How much does it cost and will it need to be maintained?
Prices for PV systems vary, depending on the size of the system to be installed, type of PV cell used and the building on which the PV is mounted. Typical prices range from £5,000 to £7,000 for each kilowatt installed, depending on the system type. PV panels require minimal maintenance and are designed for approximately a 25 year working life, with performance even after 30 years being 80% of that when new. Although the panels need to be reasonably clear of dust and debris, the rain is sufficient to clean them on a standard pitched roof, just make sure trees don’t begin to overshadow them. We do however offer annual maintenance should you wish your panels to be checked and cleaned if required.
