How to wire 2 solar panels in series.

When you connect the positive terminal of one panel to the negative terminal of another panel you create a series connection. When you connect two or more solar panels like this it becomes a pv source circuit. Just like a typical battery you may be familiar with solar panels have positive and negative terminals. When you wire in series there is just a single wire leading from the roof for each string.

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. If we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series.

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.

One positive and one negative. Just like a battery solar panels have two terminals. Moreover you can power up the dc load directly connected to the dc output terminals in the solar charge controller. Nonetheless it is possible to wire them in parallel.

The parallel connection allows to increase the current keeping the same voltage.
