About This Site
What this is, what it is not, where the information comes from, and why none of it is trying to sell you anything.
JP Solar Clean is an independent reference site covering commercial solar panel cleaning in the desert Southwest. It exists because the information available on this subject is almost entirely written by people selling the service, and that shapes what gets said.
A contractor’s website will tell you how often to clean. It will not tell you that cleaning sometimes does not pay for itself, or that the most common reason a clean fails in Las Vegas is the contractor’s own water supply, or that the interval they recommend may have more to do with their scheduling than with your roof.
This site can say those things because it has nothing to gain from you hiring anyone.
What This Site Does Not Do
Being clear about this matters more than anything else on the page.
- We do not clean solar panels. There is no crew, no equipment and no service to book.
- We do not quote jobs or arrange contractors. If you need work done, the guides explain what to look for — the hiring is yours to do.
- We do not accept payment for placement. No contractor has paid to be mentioned here, and none can.
- We do not take commission on work. Nothing here is written to push you toward a purchase.
If that changes — if this site ever carries advertising or any other form of paid placement — it will be stated plainly on this page rather than buried in a footer.
Where the Information Comes From
Everything here is compiled from published sources rather than from field experience. That distinction is worth stating openly, because it determines what this site is good for and what it is not.
- Module manufacturers’ published cleaning and maintenance specifications
- Peer-reviewed research on photovoltaic soiling and its effect on output
- Published climate and water quality data for the regions covered
- Industry technical documentation on cleaning methods and equipment
- Occupational safety requirements as published for rooftop work
Where a claim depends on local conditions, it is framed as something to verify against your own site rather than presented as a fact about your building. Where something is genuinely uncertain — and soiling loss figures are highly uncertain — that is said rather than smoothed over with a confident number.
Limitations
This is a reference site, not a consultancy, and it has limits worth knowing about.
Nothing here can tell you what your specific array needs. That comes from your own generation data and from someone standing on your roof. What this site can do is help you ask better questions and recognise a poor answer.
Nothing here is legal, safety or engineering advice. Regulations governing rooftop work, and the terms of your panel and roof warranties, are your responsibility to verify against the actual documents.
Information goes out of date. Prices shift, methods improve, and regional conditions change. If something here is wrong or has aged badly, tell us — corrections are welcome and they get made.
Coverage
The focus is Arizona and Nevada, because the desert Southwest combines dense commercial solar with unusually difficult soiling conditions — and because the difference between a good and a bad cleaning method matters more here than almost anywhere else.
More metros are added over time. If there is a market you would find useful to see covered, that is worth sending through.
Get in Touch
Corrections, missing information, or a market you would like to see covered — all welcome. If you work in the industry and think something important has been left out, that is particularly worth hearing.
