Mixing Different Voltage Solar Panels

Voltage in parallel you should be able to achieve a fair amoint of efficiency.

Mixing different voltage solar panels.

Panel voltage is additive when panels are wired in series. Combining pv panels in series requires you to use panels with the same very close currents. 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. So they usually put a diode between the panel and the battery.

Also read why solar power panels are necessary for you. Typically the mixing of solar modules from different manufacturers and of dissimilar voltages wattages and amperages is not recommended. Mixing solar panels of various voltage or wattage or produced by different manufacturers is a frequently asked question by most diyers. 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.

Though mixing different solar panels is not recommended it s not forbidden and things would be ok as long as each panel s electrical parameters voltage wattage amps are carefully considered. 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. Since you are wanting to combine panels of differing currents but the same rated max.
