Good - get them installs rolling.

As far as my lived experience goes, the main issue is the lack of insulation. It’s ridiculous how most housing lets the heat escape.

Good news. I installed 14 last year and expected if all went well to have them paid off in 12-14 years. Going by the last 10 months it will be less than 6. That’s from a combination of savings (1/3 of the energy bill) and also selling the excess to the grid (£164 worth so far) and all of Ttat’s at 55-ish degrees North too on a not ideal roof. Anywhere south of me should absolutely have them covering their roofs, there really isn’t a good reason not to.

Next up is top up insulation and replace the boiler with a heat pump. Possibly a second battery.

Yeah they need a lot of panels to offset the fact that they’ll be running at 10% efficiency lol
