Your solar questions for Christchurch

Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.

How does shading affect solar panels in Christchurch?
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.

Yes, solar panels generate electricity all year round. While output is lower in winter, Dorset still receives usable daylight hours even in December. Annual generation figures (4,200 kWh for a 4kWp system) already account for seasonal variation.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
Do I need a smart meter for solar panels?
