It's game-ified and an alien planet. Could be a tool to learn how to think of the problem. Quick ballpark numbers. Common solar panels are between 15 and 20% efficient. Numbers for the _surface_ of the earth (not the upper atmosphere) are quoted as about 1000W per square meter in a search. I assume that's a peak number. Since I don't want to think about weather, calculus, or any other factors for a napkin estimate, can we agree that's 8 hours of useful output at 1KW of input power per hour? So over a day 1 meter of solar panel would generate between 1.2 and 1.6 KW / day? I'd also very crudely extend that to 75% of the daily output must exist as a storage buffer. (Gut feeling more than anything else.) 1.2KWd to 1.6KWd of daily generation per square meter. 0.9KW to 1.2KW storage; per square meter for a day. I have trouble visualizing that though. https://en.wikipedia.org/wiki/Deep-cycle_battery https://en.wikipedia.org/wiki/Deep-cycle_battery Suggests that the discharge should only be to 50% on a regular basis for the most economy of material use (and thus cost). Double the above estimates for the storage bank. Searching for "deep cycle battery solar" I see many results for 12V 110AH batteries, just a tiny bit more than the 1200KW storage value I guestimated earlier. Around 200 dollars per battery, about 13 x 7 x 8.5 inches (rounded up). So a big honking consumer 'truck' / SUV battery sized deep cycle battery, but double that up for wear prevention. Though I still prefer baseload generation capacity for industrial and 24/7 loads. Solar can be a good peaker for AC use and waking consumer stuff.
