How To Wire Two Solar Panels Together

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.

How to wire two solar panels together.

The problem is in different electrical characteristics of the panels together with different performance degradation. During shading night when there is no generating power from solar panels the battery stored energy will be used as a backup power and it. There are two ways to wire up solar panels. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together.

To have a functional solar pv system you need to wire the panels together to create an electrical circuit through which current will flow and you also need to wire the panels to the inverter that will convert the dc power produced by the panels to ac power that can be used in your home and sent to the grid. Solar panels are usually connected in series to obtain higher output voltage. This is the first part of our video on how to connect your panels in series and parallel. When you intend to wire two panels produced by different vendors the vendors are not the problem.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. We put solar panels together to increase the solar generated power. 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. If we have two solar panels with same voltage and power the connection will be very simple.

Wiring solar panels in a parallel circuit. 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. 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.
