Other factors include the age of your solar panels, your surrounding vegetation, and the type of panels you have. By taking into consideration these factors, you can ensure that your solar panels stay as dirt-free as possible, which will result in better performance and a more efficient use of solar energy.

– Signs That Your Solar Panels Need Cleaning

If you want to keep your solar panels running optimally for as long as possible, it’s important that you keep them clean. But how often should you clean them? That largely depends on your location and the conditions your solar panels regularly face. Here are some common signs that your solar panels need cleaning:

1. Reduced efficiency – If you aren’t generating as much electricity as you normally do, it might be time to clean your solar panels. Dirt and debris on your panels can reduce their efficiency, leading to less energy production.

2. Bird droppings – While it’s tough to avoid, bird droppings on your solar panels can be harmful. Not only can they block sunlight, but they can also corrode your panels if left for too long. Check your panels regularly for any signs of bird droppings and clean them off as soon as possible.
