Technical FAQs 4

What does voltage mean on a solar panel?

Voltage is like water pressure in a pipe. Just as too much water pressure can burst a pipe, too much voltage can damage your power station. Here's what you need to know about voltage for solar panels: Open Circuit Voltage (Voc): This is the maximum voltage your panel can produce, usually measured on a bright, cold morning.

What happens if a DC voltage is increased?

If the DC system voltage is increased, the DC current will drop, and the cables can be thinner. If you want to increase the system voltage, but there are DC loads or DC charge sources that only can deal with 12V, you could consider using DC-DC converters rather than choosing a low voltage for the entire system.

What is the difference between voltage and current for solar panels?

Maximum Power Voltage (Vmp): This is the voltage at which your panel operates most efficiently. If voltage is pressure, current (measured in amps) is the flow rate. Voltage is how steep the river is, while current is how much water flows past you each second. Some key points about current for solar panels:

How does a DC Circuit work?

A DC circuit usually contains a main battery fuse, after which it branches off to the individual consumers. Each consumer has an individual fuse. The circuit breakers are located near the entry point of the public grid and/or the generator into the switchboard.
