Question 1

Do solar panels work in Scotland?

Accepted Answer

Yes. Solar panels work on daylight, not direct sunlight. A 5kW system generates 4,000 to 4,500 kWh annually in Scotland, enough to power most of a typical household's daytime electricity consumption.

Question 2

How much do solar panels cost in Scotland?

Accepted Answer

As of May 2026, a 5kW residential system arranged through our installer partners typically costs 6,000 to 8,000 pounds installed. With battery storage, expect 12,000 to 16,000 pounds. Typical payback in 6 to 9 years.

As of May 2026, 0 percent VAT applies to solar and batteries until 31 March 2027. ECO4 and GBIS offer free insulation for eligible homes.
