This is one of the most helpful comments I've recieved!

I'll ask a quick question and then show my revised calculations. I must've misinterpreted the previous solar setup link. The system should be 12v. any more would be overkill. What do you think of this system? It has the MPPT controller you suggested :)

Solar Math: I used this calculator:

Fan: 4 Watt x 12 hr

Pump: 25 Watt x 6 hr

Air pump: 8 Watt x 24hr

Tank Heater: 100-watt x 8 hr

Etc: 10 Watt x 8 hr

Total Watt Hours per Day 1270.00

Watt Hours Required After Loss 1651.00

Kwh/mo 49.53

Peak Sun Hours Per Day 4.2

Minimum System Size 393 Watts or 2 Panels at 200 watts

Battery Bank: 150ah Minimum Maybe 2 or 3 of these to be safe
