What Affects Your Solar Quote
Understanding these three factors helps you evaluate any quote you receive.
System Size
A 3kWp costs £5,500-£6,500. A 6kWp costs £9,000-£12,000. The right size depends on your electricity usage and roof space.
Panel Brand
Premium panels (Sunpower, REC) add £500-£1,500 vs budget brands (Jinko, JA Solar). Premium panels perform better in Scotland's diffuse light.
Roof Complexity
Standard pitched slate roof is cheapest. Flat roofs, multiple arrays, conservation areas, and difficult access add cost. Scaffolding can add £400-£1,000.
