Is Solar Panel Maintenance Necessary?

Solar panel maintenance

Solar panels are undoubtedly a great and famous investment in Australia. One of the major advantages of installing solar panels is that it requires little to no maintenance. However, this benefit raises several questions about solar panel maintenance in the minds of homeowners. 

Compare Solar Quotes believes that it is the right of the homeowners to receive proper answers to their queries. And that is why our Compare Solar Quotes team will answer some of the most asked questions about solar panel maintenance. 

Do Solar Panels Require Maintenance?

Yes, solar panels do require maintenance, but the amount of maintenance they require is very little. The only maintenance that solar panels regularly require is a gentle cleaning of the solar panels from dirt, debris, bird droppings, and so on. And by regular cleaning, we mean that the panels need to be cleaned at least once or twice a year. 

However, solar panels will only require major maintenance when they undergo physical damage or the energy output decreases significantly. Solar panels are pretty durable, so the chance of physical damage is very low. In cases like this, the solar panels will be repaired or replaced by the professionals. If the solar panels come with a decent product warranty policy, then there is no need to worry about the cost. 

How To Maintain Solar Panels?

If your solar panels are installed at a certain angle, then you are in luck. Rainfall easily cleans up the dirt, debris, etc., from tilted solar panels. However, if you have flat solar panels or live in a dry region with very little rainfall, then you have to clean the solar panels manually. 

But the good news is that solar panel maintenance does not require much work. Clean the solar panels with soapy water and a solar panel cleaning brush, and you are good to go. Well-maintained solar panels will last longer than the neglected solar panels.

You may have to clean your solar panels in winter after a heavy snowfall. The energy generation rate of solar panels in winter is a little slower than the energy generation rate in summer. Accumulated snow on the solar panels can reduce this rate even further. 

If you need to use water to clear the snow from the solar panels, ensure that the water is lukewarm. Solar panels are made of tempered glass; thus, the use of extremely hot water can cause the panels to crack. This cracking usually occurs due to the high temperature difference between the water and the panel. 

Is there a difference between the maintenance of ground-mounted and roof-mounted solar panels?

Both ground-mounted and roof-mounted solar panels are cleaned in the same method, using the same items. However, the only difference is that the solar panels mounted on the ground are more easily accessible. Cleaning the solar panels mounted on the roof requires proper precautions and care as they are hard to access. 

How much does solar panel maintenance cost?

The solar panel maintenance cost varies depending on the method you choose to clean the solar panels. If you choose to clean the solar panels by yourself, then all you need is a non-abrasive brush and soapy water. This cleaning method will cost you less than $10. However, if you choose to get the solar panels cleaned by professional solar panel cleaning services, then it would cost you about $150 to $200. 

How Often Do Solar Panels Require Maintenance?

Neglected solar panels lose their efficiency faster and last for a lesser period of time than the well-maintained panels. How often solar panels require maintenance depends on the area or region you live in and how the panels are installed. Tilted solar panels usually get cleaned of the dirt and debris due to rainfall. So cleaning the solar panels once or twice a year should be more than enough. 

However, if the area or region where you live does not get enough rainfall or if you have flat solar panels, then the scenario is different. In cases like this, the solar panels have to be cleaned manually and at least once every six months to ensure the top performance of the panels. 

Get the solar panels checked by professionals at least once a year to see if there are any issues with wiring, mounting, and so on. Such issues can also cause the efficiency and lifespan of the solar systems to decrease. 

Do the extreme weather conditions impact the solar panels?

Solar panels are well-known for their durability. The majority of the solar panel manufacturers conduct severe testing on their solar panels to ensure that they will survive the extreme weather conditions, and Australia is well-known for its extreme weather conditions. 

Although solar panels are very durable, they are not completely indestructible. Extreme weather conditions can cause physical damage to solar panels on rare occasions. However, there is nothing to worry about if your solar panels come with a good product warranty policy. The cost and hassle of repairing and replacing the solar panels will be covered by the warranty. 


Overall, the solar panel maintenance is nothing too hard or complicated. Just make sure that you get a good product and performance warranty from the solar panel manufacturer and take proper care of your solar panels. Clean your solar panels regularly and do not allow dirt and debris to build up on the panels. 

Solar panels provide us with clean, renewable energy, help us to save money on electricity bills, and reduce our carbon footprint. Solar panels are not only beneficial for our wallets but are also beneficial for the environment. A little maintenance of the solar panels will ensure that we are receiving the best value for our money. It will also ensure that the solar panels are working at their peak efficiency.
