Solar energy is a plentiful and clean source of energy that can outperform many conventional energy sources at a lower cost. However, its reliance on the sun has limitations, such as weather conditions. Many potential solar panel buyers are concerned about how snow and clouds affect solar panels.
Discover how different weather conditions impact your solar panel performance
Solar panels work by converting sunlight into electricity, so they are less productive on cloudy days than on sunny days. The amount of electricity produced by solar panels on cloudy days also depends on the thickness of the cloud cover.
Thin clouds may not have much impact on performance, but on partly overcast days, even the best solar panels can produce 10-25% less electricity.
Rainy days are not as bad as they may seem, as the rain can wash away dust and dirt that can reduce the efficiency of the panels.
One common misconception about the effect of weather on solar panels is that high temperatures can increase their efficiency. However, the opposite is true: solar panels are more productive when temperatures are lower. This is because high temperatures cause the voltage of the PV cells to drop, which reduces their power output. Therefore, a cool sunny day is the best condition for solar panels to operate optimally.
Modern solar panels are designed to withstand winds up to 90 mph, but poorly designed panels may not perform as well. However, even when a solar system fails due to wind, it is rarely the panels that are at fault. In most cases, the problem is with the racking system or the roof where the panels are mounted. Dust and flying debris can also affect solar panels in windy conditions, but most panels are resilient enough to withstand these conditions.
Lightning can damage solar panels and inverters, depending on how it strikes. A direct lightning strike can even melt the panels, but indirect strikes are more common and can cause voltage surges that damage various components of the system. If you live in an area prone to lightning strikes, you may want to consider getting insurance for your solar panels.
While a thick layer of snow can reduce the energy production of solar panels, a light dusting of snow is not a big deal, as some sunlight can still pass through. Additionally, rooftop solar panels are typically installed in a way that allows snow to slide off naturally. Surprisingly, the snow around the home can actually increase solar energy generation, as the reflected radiation from the snow acts like a mirror, increasing the intensity of the radiation reaching the solar panels in winter.
As technology advances, solar panels are becoming more durable and productive, even in harsh weather conditions. Customers should understand the conditions in their region before choosing the best solar panels for their needs.
Solar panels are a great investment for homeowners and businesses who want to reduce their energy costs and environmental impact. However, it is important to choose the right solar panels for your needs and to understand how weather conditions can affect their performance. By following the tips in this blog, you can ensure that your solar panels will provide you with clean and renewable energy for many years to come.
