Grouped

Solar panels are grouped in the same way but with different voltages

When your panels have the same current but different voltage, you need to wire your panels in series. 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. . Meta Description: Discover how grouping photovoltaic panels with different voltages boosts solar energy efficiency. Why Voltage Diversity Matters in Photovoltaic Panel Grouping Photovoltaic (PV) panels. . Does anyone know if you can use a string of panels of say 48 volts and another string of 24 volts into a combiner box then into a charge controller? Or do they all have to be the same voltage. you can but there is a penalty. Let me explain it. For the best results, use identical solar panels across the array.
