Why Clean Solar Panels?
Once you get your solar panels installed, you will find them fairly maintenance free. Most are rated for a very long 30 year lifetime. As you can see from the above picture, solar panels can get dirty. Pollen, bird droppings, dirt, and dust can build up on solar panels. We try to clean solar panels at least two times a year. March/April when the rainy season has passed, and August/September, towards the end of summer. Pollen from our nearby evergreens really sticks to the panels. Try to clean pollen off before it bonds, otherwise a cleaning solution may be needed.
