With the temperature decreasing and snow coming down, it seems sensical to ask this question. Short answer: Yes.
Solar systems are still productive, cost-effective, and a clean, sustainable energy source even in our cold and snowy months.
Based on the price of electricity in Wisconsin, with an average of 14¢ per Kwh and the average amount of sun exposure, solar power is 3% more cost-effective in Wisconsin than in the rest of the nation.
For example, Miami, FL receives an average of 5.62 sun hours per day, whereas Madison, WI receives an average of 4.29 sun hours per day. (1 sun hour equals 1 KW of solar energy per 1 sq. meter).
Solar panels rely on light and not heat to produce effectively.
That said, they could potentially be most effective in a cold and sunny climate. Ecomark Solar, a Colorado installer, also highlights the Albedo Effect in their article, “How Panels Perform During Winter.”
Essentially this depicts how the whiteness of the snow could allow for solar panels to produce more electricity by reflecting the light back much like a mirror and how skiers experience sunburn on bright yet snow-covered days (Ecomark Solar).
Endries Solar and Electric intentionally and carefully designs your system at the most beneficial positioning in relation to the sun, as well as the most scientifically proven tilt for maximum solar absorption, to ensure that you receive the greatest output possible.
When these calculations are accurately portrayed in your installation, not only do you experience a greater system output, but the calculated tilt of your panels also allows as much snow as possible to slide off as quickly as possible when heated up by the sunlight.
With Wisconsin’s tax exemption on renewables, Focus on Energy Rebate, as well as the Federal Tax Incentive and financing options, the snowy months will pose no threat to your system’s ability to work to fidelity, your positive impact on the environment, and also your return on investment.
