Do solar panels work in the North East?
Yes. Solar panels generate electricity from daylight rather than heat, so they continue to work in cloudy conditions. Your design will include a tailored generation estimate.
Do I need battery storage?
Not always. A battery can help you use more of your own power later in the day, but we will assess whether it suits your usage and goals before recommending one.
How long does installation take?
Most domestic installations can be completed quickly once the survey, design and permissions are in place. We will confirm your timetable before work begins.
Which areas do you cover?
We are based in Darlington and work across County Durham, Teesside, the wider North East and Yorkshire, with larger projects considered further afield.
