Sectors and services FAQs
Which sector page should I read?
Pick the one closest to your building. The figures and packages are illustrative across every sector, and your own assessment uses your actual roof and bills rather than the sector average.
My building does not fit any of these sectors, does that matter?
No. These pages cover the most common commercial roof types we see, but Business Solar UK assesses any business premises with suitable roof space, regardless of sector.
What size system will my business need?
This depends on your roof space and your daytime electricity use. Our system size guides give a rough steer, and your assessment sizes a system specifically for your premises.
Do all sectors qualify for a fully funded PPA?
Sites with a large roof and strong daytime demand are usually the best fit for a power purchase agreement. Your assessment will tell you whether a PPA, or one of the other three routes, suits your building.
