It’s no secret that solar panels work best in the spring and the summer, but do solar panels work just as well in winter?
With longer days and more sunlight, it’s a great time to think about how you can spend time this summer to prepare your solar system for the colder months.
In this blog, we’ll explain why and how solar panels work in winter, the factors that influence their performance, and how to make sure your system stays effective as the seasons transition from colder to warmer months.
How Solar Panels Work in Winter
Solar panels convert sunlight (UV light) into electricity using photovoltaic (PV) cells. While winter days are shorter and the sun is less intense, solar panels still produce energy efficiently.
Interestingly, solar panels can work better in cooler temperatures, allowing the cells to operate more efficiently. In lower-quality systems, hot weather can actually reduce output, hot weather can reduce their output. This is why we specialise in premium systems, working with brands like SOLARWATT, and Tesla Energy to ensure our customers get the best output all year round.
Snow and Its Impact on Solar Panels
Snow is a common concern for solar panel owners in winter. Will snow block sunlight and stop power production? Not exactly. While snow can temporarily reduce energy generation, it’s usually a short-term issue.
Solar panels are designed with smooth, slanted surfaces, which makes it easier for snow to slide off. Once the snow melts, your panels will be up and running again.
Here’s something interesting: Fresh snow can help increase energy production. How? Snow reflects sunlight (UV light) onto your panels, boosting energy generation on sunny days.
So, while snow may seem like an obstacle, it can also give your system a little extra boost when conditions are right.
Do Solar Panels Work on Cloudy Days?
In winter, overcast days are common. So, how much power can you expect from your panels on cloudy days? A lot more than you think. Solar panels still work well under cloudy skies because they can capture diffused light.
Although they produce less energy compared to sunny days, they still provide a steady supply of electricity for your home. Solar panels can generate up to 25-40% of their usual output on overcast days. Your system can produce even more energy than this, if you also invest in home battery storage.
How to Maximise Solar Panel Efficiency in Winter
To keep your solar panels performing at their best during winter, follow these steps:
- Keep Them Clean: Snow, ice, and dirt can block sunlight. Make sure to clear off snow or debris to maximise performance. If necessary, hire a professional to clean them.
- Monitor Performance: Use a solar monitoring system to track energy production. This way, if performance drops unexpectedly, you can address the issue quickly.
- Install Battery Storage: Shorter days and longer nights can limit energy production. Battery storage systems, like the Tesla Powerwall, allow you to store extra energy generated during sunnier months, so you can use it when the sun isn’t shining.
Can Solar Panels Save You Money in Winter?
Yes, they can! Even on shorter, cloudier days, solar panels help reduce your energy bills by lowering your reliance on the grid.
And if you have battery storage, you can store excess energy for use later, which means you’re not relying on expensive grid power during the evening or on overcast days.
Conclusion
So, do solar panels work in winter? The answer is a resounding yes. While the sun may be less intense and the days shorter, solar panels continue to deliver reliable energy. Cold temperatures can boost their efficiency, and even snow can increase energy production.
At Stratford Energy, we use high-performance panels from Sunpower, known for their durability and efficiency. These panels are built to handle all weather conditions, ensuring your energy production remains strong throughout the year.
