Solar panels face various weather conditions, including thunderstorms and lightning. What happens if lightning hits a solar panel? If lightning hits a solar panel in your house, it is said to cause much damage. It would likely cause damage to the panels and other solar PV cells and other solar PV equipment like the inverter, fuse, and cables. The tremendous energy from lightning can cause module failures, melt connectors, and potentially destroy the entire solar system. It’s important to recognize these risks and implement protective measures to safeguard your panels from lightning damage. In most cases, copper lightning arresters are used to protect the PV panel from lightning hits.
Researchers have studied devices you can install to protect your solar panels from lightning. Such devices can serve the purpose of protecting your system during stormy weather. They check to ensure that the materials and designs they use do not cause too much damage in case of an accident. For example, they examine grounding techniques that safely transfer electrical energy to Earth. Some researchers are also pursuing protective coatings that can reduce electrical effects under various conditions. These studies are used to improve the stability and safety of solar panels.
If you want to know what happens if lightning strikes a solar panel, then read the full article, it will be beneficial for you. The PV framework will keep on working. Call your insurance company first if you notice pool damage such as smoke or flames. Lightning can strike the panels, preventing the solar panels from being used.
Here are some tips that can help protect your panels. For example, recommend design and installation heights that reduce the risk of lightning strikes. They enhance solar panels for future installations with a balance of research and concrete solutions that make solar panels stable and safe.
How Many Types of Lightening Stroke?
A lightning arrester is an essential device that is used for protection or as a safeguard in the electrical substation, electrical power plant, power distribution station, solar thermal power plant, ground-mounted power plant, and others. However, we know that there are two main types of lightning strokes. Both direct and indirect lightning strikes are harmful. So, let’s see what happened in the direct stroke and indirect stroke of lightning.
Direct lightning strikes
Whenever direct electrical discharge occurs with light from the cloud to the earth’s surface or on any substance it is called a direct lightning stroke. It is a dangerous lightning strike for animals, plants, the human body, electrical power stations, and solar power plants or solar panels as well.
For this reason, in a power station or any electronic or electrical device that relates to producing electrical energy, surge arrestors are used for direct lightning stroke shielding of electrical substations. However, can you survive a direct lightning strike? Yes, humans can survive direct lightning strike injuries. In that case, home treatment is necessary with consciousness. So, don’t go outside during severe lightning.
However, direct strokes are rare, they’re hellish. It can destroy the whole system in one go if there is a direct lightning strike on your solar panels. Some of the solar components could melt out if such a stroke hit those portions of the solar panels. In addition, direct strikes can generate exceptionally high currents that could lead to overheating of system components.
Indirect Lightning Stroke
Indirect strikes are one the most form of strike types and indirect lightning strokes a quite less harmful as compared with direct strikes. They appear to generate electromagnetic inductions that translate into high voltages, in solar systems.
That high voltage can travel through the wiring to the components of the solar panel, causing damage to all those conductors as well that make up the solar system. So these are the symptoms of being indirectly struck by lightning. Moreover, the high voltage can produce sparks that might ignite combustible materials, causing fires. Sometimes this lightning can cause fire on PV plants. Though it’s a rare case but happens somewhere.
Do Solar Panels Attract Lightning Strikes?
Of course not. Photovoltaic panels do not attract lightning strikes but lightning can hit solar panels that can cause severe solar panel damage. For this reason, a surge protector is used to catch the lightning and send it to the ground to save PV panels. Those rooftop solar panels are a pretty choice for lightning for two reasons: Panels are located at least 10 feet above the earth’s surface and the PV panel frame is made of metal. Metal has good electrical conductivity.
For this reason, to avoid lightning stroke, a surge arrestor is used at the top of the solar panel that works like an umbrella that saves people from the rain. However, a common misconception is that metal objects, particularly tall ones like antennas, umbrellas, or other conductive materials, draw in lightning. This is not the case. Lightning can be attracted to a variety of materials, including water, rocks, soil, and trees.
Solar panels do not attract lightning. They are energized to discharge electricity rather than draw it in. Having solar panels mounted on metallic frames does not heighten the risk of a lightning strike. Solar panels do not present any extra risk when installed and grounded correctly. Proper grounding of the solar panel system can provide additional protection against potential lightning damage.
Height and Conductive Materials
Lightning stroke can happen at any place. In most cases, metal, highrise buildings, and high trees are the best choices to get attracted by surge stroke. Many times solar panels are installed at the tops of buildings or High Superstructure, making them potentially the highest objects in an area. They contain conductive materials (e.g. metal frames). But that doesn’t make them lightning rods.
