For homeowners in Berwyn and throughout southeastern Pennsylvania, winter weather brings snow, shorter days, and a common question: do solar panels actually work in the snow? It’s a valid concern for anyone thinking about investing in solar energy, especially in a region known for its seasonal weather shifts. The good news is that solar panels are more winter-ready than many people realize—and understanding how they perform in cold, snowy climates can help you make a more confident decision about going solar.
At O’Donnell Solar Co, we specialize in designing and installing solar systems that are optimized for the year-round conditions of Pennsylvania. That means even when the snow starts falling, your panels are still working for you.
Solar Panels Thrive in Cold Weather
One of the most surprising facts about solar panels is that they actually perform more efficiently in colder temperatures. While solar power is associated with sunny climates, it’s the light—not the heat—that matters most. In fact, cold temperatures improve the conductivity of solar cells, which means your panels can generate electricity more efficiently when the weather is crisp.
So while a bright summer day may provide longer hours of sunlight, a cold, clear winter day can still deliver excellent solar output—especially when panels are angled correctly and installed professionally, as we do here at O’Donnell Solar Co.
What Happens When It Snows?
Snow on your panels will temporarily reduce energy production, just like cloud cover or shading would. But thanks to the smooth, angled surface of most solar panels, snow tends to melt and slide off quickly—especially when the sun comes out. Black photovoltaic panels naturally absorb heat, which helps accelerate the melting process even on colder days.
In Berwyn and the surrounding areas, snowstorms typically don’t lead to prolonged panel obstructions. Most systems continue producing energy shortly after snowfall ends, without any need for manual intervention.
Should You Clear Snow Off Your Panels?
In most cases, the answer is no. Solar panels are installed at angles that encourage snow to slide off naturally, especially when mounted on sloped roofs. Climbing onto your roof to remove snow is dangerous and generally not necessary. However, if heavy snowfall builds up and energy production is significantly limited, specialized tools like soft-bristled snow rakes can be used from the ground. Just be sure to avoid anything that could scratch or damage the panels.
If snow accumulation is a persistent concern, our team at O’Donnell Solar Co can walk you through panel placement options and strategies for maximizing winter output, including ground-mounted systems or steeper tilt angles.
How Much Energy Will You Generate in Winter?
While winter days are shorter and often cloudier, your solar system is designed to meet your annual energy needs, not just day-to-day usage. Production naturally dips in winter, but higher output during spring, summer, and fall balances out your overall energy generation for the year.
That’s why it’s important to work with a solar company that understands Pennsylvania’s seasonal patterns. At O’Donnell Solar Co, we take into account the entire year’s solar potential when we design your system, ensuring reliable performance across every season.
Solar Power Still Makes Sense in Pennsylvania
Even with winter’s challenges, solar remains a smart investment for homeowners across southeastern PA. Between federal tax credits, net metering programs, and long-term utility savings, solar panels continue delivering value regardless of a few snowy weeks.
Plus, with electricity costs on the rise, reducing your reliance on the grid—even during the colder months—gives you more control over your energy bills and greater peace of mind.
Local Expertise Makes the Difference
Choosing the right solar partner matters—especially in a state with four full seasons. At O’Donnell Solar Co, we’ve helped countless homeowners in Berwyn and across southeastern Pennsylvania harness solar energy with systems designed for local conditions.
Our team will assess your roof, orientation, shade, and local weather to create a custom solar solution that performs in every season. From panel placement to system monitoring, we’re here to ensure your investment in solar works—even when it’s snowing outside.
