Storm-Proofing Solar Installations

It’s worth taking a moment to set the stage and consider weather and the challenges various events pose to solar panels.

Hurricanes

• * High Winds:Hurricanes can bring winds exceeding 150 mph, which can dislodge solar panels, break mounts, or even tear panels off roofs.
• * Flying Debris: Objects picked up by strong winds can collide with panels, causing cracks or shattering the glass.

Hailstorms

• * Impact Damage: Large hailstones can hit the panels with significant force, causing dents, cracks, or shattering the surface.

High Winds

• * Structural Stress: Continuous high winds can strain the mounting systems, leading to loosening or bending of the supporting structures.
• * Fallen Limbs and Debris: Trees and other objects can fall onto panels, resulting in breakage or scratches.

Severe Thunderstorms

• * Lightning Strikes: While direct strikes are rare, nearby lightning can induce surges that damage solar inverters and other electrical components.
• * Heavy Rain: Prolonged exposure to heavy rain can test the water resistance of the panels and mounting system, potentially leading to water ingress and electrical issues.

Extreme Temperatures

• * Thermal Stress: Extreme heat or cold can cause thermal expansion and contraction, which might lead to microcracks in the solar panels over time. Prolonged exposure to high temperatures can also reduce the efficiency and lifespan of the panels.
• * Weather-Related Efficiency Loss: Extremely high temperatures can decrease the efficiency of solar panels, as most are built to operate best within a specific temperature range. Conversely, extremely low temperatures can affect the integrity of the mounting hardware and electrical connections.

Are There "Storm-Proof" Solar Panels?

The list of potential damage from weather is a lot. And, as smart and advanced as we are, no one has yet figured out how to control the weather, which means any solar installation is, on some level, vulnerable. Hence, it makes sense that companies are offering “stormproof” solar panels. The term "stormproof" is often used in marketing to describe panels that are designed to withstand severe weather conditions. However, it’s important to understand what this term actually means and whether panels can truly be stormproof.



What Does "Storm-Proof" Really Mean?

Is stormproof worth the extra solar panel cost? The definition varies, but stormproof generally means the following:

• * Enhanced Durability: Solar panels marketed as "stormproof" typically boast enhanced durability features. These panels are often built with thicker glass, robust frames, and reinforced backing materials to resist impacts from hail and flying debris.
• * High Wind Tolerance: Manufacturers may design these panels to endure high wind speeds, sometimes up to 150 mph or more, which is crucial for regions prone to hurricanes. The mounting systems used for these panels are also designed to provide extra support against strong winds.
• * Water Resistance: Advanced sealing techniques are used to make these panels more resistant to water ingress during heavy rains and flooding. This helps protect the internal components from moisture damage.

Companies advertising "stormproof" solar panels usually emphasize impact resistance, wind resistance, and long-term reliability.

But wait - Don’t All Panels Have Those Protections?

All solar panels are built to withstand weather; they’re mounted on rooftops, after all. That said, while solar panels are designed to be robust and durable, the resilience of solar panels can and does vary.

• * Quality Variations: Not all solar panels are created equal. Panels labeled as "stormproof" are generally of higher quality and come with enhanced features compared to standard panels. However, even the best panels can sustain damage under extreme conditions. Talk to the experts at the PowerStore to determine what features you need to maximize the durability of your investment.
• * Installation Matters: The resilience of a solar panel system depends not only on the panels themselves but also on the quality of the installation and the mounting and racking systems. A poorly installed system is more likely to fail during a storm, regardless of the panel quality. The team at PowerStore guarantees your installation will be done right.
• * Roof Strength: Solar installations are only as strong as the roofs they are mounted on. If the roof is weak or damaged, it won’t provide a stable base for the panels, increasing the risk of damage during a storm. In other words, if your roof can’t survive a Cat 3 hurricane, it won’t matter whether or not your solar panels were stormproof. A thorough roof inspection prior to installation will set you on the right course.

Evaluating Storm-Proof Claims

When evaluating "stormproof" claims, consider the following:

• 1. Certifications and Testing: * Look for panels that have been tested and certified by independent bodies for impact and wind resistance. Certifications like IEC 61215 (for performance) and IEC 61730 (for safety) are indicators of a panel’s reliability.
• 2. Manufacturer Reputation: * Choose panels from reputable manufacturers known for their quality and durability. Research customer reviews and industry ratings to gauge the real-world performance of the panels.
• 3. Installation Quality: * Confirm the installation is carried out by certified professionals who follow best practices. The installation process should include securing the panels with robust mounting systems and ensuring the roof’s integrity.

While no solar panel can be completely stormproof, panels designed for enhanced durability can significantly reduce the risk of damage during severe weather. By choosing high-quality panels, working with certified professionals like PowerStore, and ensuring regular maintenance, you can maximize the durability and performance of your solar system, even in the face of severe storms. Investing in resilient solar technology and proper installation practices will help protect your investment and ensure continued energy production, no matter the weather.

Preventative Measures to Protect Solar Panels

Regardless of the panels you choose, you can take the following steps to protect your solar panels from weather damage:

• 1. Quality Installation: * Have your solar panels installed by certified professionals who follow best practices and use high-quality materials. A robust installation can better withstand high winds and impacts
• 2. Protective Barriers: * Install protective barriers like mesh guards to help shield panels from flying debris and large hailstones. These barriers can be customized to fit the specific layout of your solar array.
• 3. Regular Maintenance Checks: * Schedule regular maintenance checks to ensure all bolts and mounts are secure, and the panels are clean and free from debris. A well-maintained system is less likely to suffer severe damage during a storm.
• 4. Tree Trimming: * Keep nearby trees trimmed to prevent branches from falling onto panels during storms. This not only protects the panels but also helps maintain optimal sunlight exposure.
• 5. Surge Protection: * Install surge protectors to guard against electrical damage from lightning strikes. These devices can divert excess voltage away from your solar system, protecting sensitive components. You can also turn the system off if you know a storm is coming.
• 6. Temporary Covers: * For areas prone to frequent severe weather, consider investing in temporary covers that can be deployed quickly before a storm. These covers provide an additional layer of protection against impact damage.

Post-Storm Inspection and Repair

After a storm, inspect your solar panels for any signs of damage.

• * Visual Inspection: Check for obvious signs of damage, such as cracks, shattered glass, or panels that have been dislodged. Also, look for any debris that may have accumulated on the panels. Tip: take photos before the storm to use for comparison.
• * Electrical Check: Ensure the system is still generating power as expected. A significant drop in output could indicate underlying damage to the panels or electrical components.
• * Structural Inspection: Examine the mounting system and supports to ensure they are still securely in place. Look for any signs of bending, loosening, or corrosion.
• * Professional Assessment: Engage a certified professional to conduct a detailed assessment. Companies like PowerStore specialize in post-storm inspections and can identify and repair damage that might not be visible to the untrained eye.
