Solar panel brand reviews
You can use our results to see which brands are recommended most highly by those who own them, and which are rated best value for money.
Solar panels are a long-term investment, as they’ll be on your roof for 20 years or more. That's why, in spring 2019, we asked solar PV owners about their systems - including whether they’d recommend their solar panels, and if they produced as much electricity as they expected.
