Should I pay more for a home with solar?

Yes — solar adds real value. A 4kW system saves £580-£1,100/yr. Even a 10-year-old system still has 15+ years of savings ahead. Factor this into your offer — but check condition first.

What if the panels are leased?

Proceed carefully — you'll inherit the lease payments. Check: monthly cost, remaining term, buyout options, and whether the panels generate enough to justify the lease. Owned panels are always preferable.

Can I get the system inspected?

Yes — ask an independent MCS installer to inspect the system (£100-£200). They'll check panel condition, inverter health, wiring, and estimated remaining lifespan. Worth it for peace of mind.

Will the warranty transfer to me?

Product warranties (panels, inverter) transfer with the property automatically. Installation workmanship warranties may or may not transfer — check with the original installer.

What to check when buying a home with solar?

Buying a house with solar panels is a great investment — but check these 10 things first: (1) MCS CERTIFICATE — proves proper installation by a certified installer. (2) PANEL AGE — how old are they? Panels last 25-30 years. (3) WARRANTY STATUS — check remaining years on panel and inverter warranties. (4) INVERTER AGE — inverters last 10-15 years, may need replacing soon. (5) ANNUAL GENERATION — ask for monitoring data or electricity bills. (6) SEG CONTRACT — is there one? What rate? Can you transfer it? (7) DNO NOTIFICATION — should be on file. (8) CONDITION — any visible damage, bird mess, or shading issues? (9) LEASE OR OWNED — if leased, what are the terms? (10) EPC RATING — does the EPC reflect the solar installation? A 5-year-old system with good documentation is a £5,000-£10,000 bonus on the property.
