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.

Solar PV: owners’ views

We asked 1,987 Which? members who have solar PV panels to tell us about their experiences, including:

  • Electricity generation
  • Ease of using the system
  • Customer service of the brand (where applicable)
  • Value for money

We also asked whether their solar panels earned them as much money as they expected.

We then used these results to calculate an overall customer score for each brand, plus star ratings for the key elements listed above.

We have results for 15 of the most popular solar PV brands, including Hyundai, LG, Panasonic, Sanyo, Sharp and Solarworld.
