If you’re considering solar panels for your home or business in East Tennessee, you might wonder how our local climate impacts their performance. With sunny summers, occasional rainy spells, and even a dusting of snow in winter, the region’s diverse weather patterns bring questions about how solar panels perform in different conditions. Let’s explore weather in East Tennessee affects solar panels and how to optimize their efficiency year-round.
Sunny Days: Perfect for Solar Power
East Tennessee enjoys abundant sunshine, especially in the spring and summer months. Solar panels thrive in these conditions, converting sunlight into electricity to power your home or business. On average, the region experiences more than 200 sunny days per year, providing plenty of opportunities for solar panels to generate energy.
Why It’s Ideal:
Even if a few clouds roll in during the day, the high number of sunny days ensures consistent energy production. Over time, this makes East Tennessee an excellent location for solar energy systems.
Rainy Days: A Natural Cleaning Solution
While East Tennessee gets its fair share of rain—especially in spring and late fall—rainy days don’t halt solar energy production. Solar panels are designed to capture diffuse sunlight, meaning they can still generate electricity even when it’s overcast.
How Rain Helps:
Rain also provides a natural cleaning service for your panels, washing away dirt, pollen, and other debris that can accumulate. This keeps your system running efficiently without the need for frequent manual cleaning.
Snow and Ice: No Cause for Concern
Winters in East Tennessee are typically mild, with occasional snow and freezing rain. While snow may temporarily cover your panels and block sunlight, it usually melts quickly due to our warmer winter temperatures. Additionally, solar panels are installed at an angle, helping snow slide off faster than it does on a flat surface.
Tips for Snowy Days:
- If you experience a rare heavy snowfall, avoid using sharp tools to remove snow, as they can damage the panels. Instead, a soft snow rake designed for solar systems can help.
- Snow-covered panels aren’t a major concern because the production loss is temporary and doesn’t significantly impact your overall annual energy output.
Hot Summers: What You Need to Know
East Tennessee summers can be hot and humid, and while solar panels rely on sunlight, excessive heat can slightly reduce their efficiency. Solar panels work best in moderate temperatures, and extreme heat can increase resistance in the system, leading to lower output.
How to Optimize in Summer:
- Ensure proper installation with enough airflow under the panels to keep them cool.
- Choose high-quality panels with a low temperature coefficient, which minimizes efficiency loss on hot days.
Despite the heat, the abundance of sunlight during summer ensures plenty of energy production, making up for any minor losses caused by high temperatures.
Windy Conditions: Built to Withstand
East Tennessee occasionally experiences strong winds, especially during thunderstorms or remnants of hurricanes moving inland. Fortunately, modern solar panels are built to endure high wind speeds, and professional installers like Rocky Top Solar ensure your system is mounted securely.
Peace of Mind:
Our team designs systems to meet local wind load requirements, so you can rest easy knowing your solar panels are safe even during strong gusts.
Overcast Days: Energy Production Continues
East Tennessee isn’t always sunny—cloudy days are part of life here. The good news is that solar panels don’t need direct sunlight to generate electricity. They capture scattered light, known as diffuse sunlight, even on overcast days.
What to Expect:
On cloudy days, your system may produce 10-25% of its usual output, but the consistency of East Tennessee’s sunny weather ensures these occasional dips won’t drastically affect your system’s overall performance.
Seasonal Variations in Energy Production
In East Tennessee, energy production from solar panels naturally varies with the seasons. During summer, the longer days and direct sunlight lead to peak energy output. In winter, shorter days and a lower sun angle result in less production.
How It Balances Out:
Well-designed solar systems account for these seasonal changes. The extra energy generated in the summer can often offset the lower production during winter, especially for grid-tied systems that allow you to bank excess energy for later use.
Preparing for Severe Weather
East Tennessee’s weather can be unpredictable, with occasional thunderstorms, hail, and even tornado threats. Solar panels are rigorously tested to withstand severe conditions, including hailstones up to an inch in diameter. While no system is entirely immune to extreme weather, most panels in the region hold up well under these conditions.
Optimizing Solar Panels for Weather in East Tennessee
To make the most of your solar system in East Tennessee’s varied weather, keep these tips in mind, consider battery storage. A battery system can store excess energy generated during sunny days, providing backup power during storms or grid outages.
Conclusion: Solar Power Works Rain or Shine
East Tennessee’s climate is well-suited for solar energy. From abundant sunshine to mild winters and even the occasional rainy day, the region offers ideal conditions for harnessing the sun’s power. With the right system and professional installation, you can enjoy consistent energy production and significant savings year-round.
