No! Rain does not clean your solar panels effectively or efficiently. Did you know that raindrops collect pollutants on their way down to Earth? It is true. Rainfall plays a valuable role in scavenging natural as well as artificial particles from the dirty atmosphere. This includes but is not limited to salt, chemicals, soot, acids, etc. Just imagine all the stuff in the air during fire season collected and dumped on your solar panels.
Also, the rain is not strong or consistent enough to effectively clean your solar panels. If you have ever seen a black car after a rain storm you know the debris and marks left do not indicate a clean surface. The same goes for your solar panels. Except when a panel gets dirty it not only looks bad but it is also less efficient.
