Every now and then, nature flexes her muscles, reminding us of the tremendous force she can wield. From hurricanes to hailstorms, our technologies are put to the test. As this technology continues to permeate our lives, a recurring question keeps cropping up: Can Solar Panels Withstand Hail?
Yes, they can! Manufactured to weather the elements, modern solar panels are a marvel of engineering. They’re designed to take a licking and keep on ticking. They can withstand more than just a light drizzle. Hail? You’d be surprised at the beating these panels can endure.
But there are some caveats to that. Let’s delve deeper and demystify this crucial concern.
The Anatomy of a Solar Panel
A solar panel isn’t just a flat, gleaming slab; it’s a technological marvel with multiple layers, each serving a distinct purpose.
The Solar Cell
At the heart of each solar panel are the solar cells, also known as photovoltaic cells. These are typically made from silicon, a semi-conductive material.
When sunlight hits these cells, it shakes electrons loose from their atomic orbits, which generates an electric current. This is the fundamental principle of solar energy conversion.
A network of metallic strips, or busbars, transports the electric current from the cells to the solar panel’s junction box.
From there, the electricity flows through an inverter which transforms the direct current (DC) into alternating current (AC) for use in your home or business.
The Panel Casing
Wrapping around the panel like a sturdy frame is the panel casing, usually constructed from robust, corrosion-resistant aluminum.
This casing provides essential structural support and houses drainage holes to prevent water buildup, protecting the delicate solar cells from the elements.
The Protective Glass
Last, but certainly not least, is the protective glass layer. This isn’t your average pane. It’s tempered, and hardened through thermal or chemical processes, to withstand substantial impact, including the wrath of a hailstorm.
This glass guardian ensures your solar cells can do their job come rain or shine.
Solar Panels vs. Hail
Now that we know what solar panels are made of, let’s address the million-dollar question. Can they really stand up to a hailstorm?
Standards for Solar Panel Durability
Yes, they can. Solar panels undergo stringent testing before they hit the market. One of these tests called the “hail impact test,” involves propelling one-inch hailstones at 50 mph toward the panels.
If they can withstand that, they can stand up to most hailstorms.
Real-World Scenarios
Remember the massive Denver hailstorm in 2017? With hailstones the size of baseballs, it caused substantial damage, but the solar panels at the National Renewable Energy Laboratory nearby came out unscathed.
Ensuring Solar Panel Resilience
Solar panels are designed to be tough, but they’re not invincible. Ensuring their resilience and long-term functionality involves a bit of legwork.
Regular Maintenance
Regular maintenance is crucial. Keep your panels clean and clear of debris. Dirt, leaves, or even bird droppings can reduce the amount of sunlight your panels absorb, decreasing their efficiency.
Annual inspections by a professional can catch any potential issues before they become costly problems.
While it’s true that solar panels are designed to endure hail, additional precautions can be useful, particularly if you live in a hail-prone area. Protective covers, for instance, can shield your panels during severe storms.
Insurance
Most importantly, don’t forget about solar panel insurance. Many homeowners’ insurance policies cover solar panels.
In case your panels suffer damage from a severe hailstorm or any other unexpected event, insurance can save you the cost of repair or replacement. Make sure to check your policy or speak to your insurance provider to ensure you’re covered.
The solar panel’s battle against hail is an endurance race, not a sprint. With proper care and precautions, your panels can weather the storm and continue to provide clean, renewable energy for years to come.
What Size Hail Can Solar Panels Withstand?
Extremely severe hailstorms with larger hailstones and higher speeds can potentially cause damage.
Solar panels are engineered to withstand the impact of hailstones up to 1 inch in diameter, propelled at approximately 50 mph, which is a standard in the solar industry.
This standard was established considering typical hailstorm conditions. It is worth noting, however, that this doesn’t make solar panels impervious to hail damage.
What Happens if a Solar Panel Is Damaged by Hail?
If a solar panel is damaged by hail, its performance can be adversely affected.
Minor damage might cause a drop in energy production, while significant damage such as shattered glass or broken cells can lead to complete failure of the panel.
It is important to inspect panels after severe hailstorms and arrange for repairs or replacements as necessary to maintain optimum power production.
Are Certain Types of Solar Panels More Resistant to Hail?
All solar panels are designed to meet certain durability standards, but some may have features that make them more hail-resistant.
For instance, panels with thicker tempered glass and robust frame structures can better withstand hail impact. Furthermore, specific panel designs, such as those with fewer points of failure or those that use flexible materials, may also offer superior resilience against hail.
Always check a panel’s specific features and certifications when considering hail resistance.
Can I Protect My Solar Panels From Hail Damage?
While solar panels are engineered to be resilient against hail, you can take extra measures to protect them, particularly if you live in a hail-prone area.
One option is to use protective covers or shields during severe weather conditions. These covers are designed to absorb the impact of hail, reducing potential damage. Moreover, installing a monitoring system can alert you to any efficiency drops, indicating potential damage.
However, these precautions should be balanced against the need for panels to receive maximum sunlight, and covers should be removed when not necessary.
How Do I Check My Solar Panels for Hail Damage?
After a hailstorm, perform a visual inspection of your solar panels from a safe distance.
Look for any visible signs of damage such as cracks or shattering in the glass, dents in the panel casing, or any unusual dirt or residue that could suggest internal damage. A sudden drop in system performance can also indicate damage.
For a comprehensive assessment, consider hiring a professional. They can safely perform a detailed inspection and test system performance to ensure your panels are operating effectively.
Can Solar Panels Withstand Hail
In the battle against hail, solar panels more than hold their own.
Solar panels are built to weather the storm, literally. But like all things, they require care.
With regular maintenance and the right insurance, your investment in solar energy will be secure, come rain, snow, or hail.
