How To Hook Up Solar Panels In Series

When you connect two or more solar panels like this it becomes a pv source circuit.

How to hook up solar panels in series. Considering the example in the figure two 5a 12v panels wired in series produce a voltage of 24v and a current of 5a. Add up to combined power 150w 150w 150w 150w 600w. Connecting solar panels in parallel. When you wire in series there is just a single wire leading from the roof for each string of solar panels.

For photo voltaic components attached in parallel absolute power is determined as cited below. As clearly visible in the picture it is sufficient to wire the positive pole of one panel to the negative pole of the other and at the output we will find a doubling of the voltage. When a solar installer wires your solar panels in a series each panel is connected to the next in a string the total voltage of each solar panel is summed together but the amps of electrical current stay the same. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another.

Solar devices are normally attached in parallel to achieve greater output current. When installing solar panels in series the voltage adds up but the current stays the same for all of the elements. 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. Wiring solar panels in a series circuit connect the positive terminal of the first solar panel to the negative terminal of the next one.
