Did you know you could increase your solar panel’s efficiency without spending even a dollar?

Installing solar panels is a smart investment. It provides clean, renewable energy, lower power bills, and a reduced carbon footprint. But if you want your panels to keep performing at their best, there’s one thing you can’t skip: cleaning.

Researchers found that cleaning your solar panels could increase their efficiency by 15% to 20%!

Cleaning your rooftop PV will significantly boost your energy production and let you enjoy the power of the sun, maximizing your panel’s abilities. The best part is you can do it by yourself!

If you opt to have your solar panels cleaned by professionals, it will certainly save you the time and effort of doing it yourself. However, this task is significantly more straightforward, so hiring professionals isn’t always necessary.

Want more details on how to clean solar panels on a roof?

This DIY guide will walk you through everything you need to know about cleaning and maintaining your solar panels safely, efficiently, and effectively, all by yourself.

So, let’s get started!

In this blog post:

Why Do We Need to Clean Solar Panels?

Yes, in Australia’s diverse climate, we must clean solar panels periodically to maintain efficiency and energy output.

Dust, dirt, bird droppings, leaves, pollution and salt, especially in coastal or rural areas, can easily accumulate on the panels, blocking sunlight and reducing their performance.

Therefore, in Australia’s dry weather and frequent dust storms in some regions, regular cleaning helps ensure that solar panels operate at peak efficiency, maximizing return on investment and supporting consistent renewable energy generation.

So, if your solar panels are losing power silently, besides several other causes, dust could be one of the reasons for low efficiency and energy production.

Are Your Panels Dirty? | 6 Signs Your Solar Panels Need Cleaning

While solar panels typically require little to zero maintenance, there are certain warning signs that indicate they need cleaning. Ignoring these signs can lead to reduced efficiency and even early panel failure.

Here we’ve jotted down 6 common signs that can hamper your solar panel in Australia:

Reduced Energy Production
If you notice a drop in your solar system’s energy output despite sunny weather, it could indicate that dirt, dust, or debris is blocking sunlight from reaching the panels.
Visible Dirt and Debris
While standing on the ground, you can see grime or bird droppings on the panels. Therefore, look for visible dust particles, dirt, leaves, or other debris on the solar panels.
Stains and Discoloration
Any discoloration or stains on the solar panels, especially after a period of rain or heavy pollution, might clearly indicate that it’s time to clean them.
Increased Insect or Pest Activity
An increase in insects or pests around your solar panels means they are attracted to the accumulated dirt, pollen, or other organic matter on the panels.
Panels Installed at a Flat or Low Angle
Solar panel mounting styles can significantly affect their efficiency. For example, panels installed with minimal tilt may not be effectively cleaned by rainfall and require more frequent cleaning.
Monitoring Your System’s Output
If you have a monitoring system for your solar panels, you can track their performance and look for any signs of reduced energy output that may indicate a need for cleaning.

DIY Solar Panel Cleaning: Must-Have Tools & Safety Tips!

Many homeowners in Australia prefer DIY solar panel cleaning over professional help. But if you are planning to tackle the task yourself, you might need some essential tools and safety precautions for a successful DIY clean-up!

So, here is the equipment checklist for DIY solar panel cleaning:

Soft brush or squeegee with a long extendable handle

Garden hose with spray nozzle

A bucket with lukewarm water

Mild, non-abrasive soap

Microfiber cloth or soft sponge

Safety gear: harness, ladder, rubber-soled shoes

However, even though they are optional, you can use a leaf blower for light dirt and debris and deionized water for the spotless rinse.

Safety First! Read This Before You Climb

Before choosing a self-cleaning method for your solar panel, think twice. Why?

Well, initially, the roof may seem harmless, just a few short steps above the ground, but a single misstep can become a deadly drop.

One slip, one moment of distraction, and your world could change forever!

Roofs are deceptive, offering a false sense of safety and security. That’s why you must wear a safety harness. Remember, cleaning solar panels involves working at heights, so don’t take shortcuts on safety.

