Severe Weather Resistant

What are the Extreme Weather Conditions that Solar Panels Can Face?

Exetreme weather conditions are in every place in the world but it differs what kind of weather conditions occur in each place will be different. For Example, in America Weather conditions could start from snow to tornados or even extreme hails on the other hand in Europe & Russia there is a lot of snow that can put a lot of loads on the solar panels. If we go to Africa & the middle east, we have sand storms and extreme temperatures that can cause a lot of stress on solar panels & their ability to produce a suitable amount of power.

How Each Extreme Weather Condition Can Affect Solar Panels?

  • 1-Extreme Temperatures: In some places like the Middle East temperatures can achieve 50℃ which causes a huge drop in power output due to the temperature coefficient of solar panels.
  • 2-Humidity and freezing: strong humidity & the freezing of water on top & bottom of the panel make cells contract and then expand could lead to cracks on solar cells that will result in power degradation over time.
  • 3-Heavy Winds: Wind loads can cause the solar panel to be misplaced or break its mounting structure which can cause losing a whole solar power plant due to these types of winds.
  • 4-Heavy snowfall: Heavy Snowfall applies a large amount of load on top of the solar panel making it pressure the glass which can cause a failure of the mounting structure supporting such high weights.
  • 5-Hail: frozen rain drops that hit solar panels’ surface frequently & in large amounts making it can cause the break of solar panel glass.
  • 6-Sand storms: Sand storms have a lot of sand particles that rotate or move at very high-speed making it damaging the solar panel glass & mounting structure which can cause the destruction of a solar power plant.

What is the single worst weather condition that causes damage to solar panel statistically?

There are several weather conditions that can cause damage to solar panels, but the one that is considered the worst and most likely to cause damage is hail. Hail can cause physical damage to the panels, such as cracks or dents in the tempered glass, and can also damage the underlying solar cells and other components. Hail storms can be particularly severe in certain regions and are known to cause significant damage to solar panels. Other weather conditions that can cause damage to solar panels include high winds, heavy snow loads, and extreme temperatures. Additionally, lightning strikes can also cause damage to the solar panels, inverters and other components of the solar power system.

How to Achieve Extreme Weather Resistance for Solar Panels?

Manufacturers are currently adding different layers of protection to solar panel glass to prevent it from getting damaged by any of the above weather conditions. While also using a stronger mounting structure that can withstand weight & other pressures caused by different weather conditions.
The technologies and materials that make solar modules extremely weather resistant include:
  1. Reinforced aluminum frames: The frames of solar modules are typically made from aluminum or other durable materials that can withstand high winds and heavy snow loads without bending or breaking.
  2. Tempered glass: Solar modules use tempered glass, which is stronger and more durable than regular glass. It can withstand impacts and extreme temperature changes without breaking.
  3. UV-resistant materials: Extreme weather-resistant solar modules are made with UV-resistant materials that can withstand prolonged exposure to the sun's ultraviolet (UV) rays without degrading or yellowing.
  4. EVA (Ethylene-vinyl acetate) Encapsulant: This material is used to seal and protect solar cells and other components of the module. It is resistant to water, dust, and UV rays.
  5. Back sheet: The backsheet is the layer in the module that is in contact with the rear side of the solar cells and the frame. A backsheet made of TPT (Tedlar-polyester-Tedlar) or ETFE (ethylene tetrafluoroethylene) is used to protect the module from moisture and UV rays.
  6. Junction Box: A weatherproof junction box is used to protect the electrical connections of the module from moisture and dust.
  7. Certifications: Manufacturers may also certify their solar modules to industry standards that have been developed to test their ability to withstand extreme weather conditions.
  These materials and technologies are designed to withstand harsh environmental conditions such as high winds, heavy snow loads, and extreme temperatures, ensuring that solar modules can continue to generate electricity even in extreme weather conditions.
