Will Solar Panels Work During a Chicago Winter?

SBI Editorial DeskUpdated Q1 · 20263 sections

Chicago winters are infamous. Between lake-effect snow dumps, sub-zero temperatures, and icy winds, the elements push homes to their limits. A common hesitation for Chicago homeowners considering solar is whether the panels will actually work when the weather turns brutal.

01

The Cold Weather Advantage

It is a massive misconception that solar panels need heat to generate electricity. They only need light. In fact, solar panels are electronic devices, meaning they actually operate more efficiently in cold weather. The bright, crisp winter days in Chicago create the perfect environment for panels to operate at peak voltage, generating highly efficient power.

02

Handling Heavy Chicago Snow Loads

What about the snow? SunBeam Innovations exclusively installs Tier-1 hardware engineered for extreme Northern climates. Our panels are tested to withstand massive snow loads (up to 5400 Pa), meaning they will not crack under the weight of heavy Chicago snowfall. Furthermore, because the panels are installed at an angle and generate ambient heat, snow melts and slides off the dark glass much faster than it does off traditional roofing shingles.

03

Surviving Winter Grid Outages

When ice storms take down ComEd power lines, a standard solar system shuts down. By pairing your heavy-duty solar array with a battery backup system, your Chicago home can maintain its heat and essential power, completely independent from the failing grid.
