Question 3

How often should solar panels be cleaned and maintained?

Accepted Answer

Most solar systems should be professionally cleaned and inspected at least once or twice a year depending on dust, pollen, bird debris, smoke, and weather conditions. Regular maintenance helps maximize system efficiency and lifespan. Since we mostly service in the tri cities and eastern Washington region we recommend about two times a year due to high amount of dust.
