What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
Can I get solar panels on an east or west facing roof in Ruislip?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
How does shading affect solar panels in Ruislip?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
Do solar panels work in winter in Greater London?
Yes, solar panels generate electricity all year round. While output is lower in winter, Greater London still receives usable daylight hours even in December. Annual generation figures (3,840 kWh for a 4kWp system) already account for seasonal variation.
