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.

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. 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. However if you take certain factors into careful consideration you can easily achieve this goal.

So they usually put a diode between the panel and the battery. 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. 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. 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.
