How about solar power Generations? Does anyone used one before?
Yes, it all depends on what you plan on powering.
A marine battery 24F, 40 watt solar panel, and 300 - 600 watt dc to ac power inverter can acquired cheaply, ie auto parts and Harbor Freight.
A flexible 15 watt solar panel is nice since it’s light and doesn’t shatter if dropped. Large deep cycle sealed lead acid battery can work to for smaller applications.
For the most part, you can forget about running most large applicances, well pumps and heaters on solar power systems, unless you have large kilowatt storage capacity costing ten thousand+.
