It’s pretty easy to find solar panels for less than $1 per watt and a good quality controller for $100 to $200 plus wiring etc. The rest is the same regardless if using solar or not.
I have a small system to run fans, LED lights, charge my devices, and run a radio. Heating, cooking, and showering I do by more efficient means (using electricity to heat things is hugely inefficient). 150 watt solar panel for $140, second hand charge controller off eBay for $40, and maybe $35 on DIY brackets and wiring. All assembled myself. Solar isn’t expensive if you take a few hours to study how it all goes together and learn how to solder and use heat shrink.
