Solar modules can be destroyed if they are exposed to extreme weather conditions, such as hailstorms.

Hails are meteorologically solid precipitation. They resemble ice and come in a variety of forms and sizes, up to half a pound in weight and as large as a baseball. The size variation determines how forcefully they fall.

When they fall, this decides the extent of their destruction. When thunderstorms occur and the airflow rises, large droplets of water are propelled upwards and into the atmosphere.

Do Hail Damage Solar Panels?

Evidence has proven that hailstones can significantly harm your solar panels in Colorado, where a few days a year appear a little like the end of the world with severe downpours and hailstones of various sizes.

Not even all solar panels are susceptible to hail damage, according to evidence. It is consequently critical that you make suitable inquiries about the type of solar panel you intend to get while planning your purchase. This also applies to people who have had their panels damaged and are considering replacing them.

Solar panels are extremely strong and resilient. Most high-quality hail can survive hail up to the size of a golf ball approximately, one inch in diameter. However, based on how much hail in your location and how huge the hail is when it strikes, the hailstones may cause significant problems to your solar panels during a severe hailstorm.

  • Your panels will be more prone to hail damage if they are positioned in front of an inclination less than this, say 10°.
  • Therefore, to prevent the natural route of hail, solar panels are commonly installed and mounted towards the south at angles of 18° to 45°.

3. Add A Layer Of Methacrylate To Your Panels

A very simple way is to apply a thin layer of methacrylate to protect the most fragile areas of the solar panels. This should be done as carefully as possible so as not to interfere with the proper functioning of the cells by blocking the access line to the power supply.

Coating the panels with an additional layer of “armor” may be a good idea as this plastic material reinforces the panels doubling the durability.

Finding the right methacrylate plates is indeed crucial because higher quality means solar panels will withstand more hits, which means less money spent. You can alternatively put a 1-inch thick piece of plexiglass on the base of the panel with the gap between the two levels. This is one of the most straightforward and secure methods for protecting solar panels from hail.

You will understand that your solar panels are safe not only against hail but also from a variety of other hazards.

4. Consider installing your solar panel in shaded areas

You may be wondering how solar panels would perform in locations that are shaded. Yes, new solar panels can operate in slightly shady places, protecting your panel from hail. All you have to do now is obtain the necessary information. We suspect that solar panels cannot function in the presence of shadows.

However, according to our findings, it is contingent on certain circumstances. Without a doubt, the colors of various items have an impact on electricity generation.

How To Protect Solar Panels From Hail?

Modern solar panels, on the other hand, can generate electricity even in the dark. You must be aware of the sources of shadow that can reduce energy use –

  • Tree

We discovered that plants block sunlight from reaching solar panel cells. It mostly occurs in residential areas. It can sometimes cast full or partial shade on solar panels.

  • Side by side panels

When it comes to ground installations, neighboring panels can create shadows on the lower panels. It occurs as a result of the system’s improper and unplanned installation.

  • Roofs

The earth revolves around the sun 24 hours a day, seven days a week. Building roofs gradually shade solar panels in the vicinity. It usually casts a partial shade on the solar cells.

5. Install Solar Cleaning Robots

Solar washing robots are a fantastic new technological advancement that uses only a minimal quantity of water to wash your solar panels of any possible hail particles.

You won’t have to worry about hail particles or stones damaging your solar panel thanks to the solar cleaning robots.

6. Regular Maintenance & Quality Checks

Solar panels are quite resilient, as previously stated. They will, however, be weakened by the wind or hail damage if they are not maintained regularly and they will eventually break if they are not maintained.

This is why you should inspect your solar panels regularly since this is one of the best ways to prevent them from hail damage, particularly if there are any indicators that they have been damaged.

7.  Follow Weather Forecast

Weathermen and forecasters can predict the arrival of hail, just as they can rainfall and other weather-related events. All you have to do is sign up for a few reliable websites that will keep you informed about hail storms before they happen. You can check if your solar panel is appropriately set or if it is in danger of being destroyed by hail with this update.

As a result, listening to weather tips and following the advice of weathermen will assist you in taking preventative steps against hail.

8. Install A Solar Panel Protection Cover

Solar panel protective covers are another option for shielding solar modules from hail. High-volume air is used inside hail prevention systems. A hail-protecting cover is most commonly used in automobiles. These solar module covers are also available for purchase.

The only issue is that these covers block sunlight, so you can’t use them all the time. Before covering your solar modules, you should have advanced knowledge of hailstorms or other inclement weather. If you keep track of weather forecasts, you can use them.
