We are looking at getting solar panels fitted but struggling to get quotes. The only one we’ve received is c. £11k for a 6.56kWp system if we add a battery it will be £8k (10kWh) or £12k for a Tesla (13.5kWh).
We have an electric car and are heavy electric users (both work from home, electric underfloor heating etc). so are keen to get solar panels, but payback looks like it will take 10-15 years depending on how quickly electricity prices rise.
Does this sound reasonable?
