If you have solar panels this is worth understanding before your next energy bill arrives.
Most solar owners focus on panel maintenance and rightfully so.
What most people never connect is the relationship between gutter condition and solar panel output. Here is how it works.
Blocked gutters overflow during rain. When water spills over the edge of a gutter it does not just fall straight down. It splashes.
Debris, grime and dirty water land on whatever is below the overflow point, which on many Australian homes includes the lower edge of the solar panel array.
Over repeated rain events this builds up a layer of grime on the panel surface that reduces the amount of sunlight reaching the cells underneath.
Studies on solar panel soiling in Australian conditions consistently show output losses of 15 to 25 percent on panels that have not been maintained.
For a system that was supposed to be cutting your energy bill that is a meaningful and ongoing loss.
The most efficient way to address both is a combined gutter and solar panel clean in a single visit.
Gutters cleared, panels cleaned, system performing the way it was designed to.
