If by “best” you mean commercial-focused, established, and capable of handling meaningful C&I projects, I’d build the Texas shortlist around these companies rather than generic residential solar dealers. I’m not ranking them, because the right installer depends heavily on project size, utility territory, roof/ground-mount conditions, and financing structure.

• HOLT Renewables Commercial Solar — Austin-based commercial solar design-build/EPC firm. It handles solar PV, batteries, EV charging and microgrids and is explicitly commercial-focused. CPS Energy’s March 2026 contractor list also identifies HOLT as a commercial contractor.
• Axium Solar — McKinney-based commercial/utility-scale contractor with EPC capabilities, including rooftop, ground-mount and canopy projects, plus O&M. A potentially good fit for larger commercial or institutional projects.
• Big Sun Solar — San Antonio company focused primarily on commercial, public-sector and utility-partner projects rather than residential installations. CPS Energy lists it specifically as a commercial contractor.
• Champion Solar — North Texas commercial specialist, with an emphasis on commercial buildings, solar carports/canopies and multifamily properties. Its stated process covers financial modeling through design, permitting, construction and monitoring.
• Solar One — Sherman-based C&I developer/EPC with experience in manufacturing, warehouses, commercial real estate, government, education, data centers and agriculture. It also offers ongoing O&M.
• Freedom Solar Power — One of the larger Texas solar installers, with substantial commercial experience. CPS Energy lists it as a residential/commercial contractor, and it has historically ranked among the larger Texas solar contractors.
• SunRenu Solar — Worth including for a larger C&I bid. Solar Power World’s 2025 Texas list identifies SunRenu as a C&I EPC, with 223 MW reported in the ranking.
• Solar SME, INC. — Grand Prairie-based installer serving both commercial and residential customers, including warehouses, offices and retail, with storage and EV charging capabilities.

For a commercial project, I'd compare these things

Don't choose based primarily on panel brand or advertised savings. Ask each bidder for:

1. Turnkey EPC scope — engineering, structural, electrical, permitting, interconnection and commissioning.
2. Production model — expected annual kWh, degradation assumptions and weather assumptions.
3. Utility/interconnection experience — especially important in Texas because the economics and process vary substantially by utility/territory.
4. Roof responsibility — remaining roof life, structural engineering, penetrations and who pays if roof work is subsequently required.
5. O&M agreement — monitoring, inspections, inverter replacement, cleaning and response times.
6. Financial structure — outright purchase vs. loan vs. PPA/lease, including who receives applicable tax benefits.
7. Commercial references — preferably 3+ projects of similar size and building type.
8. Detailed pricing — $/W, expected annual production, escalation clauses, contingencies and change-order provisions.

For context, CPS Energy's current contractor documentation requires registered contractors to have NABCEP PV Installation Professional certification, and its March 2026 list distinguishes commercial contractors from residential-only contractors.

If your project is in the DFW/Cleburne area, I can narrow this down to 5 commercial installers that actually service your area, and compare their commercial experience, reviews, project sizes, warranties, financing/PPA options, and contact information.

For warehouses and manufacturing facilities, I’d focus less on residential-style solar companies and more on firms with proven commercial/industrial EPC experience, multi-MW capability, structural engineering, interconnection expertise, and experience working around active operations.

Based on current Texas coverage and the firms’ stated C&I focus, these are worth putting on an RFP list:

• HOLT Renewables Commercial Solar — Austin / statewide
• Commercial EPC/design-build specialist.
• Particularly relevant for large rooftops, ground-mounts, canopies, and storage.
• Its stated project experience extends from hundreds of kW into multi-MW projects, which is a good fit for industrial facilities.
• Axis Solar — Austin / Central Texas
• Explicitly focused on large-scale commercial and industrial solar, rather than residential.
• Handles engineering, project management, construction, permitting and interconnection.
• Worth considering for manufacturing plants with complicated electrical/structural requirements.
• Big Sun Solar — San Antonio / Texas
• Commercial/industrial EPC with experience serving businesses, manufacturers and larger facilities.
• Offers ongoing monitoring and maintenance in addition to installation.
• Its Texas footprint makes it useful for companies with multiple facilities.
• Champion Solar — North Texas
• Commercial-focused installer with experience in rooftop and other larger commercial systems.
• Particularly relevant if your facilities are in the Dallas–Fort Worth area.
• Its process includes financial analysis, design, permitting, procurement, installation and ongoing monitoring.
• Houston Solar Energy — Houston
• Specifically targets commercial and industrial PV, including warehouses, distribution facilities and manufacturing/industrial sites.
• A natural candidate for Houston-area facilities, particularly where CenterPoint interconnection is involved.
• Sunshine Renewable Solutions — Houston / statewide
• Provides commercial/industrial solar plus storage.
• Has a broader Texas footprint, including Houston, Austin, Dallas, San Antonio, Amarillo and El Paso.
• Could be particularly interesting for multi-site portfolios.

