Mixing Different Voltage Solar Panels

This diode does lose about 5 percent of the power 5 volt drop so more with a 6 volt system less in a 24 volt 5 6 about 15 percent 5 24 about 2 percent.

Mixing different voltage solar panels.

Also read why solar power panels are necessary for you. Panel voltage is additive when panels are wired in series. Mixing solar panels of various voltage or wattage or produced by different manufacturers is a frequently asked question by most diyers. If the panels are the same voltage and they both contain a diode to prevent reverse current then yes you can.

Combining pv panels in series requires you to use panels with the same very close currents. The only way to wire in additional panels and guarantee that the voltage of all strings would remain equal is to add the exact same. When connecting different solar modules it s not the different wattage it s actually the current for series connection and voltage for parallel connection that could drag down the. Typically the mixing of solar modules from different manufacturers and of dissimilar voltages wattages and amperages is not recommended.

Since you are wanting to combine panels of differing currents but the same rated max. Voltage in parallel you should be able to achieve a fair amoint of efficiency. Mixing different solar panels in parallel maximum voltage on a string of modules must always be lower than maximum input dc voltage of the inverter.
