Questions

How are companies ordered?

Ordered by a published score: one point for each of the 8 services a company lists on its own website, plus one point for each of 8 facts you can check there. No company can pay for its position or a badge.

Why are there no reviews or star ratings?

Reviews are easy to fake and hard to verify, so this site does not publish them. Every company is scored instead on facts you can check on its own website, such as whether it shows a license number, publishes prices or offers a written guarantee. The same method applies to every company.

Can a company pay to rank higher?

No. Listings, scores and order are free and cannot be bought. The publisher, Backroom Ops, also sells marketing help to businesses; buying it has no effect on any listing or score.

What does solar panel cleaning cost?

15 of the 40 companies we reviewed publish at least one price on their own websites, often per panel with a minimum charge. Every one is on the published prices page, with its source page.

Why does the water matter?

Some cleaners say on their websites that purified water dries without leaving mineral spots or residue on the glass. 34 of 40 companies say they clean with purified, deionized or reverse-osmosis water. Each company's page quotes its own words on method.
