How To Connect 2 12v Solar Panels Together

Generally to achieve the 12vdc to 120 230vac system both pv panels and batteries are connected in parallel.

How to connect 2 12v solar panels together.

12v is the most common solar panel wiring connection with batteries. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. On the end of the string you need the 2mm tab wires protruding from the ends of the 2 strings you need to join. This will give you a parallel connection meaning the two panels will still give you the same voltage but twice the current.

To do so let s see how to wire two or more solar panels and batteries in parallel with solar charge controller and automatic inverter ups for 120 230v ac load battery charging and direct load i e. The battery is the only common denominator here. They might be for example one monocrystalline and one polycrystalline solar panel. Connecting 2 130w folding solar panel sets together welcome to the forum.

Wire the ve positive terminals together wire the ve negative terminals together. After these clarifications let s see how the series connection takes place. There are 3 ways to connect solar panels. As i stared before cells need to be connected front side to back side.

The picture above depicts the connection of two different 12v solar panels. Parallel series and a combination of parallel and series. 100w 18vmp x 5 5a imp and 50w 18vmp x 2 77 imp designated for a solar power system of a 12v system voltage. By connecting multiple solar panels in series we increase the system voltage.

In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. Now i will show how to connect 2 strings together. Connect to the device you want to power. Place the panels close to each other and oriented to the sun at the same angle check that the panels do not shade each other and that they are far from possible causes of shading choose an appropriate section of the electrical cable according to the distance of the panels use junction boxes to neatly wire the panel terminals together.

This type of connection is really efficient if the following conditions are met. Depending on the size of the panel you are building you will probably need to use short strings of cells to get all 36 cell connected. Answered july 18 2017.