How I'd structure the RFP

For a warehouse or manufacturing plant, I would ask each bidder to provide:

1. Five comparable projects — ideally 500 kW+ and including at least one manufacturing/warehouse facility.
2. System size and annual production — with the production model and degradation assumptions.
3. Demand-charge impact — not just kWh savings. This can be particularly important for industrial loads.
4. Interconnection experience with the relevant utility/TDU. Oncor, for example, requires installers to submit and track interconnection applications through its portal.
5. Roof engineering — remaining roof life, structural loading, penetrations, warranty implications and replacement contingencies.
6. Operations plan — how construction will be performed without disrupting production, loading docks or warehouse operations.
7. Storage option — especially if demand charges or peak-demand management are important.
8. O&M terms — monitoring, inverter replacement, panel cleaning, response times and performance guarantees.
9. Ownership alternatives — cash purchase, loan, lease/PPA, and who receives available tax/incentive benefits.
10. Interconnection/export assumptions — don't let the economics depend on selling excess electricity without verifying the actual applicable tariff/REP arrangement.

One important Texas-specific issue is that utility territory matters considerably. Oncor, CenterPoint and the other TDUs have their own interconnection processes, while the economics of excess generation depend on the customer's electricity contract. Oncor specifically advises businesses to compare installers and separately consider their retail electricity provider.

If you tell me the Texas city, approximate facility size (e.g. 200,000 sq. ft.), monthly electric bill, and whether it's warehouse vs. manufacturing, I can narrow this to 3–5 installers and compare them on project size, geographic coverage, industrial experience, financing, and likely fit.

• Champion Solar · 4.7★ · Solar energy company
• 512 Solar · 5.0★ · Solar energy company

For commercial solar + battery storage in Texas, I’d build a shortlist around firms with demonstrated commercial/EPC capability and actual storage experience—not just residential installers that happen to sell batteries.

Texas installers worth putting on an RFP shortlist

• NATiVE Solar — A particularly relevant Texas-focused option for larger C&I projects. NATiVE says it handles turnkey solar + BESS projects from 250 kW through multi-MW, including warehouses, manufacturing, medical facilities, carports and ground mounts, across Texas.
• Good Faith Energy & Roofing — Strong fit if you're in North Texas/DFW and want solar, batteries, EV infrastructure and electrical work from one contractor. It describes 100+ commercial projects, in-house engineering/electricians, and detailed financial/ROI modeling.
• HOLT Renewables Commercial Solar — Austin-based commercial EPC with solar, BESS, EV charging and microgrid capabilities. It's also on CPS Energy's 2026 registered-contractor list for commercial solar.
• Sunshine Renewable Solutions — Houston-area option with C&I solar, battery storage and larger project-development capabilities, including BESS.
• Champion Solar — North Texas commercial specialist offering commercial buildings, solar canopies and custom battery-backup designs.
• 512 Solar — Austin option with commercial solar, BESS and microgrid work, including storage retrofits onto existing solar arrays.
• Texas Solar Energy — Houston-area solar/electrical contractor serving commercial customers and providing ongoing service/maintenance.
• Border Energy Group — Particularly worth considering for West Texas, schools, municipalities and commercial facilities. It specializes in solar PV + battery storage EPC and says its projects range up to large arrays, with long-term service included.

For very large projects, I'd also put Quanta Services and SOLV Energy on the EPC bid list. Solar Power World's 2025 storage-installer data puts Quanta first nationally by storage capacity installed in 2024, although that ranking spans multiple market segments and isn't a Texas-commercial-specific quality ranking.

