Wiring Solar Panel Arrays
Solar Panel Voltage Question?
I am building a solar panel I have wired in series 36 .5 volt solar cells to produce 18 volts I have another panel that has 34 .5 volt solar cells to produce 17 volts. Any issues with wiring these 2 arrays in Parallel? I.E. would the smaller array take usable power away from the larger array?
The solar panels should have the same output voltage. If you wire them in parallel, I doubt that the 34 cell panel will add any current to the output. Do the solar cells panels have about the same output current? If so you can hook them in series to increase your output voltage. If not then you should remove 2 cells from the 36 cell panel so that both panels have 34 cells, then you should be able to hook them in parallel and the output currents should add to give you more power.

Sunforce 7 Amp Charge Controller $17.41 The Sunforce 60012 7 Amp Charge Controller prevents overcharging of 12-volt batteries. It is intended for use with 12-volt solar panels, and can handle up to 7 amps of array current and up to 100 watts of solar power. The controller is easy to use with a charging light that indicates that your battery is charging, and a green light that indicates a fully charged battery. The 60012 measures 4 x 1 x… |
