FAQs about 24V or 48V for solar power generation
Should I use 24V or 48V batteries for my solar system?
Most solar power systems would be better off jumping up to 48V batteries, rather than being limited by 24V batteries. If you're building an off-grid system that requires a little more power than you can achieve with 12V batteries, but not an overly huge output, a 24V system could fit the bill.
What is a 24V Solar System?
A 24V solar system can power a good amount of appliances and devices. When you pair this voltage up with a hefty wattage in solar panels, you're getting the real deal. The voltage in the name of the system can be characterized by any of the components, but in this case, we're going to refer to the batteries.
Should solar panels be 12V or 48V?
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.

How to calculate solar panel output voltage?
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
What is a typical open circuit voltage of a solar panel?
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
