Lessons from a year with solar power

EV Info

It was one year ago that we decided to add solar panels to our roof. According to the Department for Business, the average cost for standard electricity in the UK in 2020 was 17.2p/kWh. That rate would give the LEAF a cost of 17.2 * 24 to drive 100 miles. In other words, power is energy per unit of time. Power is watts.
