![]() In this example, our series string will have some power losses because the currents of the 12V/8A panel and 14V/7A panel will get "pulled down" to 6 amps. When wired in series, the resulting series string will have a voltage of 42 volts (12V + 14V + 16V) and a current of 6 amps (the lowest current rating of the 3 panels). Different Solar Panelsįor mismatched solar panel wired in series, the voltages are summed and the current is equal to that of the lowest-rated panel.įor example, let's say you have 3 different solar panels with the following specs: In this example, the series string will have no losses. When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps. All have a voltage of 12 volts and a current of 8 amps. Series Identical Solar Panelsįor identical solar panels wired in series, the voltages are summed and the current stays the same.įor example, let's say you have 3 identical solar panels. Here's how to calculate the power output of your solar array, regardless of how you're wiring your panels together - and regardless of whether or not the panels are identical. How to Calculate Solar Panel Output of Series & Parallel Wiring Configurations For that, check out our solar panel voltage calculator. ![]()
