How To Tie Solar Panels Together

Stringing solar panels in series involves connecting each panel to the next in a line as illustrated in the left side of the diagram above.

How to tie solar panels together.

In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires. 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 with a battery backup or off grid solar panel system. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. You will see a symbol that looks like a triangle pointing down at a horizontal line.

You simply need to do some research and purchase a controller that is capable of handling both systems. You do not want to wire more than 2 panels in parallel using couplers because this does not give you over current protection between the two panels. Wind generators and solar panels can be hooked up together through the same wiring system. The solar panels are usually designed that they can handle being backfed from one panel but if you have a whole bunch you do run the risk of ruining your solar panel.

If we have two solar panels with same voltage and power the connection will be very simple. The clips should hold the wires in place during strong winds. The set up is fairly straightforward and will vary slightly based on the individual energy systems that you are using. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller.

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. 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. When solar panels are wired in parallel the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together. Do not allow exposed wiring to make contact with the roof surface.

The red line is the positive connection to the panels. Wire the solar panel. Connecting solar panels in series. Use cable clips to secure wiring from solar panels and micro inverters power optimizers.

This power inverter converts the solar energy into energy that is consumable at home.
