If you’ve installed solar panels on your home in Massachusetts, you’re likely familiar with the benefits, clean energy, long-term savings, and a smaller carbon footprint. But you may have also discovered something else along the way: solar panels get dirty, sometimes faster than you expect.
Why Clean Solar Panels Regularly?
Dirty solar panels don’t perform as well. When dust, leaves, or droppings cover the surface, less sunlight gets through and that means less energy production. In fact, according to the National Renewable Energy Laboratory, panel efficiency can drop by up to 25% in areas with regular buildup.
Most homeowners don’t want to be on the roof scrubbing panels. That’s where professional solar cleaning comes in, and in Massachusetts, the cost typically ranges between $150 and $300 per visit, depending on roof pitch, accessibility, and panel quantity.
What’s Making Panels Dirty in Massachusetts?
- Bird droppings from pigeons or starlings
- Squirrels and nesting debris under and around the panels
- General air pollution in denser cities like Boston or Worcester
