Again, I used THEIR numbers. My only "SWAG" was the battery conversion efficiency of 80%, which I supplied from my expertise of 30 years as an electrical engineer designing switching power supplies, big and small.
Please tell me what's wrong with this analysis. I want a PV backup at my country home (not for A/C though), so I need to do this right.
I can’t wait to see them dump batteries in an emergency. I’m an EE. This is the stupidest idea ever.
Not saying it can’t be done, but nothing compares on an energy/lbs basis like petroleum-based fuels.
