Protection against direct lightning strikes and transient overvoltage a lightning protection system for free field systems and solar parks has two main goals.
Lightning protection for solar power plants.
However lightning protection of solar arrays by traditional franklin rod systems is still subject to concerns regarding effectiveness shadow effects installation cost and appearance.
Try to route part of the system into wetter areas like where a roof drains or where plants are to be watered.
Lightning protection surge protection and comprehensive grounding engineering are a must when keeping power flowing to the grid.
Lightning protection is usually associated mainly with distribution networks or transmission lines and substations.
Solar panels are especially prone to lightning strikes due to their large surface area and placement in exposed locations such as on rooftops or ground mounted in open spaces.
Solar arrays are also electronic devices and so are subject to the same potential for damage from surges.
Direct strikes causing large ground step potential differences are hazardous to life and limb and to equipment.
Protecting the power plant area from lightning related damage protecting the modules inverters and monitoring systems from the effects of electromagnetic impulses.
Solar systems are often installed in open spaces away from.
Vfc and lyncole are proud to be the only company in the grounding industry that actively designs installs and verifies our utility and power generation lightning protection.
Solar pv systems in susceptible regions should be made safe from nature s power.
Solar lightning protection is important as lightning strikes and related electric discharge is one of the top reasons for sudden unexpected failures of solar systems.
Apart from direct strikes induction.
Undp flashage qxp layout 1 11 2 16 11 45 am page 1.
Earthing and lightning overvoltage protection for pv plants a guideline report november 2016 empowered lives.
Solar needs surge protection.
Lighting can seriously harm your pv system lightning strikes and related electric discharge are one of the top reasons for sudden unexpected failures of solar systems.
If there is steel well casing nearby you can use it as a ground rod make a strong bolted connection to the casing.
Lightning strikes are dangerous involving currents of up to several hundred thousand amps with rise and decay times of a few microseconds.
However another area in the electricity supply paradigm where application of arresters needs to be considered are relatively small power stations also known as distributed generation dg plants.
How to protect your solar power system from lightning.
Where solar arrays are installed on residential or other rooftops lightning protection as described in nfpa 780 chapter 12 is a useful reference.
There are 6 600 operating power plants in the u s.
