2 years agoWe have a 20 panel home solar system, with 10kWh of battery storage. Most days we don’t use any external power. In summer we’re exporting 20-25kWh per day into the grid. Payback will be around 6yrs, equivalent to earning 15% interest on the money we invested (£14k 'ish).
Sensible decision - we need the unions engaged with Labour.
