Do Solar Panels Work in Snowy Conditions?

 

Homeowners interested in upgrading to solar in East Washington frequently ask us questions about solar panel performance in frigid winter weather conditions. They’re often surprised to find out how much solar energy can be produced during the cold weather season. How well do solar panels work in snowy conditions?

 

Talesun solar panels work well in cold, snowy conditions

• Solar panels perform better in cold weather

• Solar power systems still generate energy when partially covered with snow

• Snow’s highly reflective properties increase available sunlight

• When installed properly with a steep tilt, solar panels naturally shed snow

 

Can Solar Panels Generate Electricity When Covered in Snow?

 

Partial snow accumulations, especially powdery snow, still allow sunlight to penetrate solar panels. Choosing panels with bypass diode technology allows current to flow around snow-covered sections, minimizing loss. Though heavy, wet snow accumulations can limit production, installing solar panels with a steep mounting angle of 30-45° facilitates natural snow clearing. Highly reflective snow also increases the amount of sunlight available for absorption, even on overcast days. Installing bifacial solar panels, which collect light from both sides, ensures maximum energy production. Our Tier-1 Talesun solar panels withstand snowy East Washington weather, including these cutting-edge technology options to provide reliable performance in cloudy, snowy temperatures down to -40°F.

 

Do Cold Temperatures Impact Solar Energy Generation in East Washington?

 

Residential solar systems typically perform better in cold weather. Solar panels require sunlight, not warmth, to produce solar power. As temperatures lower, electrical conductivity improves and resistance decreases, facilitating higher voltage output and enhanced efficiency per watt of sunlight absorbed by solar panels.

How Can I Maximize Solar Power Production in the Winter?

 

Professional solar power system configuration and installation, routine maintenance, and battery backup storage are essential for maximizing winter power production and ensuring consistent availability. Our East Washington solar panel installers ensure success, installing the right number of solar panels at the ideal location and orientation for optimal solar gain. We securely mount solar panels with a steep tilt to facilitate natural snow sloughing. Our solar panel company also provides solar health checks, advising you on how to monitor performance to quickly detect factors impacting efficiency.

 

Should I Clean Snow from My Home Solar Panels?

 

Occasionally, snow will not shed after multiple days of frigid, icy conditions. It can be safely removed in this situation with the proper solar panel maintenance techniques and tools. Our solar panel maintenance team stresses the importance of working only from the ground, using an extendable pole and a non-abrasive snow rake with a rubber or foam edge to avoid damaging solar panel glass. As with auto glass, never pour warm water or chemicals on snow-covered solar panels. Leave rooftop removal and stubborn ice to the pros.
