Hyundai Kona 64kW premium - 2021

What the others have been saying really. My baseload usage is about 9kWhr per day when the house is occupied. So to charge your car I'd need to generate 20kWhr as a minimum. I have a 3.7Kpa system split 50:50 on two roofs (west and south facing) with a 4kWhr battery. I got 20 kWhrs for about 30 days between the start of May and the end of July last year (ie 30%of the time). The excess was exported for about 5p per unit.

My December average was 1.5kWhr, but that hides 15 days when I generated less than a kWhr. That suggests as a bare minimum to meet the needs of my house and 11kWhr daily for a car (mine takes 60...so not even thinking about it) I'd need an installed capacity of around 80 kW

There is, of course, no such thing as free electricity. I will try to put as much of the excess as I can into the car (not had it long enough for this to be a thing yet)...which will cost me 5p a unit in lost exports, but that equates to around a penny a mile, which is better than a poke in the eye. 😀

Hope this helps.
