RE: HOW EXTREME E CREATED ITS OWN ZERO-EMISSIONS POWER SOURCE18 Jul 2020 10:24
let's not forget the efficienxy of solar is around 22%.
The sun produces 1000w per m2 so a 1m2 panel will produce around 220w.
So for 2mwh based on production over 40 hours you would need
2,000,000 Watts/ 40hrs = 50,000 w/hr
1000w x 0.22 = 220 watt per m2 = 225m2 of solar PV
Not forgetting that solar PV is probably not ideal for remote locations such as the artic as it is not particularly robust and can be quite fragile.
