South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
How does shading affect solar panels in Cirencester?
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.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the DNO notification (G98/G99 application).
