RE: Competition for lithium is about to get a whole lot worse.6 Jun 2022 14:45
As a point to make on battery and solar. I have built a 15kwh battery out of second hand laptop batteries. I have 5.2kw of solar on South facing roof. I am on oil for heating but use electric to heat water. Last week I used £1.38 of electric off the grid and no oil to heat water. With a reasonable price of say £8000 you could have a brand new LFP battery system with decent inverters that would work except for winter quarter. I save about £1200 a year and get paid circa£450 for exported power. If it was at community level I am sure it would be cheaper as scale would work in your favour then.
