How do photovoltaic cells work?

The photovoltaic cells utilise the power of sunlight to convert photons to clean DC (Direct Current) electricity. The Electricity generated by the Solar Cells is then fed into a Power Inverter (PV inverter) that converts and regulates the DC source into usable AC (Alternate Current) power.

What is the overvoltage of a PV system?

The overvoltage depends on the setup conditions of each PV system and the wirings. The maximum voltage a PV system can experience over and above its nominal voltage is a factor that needs consideration in surge protection for photovoltaic systems. PV systems are exposed in large open spaces, typically in fields or on the tops of buildings. Charged rain clouds that accumulate over such open fields have the propensity to release the charge in the form of lightning.
