how long do solar panels last
Solar panels, usually photovoltaic or PV panels are designed to endure for more than 25 years. Many solar panels placed as early as the 1980s still operate at full capacity. Solar panels are not only very dependable but solar panel lifespan and durability have risen substantially over the past 20 years.

How Long Do Solar Panels Last – Solar Panel Lifespan

The industry standard for the productive lifetime of most solar panels is 25-30 years. On the other hand, a solar panel will not degrade after 25-30 years. Instead, solar panel degradation will occur, and it would be substantially lower than what the manufacturer predicted. It’s impossible to estimate the initial cost of a solar system without knowing how long your rooftop panels will generate adequate power. Your solar energy system will be able to balance your power consumption for decades, but you must be aware of industry projections and solar panel degradation rates.

Factors That Affect Solar Panel Degradation Rates

Due to the environment, solar panel degradation happens over time. Extreme weather conditions such as flooding, snow, ice, and high temperatures may lead to crystalline silicon hardening, frame damage, and cell contamination. Microcracks in the panel’s surface may be caused by hail, ice, dust, or sand and water can enter the solar panel if the seal is broken.

Cold temperature

In the winter, solar panels are also less likely to reach their peak temperature or power. Once their temperature rises above that peak temperature, the solar panel output goes down. Research has demonstrated that solar panels degrade and begin losing efficiency around 77ºF.

UV radiation

UV radiation accelerates the degradation of solar power devices, deteriorates polymeric encapsulates of modules, and possibly affects the antireflective coatings applied on solar cells.

Aging-related factors and chemical reactions

Solar panels age because of their constant exposure to the elements. Hardening of the crystalline silicon, corrosion of the frame, and cell contamination is all brought on by extreme weather conditions such as heavy rainfall, snowfall, ice, and hot temperatures. Microcracks on the panel’s surface may be caused by hail, dust, sand, and ice that can enter the panel if the seal is broken.

There is also the issue of shadowing, which limits the amount of light the panel can convert into electricity due to reactions in the semiconductor materials employed in the cells.

How to Make Your Solar Panels Last Longer

The quantity of sunlight that solar panels can absorb may be diminished by dust, grime, and bird droppings. Maintaining your solar panels at optimal efficiency to maximise energy production requires a yearly (or more frequent) cleaning.

While solar panels last, they are not indestructible and may be harmed by very harsh weather or a heavy blow. Look for cracks, warping, and other deterioration in your solar panels regularly. As soon as any damage is discovered, it must be fixed so that it does not worsen. It’s best to read the warranty of the solar panel manufacturer.

We analyse your energy data and determine if solar is possible in your scenario to guarantee that you can have an efficient renewable energy source that will efficiently produce energy for your home or business.

Regular maintenance and repairs if any defects are found

Solar panels last many years and generally require very little maintenance to function, so yes, you can usually just let them be. They only need a periodic light cleaning to ensure dirt, leaves, and other debris isn’t obstructing the sun’s rays.

You may need more extensive maintenance during periods of heavy snowfall, as inches of snow can hinder solar panels’ performance.

Check for damage after weather events.

Inspect your solar panels after a heavy hail storm for damage. This is also an excellent time to remove debris, small branches, or leaves that may have fallen on the surface during the storm. Check the surface for any small cracks and the frame for any dents.

Clean your solar system regularly.

According to common perception, a rooftop solar system should be inspected at least every five years. Similarly, solar panels should be cleaned regularly. The frequency of cleaning may be governed by various factors, including the environment around the solar system and how much dirt and debris may find its way onto the panels. Nonetheless, rough estimates often urge that solar panels be cleaned thoroughly at least once every six months.

Install Your Solar Panel System with CEC Accredited Installers

Our team comprises industry professionals, and Clean Energy Council accredited solar installers/engineers (CEC). We adhere to all Australian solar power standards and strive to provide the most satisfactory outcomes possible, regardless of your requirements. Furthermore, all the panels and inverters we sell are CEC-approved and feature Mono Crystalline perc technology to maximise efficiency and diminish carbon footprint.

Get Regular Maintenance to Help Your Solar Panels Last Longer

All your solar panels really require is an annual cleaning and checkup. The panels should not need any further upkeep during the year if they are functioning correctly.

Frequently Asked Questions

What are some benefits of using solar power?

They are a fantastic method to reduce energy expenditures while mitigating carbon impact. Solar panels cost is getting more inexpensive and the return on investment is better than ever.
A solar installation by Solar Galaxy can help prevent harmful greenhouse gas emissions, reducing global warming.

Solar panels last a long time, emit no pollutants, and are thus ecologically benign. They also lessen our reliance on scarce fossil fuels and traditional power sources. Solar installation services are offered by Solar Galaxy on residential and business sites.

What causes solar panel degradation in Australia?

A harsh operational environment significantly contributes to the panels’ rapid deterioration. How long do solar panels last? Rain, dust, and debris may all accumulate on solar panels, affecting the time solar panels last. To keep everything running well, you should establish a routine maintenance programme that includes semi-regular cleaning.

When should you consider replacing your solar panels?

If you want to know how long do solar panels last? They are incredibly robust, and with no moving components, they typically need little maintenance. The typical lifetime of residential solar panels is 25–30 years. However, some systems may last up to 50 years!

How fast do solar panels degrade in Australia?

According to data, high-quality solar panels degrade by around 0.5 to 3% each year on average compared to a ‘brand generic’ solar panel degradation rate.

How long do solar panels last with proper maintenance?

If you want to know how long do solar panels last? Solar panels have a 25-30 year average lifetime when appropriately used. However, a solar panel may continue to provide electricity for another 25 to 30 years. Instead, their output will be far below projections.

How long can solar panels produce energy at the optimum rate?

Solar panels’ typical annual deterioration rate is 0.5%, meaning their energy output will drop by 0.5% over time. You may expect your panels to maintain about 90% of their initial efficiency even after 20 years.
