Connecting Multiple Portable Solar Panels

Parallel solar panel connections should be made using y connectors available at redarc.

Connecting multiple portable solar panels.

In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage. I spoke to the people at wedgetail campers about how the two solar inputs were wired. The wedgetail camper has two solar inputs via red anderson plugs. How to connect two solar panels to one battery it s all in the wiring.

Wiring solar pv panels in parallel the next basic type of connecting solar panels is in parallel. Parallel series and a combination of parallel and series. Connecting these panels in parallel will produce 200 watts 18 9v and 10 58 amps under optimum conditions. When your panels are connected in parallel you add the amperage together but the voltage stays the same.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. Place the two solar arrays in series for vmp 35 volts then connect to a 20 amp mppt charge controller which takes the high voltage low current from the solar array and efficiently down converts to the low voltage higher current for charging the 12 volt battery bank. For example if you have two rng 100d 100 watt panels each panel will produce about 5 29 amps. Disconnect everything reconnect both regulators to the battery on their own no solar panels connected leave for 15 minutes reconnect solar panels to regulators.

Connecting solar panels in series the series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter. The first is on the roof. Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while keeping the same voltage. For this example i am showing you connecting panels that are for a 12 volt system.
