Will cleaning my solar panels make a difference and save me money on my utility bill ?
The Answer is Yes!
The efficiency of your solar panels decreases over time if they’re not kept clean. Cleaning your solar panels will remove any dirt, pollen, bird droppings and other debris that could be blocking sunlight from reaching the photo cells. Even fine dust and dirt can cause enough of a shading effect to decrease energy production. The amount of power generation lost depends on how dusty or dirty the panels are. A study by the National Renewable Energy Laboratory found that dirtiness can reduce a panel’s output by up to 30%. That loss in energy production translates into a higher electricity bill from your utility company. The build-up of dirt and grime can also cause the panel to overheat, which can shorten its lifespan.
How often do my solar panels need to be cleaned?
The frequency of cleanings can vary based on many factors.
Many homeowners are under the impression that rainfall alone will keep their solar panels clean, which isn’t true. Over time the buildup of debris will become adhered to the surface of panels requiring more than rain to clear it off. The amount and type of vegetation near your home also plays a role in how dirty solar panels become. Pollen, leaves, and other plant debris will find their way to the surface of solar panels blocking sun light. Homes near open space, dirt lots, ball fields, gravel parking lots and construction are especially susceptible to dust and dirt accumulating on solar panels. It is recommended to have your solar panels cleaned at least once a year. Adequate cleaning routines can vary widely depending on the things listed above. I have found that having your solar array cleaned biannually can show significant savings on utility costs. We offer discounts to costumers for biannual and quarterly cleanings.
Bird and Rodent Proofing
Hearing Noise on Your Roof?
Solar panels provide a comfortable and protected shelter for birds to nest and other rodents, such as mice, rats and squirrels to wreak havoc. Not only will they create a lot of unwanted noise and messes on the roof, they can also cause damage to the wiring underneath the solar panels. We offer a service that will make it impossible for these pests to make their way under your solar array. We use a coated steel mesh fencing that will withstand a lifetime of abuse from the elements and strong enough to avoid being chewed through like some pest proofing products used by others.
