I need a advice on how to power 100 Miners with a second energy source.

small info: i live in a place where you are limited to 12 Hours electricity by the Goverment, the other 12 hours i have to get a) a Private generator Company to host me (very expensive) b) get a standalone Generator and run it by myself (200kwh generator fuel consumption is about 60 liter per Hour at 0,58$ about 35$ a Hour or 350$+ a day)

I looked for Solar Panel Systems and so on but the Installation + ROI is to much.

Do you have any other solution?

Thanks in advance for replys
