How Much Efficiency Are You Losing?
Research consistently shows that dirty solar panels can lose between 20–30% of their energy output.
For a typical 8 kW system in New Mexico, that could mean hundreds of dollars in reduced savings
annually — and the loss compounds if cleaning is deferred across multiple seasons.
The good news: a professional cleaning restores panels to near-original output levels. In most cases,
homeowners notice the improvement in their next monthly production report.
What Professional Solar Panel Cleaning Involves
Professional cleaning is different from hosing your panels off with a garden hose, which can leave mineral deposits and doesn’t address stubborn debris. SunState Solar’s trained technicians use specialized equipment and de-ionized water — which leaves no spots or mineral residue — to deliver a thorough, safe clean that maximizes sunlight absorption.
During a professional cleaning appointment, technicians also conduct a visual inspection of the full system, checking for:
• Loose or degraded wiring
• Signs of corrosion
• Cracked or damaged panels
• Mounting hardware issues
This combination of cleaning and inspection is one of the most cost-effective ways to protect your
investment and catch small issues before they become expensive problems.
How Often Should New Mexico Panels Be Cleaned?
Most solar manufacturers recommend at least one professional cleaning per year as a baseline. In
New Mexico, two cleanings per year is often more appropriate — one in late spring (before peak
summer production) and one after monsoon season ends in September or October.
The late spring window is particularly valuable: cleaning before June and July means your system enters its highest-production months at full efficiency, maximizing the savings during the months when your air conditioning is running hardest and your electricity bills are at their peak.
Areas with high dust exposure, nearby agricultural activity, or significant bird populations may benefit from more frequent service.
DIY vs. Professional Cleaning
Some homeowners attempt DIY panel cleaning, and while it’s possible to do without damaging panels,
there are real risks:
Safety:
Mexico’s environment, the impact is on the higher end of that range.
Is solar panel cleaning covered under my warranty?
Cleaning itself is typically the homeowner’s responsibility and is not covered under manufacturer
equipment warranties.
However, the visual inspection that accompanies a professional cleaning visit can catch warranty-eligible issues — making it a valuable part of your overall system maintenance routine.

Frequently Asked Questions: Choosing a Solar Company in New Mexico
Go to the New Mexico Regulation and Licensing Department (RLD) website and search the contractor license lookup tool. Search by license number or company name and verify that both electrical and general building classifications are active. If a company gives you a license number, run it before you sign anything.
An installation warranty covers any issues caused by the workmanship itself — roof leaks at penetration points, wiring problems, mounting failures. It’s separate from the manufacturer warranty that covers the panels and inverter. The industry minimum to look for is 10 years. SunState backs every installation with a 25-year warranty and a Lifetime Assurance Warranty — coverage that significantly exceeds that standard.
Yes. Getting 2–3 quotes lets you compare equipment, warranties, timelines, and pricing side by side. When comparing quotes, make sure each one is itemized — comparing a lump-sum quote to a detailed quote is comparing different things entirely. Ask each company the same 7 questions and see who answers with confidence.
Key red flags: inability to provide a verifiable NM license number, use of subcontractors for installation, no local physical presence, pressure to sign on the day of the consultation, vague or verbal-only pricing, and very few local Google reviews. National companies advertising heavily but with no local office are a consistent source of post-installation service complaints.
You can’t guarantee it, but you can improve your odds significantly. Look for companies with continuous local operation for 5+ years, a physical local office, strong recent Google review volume, and clear answers about who handles warranty service if the company is ever sold or changes. A 25-year warranty is only as good as the company standing behind it.
