How To Wire 2 Solar Panels Together

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

How to wire 2 solar panels together.

After these clarifications let s see how the series connection takes place. Firstly lets take a look at connecting solar panels in series. Wiring solar panels in a parallel circuit. 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.

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. There are two ways to wire up solar panels. By connecting multiple solar panels in series we increase the system voltage. We put solar panels together to increase the solar generated power.

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. When you intend to wire two panels produced by different vendors the vendors are not the problem. If we have two solar panels with same voltage and power the connection will be very simple. Solar panels are usually connected in series to obtain higher output voltage.

The problem is in different electrical characteristics of the panels together with different performance degradation. 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. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage 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.
