Mixing Different Voltage Solar Panels

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.

Mixing different voltage solar panels.

Panel voltage is additive when panels are wired in series. 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. So they usually put a diode between the panel and the battery.

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

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