Solar panels are a fantastic investment for your property, commercial or agricultural premises. Although you may think that solar panels may need maintenance, there is actually little maintenance required to keep your solar panels running effectively. This article covers the maintenance that you need to carry out on solar panels during their lifespan when you are likely to need to replace your solar panels and your inverter as well as maximising the efficiency of your solar panels. As a general snapshot:
- Solar panels should be professionally looked at or serviced every 5 to 10 years.
- Solar panels require little to no maintenance and just need to be washed with water and a soap solution or a specific solar panel cleaning product. This can be cleaned every 5 years or more regularly depending on how dirty your solar panels get.
- Solar panels have a lifespan of 35+ years. You may want to consider upgrading after 10 years due to better technology being available and ensuring optimal efficiency.
- Solar panel inverters typically need replacing once in a solar panel PV system’s lifetime and replaced every 10-12 years. You can also consider investing in new technology when it becomes available as this can be retrofitted into your solar panel system.

Your solar panels shouldn’t become damaged except for extreme weather incidents or other factors such as birds damaging the solar panels. These systems are sturdy in construction so they shouldn’t get knocked out of position during their lifespan. If this does occur, then our team will need to re-align your solar panels and check for other damage.
Solar panels should last 35 years but you may want to consider an upgrade sooner as they lose efficiency during their lifetime. The inverter can be upgraded when new technology becomes available and it will typically require a replacement every 10 to 12 years. Your solar panels should fully pay themselves off in 8-12 years so after this point, you are generating free electricity for your property.
