Solar Panels Lightning Protection

The panels are not usually the biggest victim of lightning strikes as frames and mounts on panels are usually grounded. Proper grounding is essential for protecting your solar energy system against lightning strikes and damage.

A damaging surge can occur from lightning that strikes a long distance from the system or even between clouds.

Solar panels lightning protection. Protecting the power plant area from lightning related damage protecting the modules inverters and monitoring systems from the effects of electromagnetic impulses. How to protect your solar power system from lightning lightning is a common cause of failures in photovoltaic pv and wind electric systems. First make sure there is a lightning arresting system completely separate from the pv system designed to attract lightning strikes and shunt them to ground.

So lightning protection is a two part process. Lightning is the number one cause of catastrophic failures in solar electric systems and components. Solar needs surge protection.

Protection against direct lightning strikes and transient overvoltage a lightning protection system for free field systems and solar parks has two main goals. Solar arrays are also electronic devices and so are subject to the same potential for damage from surges. Lightning can cause devastating damage to solar panels and protection needs to be considered during the design stages.

Lightning and surge protection for solar panels. Lightning strikes whether direct or indirect can result in both down time and expenses in identifying and replacing damaged parts. The first major reason is that many pv systems are poorly grounded and poorly protected.

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. The inverters and controllers are. This is where the short fat and straight part comes in for all those conductors.

The first thing to consider is how likely a lighting strike is. Lightning and related static discharge is the number one cause of sudden unexpected failures in pv systemslightning does not have to strike directly to cause damage to sensitive electronic equipment such as inverters controls radios and entertainment equipmentit can be miles away and invisible and still induce high voltage surges in wiring especially in long lines. Your solar power system can be damaged by direct strikes or more likely voltages induced by nearby lightning strikes.

That is also the 2nd and 3rd major reason. If you want to protect your solar power system solar panels and solar inverter from lightning that is possible but it will cost extra. Raycap is a leading producer of surge protection devices for photovoltaic pv systems that are used in both industrial power production as well as residential or semi commercial markets.
