What happens if solar panels get dirty?
When solar panels are dirty, they can lose up to 30% of their efficiency. That means that if your solar panel is covered in dirt, dust, or bird droppings, it won't be able to produce as much power as it normally would. Solar panels are an increasingly popular way to generate electricity, but what happens when they get dirty?
Do dirty solar panels affect performance?
While it's true that dirty solar panels can negatively impact performance, it's important to keep things in perspective. Most residential solar installations are connected to the grid. Any drop in production due to dirt or debris will simply be made up by drawing power from the utility company.
Are clean solar panels better than dirty solar panels?
Though 6.3% might not seem like a lot, it's a loss that can add up over time. This makes a noticeable difference between clean vs dirty solar panels in the overall efficiency of your solar power system. Therefore, the experiment really proves the importance of regularly cleaning your solar panels.
How does dirt affect solar power?
Solar panels rely on sunlight to generate electricity, and dirt can block that sunlight and reduce the amount of power the panels can produce. How much power is lost depends on how dusty or dirty the panels are. A study by the National Renewable Energy Laboratory found that dirtiness can reduce a panel's output by up to 30 percent.
