Solar energy is one of the best sources of clean and green power. More and more people are choosing rooftop solar panels for their homes. But a common question still comes up in our minds regarding the performance of residential rooftop panels during change in climatic conditions.
The simple answer is yes. The weather does impact your solar rooftop device. But the good news is, modern solar technology is made to handle different climate conditions. In this blog, we will understand HOW?
1. Various Weather Conditions That Affect Solar Rooftop Systems
Your solar rooftop system is designed to work under the open sky. This means it faces all types of climate. Here are a few conditions that can affect its performance:
Cloudy Days
Clouds block sunlight. Less sunlight means less power generation. On cloudy days, your system can also produce 10% to 25% less energy. However, solar panels can still generate some power even if it is cloudy.
Rainy Season
Rain doesn’t stop solar panels from working. Infact, light rain helps clean the panels. This improves their overall performance later. But dark clouds at some stage in the rainy season reduce energy output.
Extreme Heat
Surprisingly, too much heat can lower solar performance. Rooftop solar panels work best in daylight, not heat. High temperatures can reduce the panel’s power output by a small percentage.
Cold Temperatures
Many people think solar panels won't work well in cold weather. But that’s not true. Residential rooftop solar panels perform better in cooler temperatures. Just like any other electronic device, solar panels work better when they don’t overheat.
On sunny winter days, your solar rooftop can produce good amounts of electricity, sometimes even more than in the summer.
Storms and Strong Winds
Good quality residential rooftop solar panels are tested for harsh conditions. Panels can handle wind speeds of up to 200 km/h and are generally tested for storm impact. Proper set up guarantees they stay secure.
2. Does Solar Module Technology Work in the Rainy Season?
Yes, solar panels do work at some point during the rainy season.
Cloudy skies
The panels may not work at full capacity, but they still generate electricity in dull sunlight.
Rain blessings
Rain washes away dust and dirt. This keeps the panels clean and improves overall performance on sunny days.
Smart system
Some advanced solar rooftop systems come with battery backups. These store energy for use during cloudy days or at night.
Also, with net metering, you can take power from the grid when the sun isn’t shining, and supply back extra power while your panels produce more.
Tips to Ensure Your Rooftop Solar Panels Do Not Get Affected Due to Extreme Weather Conditions
3. Tips to Ensure Your Rooftop Solar Panels Do Not Get Affected Due to Extreme Weather Conditions
Here are some simple but useful tips to protect your residential rooftop solar panels in extreme weather:
Choose a trusted installer
Pick a certified solar company that uses Top-quality panels and ensure proper installation.
Regular maintenance
Clean your panels regularly, especially after storms or dusty weather. Check for leaves, bird droppings, or any damage.
Use strong mounting systems
Make sure the mounting structure is strong and rust-proof. It should be able to handle heavy wind or rain.
Check wiring and connections
Have a technician check the wires and inverters from time to time. This prevents energy loss or any safety risks.
Conclusion
Yes, weather can affect the performance of residential rooftop solar panels, but not in a major way. Today’s solar rooftop structures are constructed to survive in all types of climate, be it rain, heat, cold, or wind. With everyday care and the best setup, your solar panels can work efficiently all year round.
