A rough guide, not a quote. It assumes your bill is mostly electricity use at the unit price shown, typical UK sunshine for your roof direction, and that you use about 40% of your solar at home without a battery or about 75% with one. Your real figures depend on your roof, shading, usage and tariff, and your survey will confirm them. 0% finance is available, subject to status.

How we size your systemWe compare your yearly electricity use with what your roof can generate, then pick the nearest standard size from 4kW (about 8 panels) up to 8kW (about 17 panels), based on 480W panels. Need bigger, or a commercial system? We install any size.
Why a battery helpsWithout a battery most homes use around 40% of their solar and export the rest. With a battery that can rise to around 75%, because daytime solar powers your evenings.
Getting paid for spare powerSolar you don't use is exported to the grid. With an MCS certified installation you can sign up to the Smart Export Guarantee and get paid for it.
