Solar Panels are great. They convert sunlight into energy so we can power our homes or heat our water. What happens when they collect leaves, bird droppings and airborne particles though?
When solar panels get dirty they produce less power. Solar panels work by allowing light into the solar cells. That means, the more light that hits the panels, the more energy you achieve. So, it makes sense that grime and debris on the panels would decrease the ability of the panels to produce energy at full capacity. Therefore, the best solution would be to have them cleaned regularly.
When it rains it would make sense that they are getting cleaned though, right?
Think about your car windshield, when it rains we use our wipers and the area that the wipers don’t touch gets a film making that area very difficult to see through. It is the same for solar panels. Rain contains airborne dust and particles that settle and attach to your windshield or in this case solar panels after the water has evaporated.
