Those numbers sound wrong.
I have 7.8kw in Canada, and if I paid out of pocket payback would be 6-7 years.
We pat $0.13 per kWh from the grid, get a one for one credit on anything we feed in. System makes 7.8Mwh in a year.
What are your friends numbers?
Grid price is also pre-approved to increase not less that 5% a year forever, so it will only go in my favour.
In spain he pays more than that on average, and only gets €0.04 for sold KWH. If it was one-to-one credit offset, as you have in Canada, it would certainly be very profitable.
So then just use most of your power during the day and you’re better off than Canada.
It’s not hard to use heavy power appliances only during the day.
