4 FAQs about What to do if the photovoltaic panel voltage exceeds the limit

How to fix overvoltage problem in a solar system?

The first step to fix the overvoltage problem in a solar system starts with the checking of its solar panel's voltage by performing an Open Circuit Voltage Test as per the below-given instructions: Direct the solar panels towards the sun during peak sunlight hours. Bring a multimeter and set it to DC Voltage measurement.

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.

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.

Can I upgrade my solar panel from 12V to 24V?

Use only compatible solar panels whose rated voltage matches the battery voltage. However, when you are upgrading your solar power system from 12V to 24V, then you have two choices: either replace the 12V solar panel with a 24V solar panel or add another 12V solar panel in series.
