I don’t get it. For me it seems like „it’s not 100% the best way, so you have to stop it.“ Sure, a car-free, equal society that treats nature as family is the way to go. But why do they try to kill the first movers? Because Elon Musk is a weirdo? Why not stopping the coal diggers a few kilometers to the east? Or the chemical plants to the south first? That’s such a brain fuck.
If you just need the energy for the pool, a small setup without battery is all you need. Saves you half the price. Panels and inverters are around 900€ in Germany. Putting a battery on it makes another 1,200€ and it makes sense only, if you need power in the evening.
