Can't understand why new houses and factory building's are not made to have solar panels fitted when being built. I know it may not be worthwhile in some circumstances but generally I would think it cheaper than retrofitting.What would the cost be to provide all suitable homes with solar panels and a battery to give a continual availability of electricity?
Houses with solar can't use all they generate and sell the surplus to the grid.
This can't be more expensive the a nuclear power station, just looks ugly.
A better option in my opinion, any thoughts?
