Cleaning, Denver-Specific
The Denver metro has its own soiling profile. Cottonwoods drop heavy pollen and fluff in late spring and early summer, urban dust settles year-round, and pigeons leave their mark on city rooftops. Together that builds a film on panels that blocks sunlight and quietly costs output — most homeowners don't notice until they look at the numbers.
We're building our Denver routes on purpose, and we schedule metro cleanings together where we can so the trip's efficient and your timing still works.

- Roof and array check — before we start cleaning

Customer Reviews
"Where do I start? Amazing work. Great detail. No one else will service my solar panels, only this company! Great customer service. Goes the extra mile to make sure you are well taken care of."
"Cannot recommend this company enough! Nick came the same day I called and gave us a free estimate. He scheduled very quickly and was super efficient. Very communicative as well."
"These guys took care of the pigeon problem that had developed under my solar panels, cleaned my gutters, put up critter guard, and gave the panels a good cleaning. They charged me a fair price, provided excellent customer service, and were 100% transparent about the process."
FAQs About Solar Panel Cleaning in Denver
What Denver homeowners ask us most often about cleaning their array.
-
Cottonwood pollen ruined my spring production again. Can you fix it?
Yes — this is one of our most common Denver calls. Cottonwood drop in late May and June leaves a sticky film that rain doesn't move. Best timing is a post-pollen cleaning in late June or early July to recover the summer months. Park Hill, Wash Park, Highlands, and older neighborhoods with mature cottonwoods see this every year. -
My panels look fine from the ground. Is cleaning really worth it?
Depends on what "look fine" means. Cottonwood film, pine pollen, city dust, and wildfire ash often aren't visible from the driveway but cost 15-20% of production from a typical Denver system through summer. We compare your output to what your system should produce; if cleaning won't help, we'll tell you straight before booking. -
It rained — won't that handle it?
Rain handles light dust. It doesn't move pollen film, bird droppings baked on, lichen, or wildfire ash sediment. After spring storms a lot of Denver customers expect the panels to be clean and find them still streaked. That residue is what cleaning targets. -
How much does cleaning cost in Denver?
Most Denver residential cleanings: $425-$525. Larger arrays, multi-story access, or systems with heavy buildup can run higher. Estimate is always free. -
Will cleaning void my Enphase / SolarEdge warranty?
No. Routine cleaning by spec — soft-bristle, deionized water, no chemicals, no high-pressure spray — doesn't interfere with panel or microinverter manufacturer warranties. The methods that void warranties (abrasive brushes, pressure washing, cold water on hot panels) are exactly what we don't do.
