How To Wire Solar Panels In Parallel Or Series

A parallel wiring connection is made by wiring the positive wires of two solar panels together and wiring the negative wires of each panel together.

How to wire solar panels in parallel or series.

For example if you installed 5 solar panels in series with each solar panel rated at 12 volts and 5 amps you d still have 5 amps but a full 60 volts. How do solar panels wired in series compare to solar panels wired in parallel. The actual amperage output gets the sum of the creation of each screen. To solve this problem and to optimize the energy performance of the entire system it is advisable to wire two panels in series obtaining a doubling of the voltage and then wire in parallel the three pairs previously wired in series so as to have doubled the voltage and tripled the current.

The branch connector has two inputs for the positive wires which join into one. The maximum voltage output of your solar array is limited only to what your controller can handle. The amps of electrical current for each solar panel are summed together but the system voltage stays the same. Connecting the panels is very straightforward.

When installing solar panels in series the voltage adds up but the current stays the same for all of the elements. A charge controller is a determining factor when it comes to solar panel wiring.

Inverters also have amperage limitations which you can meet by wiring your solar panels in parallel. Simply plug the positive of one panel to the negative of another and chain them together. To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below. If you wire the solar panels in parallel the total voltage result remains the same as it is in one panel.

Maximum power point tracking mppt charge controllers are for wiring solar panels in a series where pulse width modulation pwm charge controllers are used to wire solar panels in parallel.
