24v battery photovoltaic panel voltage

24v battery photovoltaic panel voltage

For a 24 volt system the panel at max power rating needs to be 32 to 36 volts. Roughly 16 to 18 volts for every 12 volts of battery. However that rule only applies if you are using a standard PWM or shunt regulator. Using that type of regulator you will loose 30% minimum of the power from the panels.
