Solar panels work best under clear, sunny skies. But most people don’t realize that they will keep generating energy even when the weather isn’t perfect. If you are wondering, “Are solar panels weather resistant?” the answer is yes! Weather resilience is a vital feature in solar panel system design. While there are common concerns about solar panels in extreme weather, you might be surprised at how well your panels perform in bad weather.
Solar panels can withstand rain, snow, ice, winds, and even hail if properly built and protected. They can even generate energy as long as some amount of sunlight is present.
Solar Panels and Different Weather Conditions
Let’s take a look at how solar panels can perform in different weather climates and conditions.
- Heavy Rain – Clouds can obscure the sun and reduce solar production, but rain does not actually interfere with your panels. Most solar panels are built with waterproof design features and rain offers self-cleaning benefits.
- Snow and Ice – Solar panels actually perform better under clear skies when the temperature is cooler. Snow can also reflect light back onto the panels, improving their performance. However, snow clouds and snow on the panels will reduce solar performance. Be sure to prepare your panels at the right angle for snow-shedding and consider the weight tolerance of your panels.
- High Winds – Different panels and mounting systems offer differing wind resistance ratings. If you live in a region that has seasonal high winds, be sure to choose a mounting system that offers wind resilience.
- Hail – Solar panels do need to be protected from hail. This can be accomplished with a protective layer of impact glass.
Technology and Design Features for Weather Resilience
Solar panel technology continues to evolve, increasing panel performance, protection, and ability to adapt to various weather conditions.
- Tempered glass encased solar panels offer improved durability in the face of hail and debris.
- Aluminum framing is lightweight yet offers a high degree of durability.
- Weather-sealed junction boxes ensure that your electrical components are protected in bad weather.
- Make the right choice between micro-inverters vs. string inverters based on your local weather and harsh conditions.
- Choose advanced mounting systems for optimal angle and stability.
Maintenance and Preparation for Extreme Weather
If your solar panels are going to withstand bad weather, maintenance is a must.
- Regular inspections ensure that your panels are ready for the next storm and haven’t been damaged by recent harsh weather.
- Cleaning procedures also vary depending on the climate. Consider the importance of wiping away dust in the summer versus ensuring the panels remain clear of snow in the winter.
- You can make seasonal adjustments to your panels to absorb even more electricity because the sun comes in at different angles during different times of the year.
- Be certain to invest in professional installation so your panels are skillfully mounted and built to last.
- You can also integrate weather monitoring systems to let you know when to cover your panels or when to trigger an automatic shutoff for safety.
Long-term Performance and Warranties
Panels that withstand bad weather provide greater peace of mind with protection and warranties.
Look for great manufacturer and installation warranties that could cover repairs after weather damage. You may also want to look into weather-degradation rates and performance guarantees in various climates.
Conclusion
Are solar panels weather-resistant? Many panels are built to withstand bad weather and some designs are uniquely suited to different climates. Consult with Solar Optimum to see if solar panels are right for your home.
