How Weather in the Midwest Can Affect Solar Panel Efficiency

Solar panels are an excellent investment for homeowners and businesses looking to reduce energy costs. However, the efficiency of solar energy systems can vary based on weather conditions, especially in the Midwest. States like Missouri, Kansas, Arkansas, and Illinois experience a wide range of weather throughout the year, which can impact solar energy production.

When Are Solar Panels Most Efficient?

Solar panels perform best when they receive direct sunlight without any obstructions. Clear, sunny days with moderate temperatures are ideal for maximum energy production. Interestingly, solar panels can actually be more efficient in cooler temperatures because excessive heat can reduce their output. On a sunny 77-degree day, solar panels operate at peak efficiency.

How Does the Weather Affect Solar Panel Efficiency?

The Midwest experiences a wide range of weather conditions that can influence solar panel performance.

Cloudy Days: Solar panels still generate electricity on cloudy days, but output can drop by 10% to 25%. Advances in solar technology have improved efficiency during low-light conditions, but it’s still a good idea to plan for reduced production.

Rain: Rain doesn’t harm solar panels; in fact, it can clean off dust and debris, enhancing efficiency once the skies clear. However, during heavy rainfall, output may decrease temporarily.

Snow: Snow coverage on solar panels can significantly reduce or completely block energy production. Fortunately, panels are typically installed at an angle, allowing snow to slide off. Light snow may actually boost efficiency by reflecting sunlight, while heavy snow can temporarily halt production. Using a soft-bristle broom to clear panels after a snowfall can help maintain energy generation.

Wind: Wind itself doesn’t affect solar efficiency, but strong winds can blow dust and debris onto panels, reducing their output. Regular maintenance helps minimize the impact of windblown particles.

Temperature Fluctuations: Solar panels perform optimally in cooler weather. While summer sunshine is abundant, extreme heat can decrease efficiency. High temperatures cause electrical resistance in the photovoltaic cells, slightly lowering output.

Hail: Most solar panels are built to withstand hail up to 1 inch in diameter, but severe hailstorms can cause damage. Homeowners in the Midwest should consider choosing panels with high durability ratings.

Seasonal Variations: Midwest winters mean shorter days and reduced sunlight, leading to lower solar production. Investing in a solar battery can help store excess energy produced during sunny months for use in the winter.

How To Maximize Solar Energy Generation in the Winter

The cold, snowy winters of Missouri, Kansas, Arkansas, and Illinois can pose challenges for solar energy production. Fortunately, there are several strategies to keep your system running efficiently:

• Clear Snow Promptly: Snow buildup blocks sunlight. Use a non-abrasive tool to gently remove snow from panels.
• Monitor Your System: Keep an eye on your solar monitoring app to track energy production. Sudden drops might indicate snow coverage or maintenance needs.
• Angle Your Panels Correctly: Installing panels at a steeper angle can help snow slide off more easily.
• Consider a Solar Battery: During winter, days are shorter and cloud cover is more frequent. A battery system stores surplus energy from sunny days for use during low production periods.
• Routine Maintenance: Check your panels periodically for ice buildup or dirt that could reduce efficiency.

By taking these precautions, homeowners and businesses can keep solar energy flowing even when temperatures drop.
