Re: Fag packet calculation time...

I must be missing something , the average cars petrol storage capacity is about 400kw hours worth of energy and a standard photo voltaic array will give 4kw in bright sun so assuming 10 hours sun- that is 40kw hours-ie we need 10 days of bright sun for 1 charge or if charged from the mains with a 60a supply ,we would need 28 hours -?????????
