Stand up and turn round and bend over, you sound a bit muffled. In winter a photovoltaic system such as mine (1.5 kW plate capacity, 20 kWh of batteries) would provide enough charge to run an EV for 5 km, on an average day. That almost gets me to a paved road. Of course for a week at a time we don't even get that much charge in a day. And oddly enough we have other uses for the electricity, such as running the house. So for a reasonably sized system a genny is not only cost effective, it is essential.
With 1.5kW and 20kWh of batteries you have enough energy to run your house?
I´m very interested on this as I´m doing some numbers to analyse what should be the investment to become off-grid, and 1.5kW didn´t seem enough to me, even for a small house.
I´ve been looking at systems wich go from 3kW (standard house) to
6kW (big house with pool, paddle court, 2 jacuzzis...) with 150Ah batteries, wich is way bigger than my needs, but I think is a good reference.
