How to start a solar panel cleaning business

A solar panel cleaning business is one of the lower-cost trades to start: with an LLC, liability insurance, a deionized-water system, a water-fed pole, soft brushes, and roof-safety gear, you can open for $3,000 to $10,000. The pitch to customers is simple and honest — dirty panels lose output, so cleaning pays for itself in recovered electricity. The real challenge isn't the work; it's getting found, because the demand is local and most homeowners don't know the service exists until they search for it.

We build websites and run marketing for cleaning and home-service businesses, so the steps below are practical, and we'll be honest about the stage where you don't need us yet.

The steps, in order

  1. 1

    Form the business and get insured. An LLC, an EIN, and general liability insurance. Working at height around expensive equipment makes coverage essential, not optional.

  2. 2

    Buy the right equipment. A deionized/purified-water system, a water-fed pole with a soft brush, ladders, and roof-safety gear. Purified water is the key — it dries spot-free and won't reduce output.

  3. 3

    Learn safe technique. No pressure washers, no abrasive brushes — both can scratch panels and void warranties. Soft brush, purified water, and care around the wiring.

  4. 4

    Set services and pricing. Residential cleanings, recurring maintenance plans, and commercial or solar-farm contracts. Residential jobs commonly run $150–$400; commercial is priced per panel or per array.

  5. 5

    Get found: a profile, reviews, before/after photos, and installer referral partnerships.

What it actually costs to start

Residential start

$3,000–$10,000

LLC and insurance, a purified-water setup and water-fed pole, soft brushes, ladders and safety gear, and a website. The lean way to start with low overhead and learn the work before scaling.

Commercial-ready

$15,000–$40,000+

A wrapped vehicle, a larger purified-water tank and reach system, possibly robotic or rotary tools for big arrays, and a second technician. Worth it once you've landed recurring commercial or solar-farm contracts that justify the gear.

How to get your first clients

Demand is local and most homeowners don't know the service exists. The cheapest, fastest wins:

When you don't need us yet

If you haven't cleaned your first array, don't pay anyone for SEO. Get insured, buy the gear, and land a few jobs through installer partnerships and your network first — a free Google profile and a one-page quote-request site are plenty to start. We'd rather you spend on a purified-water system than on us.

Once jobs are repeating and you want inbound quote requests, a real site and local SEO are how you grow. That's where our Start Getting Leads plan ($249/mo: site + AI lead capture) and Grow in Google plan ($597/mo: adds the SEO engine and attribution) fit.

What equipment do you need?

A deionized/purified-water system, a water-fed pole with a soft brush, and roof-safety gear. Purified water dries spot-free. Pressure washers and abrasive brushes can damage panels, so they're avoided.
