Sticky tree and plant sap, lichen, soot and bird droppings are just a few of the things that can contribute to a build-up of dirt on your solar panels.

This creates shading on the solar panels and will prevent sunlight reaching the cells. This results in poor system perfomance, loss of efficiency and a loss of financial return for the owner and investor of solar energy. 

 

       Dirty solar panels: 

• Lose efficiency and lifespan 

• Reduce overall system performance

• See a loss of return on investment

• Affect your limited warranty

 

       Regular solar panel cleaning:

• Ensures a maximum output

• Maintains your warranty

• Saves you money

• Extends the life of your investment

"Solar panels are self cleaning and maintenance free"

 

When a solar panel is called self cleaning, it tends to mean that water droplets cannot stick to the surface. In essence, these surfaces aren’t exactly self-cleaning and maintenance free. They do reduce mineral residue that can block the sun reaching the cells, however, we have to take into account our climate.  

A single solar cell within the panel can become inefficient and this will affect the performance of the rest of the cells within the panel. As they are wired in series, if one cell is shaded, then the output of the entire panel is lower as a result.

Rain alone is not enough to ensure solar panels remain free from a build-up of dirt throughout one year, let alone a lifetime.

Manufacturers state that dirty solar panels will result in a loss of output!
