Solar Panel In Series Connection

Wiring your solar array in series increases the voltage to the sum of all the panels.

Solar panel in series connection.

The current will go down which means you can push more power through the same size wire more on this in a moment. Continue this process with all panels. In last you will find out that you have negative wire free form you first solar panel and positive from you last panel. In a solar power system the higher the voltage and the lower the energy losses along the cables.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. Wiring solar panels in series. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. 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.

When you wire in series there is just a single wire leading from the roof for each string of solar panels. 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. This makes for better efficiency but an mppt charge controller is required to convert your solar array voltage to 12 volts on your battery. When installing solar panels in series the voltage adds up but the current stays the same for all of the elements.

By connecting multiple solar panels in series we increase the system voltage.
