LAGUNA BAY SOLAR CLEANING is owner operated with experience in multiple industries. We offer affordable rates from as low as $5.95 per panel. When someone gets a new rooftop solar installation, one of the questions they always ask is "how often do I need to clean my solar panels"?

Rooftop solar panels get dirty mostly from wind-blown dust, leaves and pollen. Birds are usually not a problem but bat excrement, leaf debris, dust, and solar panels near major roadways can cause issues to your solar revenue.

As panels get dirtier, their output declines. A dusty film may only cause a 5 percent output decline. However, when panels get very dirty the output decline can be greater than 20 percent. On the coast we get a good amount of rain but this is not enough to remove all residue.

If your panels are tilted on 5 degrees or less, the rain may leave a puddle of soiled debris along the lower edge of the panel. When this puddle dries, sometimes a thick layer of dirt accumulates along the lower row of cells (sometimes moss and weeds may even grow in these areas). Depending on the design of the system, this small accumulation of dirt can cause a significant decrease in output.

So the answer to the question: "how often should I clean my solar panels?" really depends on five factors: your location, the tilt angle of your panels, the amount of wind-blown dust and other soiling factors, your electric rate, and the cost to clean your panels. From as little as $5.95 per panel 2-3 times a year it is affordable, safe and viable.

By having your panels professionally cleaned every 4-6 months you will ensure that your panels are working as efficiently as possible. This will ensure that you have an effective system that produces the most energy that the sun has to offer.
