This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
In solar photovoltaic (PV) systems, the voltage output of the PV panels typically falls in the range of 12 to 24 volts. However, the total voltage output of the solar panel array can vary based on the number of modules connected in series.
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.
The output voltage of a solar panel is determined by the number of solar cells wired together into a single panel. High voltage solar panels have more cells connected and are more efficient than low voltage panels. They also require less space to deploy, reducing the cost of materials and labor for mounting on a roof or ground mount.
Nominal voltage is an approximate solar panel voltage that can help you match equipment. The voltage is usually based on the nominal voltages of appliances connected to the solar panel, including but not limited to inverters, batteries, charge controllers, loads, and other solar panels.
High voltage solar panels are more efficient than low voltage panels and require less space to deploy, which reduces the cost of materials and labor for mounting them on a roof or ground mount. High voltage panels require thinner copper wire to connect the array, the charge controller, and the battery bank.
Ultimate Guide to Solar Panel Voltage
An average 12V solar panel can generate somewhere around 17 volts. However, it''s worth noting that the output voltage is affected by multiple factors. Understanding the solar panel voltage will help you design your own PV system for safely charging all your electrical appliances.
