Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
The Bussmann range of PV surge protective devices (SPDs) provides complete system protection with PV ADVANCE to suppress lightning current and PV PRO or PV HEAVY DUTY to suppress overvoltage events. Together, they protect the DC voltage section of a PV system. Max.
In addition cables and inverter capacitance should be also considered. An Insulation monitoring device able to handle capacitance up to 500μF is suitable for PV system.

Over the last 50 years, solar PV systems have evolved into a mature, sustainable and adaptive technology. The unique nature of PV system power generation necessitates the need for new and effective electrical protection products for overcurrent, overvoltage and isolation events.
As the installations and demand for PV systems increases, so does the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors.
PV Cells are made from semi-conductor materials, such as polycrystalline silicon or thin film, that convert the sun’s light into DC electricity. PV Cells are connected in series to create a PV module and increase voltage. Figure 1: PV powered distribution network with NEC® defined circuits designated by arrows.
SPDs should always be installed upstream of the devices they are going to protect. NFPA 780 12.4.2.1 says that 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 .
