Wiring Solar Panels In Parallel

Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same.

Wiring solar panels in parallel.

Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. If you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps the entire array would be 12 volts at 20 amps. Connecting panels in parallel requires heavier wire to handle the higher current 25 amps vs 5 amps in the examples above and you need more wire to make all the connections to the different panels. If we have two solar panels with the same voltage but different wattage there is no problem.

They can be wired in parallel. When an installer wires your solar panels in parallel each panel s wires are connected to a centralized wire leading from the roof. The amps of electrical current for each solar panel are summed together but the system voltage stays the same. Wiring solar panels in parallel.

So if you wired the same panels from before in parallel the voltage of the system would remain at 40 volts but the amperage would increase to 10 amps. Couplers provide a nice easy way to wire up two solar panels say if you are wiring up for a little cabin or a boat or an rv.