Installation Environment
The risk increases if the system is located in an area that’s prone to frequent lightning storms. If poorly grounded, the electrical surges caused by nearby lightning may damage solar equipment. By grounding the solar array and structures properly, risks are reduced. Lightning arresters and surge protectors further protect the system.
Can Solar Panels Survive Lightning?
Solar panels are quite robust and can endure some electrical stress, directing lightning strikes to a lightning rod. Generally, the panels themselves are not the primary targets of lightning strikes, as their frames and mounts are mainly grounded. Rather, it’s the inverters and controllers that are more vulnerable. Proper grounding is vital for protecting your solar energy system from lightning strikes and any resulting damage.
Nonetheless, the powerful energy from a lightning bolt can potentially lead to the melting of microinverters or power optimizers within the panels. To reduce the likelihood of lightning damage hitting your solar array, you must make sure all its built-in protective and suppression measures are in place. This includes:
Grounding System
Make sure all the panel’s connections are grounded. If lightning strikes the photovoltaic panel then the grounding system can pass the heavy power to the ground and save the panel. So, secure the metal frames of the photovoltaic panels so that lightning can escape as needed.
Surge Protection Devices (SPDs)
In most cases, surge arrestors are located at the top of the buildings or solar panel system. However, use SPDs on both the AC and DC sides of the system to restrict any excessive voltage from affecting sensitive equipment. According to the lightning protection system, in prime areas for lightning, erect either a traditional lightning rod at the house itself or install a completely protective apparatus around the main fuse board.
Do Solar Panels Need to be Earthed?
Grounding solar panels is super important. You see, solar plants often encounter stray charges due to a bunch of different reasons like lightning strikes, the occasional exposed wiring, changes in weather, or even voltage fluctuations. For instance, imagine a scenario where the insulation material isn’t up to par. With a bit of humidity and heat, that stray current might skip the usual path and travel right through the panel frame instead.
This not only poses a risk to people but can also lead to issues like peak voltage induced in the solar panel modules. But here’s the good news: by grounding solar panels, we can transfer any heavy electrical current safely into the ground, where it won’t cause any trouble. This simple step helps keep everything running smoothly and safely.
Yes, it is essential to ground solar panels because stray charges are a common occurrence in solar plants. These charges can result from various factors, such as lightning strikes, exposed wiring, severe weather conditions, or fluctuations in voltage. For example, if a low-quality insulation material starts to deviate from its original busbar path.
It may instead travel through the panel frame due to conditions like humidity and heat. This can create significant hazards for individuals and lead to potential issues. Fortunately, by grounding a solar panel system, any unwanted electrical current can be safely channeled into the ground. More benefits of earthing are:
- The idea is that earthing protects people from electric shock and fire hazards as well. It also works as a safeguard equipment from damage caused by lightning (they usually have lightning, overvoltage, and electrostatic discharge.
- Earthing makes the solar system work safely and properly. It also helps to avoid electrical faults, which can affect solar system efficiency.
- Earthing can help the solar system last longer by protecting it.
What to do If Your Panels are Damaged by Lightning?
Solar panels usually suffer minor damage, When lightning strikes. Most of the time the system continues to function. Here are the steps you must take if panels are damaged by lightning:
- Check for smoke or fire: If there is a fire, Call your insurance company without fail.
- Evaluate the damage: If neither fire nor explosion occurred, now what happened to the solar panels?
- Decide if this is fixable: If it’s really bad, then get on the phone with those professionals who install equipment.
- Inform your insurance company: Look through policy terms to see if what’s happened is covered by lightning strikes on solar panels.
- Find a professional installer: If you don’t take care of the harm promptly, there’s a possibility that something else could go wrong.
What Signs Prove that Your Solar Panels Have Been Struck by Lightning?
Breakages, black scars on components, melted metal on parts, a decrease in electricity production, and inconsistent system performance are the signs that show that solar panels have been struck by lightning.
You can install surge protectors and lightning rods to defend your solar power setup against lightning. Lightning rods provide a path of low resistance to ground It is therefore less likely that lightning will penetrate your solar panel system. Also, surge protectors guide the lightning to earth; at the same time, they cut off high-voltage surges that might go anywhere else.
How to Avoid Damage from Lightning Stroke?
(1) During a thunderstorm, don’t stay on a high platform or close to exposed metal objects such as water pipes and electric equipment. Outdoors, don’t enter a hut in the open with neither doors nor windows or an isolated sentry box.
(2) Taking shelter from a thunderstorm beneath a tree is extremely dangerous. If needed, crouch about three meters away from the tree trunk to ensure you can safely get outside the tree.
(3) If during a thunder and lightning storm, you feel like ants are crawling all over your head, neck, and hands, and your hair stands up on end this is an ominous mail warning that lightning will strike. At this time be sure to lie down quickly. Do not forget your metal jewelry, time card, and chains that could conduct and increase your chances of being stuck.
