The last few days I've been at an event in my caravan without access to electric hookup, instead being reliant on a factory-fitted solar panel (though I replaced the controller).
Today, despite being overcast during the morning, has generated the most so far.

Kind of a naive question about residential photovoltaics

How feasible is it to install a big battery at home to become self sufficient?

I was thinking 150 or 200 kWh? Do these systems exist, is sodium there yet, etc

There is space here for about a dozen 500 W or so panels, that’s just above 7 kWc as I was told (I don’t understand their math). Daily electricity usage is certainly less than 10 kWh all year, often closer to 6. Everything is electric, big spikes while cooking.

I know the summer would have a lot of over production that wouldn’t sell well, and spring/fall would probably be just about even; winter would likely need to charge at night (in the Paris area, France).

(I know how much the air/water heat pump makes this a crazy idea that requires cross seasonal storage that doesn’t exist yet, residentially, so let’s leave it out)

Just in case anyone wants to build a #victronenergy #victron #vedirect galvanically isolated USB cable here are some pics to reproduce my cheap DIY cables.
