How To Tie Solar Panels Together

If we have two solar panels with the same voltage but different wattage there is no problem.

How to tie solar panels together.

In this first image there are 3 solar panels. Couplers provide a nice easy way to wire up two solar panels say if you are wiring up for a little cabin or a boat or an rv. Initially you may find solar cells expensive so you may use them in conjunction with your existing grid power electricity to meet your home s energy requirements. Solar panel wiring aka stringing and how to string solar panels together is a fundamental topic for any solar installer.

This makes it possible to select an appropriate inverter for the array and make sure that the system. Solar power is increasingly gaining popularity as a reliable and clean energy source for the home. 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. 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.

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. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. You need to understand how different stringing configurations impact the voltage current and power of a solar array.
