Connecting Two Solar Panels In Series

When your panels are connected in series the operational voltage of the panels is added together.

Connecting two solar panels in series.

By connecting multiple solar panels in series we increase the system voltage. However the latter type of connection is at the expense of efficiency. Connection solar panels in series diagram first of all connect solar panel positive connection with other solar panel negative. 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.

Continue this process with all panels. If you are connecting two 100 watt panels in series and each panel has an output of 18 9 volts you will end up with 200w 37 8 volts and 5 29 amps under optimum conditions. In this case it is possible to wire the two 6v panels in series and then wire the resultant array in parallel to the 12v panel. When you wire in series there is just a single wire leading from the roof for each string of solar panels.

When you connect two or more solar panels like this it becomes a pv source circuit. If we have two or more solar panels with equal current and power and we want to increase the voltage the choice falls on the series connection. At this point any specific difference in voltages is not crucial voltages would simply add up and all you ve might need to judge is the fact that the total voltage must come within the inverter voltage limit. 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 installing solar panels in series the voltage adds up but the current stays the same for all of the elements. 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. Connecting solar panels in series the series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter.

Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. It is therefore essential before making a parallel connection to carefully check the voltage of the solar panels. There are some major benefits to connecting solar panels in series.
