Solar Panel Cleaning Service
Keep solar panels shining—recurring revenue by design
Solar panel cleaning services maintain residential and commercial solar arrays by removing dust, bird droppings, and debris. Dirty panels lose 15–25% efficiency. Customers pay $150–$400 for residential cleaning or $500–$2,500+ for commercial systems. The real opportunity: recurring contracts. Most solar panel owners prefer quarterly or semi-annual maintenance plans ($40–$150/month subscription), creating predictable recurring revenue. A solo operator can manage 20–50 residential accounts, generating $100K–$250K/year. The solar installation market is exploding (500K+ new systems/year in US), creating constant supply of potential customers.

How It Works
Technicians use soft-brush equipment, deionized water, and eco-friendly solutions to clean solar panels without damaging cells or coatings. One-time cleaning: customer calls for a spring/summer deep clean ($150–$400 residential, $500–$2,500 commercial). Subscription model: customers enroll in monthly or quarterly plans ($45–$150/month) for automatic semi-annual or quarterly visits. Revenue is split: 60% from subscriptions (recurring, sticky), 40% from ad-hoc jobs. Customer acquisition happens through: (1) direct outreach to solar installers (referral partnerships), (2) local SEO targeting 'solar panel cleaning near me', (3) solar installer job site visits.
