I’m undertaking an “energy refurbishment project” (that’s what the architects said on the planning application) of our home. It’s the usual insulation, 3X glazing, etc, and also includes getting PV panels on the roof so that I can pay bulb less (sorry bulb!).
I’ve been given a list of panel options (Perlight 250W, LG Solar 285W, Bisol 285W, Sunpower 327W) but what’s a good criteria for comparing them. I know their price, their output, their warranty period.
If anyone has bought pv panels recently, do you have a spreadsheet that I can update?
