In this article, I will talk about installing a surge protection device for solar panels. You size the surge protection device according to the voltage of your solar array, whether its wired in series or parallel. Let's say the combined voltage of your solar array is 500VDC; then, you need to get an SPD rated at 500VDC.
A solar SPD is a surge protection device that is specifically designed for use in a solar power system and its components. Solar surge protection devices essentially divert any excess voltage that is produced by a lightning strike or other voltage spike, protecting the solar installation from damage.
PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors. Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future.
This type of SPD cannot be used on the DC side of the system as it is only designed to work with AC voltage. A solar DC surge protection device is connected to the DC side of the solar power installation, between the inverter and the array or panels.
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.
