Surface pollution of rooftop solar panels

A typical rooftop solar system pays for itself in 7-10 years, leaving solar owners with 15-18 years of free electricity production while the panels are still under warranty. And remember, solar panels don''t disappear when they reach the end of their warranty, their production capacity just slowly degrades over time.
