Yeah but the sun doesn't shine during the night.

I know but lead-acid and batteries aren't stellar for the environment either.

I have a similar network setup (actually a bit bigger) and a much larger computation setup. I also have a 20kw 53 panel solar setup, and a complete 42kwh battery setup.

Overall power usage throughout the year for me is pretty high, on the order of 8MWh/month, and I get about 25 MWhs of total solar production. My servers and network gear take about 4kw sustained, which is 35MHws, so my solar covers about 70% of my computation and network power usage. I live the NW, so I produce most of that power in the central 5 months of the year.
