Solar panels have become a popular means of long-term electricity bill reduction, especially since subsidies were approved for their installation. However, one of the biggest uncertainties is how efficient they actually are during winter months when electricity bills tend to be highest.

Factors Affecting Solar Panel Efficiency in Winter
- Sunlight vs. Temperature: Solar panels generate electricity from sunlight, not heat. Thus, during winter, the decrease in energy production is mainly due to fewer sunny days rather than colder temperatures.
- Optimal Operating Temperature: Like most devices, solar panels have an ideal operating temperature for maximum efficiency, which is not necessarily during the hottest summer temperatures. High temperatures may decrease efficiency but won’t damage the panels.
- Adjusting Panel Position: To enhance efficiency during winter, adjusting the angle of solar panels is crucial. Since the sun is lower on the horizon in winter, panels should be tilted more vertically to capture sunlight effectively.
Winter Maintenance Tips for Solar Panels
- Snow Impact: Snow accumulation can significantly reduce panel efficiency by blocking sunlight. A more vertical panel angle not only improves sunlight collection but also facilitates snow sliding off.
- Snow Removal: Safely removing snow from panels is important to prevent damage and ensure optimal performance. Use a soft-bristled brush with a long handle to gently remove snow, avoiding items that could scratch the surface.
- Risk of Damage: Accumulated snow can pose a risk of structural damage to panels and their mounts, especially on rooftops. Regular inspection and proactive snow removal can prevent potential issues.
Conclusion
While solar panels may produce less electricity during winter due to fewer sunny days, optimizing their position and performing routine maintenance can enhance efficiency and prolong their lifespan, ensuring sustainable energy production year-round.
