Your System Deserves a Second Look

A close-up physical inspection of every panel — checking for soiling level, visible buildup, bird droppings, discoloration, micro-cracks, or any signs of physical damage that could be affecting output. Things you simply can't see from the ground.

Yurii's team checks for any new tree growth, overgrown branches, or nearby obstructions that may be casting shade on your array. If trimming would meaningfully improve your production, they'll tell you — and can coordinate the work.

A general assessment of the surface area around your array, including a check for any loose wiring, exposed conduit, or connection points that may have shifted over time. Small issues caught here can prevent bigger problems down the road.

If you have access to your monitoring portal, Yurii can pull up your data on-site and review it alongside the physical assessment — looking for patterns or dips that the numbers alone don't explain.

Animals nesting under panels is more common than most homeowners realize — and it causes real damage. Yurii's team checks for signs of activity and can install protective guards to keep your system secure.

A professional clean using the right equipment and technique for your panel type and roof setup. Only recommended if the inspection shows it will make a measurable difference to your output.

Whatever they find, you'll get a straight answer. If nothing needs doing, they'll tell you that too. The goal isn't to sell a service — it's to make sure your system is running at its best.

Not necessarily — and we won't pretend otherwise. We recently reviewed production data across our client portfolio and identified specific systems where the numbers suggest cleaning would make a meaningful difference. If your year-one production is more than 10–15% higher than your most recent annual production, and you have a flat or near-flat roof in D.C., you're a strong candidate. The free inspection will tell you for sure.

That's the standard we hold ourselves to. We won't recommend a cleaning unless we believe the resulting increase in production — through both energy bill savings and additional SREC credits — will cover the cost within one year. If the math doesn't work, we'll tell you.

None. The inspection is free and comes with no pressure to purchase anything. If cleaning isn't needed, EcoSun Wash will tell you so.

Flat roofs are more susceptible to particulate buildup than tilted installations because they don't benefit from natural rain runoff. If you have a flat or near-flat roof in an urban area and your panels have never been inspected, an annual check-in is a sensible precaution.

Monitoring is a great sign — but it doesn't always tell the full picture. Gradual soiling causes gradual efficiency loss, which can be hard to detect without a year-over-year baseline comparison. A physical inspection confirms what the data can't always show. If you pull your all-time production report and notice more than a 10–15% decline from year one to your most recent year, that's worth investigating.

No. Sustainable You receives no compensation from EcoSun Wash. We partnered with them because we believe their work is in our clients' best interest — and because the honest answer to the cleaning question is more nuanced than we initially communicated.
