Continuing up to the top left panel there will be 12 volts in and coming out with 18 volts.

How to connect a second solar panel.

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. If both panels are rated at the same maximum voltage then you ll get maximum output. To do this we connect the positive side of the first panel to the negative side of the second panel.

In this video i show how i added a second solar to my existi. Join me on my adventures. 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. Maximum rated current 5 8a.

Connecting two solar panels in parallel. My name is brian. There will now be 12 volts coming out of this second panel. Connect the negatives to the negatives and positives to the positives.

If your existing solar panel is 100 watts and you want to add a 50 watt solar panel you will need a charge controller that can handle 150 watts plus 10. For example our 115w sunpower solar blanket has the following ratings. I am living on the road in my self built camper van. Maximum rated voltage 19 8v.

They can be wired in parallel. Your charge controller has to be able to handle at least 10 more than this.
