Connecting Solar Panels Of Different Wattage In Parallel

With parallel solar panels the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.

Connecting solar panels of different wattage in parallel.

There are two ways to wire up solar panels. Connecting solar panels in parallel. Then they are connected to the charge controller or to the inverter of the solar system. They can be wired in parallel.

Typically solar panels of specific or matching current needs to be connected with each other in series. Wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well. If we have two solar panels with the same voltage but different wattage there is no problem. You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above.

This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency. Firstly lets take a look at connecting solar panels in series. Solar panels are usually connected in series to obtain higher output voltage. 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.

Comparing solar panels in series vs. Should you connect a 3a solar panel to a 3 5a solar panel the all round current will probably be pulled down to 3a. Find out the safe way use them in our guide. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.

Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same. You can use solar panels with different wattages and brands but you have to connect them correctly. On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.
