Rooftop solar
When plug-in solar is not enough
An 800W system covers a slice of a household's electricity. If your calculator result says you need considerably more, a full rooftop installation is the honest answer — and quotes vary widely.
Why compare more than one quote
Prices for a comparable rooftop array routinely differ by thousands of pounds between installers, and so do panel choice, inverter quality, warranty terms and scaffolding assumptions. One quote tells you nothing about whether it is a good one.
What we do with your details
- We pass them to vetted installer partners so they can quote.
- We only do that if you tick the consent box.
- We do not sell your data or add you to marketing lists without consent.
- You can ask us to delete your record at any time.
What to ask an installer
- Total system size, panel model and inverter model, in writing.
- Expected annual generation and the assumptions behind it.
- Warranty terms for panels, inverter and workmanship separately.
- Whether scaffolding, DNO application and any roof repairs are included.
- Certification and membership of a consumer protection scheme.
PlugInSun earns a referral fee when a reader requests quotes through this form. That fee does not change the price you are quoted and does not influence which installers we work with beyond our vetting requirements.
