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.
According to NFPA 780 12.4.2.1, surge protection shall be provided on the dc output of the solar panel from positive to ground and negative to ground, at the combiner and recombiner box for multiple solar panels, and at the ac output of the inverter [6]. The proper installation of an SPD (Surge Protection Device) relies on three values:
Photovoltaic systems are vulnerable to both direct and indirect lightning strikes. Therefore, it is essential to build and install them with reliable surge protection. (References: [1] Lightning Protection Guide, DIN EN Standard 62305-3, 2014. [2])
