It is the solar companies who are ripping off the public.
When they sell solar systems to residential customers they don’t factor in this buy sell factor or the customer’s usage patterns and wind up selling a system where customers are giving hundreds if not thousands of dollars of electricty to the power company for free every year. (At the end of the year, any excess electricity credit dollars are given to the power company for free.)
Yes, I side stepped this aspect. Although I believe it is in decline as 3k+ home systems are becoming affordable for personal investment now.
The market here was flooded with companies whose model went like this:
You present a small deposit, a thousand pounds or so.
They install several thousand pounds worth of panels and GTI in your home.
You can use what you like.
The excess electricity when you are out all day is sold back to the grid at wholesale price.
The money for the electricity sold goes to the investment company/bank bank rolling the solar installer.
The trouble is the contracts involve horrid clauses meaning you never own the panels, the investment company has a long term 10-20 year lease on your roof. You can't sell your house without lengthy proceedings to transfer the lease or terminating the lease early with fines AND pay to have the panels removed and returned ... or more fines.
The government was actively supporting these companies and helping to fund them.
