There is no doubt that solar energy is revolutionizing the energy landscape. Thanks to it, thousands of people and companies can have self-consumption and reduce their environmental impact. However, there are some risks associated with the durability of solar panels and their conservation in optimal conditions. We are talking about the solar panels and hailOne of the most common doubts among people who install solar panels is whether hail can destroy them.
In this article, we're going to tell you everything you need to know about solar panels and hail, from the risks to weather resistance, as well as ways you can protect your photovoltaic system.
Solar panels and hail: How does it affect you?
One of the biggest concerns for solar panel users is their longevity and resistance to adverse weather conditions, such as hail. Although solar panels are designed to withstand the elements, the impact of very large hail can cause damage.
The main problem related to hail is usually the appearance of microcracks on the surface of silicon crystalsThese cracks can occur during manufacturing, transportation or installation, but are most often caused by prolonged exposure to sudden temperature changes or severe weather impacts. Microcracks can lead to a gradual loss of efficiency over the long term.
Under normal conditions, solar panels are built to withstand small to medium-sized hail, but if the hail is golf ball-sized or larger, it could damage the glass on your panels, affecting their performance or even breaking them.
Are there any anti-hail solar panels?
The key to protecting photovoltaic panels from the impact of hail is to choose panels with appropriate certificationsIn Europe and other parts of the world, many solar panels are certified under the IEC 61215 standard, which ensures that the modules can withstand harsh environmental conditions, including hail storms.
To prove their strength, solar panels must pass an impact test in which they are thrown 203 gram ice disks at a speed of 39,5 m/s to the panels. In general, panels that meet this certification have a damage index less than 5%, which guarantees considerable resistance.
These days, finding hail-resistant solar panels isn't difficult. Most reputable manufacturers pass weather resilience tests without any issues. However, it's crucial to make sure your modules meet international regulations and specific hailstorm resistance tests before installation.
Do warranties cover hail damage?
A recurring question is whether the warranties provided by manufacturers cover damage caused by hail. In most cases, the solar panel warranty covers manufacturing defects, such as solar cell failures or a significant decrease in production capacity (typically below 80% of its original capacity for the first 10 years).
However, many manufacturers exclude certain types of damage from their coverage, such as those caused by natural disasters including storms, lightning, hurricanes, or extreme hail. For this reason, it is essential to read the warranty conditions carefully before choosing a solar panel.
In some cases, home insurance may cover this damage. Many policies include the option to add coverage for solar panel systems as part of the home contents. Be sure to talk to your insurer about including additional protection for extreme weather events.
How to protect solar panels from hail
If you live in a region prone to severe storms, you may want to take additional steps to protect your solar installation. Below are some strategies that can reduce the risk of damage to your panels:
Use reinforced panels
Consult your installer about the choice of Photovoltaic panels with reinforced frameThis option is ideal for areas with frequent or intense hailstorms, as it improves the overall resistance of the panel to impacts and additional loads, such as accumulated snow.
Additional protection with mesh
An option to further protect solar panels is to install protective meshes above the panels. These meshes help to absorb the impact of hail before it reaches the panel surface, reducing the likelihood of breakage or cracking.
Hire a maintenance technician
A periodic inspection by a specialized technician is crucial. They will inspect the structure and electrical components, allowing them to identify possible minor damages before they become serious problems. This type of maintenance can extend the life of your solar panels.
Insurance for solar panels
Make sure your solar panels are protected by a adequate insuranceMany home insurance policies include coverage for possible hail damage as part of the building insurance, but it is advisable to confirm this with your insurer.
Finally, remember that the risk hail poses to solar panels depends on many factors, including the size and frequency of the hail and the quality of the panels. While in most cases damage is minor or almost non-existent, it is important to be prepared and take preventative measures when necessary.
Solar panels are an excellent option for generating clean energy and reducing electricity costs. However, hail can be a risk in certain areas. With the right information and by taking the necessary measures, you can ensure that your investment is protected for many years to come.
