Solar panels are a long term investment and it's prudent to keep the system in good working order. Like a car needs an MOT, or a boiler an annual service, a much larger investment the size of a solar array is definitely worth checking periodically to ensure everything is ticking over. There are several reasons for doing this, read on for why you should get your panels serviced and cleaned regularly.
How Often Should I Get My Solar Panels Serviced?
You might not need to invest in solar panel servicing every year, but at Spirit we recommend servicing at least every couple of years, especially for larger commercial arrays, and cleaning more frequently than that. These services come with with a price tag, depending on the size of the system, however it's not as expensive as you might expect and the loss in efficiency from not getting panels serviced far outweighs the cost of keeping the system clean and up to scratch with a regular service. Additionally, particularly for larger commercial systems, regular servicing may be a requirement requirement for any insurance policy taken out on the system and the normally generous warranties on the panels themselves may be void if not serviced regularly, so it's definitely worth checking the paperwork that came with your system for a gauge on how regularly in should be serviced. Generally, 1-2 years for servicing and annually for cleaning should be sufficient.
