The Problem
Solar panels are rated for peak conditions — but real-world conditions include pollen, dust, bird droppings, tree sap, and film buildup. Even a light haze across your panels is cutting into your monthly output and pushing your payback period further out.
A typical 10kW residential system losing 20% output = roughly 2,000 kWh/year of missed generation. At average SC electricity rates, that's real money left uncollected.

FAQ
No — as long as the cleaning is done correctly. Most solar panel warranties require that cleaning be performed with soft tools, pH-neutral solutions, and no high-pressure water. That's exactly how we work. We never use methods that could invalidate your manufacturer's warranty.
Rain helps, but it's not enough. Rain can rinse loose dust, but it leaves mineral deposits from tap-quality water as it evaporates — the same reason windows look worse after rain without professional cleaning. Pollen, bird droppings, sap, and baked-on grime require manual removal. Studies consistently show panels in rainy climates still lose 5–15% output without periodic professional cleaning.
We schedule cleanings in the early morning or late afternoon when panels are cooler. Cleaning hot panels (mid-day peak sun) with cold water can cause thermal shock and micro-cracking in the glass. We never clean panels at peak operating temperature — it's one of the most common mistakes DIYers make.
It depends on how dirty your panels are. Lightly soiled panels typically see a 5–10% improvement. Heavily soiled or neglected panels can recover 20–30% or more. You should see the difference in your next utility bill or inverter monitoring app within days of cleaning.
For most single-story homes we can reach panels from the roof edge using extension poles without walking the roof surface. For two-story homes or complex roof layouts, we may need limited roof access. We always use soft-soled footwear and take care around shingles. Ground-mount arrays are fully accessible from ground level.
A typical residential system (20–30 panels) takes 60–90 minutes. Larger systems or heavily soiled arrays take longer. We'll give you an accurate time estimate when we quote based on your panel count, system layout, and roof pitch.
Absolutely — and most customers bundle them to save on a single visit. We can clean exterior windows, gutters, and solar panels in one trip, which is more efficient and saves you the cost of separate scheduling fees. Ask us about combo pricing when you reach out.
