How Do You Connect Solar Panels Together

When you are looking to connect solar panels produced by different manufacturers together the problem does not come from different manufacturing styles or cell type it comes from the electrical characteristics of the solar panels.

How do you connect solar panels together.

There are 3 ways to connect solar panels. Three panels of 12v and 3a and one panel of 9v and 1a. 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. It allows you to connect two panels then connect them into one solar input.

For this example i am showing you connecting panels that are for a 12 volt system. However if you are switching entirely to the solar power you will have to purchase and install batteries that store the solar power for use at night. If we have two solar panels with the same voltage but different wattage there is no problem. Wiring solar panels in a parallel circuit.

Consider having a set of four solar panels. Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array which are to be connected to the input either of the inverter in case of a grid tied system without a battery backup or the charge controller in case of a grid tied system.

Ptot p1 p2 p3 p4 9v 3a 3a 3a 1a 90w. 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. You too can connect two solar panels into one system just like we do. Step 3 connect the solar panels either directly to a power inverter and then connect it to the home grid or connect the inverter to the battery and then to the home power grid.

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. If you connect these four panels in parallel all of them must have the same voltage and therefore will generate at the maximum possible voltage for one of the panels which means 9v. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.
