We hijacked a different solar PV thread, and are moving it here to continue discussing the technicalities of solar PV installations. This is the last response: “One last thing* another reason for…

Therefore 33.6GW nuclear electricity capacity, 60.9GW of waste heat capacity, 30GW of top up heat capacity from heat only reactors. Upto 272 TWh electricity Upto 490 TWh…

Can 3 million EVs replace 30 million oil cars?
Seems like a ridiculously low number doesn't it? How can 3 million robo EVs replace 30 million human cars in the UK. The basic idea is that the robo EVs do 10 x the average mileage as the human cars so you only need 1/10th as many......But surely there are more than 3 million cars on the road at peak commuter…

Ovo v2g - does it make sense?
Haven't looked at the details but basically ovo pay 6p per stored unit exported on top of the standard unit rate which it obviously cost to charge the battery in the first place. Not sure if there is any option for time of day arbitrage (fill batt using cheap rate, sell back at peak rate) Not sure if you have to be on a…
