Surge Protection for Solar Tracker System
OVERVIEW
Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Surge Protection for Photovoltaic System or/and Solar Tracker System. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.
This article discusses the various aspects of Photovoltaic Systems or/and Solar Tracker Systems to help you develop a comprehensive surge mitigation strategy for your equipment. Each section will conclude with a Surge Protective Device (SPD) Protection Point which identifies where and what SPD to use.

Photovoltaic Power Plant
Photovoltaic power plant is exposed to the environment, induced surges via lighting, and switching transients by way of switching from the substation. Any damage or down time to equipment operating within the solar array directly affects the output of the solar farm.
