Mixing Different Voltage Solar Panels

If the panels are the same voltage and they both contain a diode to prevent reverse current then yes you can.

Mixing different voltage solar panels.

Also read why solar power panels are necessary for you. 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. Mixing solar panels of various voltage or wattage or produced by different manufacturers is a frequently asked question by most diyers. 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. So they usually put a diode between the panel and the battery. However if you take certain factors into careful consideration you can easily achieve this goal. Combining pv panels in series requires you to use panels with the same very close currents.

Panel voltage is additive when panels are wired in series. 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. Since you are wanting to combine panels of differing currents but the same rated max.
