SECTION 01
The business in brief
Solar owners bought a machine that prints money from sunlight - and dust, pollen and bird droppings quietly tax it 15–25% a year. You sell the recovery: a pure-water (deionized) clean that leaves zero spotting, a before/after output reading, and an inspection report their warranty paperwork loves. Residential cleans run $150–$350; commercial arrays run $800–$3,000 per visit.
The channel strategy writes itself: solar installers need post-warranty service revenue and hate climbing roofs for $200 jobs. Become the referral partner for three regional installers and their 2,000-customer base becomes your pipeline, warm-introduced.
SECTION 02
How to execute, step by step
- 1
Buy a pure-water reach system
DI-fed brushes + poles reach 2–3 stories from the ground - most residential work never needs roof walking. $3k–$6k equipped.
- 2
Add output verification to every job
A clamp-meter reading before/after plus inverter screenshots turns a cleaning into a documented performance service worth premium pricing.
- 3
Get insured for roof work properly
GL policy with solar-equipment coverage explicitly named. Installers will ask for the certificate before referring anyone.
- 4
Price per panel with package anchors
$8–$12/panel is the market standard; 'clean + inspect + bird-guard check' bundles at 1.6× the base price.
- 5
Sign installer referral agreements
Offer installers a per-job referral fee or white-label service for their maintenance-plan subscribers - recurring revenue they can resell.
- 6
Sell annual maintenance plans
Two cleans plus one inspection per year, billed as a subscription. Plans convert 30–40% of one-time customers and double lifetime value.

DEMAND AHEAD OF TRAINED SUPPLY IN MOST METROS
The installed base is the story: every year adds a million-plus rooftops that exit installer warranty within 5–10 years and need independent service. Supply is thin - most pressure-washers lack pure-water systems and documentation habits. In sunbelt metros, operators report 3–4 week booking lead times with zero paid advertising, purely on installer referrals and Google.

Ground-based reach systems, named coverage, and photo documentation before touching anything.
Installer referral concentration
Keep 3+ partners and a direct-to-homeowner channel so no single source exceeds 40%.

Annual plans smooth revenue; schedule commercial arrays in high-soiling months.

SECTION 08
How to start a solar panel cleaning business - FAQ
A ground-based pure-water setup with insurance and marketing typically runs $4,500–$12,000 - far cheaper than most home-service startups because no vehicle beyond a van is required.
Market standard is $8–$12 per panel, with a $150–$200 minimum. Inspection bundles and bird-guard checks lift average tickets to $250–$400 residential.
Search demand is up ~57% YoY while trained supply lags. With 14M+ US installations aging out of warranty, most metros can support several dedicated operators.
