Bring a multimeter and set it to DC Voltage measurement.
What is a 12V solar panel rated voltage?
The rated terminal voltage of a typical 12V solar panel is around 17V, this voltage is further regulated by a solar charge controller around 13 to 15 Volts to charge batteries. Sometimes solar panels produce overvoltage due to various factors that can be harmful to the solar power system.
How to reduce the voltage of a solar panel?
Solar panels are connected in two-part wired series to get more voltage out of them. However, if solar panels are producing too much voltage then making the connection parallel can reduce the voltage. This can be done by making some changes to the junction box. This method is not easy and should be done by an expert solar technician.
Why are solar panels connected in series?
Solar panels are connected in series to increase and meet the desired solar system voltage. If solar panels connected in series are more than recommended then they will produce too much voltage. For example, if one 12V battery is connected to the solar inverter, it will require a single 12V solar panel to provide around 17V.
