Solar panels create energy from sunlight—not the sun’s heat. Solar panels actually produce electricity more efficiently in cooler conditions. Even in the most frigid weather, solar panels turn sunlight into electricity.
How does this work? Colder temperatures enhance energy production efficiency,1 increasing the amount of electricity produced. Electrons are at rest in cooler temperatures. When the electrons in solar panels are activated by increasing sunlight, a difference in voltage is attained —creating an electric current.
Warmer summer temperatures raise the overall energy levels of electrons in solar panels. This increased energy level decreases the energy differential that can be gained, producing less energy. A higher energy state interferes with solar panel electricity production since some energy transfers into heat instead of electricity.
Rated for Peak Temperature
Solar manufacturers rate their solar panels for peak temperature. This temperature is the point at which solar panels operate most efficiently. In the winter, it’s less likely for solar panels to reach their peak temperature. So electron reactions occur at a greater rate to more efficiently generate electricity.
Your home doesn’t need to be in Arizona, California or Florida to make reliable solar power. And solar is the clear energy solution when serious cold snaps shut down the grid.
Solar panels produce more voltage at low temperatures.1 Today, solar panels are found generating electricity on the snow-covered Rocky Mountains, and in remote regions of Alaska and Antarctica. Also, wind chill lowers ambient temperatures, which carries away heat and enables panels to perform better.
Solar Is Resilient in Cold Extremes
A solar rooftop installation is resilient in the cold and winter extremes. But don’t necessarily anticipate producing more electricity during winter versus summer months. Winter days are shorter with fewer hours of sunlight.
Sunrun solar panels with a Brightbox home battery supply dependable electricity to households in cold climates and throughout winter weather grid outages. And the sun rises every day, no matter how cold it is, to reach your solar panels and generate significant energy.
