Not OP but I rent and have to use my deck for solar. I only have 2 x 100W panels that sit on the ground, and that feeds a 135Ah AGM battery in a box. The box has a 500W inverter on top connected to the battery and powers a mini fridge, deck lighting, and a few other things out there. I would love to put them on the roof and my landlord would probably be cool with it, but I take it camping all the time so it's nice being able to pack them up quick.

Panels and batteries are relatively cheap (and getting cheaper) to the point that it can makes sense to have purpose-built setups.

From an actual practicality sense, the whole setup doesn't make that much sense. You could drop the files on a static site host and it would use 0 watts while not in use and a negligible amount while in use.

Another interesting case would be to use an API to get your areas power generation stats and when the wholesale pricing is low due to solar/wind generation peaks, charge your battery off the grid.

See the previous article I link at the top about my situation.

I think the OP lives in an apartment, where that kind of invasive mod is not possible.
