How Cold Weather Actually Boosts Solar Performance in Cambridge

SBI Editorial DeskUpdated Q1 · 20263 sections

Cambridge homeowners experience the biting cold of New England winters, which invariably leads to high electricity and heating costs. A common myth is that solar panels go dormant in the winter. In reality, the cold climate makes Cambridge an incredible location for highly efficient solar energy generation.

01

The Science of Cold Weather Solar in MA

Solar panels convert photons (light) into electrons, not heat. Extreme summer heat can actually cause resistance in solar cells. Conversely, the frigid winter temperatures in Cambridge keep the internal components of the panels cool, allowing electricity to flow with minimal resistance. A bright 20-degree day is often the most productive day of the year for a Cambridge solar array.

02

Shedding Ice and Snow

While snow coverage does block sunlight, the dark, smooth glass of Tier-1 solar panels absorbs the sun's rays and generates slight ambient heat. This causes the bottom layer of snow to melt, allowing the entire sheet to slide off the array much faster than it does on surrounding roofing materials.

03

Maximum Savings All Year

By pairing high-efficiency winter production with Massachusetts' MA SMART program, Cambridge homeowners can secure reliable power and state payouts regardless of the temperature outside.