You should also consider the following precautions and safety measures:

Check the weather conditions: For cleaning solar panels, avoid windy, rainy, or especially hot days, as solar panels get hot in the sun.

Turn off the system: Before cleaning, check your inverter or manufacturer guidelines on how to shut off your solar setup safely.

Use a strong, stable ladder: Even if you anchor your ladder properly, have someone spot you if possible. Double-check that somebody is there to assist you in case of an emergency.

Use a harness or roof anchor: If you’re not experienced with roof work, consider hiring a professional to help with any of your solar needs.

Step-by-Step Guide to Cleaning Solar Panels Safely on Your Roof

Cleaning your solar panels is a simple but important task, and it should always start with safety. From ensuring safety concerns to using the right tools and proper care, every solar panel cleaning follows a stepwise process.

Once you’re on the roof, inspect the panels to see what needs cleaning: dirt, dust, or bird droppings.

So, let’s break down the solar panel cleaning process into easy steps!

Step 1: Shut Down the Entire System

Some may argue that it is not necessary to shut off the entire system, but it’s better to be safe.

However, the safest course of action is to switch off the entire system, which requires isolating the panels for the time being.

This will ultimately prevent even the small chances of a short circuit, which could otherwise lead to a house fire.

Step 2: Fasten Your Safety Harness

Please make sure you are safe when you go up the roof. It is an essential step in the process. You can also wear helmets, gloves or glasses to protect yourself from the heat burns during summer cleaning.

Even though it’s residential solar, it’s of the utmost importance that you ensure your safety first.

Step 3: Choose a Cooler Day or Early Morning

As you might already know, solar panels have a layer of glass protecting them from dirt, grime, scratches, etc.

A hot sunny day may make the glass layer very hot to the point that a splash of colder water could crack it.

Also, a scorching hot day is not ideal as you will be on the roof, closer to the sun.

Step 4: Start by Brushing Off Loose Dust & Debris

Use a soft-bristled broom, dry mop, or leaf blower to remove leaves, pollen, and loose dirt. This reduces the risk of scratching the surface when wet.

Step 5: Rinse with Lukewarm Water

Use a garden hose to gently spray the panels from the ground if possible. This helps remove dust and cools the surface before scrubbing with cleaning agents.

Here’s a pro tip!

Try to clean the panels in the early morning or late afternoon. Because at that time, the panels remain cooler, so water will not evaporate too fast.

Step 6: Use a Soft Bristle Brush

Gently scrub with a soft bristle brush to loosen up the dirt and spray it down with water. Do not use too much pressure while scrubbing; remember that solar panels are sensitive.

There are many types of brushes on the market that are created meticulously for cleaning solar panels.

Some brushes have rotating heads with an integrated water supply channel, and some are just plain brushes. You can choose any brush; just make sure they have soft bristles.

Step 7: Scrub Gently with Soapy Water or Mild Cleaning Agent

Using a cleaning agent during the cleaning process is not always necessary. You can use or skip them entirely, depending on how dirty your panels are.

Mostly only the brush and water seem sufficient, but in some cases, a cleaning agent is required.

Mix warm water with a few drops of mild dish soap in a bucket. Dip your microfiber cloth, sponge, or soft brush in the water and gently clean the surface.

Do not scrub hard or use any scratchy material; solar panels have a protective coating that can be damaged.

Step 8: Rinse and Dry the Panel

Rinse the panels again with plain water. If you want a flawless finish, use deionized water. Otherwise, let them air dry or use a soft squeegee to wipe off excess water.

And that is how it is done!

How Often Should You Clean Solar Panels in Australia?

Well, the answer to this question depends on many external factors, such as where you are located, at which angle you have your solar panels mounted, the positioning of your house, how often it rains in your area, etc.

However, here you have a general guideline for better insights:

Surrounding Environment	Cleaning Frequency
Urban, Smoggy Area with more pollution	Every 3 to 4 months
An area rich in plants, trees, birds and wildlife.	Every 2 to 3 months
A rural area with frequent rainfall	Twice a year
Desert or Dusty area	Every Month

Does Rain Really Clean Solar Panels? Find out!

