Hello everyone,
I have a saltwater fish tank that required 2 pumps to run 24/7/365 with some LED's that run for 8 hours a day (all devices are on 24V DC). With my current solar system, 250W panel (30.7V;8.1A; 60 cells) with 4 brand new GC2 battery at 215A, it barely enough power the pumps for 24 hrs if I get good sun. I"m planning to add another panel 360W, 38V, 9.8A, 72 cells (cost less than 60 cents per wattage), what is the best setup for it ?
I also have another solar setup for my fresh water tank with 175W, 35.8V, 4.9A, 72 cells to charge my 4 deep cycle battery at 55Ah each in 24V setup.
Here is the list of all the parts I had:
Load:
Can I connect the 2 panel with different voltage/Wattage in parallel as shown on the drawing below? I
If not, what is the correct setup for it?
Thank you in advance for all your help.

- BP Solar panel: 175W, 72 cells, 35.8V, 4.9A
- SunTech STP250-20WD panel: 250W, 60 cells, 30.7V, 8.1A
- Goftcart battery: 6V GC2-215A x 4
- Deep Cycle battery: 12V-55A x 4
- Cheap Chinese MPPT charge controller.
- LG panel LG360N2W-B3 (from friend): 360W, 72 cells, 38V, 9.8A
Load:
- 24V @ 3A pumps ==> 72W/Hr ==> 1728W/Day (need to be run for 24/7/365)
- 24V LED's light @ 6A ==> 144W/Hr (time ON can be adjust, to meet the battery supply)
