Pwm charge controllers will use the incoming voltage needed for to charge your 12 24 or 48 volt battery bank.
Connecting rv solar panels in parrallel.
Connecting them in series or parallel will then depend on the type of solar charge controller you plan to use.
For example if you have two rng 100d 100 watt panels each panel will produce about 5 29 amps.
So if you wire together a 100 watt solar panel and a 175 watt solar panel in parallel you ll get a total of 275 watts.
That means if you wire panels with different wattages the overall outcome won t be affected.
When connecting two or more solar panels in parallel you end up with less shading effect.
When your panels are connected in parallel you add the amperage together but the voltage stays the same.
The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage.
The biggest advantage to parallel rv solar panel wiring is that each panel is connected to every other component and if one 12v solar panel should for some reason experience a failure the other 12v solar panel will continue to produce solar power.
Connecting these panels in parallel will produce 200 watts 18 9v and 10 58 amps under optimum conditions.
If you answered yes to this question we would recommend connecting your panels in parallel.
