficiency and longevity.
Polycrystalline 15–17% 20–25 years Budget-conscious users with ample roof space.
Thin-Film 10–13% 10–20 years Large buildings, factories, and unconventional surfaces like car roofs or windows.

5 Factors to Look for While Installing a Solar Panel in Australia

Choosing the right panel is just half the job, where installation quality and system design play a huge role in overall performance. 

So, here we’ve listed what to consider before installing a solar panel on your property:

1. Sun Exposure and Roof Orientation

Proper sun exposure is a significant factor for maximizing energy production. In Australia, a north-facing roof typically captures the most sunlight.  

Also, ensure your roof is free of large trees, chimneys, or other shading.

2. Solar Panel Efficiency

Higher solar panel efficiency means more power, which ultimately leads to faster return on investment (ROI). This is especially important if your roof area is limited or you live in a rented property.

3. Durability and Warranty

Look for panels that offer 25-year performance warranties and 10–15-year product warranties.  

These warranties can provide long-term peace of mind and potentially save you significant repair or replacement costs.  

4. Installer Credentials

Once you decide to install solar, choose Clean Energy Council (CEC) accredited installers.  

They’ll help make sure your system follows Australian rules and let you know about rebate eligibility criteria.  

5. Proper Installation and Aftercare

Lastly, the installer will mount the solar panels on your roof and connect them to a solar inverter.  

After the installation, the system will need to be inspected by a certified electrician. Then, a monitoring app will track how much electricity your system produces and how much you use.

Some Other Hidden Factors That Might Impact Your Solar Setup!

While planning a solar installation, most people focus on the obvious elements like panel type, system size, and cost.  

However, beyond these core considerations, there are several lesser-known factors that can quietly influence the efficiency, longevity, and overall success of your solar setup.   

This includes: 

  • Hail Rating of the Panel 

This rating indicates how well solar panels can withstand hail impacts. Panels are typically tested by firing ice balls at them to simulate hail.  

A higher hail rating means better durability in hail-prone areas, reducing the risk of cracks and performance loss. Crystalline panels can handle hail hitting speeds up to 50 mph, while thin-film panels are thinner and less resistant. 

  • Temperature Tolerance of the Panel 

Solar panels become less efficient at high temperatures. Temperature tolerance, often measured as a temperature coefficient, tells you how much performance drops per degree above 25°C.  

Lower coefficients mean better performance in hot climates. So, here are the temperature coefficients for different panel types: 

    • Monocrystalline: -0.3% to -0.4% / °C  
    • Polycrystalline:  -0.4% to -0.5% / °C 
    • Thin-film: -0.2% to -0.3% / °C 
  • Fire Rating of the Solar Panel 

Solar panels and mounting systems must meet fire safety standards. The fire rating is usually classified in Class A, B, or C, reflecting the system’s resistance to fire spread and ignition.  

Class A is the most fire-resistant, which is crucial in wildfire-prone regions like Australia. 

  • Light-Induced Degradation (LID) 

LID (Light-Induced Degradation) is a common issue in crystalline solar panels, where they lose about 1–3% of their performance during the first few hours or days of sun exposure.  

It happens when sunlight reacts with tiny amounts of oxygen left in the silicon during manufacturing.  

This reaction slightly disrupts the silicon structure, reducing the panel’s efficiency. 

How to Choose the Right Solar Panels for Your Property?

Every home has different setups, so the solar panel installation process also varies from home to home. Here’s a stepwise checklist to help tailor the perfect setup: 

Step 1: Assess Your Energy Needs 

Before choosing solar panels, look at how much electricity your home uses. Check your electricity bills to calculate your average daily usage in kWh 

If you’re planning to expand or add things like an electric vehicle or a home addition, consider how that might increase your energy needs in the future. 

Step 2: Evaluate Roof Size and Position 

In Australia, your roof’s position and condition matter greatly for solar energy generation. Therefore, while installing the panel, you should consider: 

  • Roof orientation, as south-facing roofs typically capture the most sunlight.
  • Proper tilt and shading for minimal shading from trees, chimneys, or nearby buildings.
  • Larger roofs offer more installation space, while older roofs may need repairs, so check the roof size and condition first. 

However, if you have limited space, go for high-efficiency monocrystalline panels, and Polycrystalline might be a better value for plenty of space. 

Step 3: Set a Budget 

Solar Power System prices vary widely from place to place. But with our 440W Tier-1 Panels and 5kW Wi-Fi Inverter in a 6.6kW Solar Power System, you can enjoy the benefits of solar power without a hefty price tag. 

  • For 6.6 kW System: 

Original Price starts from $3,690.00 

Cyanergy’s VIC Offer Price starts from $890.00 

  • For 10.12kW System 

Original Price starts from $5,770.00 

Cyanergy’s VIC Offer Price starts from $2,970.00 

  • For 13kW System 

Original Price starts from $7,130.00 

Cyanergy’s VIC Offer Price starts from $4,330.00

Step 4: Find a Trustworthy Installer & Factor in Rebates 

Federal STC rebates and various state-based incentives can save you thousands off your upfront cost, so look for a certified, experienced installer who can help you claim them.

So, Which Solar Panel Type Should You Use?

Honestly, there is no specific answer to this question. The panel type and effectiveness depend on several factors, including your installation location, budget, and aesthetic preferences.  

