Yeah solar power is much more affordable these days. I live in a vehicle so I have a 500w panel on the roof charging a 200ah lithium battery. I only use a laptop and steam deck, but could easily upscale. The whole system, including the victron controllers & shunt and the 2k inverter came out around £700, but I'm pretty sure stuff has only got cheaper since I bought it. I have way more power than I need in summer, though there are maybe two months in winter when I have to charge everything in daylight. I could always add a small wind generator if I needed. Renewables are totally feasible these days