Many people assume that rainwater alone can completely clean solar panels. While it’s true that rain can rinse off loose dust and dirt, it doesn’t remove tougher residues like baked-on bird droppings, pollution buildup, or sticky pollen.

However, in regions with frequent rain or storms, panels may stay cleaner for longer, but inspecting them a few times a year is still wise to ensure they work efficiently.

Common Mistakes to Avoid While Cleaning Solar Panels

Even solar experts and experienced users can make simple yet costly mistakes while cleaning solar panels.

But with proper knowledge and understanding, what to avoid can help protect your panels and maintain their efficiency.

Here are some common solar panel cleaning errors to watch out for:

Using harsh chemical materials can degrade your panels and void warranties.

Scrubbing with rough tools causes microcracks and scratches, reducing light absorption and the panel’s efficiency.

Cleaning panels on a scorching summer day while the panels are hot can crack the glass due to rapid cooling.

Walking on panels must be avoided. They’re not designed to hold your weight and can crack at any time.

Forgetting to shut down the system can cause unexpected short circuits, as water and electricity are not a good mix. So be aware of it!

So, avoid these common problems of solar panels while cleaning and ensure a long-lasting solar experience.

Additional Tips for Long-Term Solar Panel Care

A few proactive steps can make a big difference in minimizing cleaning needs and ensuring your solar panels continue performing at their best.

For example, installing mesh nets helps prevent birds or rodents from nesting underneath the panels, which can cause damage over time.

Moreover, trimming overhanging branches periodically not only reduces shade that may block sunlight but also limits the amount of debris that falls onto the panels.

You can also:

Monitor performance regularly to catch problems early.

Invest in a cleaning kit with extendable handles and soft brushes.

Keep the log for each cleaning with a photo while power checking to track efficiency.

In hot climates, ensure panels have adequate airflow to reduce overheating and damage.

In snowy areas, clear heavy snow carefully to avoid long-term shading.

Ensure your insurance covers all solar panel damage.

Know what your manufacturer and installers provide in detail. Solar panel warranties typically cover 20–25 years.

ACORE Statement on Treasury’s Safe Harbor Guidance

August 15, 2025

Statement from American Council on Renewable Energy (ACORE) President and CEO Ray Long on Treasury’s Safe Harbor Guidance:

“The American Council on Renewable Energy (ACORE) is deeply concerned that today’s Treasury guidance on the long-standing ‘beginning of construction’ safe harbor significantly undermines its proven effectiveness, is inconsistent with the law, and creates unnecessary uncertainty for renewable energy development in the United States.

“For over a decade, the safe harbor provisions have served as clear, accountable rules of the road – helping to reduce compliance burdens, foster private investment, and ensure taxpayer protections. These guardrails have been integral to delivering affordable, reliable American clean energy while maintaining transparency and adherence to the rule of law. This was recognized in the One Big Beautiful Act, which codified the safe harbor rules, now changed by this action.

“We need to build more power generation now, and that includes renewable energy. The U.S. will need roughly 118 gigawatts (the equivalent of 12 New York Cities) of new power generation in the next four years to prevent price spikes and potential shortages. Only a limited set of technologies – solar, wind, batteries, and some natural gas – can be built at that scale in that timeframe.”

Should I Get a Solar Battery Storage System?

Published

August 15, 2025

Alice Rush

Frequent power outages, unreliable grid connection, sky-high electricity bills, and to top it off, your solar panels are exporting excess energy back to the grid, for a very low feed-in-tariff.

Do all these scenarios sound familiar? Your answer might be yes!

These challenges have become increasingly common across Australia, encouraging more and more homeowners to consider solar battery storage systems.

Why? Because they want to take control of their energy, store surplus solar power, and reduce reliance on the grid.

But then again, people often get perplexed, and their biggest question remains: Should I get a Solar Battery Storage System in Australia?

Well, the answer can be yes in many cases, such as a battery can offer energy independence, ensure better bill savings, and provide peace of mind during unexpected power outages, but it’s not a one-size-fits-all solution.

There are circumstances where a battery may not be necessary or even cost-effective.

