Commercial Solar Suppliers & Installers in Texas
Texas has 400+ registered solar installation companies, but fewer than 100 specialize in commercial projects over 100 kW. The difference matters — commercial solar requires TECL licensing, flat-roof expertise, commercial-scale interconnection, and familiarity with the 30% ITC + MACRS tax stack. Use the free calculator below to get your system size, then we match you with 2-3 vetted commercial installers who work in your area.
Commercial vs. Residential Installers: Why It Matters
Hiring a residential installer for a commercial project is the #1 cause of project delays, cost overruns, and undersized systems in Texas. Commercial solar is a different discipline: flat-roof mounting (ballasted or attached), commercial-scale inverters (string or central), demand-charged utility tariffs, commercial structural loads, and tax paperwork (ITC, MACRS, depreciation schedules) that no residential installer handles.
| Capability | Residential Installer | Commercial Installer |
|---|---|---|
| System Size | 5-25 kW | 50 kW - 5 MW+ |
| Roof Type | Asphalt shingle | Flat TPO / EPDM / metal |
| Electrical | 200A residential | 480V 3-phase commercial |
| Tariff Handling | Simple net metering | Demand charges + ToU |
| Tax Paperwork | 25D (homeowner ITC) | Section 48 ITC + MACRS |
| Typical License | Residential electrical | TECL Master Electrician |
How We Vet Commercial Solar Suppliers
These are the six criteria we use to qualify every installer before matching you. Ask any supplier you're considering for documentation on all six — reputable ones will produce them immediately.
NABCEP Certification
PV Installation Professional — the industry gold standard. Confirms the installer has passed rigorous technical exams and follows NEC code.
Texas TECL License
Master Electrician license issued by Texas Department of Licensing and Regulation. Required for all commercial solar interconnections.
$1M+ Liability Insurance
General liability + workers' comp. Confirms the company can cover damage during installation and worker injuries on your roof.
Commercial Experience
5+ years of Texas commercial installations at your building's scale. Commercial roofing, structural, and interconnection differ from residential.
Manufacturer Certifications
Tesla, Enphase, SolarEdge, Q-Cells, REC — certified installers get better pricing, warranty terms, and product support.
Production Warranty
10-25 year workmanship + 25-year panel production guarantee (minimum 90% of NREL PVWatts baseline). Anything less is a red flag.