(4) When the thunderstorm comes and there is no time to leave, find some dry insulation at once and put your feet on it. Do not place your feet outside the insulated object onto the ground which as water conducts electricity will transmit electric current right from the lightning bolt to you!
(5) When you hide from the thunderstorm outside, do not lift the ground with your hands. At once crouch down, with your hands around your knees, your chest as close to your knees as it can go. Also, keep your head down as far as possible since the head is the most likely to get hit in lightning strikes out of any part of the body.
(6) When you are out and hear thunder, it means that you are under threat from the storm. At this moment you should stop walking and lie down immediately. Better still use plastic rain gear, such as a raincoat.
(7) In a thunderstorm, also it is very dangerous to walk with an umbrella or hold up a badminton racket, golf clubs, hoes, etc. as they can indeed become electric conductors. On top of the implications for weather, it’s not suitable to play ball outdoors. Indeed washing clothes there, fishing in rivers, swimming in lakes rivers, and playing riverside all may be full of imminent dangers.
(8) In the thunderstorm, don’t try driving a motorcycle on a bike or running in the rain. That is because the larger one’s stride is, the more voltage goes through their body.
Do Fuses and Breakers Protect Me From Lightning Strikes?
Fuses and circuit breakers don’t offer enough protection devices require an amperage of 15-20 to break the circuit, which is more than enough power to kill in an instant.
Lightning protection is a must: One tripbreaker isn’t going to save you from a bolt of lightning. You’ll need a complete protective system to safeguard the entire house.
Unplug equipment: The safest way to protect your devices during a thunderstorm is to turn them all off.
Turn off circuit breakers: Before the storm arrives, switch off the circuit breaker in your home and thereby avoid power surges that could damage electronic components
Install lightning rods: Lightning rods and their related protection system are intended to protect your home from direct lightning bolts.
What Happens if Lightning Hits a Solar Panel?
Solar panels are extremely dangerous when hit by lightning. If a panel on a piece of solar equipment is struck by lightning, the panel could be melted or the electronics also burned out. Even if it does not strike an actual lightning will still arc from nearby trees or objects and attack your system.
To protect your panels, be certain they are properly grounded and that you use surge protection devices if needed. Also, it is safe-proof with an entire residential lightning protection system.
1. Fire Hazard
While solar power generation is a way of generating power, the risk of fire exists in solar installations that are not properly installed and maintained. Electrical malfunctions and fire from wiring that was not up to standard, damaged components, or lightning strikes led to 68 cases of fires worldwide last year.
If you want to minimize your chances of having an accident from putting up solar panels on your home, please find a contractor who has built at least 50 systems (and has installed and maintained them too), make sure you maintain your system now and then, and have someone besides yourself look after it.
2. Occur Sparking
- When electricity jumps from one place to another it sparks. This jump makes not only a bright light but also a loud noise.
- High voltage is often the problem. Loose wires too can cause it. Even little static can bring about such a jump. Have you ever seen lightning? That is the thing itself making a big jump in the sky.
- It is hazardous for electricity to make these jumps it can produce fires. So look out for a proper solution.
3. Damage Solar Panel or Inverter
Solar panels and inverters are susceptible to damage, with hail and wind as well as falling debris all threatening their integrity. Conversely, they are just as vulnerable to extreme temperatures, which can easily damage both of them.
4. Plumbing Damage
Solar plumbing or mounting systems play a crucial role in standing up PV panels. Inverters in a solar system can easily overheat, get hit by lightning, and become waterlogged. To keep them safe, wash them often and with a nice quality part.
5. Interrupt Energy Generation
Energy generation can be interrupted by many factors. Bad weather, such as storms or strong winds, might break the power lines. Equipment breakdowns can also cause power outages. Sometimes, maintenance work must be carried out, temporarily halting power generation. Power companies are working hard to prevent outages as they try to keep equipment and plan for emergencies.
Conclusion
What Happens if Lightning Hits a Solar Panel? Lightning can severely damage solar panels and other equipment. When lightning strikes, it can ignite the panels, burn electronics, or cause nearby electricity to arc, hurting the system. If wiring or components are damaged, a fire could also break out. Loose wires, unstable connectors, and high-voltage sparks could lead to fire. Lightning, severe weather, or debris can damage solar modules and inverters.
Ordinary household lighting can also damage plumbing systems and equipment that overheats due to long hours of operation. Lightning rods, surge protectors, and grounding should be used on your system to reduce the risk from weather influences, for instance. It is important to install well and maintain regularly. This can also avoid accidents. Lightning protection ensures that your solar setup can withstand a storm and still operate well.
