How to connect solar panels together.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. Firstly lets take a look at connecting solar panels in series. Just check a few things first. After these clarifications let s see how the series connection takes place.

Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together. 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. Solar panels are usually connected in series to obtain higher output 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.

There are two ways to wire up solar panels. By connecting multiple solar panels in series we increase the system voltage. It allows you to connect two panels then connect them into one solar input. You too can connect two solar panels into one system just like we do.

The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery. If we have two solar panels with the same voltage but different wattage there is no problem. Are the solar panels compatible. The best way to find out is to contact your solar panel supplier.

They can be wired in parallel. 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. 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.