However, here we’ve shared a quick guide based on different situations to make your purchase decision easier:  

Different Scenarios Recommended Type
Limited roof space or rental property Monocrystalline
Tight budget with big roof space Polycrystalline
Flexible portable solutions Thin film
Need long-term high output Monocrystalline
Off-grid or rural installations Thin-Film or Hybrid

Wind Turbine Monitoring: Fibersail’s Predictive Maintenance Could Save Operators Billions

Wind turbine blade failures represent the largest ongoing expenditures facing wind energy operators, with over $5-6 billion spent annually on unplanned repairs. What if wind turbine monitoring detected blade damage before it becomes catastrophic – and could give operators a clear strategy to prevent failure?

That’s what Fibersail, based in Portugal, with offices in the Netherlands, has developed with its innovative fiber optic sensing system.

Fibersail CEO Carlos Oliveira joined us to discuss why they developed this new turbine monitoring system, what they learned along the way, and how it’s working for wind farms around the world.

You can listen to the interview here or read the highlights below.

The Future of wind turbine Monitoring

As the wind industry continues to scale and turbines grow larger, the need for advanced monitoring systems has increased as well. Fibersail’s fiber optic technology represents a fundamental shift from reactive maintenance to predictive maintenance, potentially saving the industry billions while improving the reliability of renewable energy generation.

Wind Turbine Monitoring is a Billion-Dollar Problem

Most operators face the same stark reality: traditional monitoring systems simply aren’t equipped to handle today’s massive turbine blades. As Oliveira put it, “We are building bigger and bigger blades, using old technology. It does not work.”

Where turbines once showed problems after 5-8 years of operation, today’s operators routinely see major blade issues within the first year or two of operation—sometimes even during the warranty period. This dramatic change has led to some major companies recognizing billions in losses due to blade-related issues. It’s conceivable – realistic, even – that if this trend continues, it could put the entire wind industry at risk.

Why Go Beyond Traditional SCADA Systems?

Most wind turbines today rely on SCADA (Supervisory Control and Data Acquisition) systems for monitoring, but they weren’t designed to detect the structural issues that lead to blade failures. Fibersail’s fundamentally different approach brings advanced sensing technology directly to the blade structure.

The company’s fiber optic technology provides real-time data about blade behavior that simply isn’t available through conventional monitoring systems.

The Shape-Sensing Revolution

Fibersail’s innovation is its unique “shape sensing” technology. The concept originated from measuring sailboat sails and has evolved to monitor wind turbine blades—essentially treating each blade as a “rooted sail.”

Here’s how it works:

  • Fiber optic sensors are installed directly inside the blade, running from root to tip
  • The system monitors the blade’s shape in real-time, detecting minute changes that indicate structural issues
  • Dual validation occurs by monitoring both shape changes and frequency variations
  • All complexity is encapsulated in a robust system that field technicians can easily install

A Pragmatic Implementation Strategy

Ideally, a sensing system that is built into the blade would be an OEM integration, but Fibersail knew that would delay market entry, possibly for years, while operators and quite possibly the industry – ran out of money and out of business.

Rather than waiting for OEM integration, then, Fibersail began working directly with wind farm operators—the ones who face the immediate financial impact of blade failures.

“The owner-operators are the ones who have the problem to solve,” Oliveira explained. And by working directly with wind farming operations, Fibersail is better able to gather real-world data to prove how the sensing system saves blades, and money. The strategy is paying off.

The company is currently collecting field data from multiple installations, with promising early damage detection and damage propagation projects underway. This real-world validation is crucial, Oliveira emphasized, saying, “Nothing is as valued as the data from the field.”

From Data to Actionable Intelligence

Perhaps most importantly, the data Fibersail provides is not just graphs and charts, but actionable intelligence. Oliveira calls the solution “elegantly simple.” When the Fibersail system detects a problem or potential damage propagation, it sends an email alert to operators, allowing them to prioritize their limited maintenance resources effectively, and to focus on turbines that need immediate attention, while allowing others to wait for scheduled maintenance.

Blade Manufacturing: Variations Happen

Unfortunately, in working with wind farm operators, Fibersail has seen firsthand the frustrating reality of blade manufacturing variability. While blades are theoretically identical when they leave the factory, manufacturing tolerances mean each blade is slightly different. Add a few years of operation, repairs, and patches, and operators end up with what Oliveira colorfully describes as “Frankenstein turbines.”

This variability makes traditional numerical models inadequate for predicting real-world blade behavior – and it highlights the need for actual sensing technology.

Overcoming Installation Challenges

One of the biggest hurdles in the industry is navigating warranty restrictions and service agreements that can prevent operators from installing aftermarket monitoring systems. Fibersail positions itself as a solution provider for the entire industry, not just for the owners and operators, but also working with manufacturers and developers.

The company aims to create three-way partnerships between Fibersail, the customer, and the OEM when possible. The entities are more likely to work together when they see how the technology benefits all parties, by reducing costs and improving reliability – always a key to navigating warranty issues.

Oliveira noted that Fibersail understands its customers need to comply with strict cybersecurity requirements, which is simply a necessity in today’s complicated energy industry.

Tailored Solutions at Scale

Fibersail offers a modular product line that can be customized based on customer equipment, site conditions, and other operationall factors, including –

  • Basic load sensors for customers needing fundamental load data
  • Shape sensors for early damage detection
  • Hotspot sensors for comprehensive damage monitoring
  • Integrated systems combining multiple sensing technologies

Because of the company’s flexible offerings, customers can start with a basic monitoring system and add complexity as needed.

Expanding into Offshore

While Fibersail is currently focused on onshore installations, the company is expanding to offshore applications, with the first Fibersail offshore installation in the Netherlands planned for this summer. In the more challenging offshore environment, the company expects that the return on investment will be even greater.
