Mixing Different Voltage Solar Panels

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 different voltage solar panels.

Voltage in parallel you should be able to achieve a fair amoint of efficiency. 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. Since you are wanting to combine panels of differing currents but the same rated max.

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. If the panels are the same voltage and they both contain a diode to prevent reverse current then yes you can. 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. Typically the mixing of solar modules from different manufacturers and of dissimilar voltages wattages and amperages is not recommended.

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. 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.
