SOLAR PANEL CLEANING

 

Dirty Solar Panels Will Decrease In Efficiency

Efficiency of solar panels is currently averaging around 15%. That is, 15% of the captured sunlight is converted into electricity which is why they are built in large arrays to generate enough power for real world household consumption. Better technology will help crank up that number above 25% but regardless of the efficiency, solar panels still need proper cleaning care and maintenance in order to operate at their rated efficiency.

Dirty solar panels can decrease the energy output by as much as 25% or one-quarter after a few months of dirt and other mentioned buildup. The rate of buildup really depends on your area but the important point to understand is that your solar panels need proper cleaning care and maintenance to perform at their rated efficiency.

More About Efficiency

Let's break down the efficiency numbers so there's less confusion. With todays solar panels efficiency of 15%, a 4 kW (kilowatt or one thousand watts) solar panel system in the bay area generates an average of 8000 kW hours in a year.

Improper care can decrease that output of power by 25% so instead of generating an average of 8000 kW hours in a year, it will generate 6000 kW hours or 2000 fewer kW hours a year!

Another way to look at this is in terms of months. If you are losing 25% of energy output per year, that equates to 3 lost months of energy output! You could have enjoyed 3 more months of zero or low electricity cost. Now, shouldn't you start taking cleaning care and maintenance more seriously?