In this guide, we’ll break down when it makes sense and all the pros and cons you need to know before making the investment.

In this blog post:

Why You Need Battery Storage Now?

According to data, Australia has surpassed 3.9 million rooftop solar installations, generating more than 37 GW of PV capacity, which is about 20% of electricity in the National Electricity Market in 2024 and early 2025.

Undoubtedly, the country’s strong renewable energy targets, sustainability goals, and the clean‑energy revolution have brought solar power affordability, but the next step in self‑reliance is battery storage.

Data from The Guardian says that 1 in 5 new solar installs in 2025 now includes a home battery, versus 1 in 20 just a few years ago, representing a significant leap in adoption.

Moreover, the recent launch of the Cheaper Home Batteries program has driven this uptake even further, with over 11,500 battery units installed in just the first three weeks from July 1, and around 1,000 installations per day.

Overall, the Australian energy market is evolving rapidly. Average household battery size has climbed to about 17 kWh from 10–12 kWh previously.

Hence, the experts are assuming that 10 GW of new battery capacity will be added over the next five years, competing with Australia’s current coal‑fired capacity.

What Am I Missing Out on Without Solar Batteries?

Honestly? You’re missing out on the best part of going solar.

Renewable sources of energy like solar, hydro, and wind make us feel empowered. For example, solar batteries lower your electricity bills, minimize grid dependency, and also help to reduce your carbon footprint.

But here’s the catch! Without battery storage, you’re only halfway there!

The true magic of solar power isn’t just in producing clean energy; it’s storing and using it efficiently.

A solar battery lets you store excess energy and use it when the sun goes down or the grid goes out. It’s the key to real energy independence. Therefore, ultimately, getting a battery is what makes your solar system truly yours.

Here’s a list of what you’re missing out on without a solar battery:

Energy Independence

Batteries help you to stay powered even during blackouts or grid failures. With energy storage, you don’t have to think of fuel price volatility and supply-demand disruption in the Australian energy market.

Maximized Savings

Adding a solar battery to your solar PV system allows you to use your own stored energy at night instead of repurchasing it at high rates. It also reduces grid pressure during peak hours, restoring grid stability.

Better Return on Investment ROI

Tired of Australian low feed-in-tariff rates?

Make full use of your solar system by storing excess power at a low price rather than exporting it. Solar panel and battery systems can be a powerful duo for Australian households.

Lower Carbon Footprint

Despite the steady growth in solar, wind, and hydro, fossil fuels still dominate the grid. Fossil fuels supplied approximately 64% of Australia’s total electricity generation, while coal alone accounted for around 45%.

These stats highlight why solar battery storage is so valuable. By storing surplus solar energy, homeowners can reduce their reliance on a grid that still runs on coal and gas.

Peace of Mind

Enjoy 24/7 uninterrupted power, no matter what’s happening outside.

Besides powering urban homes and businesses, batteries also provide reliable power backup for off-grid living at night when your solar panel can’t produce, ensuring peace of mind.

What Size Solar Battery Do I Need?

While choosing the battery size, it isn’t just about picking the biggest one you can afford; it’s about matching your household’s energy consumption pattern. There is no one-size battery that will make financial or functional sense for everyone.

Nevertheless, if you have an average family of four with no exceptional power demands, you may get by with a 10kWh to 12kWh battery bank as a ready-to-roll backup system.

Well, this is just an estimation, as we have no idea of your power needs, because selecting a battery is highly subjective to the household in question.

With that being said, you can get a good idea of how much power you use on average by analyzing your electric bill copy. Also, keeping track of which appliances you use the most and which ones require the most power will help you.

So, to figure out the ideal battery size for your home, you need to consider three most important things:

Your Daily Energy Usage

Check your electricity bill for your average daily consumption (in kWh). Most Australian homes use between 15 to 25 kWh per day.

Your Solar System Output

How much excess solar energy are you generating during the day? That’s the power you’ll store to use later rather than exporting.

Your Nighttime Power Usage

A battery is most useful at night or during grid outages. So, estimate how much power you typically use after sunset. However, by using a battery, you can also get the freedom of living off the grid.

