-is used to describe the accumulation of snow, dirt, dust, leaves, pollen and bird droppings on PV panels.
The performance of a PV module decreases by surface soiling, and the PV power loss increases with an increase in the quantity of soil on the PV module.
DIRTY SOLAR PANELS
Soaps and other Cleaners
Soaps can leave a film or residue that not only shades panels like the dirt that was just washed off, but it can also encourage dirt to stick and build up faster, using deionized water cleaning requires less water, fewer passes and no harsh chemicals or detergents.
Weather
When rain happens soil accumulates at the bottom edge of the solar panel, obstructing the lower PV cell row and hindering the production efficiency.
Hot Spots
Soiling also causes Hot Spots, which means the current can’t flow properly, it causes increase resistance, the shading is lowering the amount of irradiance that hits the panel and the hot spots brings down the voltage due to cell temperature. The accumulation of nest materials and bird droppings create Hot Spots leading to subsequent failures of cells within the panels.
We use an Unger Stage One Water purification system. Which ensures a clean and residue free finish.
A thorough inspection of your solar panel equipment helps prevent panel malfunction and keeps your solar energy system performing highly efficiently.
Making sure animals such as squirrels and birds are not causing damage. Sometimes they like to move-in unannounced. We want to make sure your system is free of damage.
