When it comes to harnessing solar energy, the promise of a clean, renewable power source is hard to resist. However, the journey to sustainable energy isn’t without challenges, especially when nature decides to wreak havoc.
From scorching heat waves to pounding hailstorms, extreme weather conditions can pose significant risks to solar panel systems. Extreme climate brings unique challenges that are not insurmountable.
In this blog, we explore the real-world impact of severe weather on solar systems and share practical solutions to keep your investment running efficiently, no matter what the forecast says. With the right blend of technology, proper installation, and regular upkeep, solar panels can be equipped to handle even the harshest conditions.
Impact of High Temperature on Solar Panel Efficiency
While solar panels rely on sunlight, excessive heat can reduce efficiency, leading to lower energy output. In areas affected by scorching heat, solar installation owners often experience a decline in energy output during peak summer months.
A National Renewable Energy Laboratory study found that solar panel efficiency can drop by up to 20% when temperatures exceed 38°C (100°F). Implementing cooling systems or fitting PV panels with high-temperature resistance and lower temperature coefficients can somewhat mitigate this issue. Then, optimising panel tilt and orientation with thermal management materials can also help minimise the impact of high temperatures.
Damage from Hailstorms and Severe Weather
Hail can cause physical damage, such as cracks or shattering of solar panel surfaces, leading to reduced energy efficiency or complete system failure. For instance, in 2017, a hailstorm in Denver, Colorado, damaged thousands of panels, illustrating the vulnerability of solar installations to such events.
Owners in these areas can mitigate risks by investing in high-impact resistance panels certified under IEC 61215 standards and installing protective coverings like tempered glass or hail guards. Regular inspections and maintenance can help identify potential vulnerabilities and ensure that solar panels are securely fastened to withstand severe weather conditions.
Performance in Snowy and Cloudy Conditions
Constant snowfall and cloudy weather often reduce solar power generation due to prolonged phases of obstructed sunlight. Studies by the European Photovoltaic Industry Association revealed a 25% to 55% decrease in Photo Voltaic output in cloudy and snowy climates, respectively.
Owners can address these issues by installing panels at a steeper tilt to encourage snow to slide off, using snow-clearing tools specifically designed for solar systems with anti-reflective coating. Opting for bifacial panels, which can capture sunlight through the reflection on snow-covered surfaces, can improve overall efficiency to some extent.
Degradation from Humidity and Heavy Rainfall
High humidity and frequent heavy rain spells can cause corrosion and oxidation of solar panel components, causing a drop in energy flow. These are commonly found in tropical and coastal regions like Kerala, where multiple rains throughout the year cause moisture to seep into the panels, leading to system failure.
Investing in panels with high IP (Ingress Protection) ratings, such as IP67 or IP68, is recommended to increase their lifespan. Proper sealing techniques and anti-corrosion coatings enhance durability and safeguard panels against water and grease build-up.