Sizing Up: The Ideal Home Battery for Aussies!

For small households and light usage, a 5 kWh battery will be suitable.

For average Australian households, adding a 10 kWh battery would be enough.

Large homes and high-energy users will need a 13 to 15 kWh system.

For full independence, off-grid living, or blackout protection, you may require a larger battery size of 20+ kWh.

How Much Do Solar Batteries Cost?

Previously, you would have to pay between $3000 and $3600 for the battery alone, plus the cost of installation, for every kWh of solar battery storage.

However, you can currently expect to pay between $1200 and $1400 for each kWh of solar battery storage. That is a price reduction of approximately 52%, and things will only get better from here.

Does that imply solar batteries are cheap now? Not really, but the cost is well justified by the pros of having a battery storage system.

Also, while paying for solar batteries, you have to consider many other factors like the type of battery, your solar panel system configurations and compatibility, brand, and installation partner.

These will significantly influence the price range of battery storage.

Is a Solar Battery Worth It | Pros and Cons at a Glance

It’s okay to feel a little overwhelmed while deciding to invest your hard-earned money in a battery.

So, here we’ve listed the pros and cons of having a solar battery to help you in the decision-making process.

Benefits of Solar Battery Storage

Solar batteries help you become self-sustaining.

You don’t have to care about power outages anymore

In the event of any natural disaster, you will still have a power source

Battery prices are dropping significantly as we speak

During peak hours, grid electricity prices increase due to high demand; you can avoid paying a high price and use your battery. It’s essentially free energy, as solar generates energy from the sun.

Reduced carbon footprint as the battery stores energy from a renewable source.

Advantages of battery for the grid and national energy system:

Batteries support Virtual Power Plants (VPPs). In 2025, consumers get financial bonuses (AUD 250‑400) for joining, plus grid benefits via distributed dispatchable power.

Grid‑scale batteries like Victoria Big Battery or Hornsdale Power Reserve are increasing system resilience by storing large amounts of renewable energy and reducing blackout risk.

Drawbacks of Solar Battery Storage

One of the biggest barriers is that solar batteries have a high upfront cost, which makes installation harder for residents.

Home batteries require physical space, proper ventilation, and can’t always be placed just anywhere, especially in smaller homes or apartments.

Most batteries, like lithium-ion batteries, last 5 to 15 years, meaning they may need replacement during your solar system’s lifetime.

While many systems are low-maintenance, some may require software updates, monitoring, or even professional servicing over time.

Battery production involves mining and processing materials like lithium or lead, which raise environmental and ethical concerns.

Should You Buy a Solar Battery?: Here’s the Final Call!

You should consider buying a solar battery if several key factors align with your situation.

First, it’s a strong financial move if you live in a state where federal and state incentives can significantly reduce the upfront cost. This can make the investment far more affordable.

A solar battery can be especially worthwhile if you value having backup power during outages, lowering your electricity bills, and gaining a measure of energy independence from the grid.

Additionally, you should be comfortable with taking a few extra steps to get the most value out of your system, such as joining a virtual power plant (VPP), which allows your battery to participate in grid services in exchange for modest returns.

Finally, it’s worth noting that rebates decline annually, and early adopters get the most value.

Takeaway Thoughts

Installing a solar battery in Australia in mid‑2025 offers substantial financial, environmental, and energy‑security benefits, especially if you qualify for multiple subsidies and have good solar capacity.

With rebates shrinking after 2025 and demand surging, early movers stand to benefit most.

By helping balance the grid and reduce dependence on fossil fuels, home battery adoption contributes significantly to Australia’s national goals of 82% renewable energy by 2030.

It’s not just about savings; it’s about being part of a smarter, cleaner, more resilient electricity future for Australia.

I just spoke with a guy in the wine industry, and I asked him how, if at all, climate change is affecting what we does.

From his perspective, it’s the horrific wildfires whose smoke imbues (or “taints”) the grapes with an unpleasant flavor that needs to be modified, normally by creative methods of blending.