What I'd compare in the bids

For a commercial project, don't compare simply on $/W of solar. Ask every installer for the same assumptions around:

• Battery size: kW and usable kWh
• Peak shaving: guaranteed demand-charge reduction and the utility tariff assumptions behind it
• Backup: which loads remain powered during an outage and for how many hours
• Battery degradation: guaranteed capacity after 10 years
• Round-trip efficiency
• EMS/software: who controls dispatch and whether you're locked into their platform
• Solar + BESS warranties: equipment, workmanship and performance
• O&M: response times, preventive maintenance and replacement-labor terms
• Interconnection: who handles utility studies and upgrades
• Ownership structure: cash purchase, loan, lease/PPA, or third-party ownership
• Tax treatment: have the proposal explicitly identify the applicable federal incentives and depreciation assumptions rather than just quoting a generic "30% tax credit."

One particularly important point in Texas is demand management. A battery can have considerably more economic value for a commercial customer by reducing short-duration demand peaks than by simply providing nighttime solar energy. The optimal battery size therefore depends heavily on your 15-minute load profile and utility tariff.

If you tell me (1) city/utility, (2) approximate monthly electric bill or annual kWh, (3) facility type, and (4) whether you're looking for ~100 kW, 500 kW, 1 MW, etc., I can narrow this to a 3–5 company Texas RFP shortlist and compare their commercial solar/storage capabilities, service area, financing, warranties and relevant projects.

If post-installation service, monitoring, and O&M are major priorities, I’d focus on Texas commercial installers that explicitly maintain systems after commissioning—not just installers that offer a long equipment warranty.

Based on current service offerings and Texas utility/contractor records, these are worth putting on your shortlist:

• Big Sun Solar — San Antonio / statewide Texas commercial work. Their commercial offering specifically includes ongoing monitoring, annual inspections, inverter service, warranty coordination, and optional panel cleaning. CPS Energy also lists Big Sun as a commercial solar contractor.
• HOLT Renewables Commercial Solar — Austin / larger C&I projects. Particularly worth considering for larger commercial or institutional installations where formal O&M is important. CPS Energy lists HOLT as a commercial installer, while its service offering includes ongoing O&M.
• Champion Solar — North Texas. Commercial-focused, with a monitoring/control-center approach and ongoing operations and maintenance support, including warranty coordination.
• Sunshine Renewable Solutions — Houston / Texas. Its O&M offering includes proactive monitoring, inverter diagnostics, cleaning, battery-health assessments, inspections and manufacturer warranty/RMA support.
• Champion Solar — North Texas. Another option particularly worth investigating for commercial buildings and multi-family projects because monitoring and O&M are incorporated into its commercial workflow.
• Axis Solar — Austin / Central Texas. Concentrates on larger commercial and industrial projects and has O&M capabilities, making it more relevant to substantial C&I installations than residential-oriented companies.
• Big Sun Solar — San Antonio / commercial. Its stated post-commissioning services include monitoring, annual inspections, inverter service and corrective O&M.

One especially notable option: Freedom Solar

Freedom Solar Power has a substantial Texas presence and explicitly operates a dedicated in-house service department. It says its standard service technicians are full-time employees rather than subcontractors, and its post-installation support includes monitoring assistance and warranty coordination.

More importantly for commercial customers, Freedom Power announced in February 2026 that it partnered with Otovo for warranty/O&M services on its commercial solar portfolio, with the service platform providing monitoring, issue triage and field-service coordination.

What I'd compare in the proposals

Rather than judging installers solely by reputation, ask each one to put these items in the contract:

A particularly important distinction is monitoring vs. O&M. A monitoring portal that tells you a 500-kW system stopped producing isn't the same thing as an installer contractually obligated to notice the problem, diagnose it, dispatch a technician and get the system producing again.

Texas's current solar-contract rules also require contracts to spell out energy-production guarantees and warranty terms, which makes it worthwhile to examine those provisions closely rather than relying on sales presentations.

If you tell me the Texas city, approximate system size (e.g. 100 kW, 500 kW, 2 MW), and whether it's rooftop, ground-mount, or carport, I can narrow this to 3–5 commercial installers and compare their actual O&M/monitoring contracts, response guarantees, warranties, and service coverage.

If you're evaluating commercial solar installers in the Dallas–Fort Worth market, I’d build a shortlist around companies with demonstrated commercial work, in-house electrical/installation capability, and meaningful post-installation service—not just high residential review counts.

