For all you DIY fans and hackers: 1) You can install solar panels yourself [1]. Most of the cost today is installation not the panels. You don't necessarily have to put them on the roof of your house. Installation on e.g. a car port or just on the ground is usually much easier. 2) You can save money by building your own battery from B-grade (safe but not good enough for electric cars), LifePo4 3.2V cells, and a BMS (battery management system) sourced directly from China. If you know German, this video is a great start: https://youtu.be/97T3TAV51sM https://youtu.be/97T3TAV51sM He built a 10kW solar plant with a 11kWh LifePo4 battery for no more than 7'000 USD. He's using that power in part to heat is home with AC and estimated that it will amortise within a handful of years. Also has a great forum, again in German, https://www.akkudoktor.net/forum/ https://www.akkudoktor.net/forum/ Looking forward to any good English sources. I'm currently building a van for remote work. Already live and work in it full time for a few months now. I have 5.5kWh of LifePo4 battery that cost me about 1'500 USD. Bought in Germany, incl. housing and BMS, not DIY. Would already be much cheaper now, just half a year later. I currently have 200Wp solar on the roof, which is enough for work. Planning to upgrade to 900Wp soon, to also run AC and cook via induction instead of gas. AMA. [1] You might want to check the building codes in your area. Like many here, I'm more of a EAFP guy.
