Regular servicing and cleaning of your solar system can increase output by up to 12%. And by regular, we only mean once every 2 years...
If you're having problems with your solar inverter or system monitoring, please try out our troubleshooting guide.
All electrical systems should be inspected and tested periodically, and solar PV and battery storage systems are no different. Here are the key reasons to service your system:
As a minimum we recommend testing and inspection should be undertaken once every two years by a qualified electrician, trained in the relevant technology.
We offer a solar panel service on a ‘one-off’ basis, or as part of a more comprehensive package with on-going support. Our prices start from £200 inc. VAT for a single inverter, single phase system up to 10kWp.
"We had solar panels installed in 2011 but our supplier has since gone out of business. Recently, after a squirrel chewed into our loft we decided to get a vermin guard fitted to the panels to avoid any rodent damage to the wiring. We contacted Spirit Energy and they fitted a guard including arranging the scaffolding and also cleaning the panels. They also suggested doing an electrical check and found a problem with the original installation wiring which they have corrected. We found them very efficient, helpful and friendly and will certainly use them again if we need any further work or advice."
On a sloping array panels will be cleaned by the rain as the glass on the panels is self-cleaning. However, if your panels are in an area of high debris or pollution, or if they are installed on a flat roof, we recommend the panels should be manually cleaned every year or every two years.
Where possible we will clean the panels from the ground using a low-pressure washer and a long lance. In some cases we will use the harness lines already in place on the roof. In other cases we will use a cherry picker.
A study by Google on their system in California suggested that it’s worth cleaning flat roof panels at least once a year at the end of winter; they claim the yield on their flat roof system in particular increased by 36%.
We offer module cleaning; our prices start from £100 inc. VAT for a single inverter system up to 4kWp.
