Are solar panels a scam?
No, solar panels are not a scam: they are a proven technology that saves most UK homes £400 to £1,150 a year with a 6 to 10 year payback. The bad reputation comes from a minority of pushy sales tactics and inflated savings claims, not the panels themselves. Buying from an MCS installer with itemised quotes and realistic figures avoids the pitfalls.
Sales red flags to avoid
- High-pressure, today-only discounts and rushed contracts.
- Savings or payback claims that sound too good to be true.
- Reluctance to provide an itemised, written quote.
- No verifiable MCS certification or local references.
How to buy with confidence
Use an MCS-certified installer, get at least three itemised quotes, and sanity-check the savings against a neutral estimate. SunSum's calculator gives realistic, data-backed figures with no payment details required, so you can compare any sales pitch against an honest baseline before committing.
Frequently asked questions
- Why do people say solar is a scam?
- Usually because of aggressive door-to-door or phone sales and exaggerated savings, not the panels. The technology and the savings are real.
- How do I avoid a solar scam?
- Insist on MCS certification, itemised quotes and realistic figures, and never sign under pressure. Compare against an independent estimate.
