How To Wire Two Solar Panels Together

There are two ways to wire up solar panels.

How to wire two solar panels together.

The following wiring diagram shows that the two 12v 10a 120w solar panels connected in parallel will charge the two 12v 100ah parallel connected batteries as well as power up the ac load through batteries and inverter during the day in normal sunshine. Wiring solar panels in a parallel circuit. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together. The video will go over the basic installation and can apply directl.

Firstly lets take a look at connecting solar panels in series. If you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps the entire array would be 12 volts at 20 amps. We put solar panels together to increase the solar generated power. When you intend to wire two panels produced by different vendors the vendors are not the problem.

Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. The problem is in different electrical characteristics of the panels together with different performance degradation.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. Solar panels are usually connected in series to obtain higher output voltage. If we have two solar panels with same voltage and power the connection will be very simple.
