A single 100W panel can produce 20V (open circuit voltage), which is approximately 18V (optimum operating voltage), effectively charging a 12V battery bank, but not enough for a 24V battery. To charge this battery bank, you can either use a 24V (nominal) panel, or connect two smaller voltage panels in a series connection.
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.
Namely, we have to come to terms with the fact that there are several different voltages we are using for solar panels (don’t worry, all of these make sense, we’ll explain it). These solar panel voltages include: Nominal Voltage. This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels.
Previously, with 12V systems, that meant adding more panels, larger capacity charge controllers, and huge battery banks, plus all that beefy wiring. Now, many solar consumers with higher energy demands are moving away from 12V and toward 24V and 48V systems for overall cost-space-benefit.
