During the pandemic I built a number of simple indoor solar systems, setting panels in the lower part of my windows (I keep the shades open at the top) and hooking up to either a homegrown controller/battery/inverter system or a jackery. The jackery is roughly 30% more expensive but feels a lot less fragile than my homemade stuff, and I've moved all my device charging (tablet/phone/power tool battery) charging over to these systems. It was a fun project! Cabling is always the part that sneaks up on you so make sure to plan out the cabling / what plug types you want / crimp or buy / etc. ahead of time.
