Solar panels are an excellent investment for the energy self-consumption, but their exposure to the climate makes them vulnerable to extreme weather events. These include: hailstorms They pose a considerable threat as they can cause microcracks, breakages or even render photovoltaic modules unusable in extreme cases.
While the panels are designed to withstand inclement weather, the climate change has increased the frequency and intensity of hail storms, increasing the risk of damage. Fortunately, there are various protection measures and prevention that can ensure the durability of your solar installation.
Can solar panels withstand hail?
Solar panel manufacturers subject their products to strict resistance tests, including hail impacts according to regulations. IEC 61215In these tests, the modules must withstand the impact of ice balls of up to 4 diameter cm launched at speeds greater than 100 km/h.
Despite these certifications, not all panels have the same level of resistance. Models with tempered glass are more robust, while those with poorly reinforced frames or less resistant materials may be more vulnerable to strong impacts.
Factors that determine hail damage
There are several factors that influence the likelihood of a solar panel being damaged by a hail storm:
- Hail size and speed: The larger the ice stones and the higher their impact velocity, the more likely there is to be breaks or cracks on the surface of the panel.
- Installation angle: Tilted plates tend to receive impacts with less force than those that are installed in a completely horizontal position.
- Glass quality: Solar panels with tempered glass and greater thickness offer greater resistance to intense impacts.
- Geographic location: In regions with frequent strong storms and hail, the risk of damage to solar panels is significantly higher.
How to protect solar panels from hail
Implement protection measures can make the difference between an intact photovoltaic installation and one that needs costly repairs. Here are some key tips:
Choose high-strength panels
If you live in a storm-prone area, consider installing panels with tempered glass. greater thickness or with advanced hail resistance certifications. Models such as the FuturaSun Rhino or the panels REC They have a reinforced design to withstand more aggressive impacts.
Install protective covers
There are solutions such as transparent covers of polycarbonate or protective nets that can cushion the impact of hail without affecting the energy production of the panels.
Strategic orientation
To the extent possible, installing the panels with an appropriate inclination can reduce the force of the hail impact. 30 degree angle can help minimize the effects of ice chips.
Take out insurance
Many home insurance policies can cover damage to solar panels, but it is important to check the specific conditions of the policy. It is advisable to take out insurance that covers hail, storms and other weather phenomena.
What to do if your solar panels suffer hail damage
If you notice damage to your solar panels after a severe storm, follow these steps:
- Visually inspect the panels: Look for cracks, breaks or obvious signs of damage.
- Check with your insurance: If you have a policy that covers hail damage, contact your insurer to begin the claim process.
- Request a technical review: A professional will be able to determine if the damage affects the efficiency of the installation and if it is necessary to repair or replace the affected modules.
- Avoid electrical risks: In case of severe damage, it is advisable to shut down the installation until a technical assessment is carried out.
Guarantee the protección Protecting your solar panels from weather events like hail is an investment in safety and durability. While modern solar panels are designed to be resilient, taking preventative measures can prevent costly replacements and extend their lifespan. With proper material choices, strategic guidance, and adequate insurance coverage, you can enjoy the benefits of solar energy without worrying about harsh weather.
