Connecting Multiple Portable Solar Panels

How to connect two solar panels to one battery it s all in the wiring.

Connecting multiple portable solar panels.

Parallel series and a combination of parallel and series. Wiring solar pv panels in parallel the next basic type of connecting solar panels is in parallel. For example if you have two rng 100d 100 watt panels each panel will produce about 5 29 amps. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.

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. Disconnect everything reconnect both regulators to the battery on their own no solar panels connected leave for 15 minutes reconnect solar panels to regulators. There are 3 ways to connect solar panels. Connecting these panels in parallel will produce 200 watts 18 9v and 10 58 amps under optimum conditions.

Connecting two portable solar panels or any other type of solar panel same wattage in parallel will multiply the total power output current by 2 and keep the system voltage at the same level. I spoke to the people at wedgetail campers about how the two solar inputs were wired. Parallel solar panel connections should be made using y connectors available at redarc. For this example i am showing you connecting panels that are for a 12 volt system.

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. The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. 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. When your panels are connected in parallel you add the amperage together but the voltage stays the same.