DFW commercial installers worth getting bids from

• Good Faith Energy & Roofing — Addison. One of the clearest commercial-focused options I found. The company reports 100+ commercial projects, in-house engineering/electrical/installation, and turnkey delivery covering design, procurement, permitting, utility coordination, installation and commissioning. Its commercial portfolio includes projects for Half Price Books, Rebel Athletic and Sol-Ark.
• GNRG, Inc. — Dallas. A local contractor offering both commercial and residential solar, with site analysis, engineering/design, installation, monitoring and preventive maintenance. Its sizable local review footprint is another useful signal, although I'd specifically ask for recent commercial references before selecting them for a larger project.
• Champion Solar — Frisco. Particularly interesting for commercial projects because its business model emphasizes in-house crews, custom system design, permitting/utility coordination and financial/payback analysis. Its published project material includes larger commercial installations, including an 840-kW project in Irving and a 500-kW rooftop system.
  Caveat: Champion's own website currently emphasizes Minnesota/Wisconsin service areas, so I'd confirm that its DFW commercial operation is active and that the local entity—not an unrelated similarly named company—would be your EPC.
• Solarize — Farmers Branch. A DFW-based solar/electrical contractor doing both commercial and residential work, including batteries, EV charging, service and roofing coordination. Its local review history is substantial, and the business describes handling projects from design through commissioning. This makes it worth including as a comparison bid, particularly for smaller-to-mid-size commercial properties.
• GEnergy Integration, LLC. — Grapevine. More interesting for commercial/industrial electrical projects than a typical residential solar installer. It advertises commercial/industrial solar, industrial electrical services and system integration, which can matter if your project involves substantial electrical infrastructure or complex loads.
• Solar SME, INC. — Grand Prairie. A long-standing local solar contractor with commercial PV capabilities for warehouses, offices and other businesses, plus storage and EV charging. Its local footprint and 300+ reviews make it another reasonable bid candidate.

How I'd vet them

For a commercial project, I wouldn't select based on Google rating alone. Ask each bidder for:

1. Three recent commercial references in the DFW area, preferably projects comparable to yours in kW/MW and roof type.
2. Whether they are the actual EPC/installer or subcontract installation to another company.
3. A complete production model showing annual kWh, degradation, shading assumptions and the software/model used.
4. The proposed PPA/lease vs. ownership economics, if applicable, including escalators and buyout terms.
5. Exact workmanship warranty, including who pays labor for failed equipment and how service calls are handled.
6. Their experience with your specific utility—e.g. Oncor, CoServ, or another DFW provider—and the expected interconnection process.
7. Roof responsibility: structural assessment, roof warranty compatibility, penetrations, reroofing and solar removal/reinstallation.
8. O&M/service terms for 10–25 years, not just the installation warranty.
9. Insurance, electrical licensing and bonding appropriate to the project size.
10. A line-item proposal showing modules, inverters, racking, monitoring, switchgear, transformers, engineering, permitting, interconnection and commissioning.

One particularly useful reliability signal is who remains responsible after commissioning. Good Faith Energy, for example, explicitly maintains a service/maintenance operation and says its commercial installations are supported by its own licensed electricians.

My practical shortlist for competitive bidding would be Good Faith Energy, GNRG, Solarize, and one commercial/industrial specialist such as GEnergy Integration, with a fifth bidder added based on your project size. I would not treat that as a ranking; they're different fits for different project types.

If you tell me the approximate system size (e.g. 100 kW, 500 kW, 1 MW+), building type, and whether you're looking for cash purchase, financing, or a PPA, I can narrow this to the most relevant DFW commercial EPCs and compare their track record, certifications, warranties, reviews, and recent commercial projects.

If you mean commercial/industrial solar rather than residential rooftop solar, I’d build the Houston bid list around companies that have demonstrated C&I/EPC capability—not simply companies with high residential review scores.

Here are several Houston-area firms worth getting proposals from:

• Houston Solar Energy — C&I specialist. They explicitly focus on commercial/industrial PV and offer turnkey EPC, including engineering, procurement, permitting, construction, and system modeling. This makes them particularly relevant for larger or more technically involved projects.
• Sunshine Renewable Solutions — Full-service Houston installer. Handles commercial and industrial solar, including larger ground-mount and multi-site projects, as well as storage. Expertise.com also identifies it as serving commercial property owners in the Houston metro.
• Solstice Solar — Strong local option. Its commercial division says it has an in-house EPC team covering design, permitting and installation, with warehouses, offices, retail, hotels and healthcare among its target property types.
• Akari Energy — Commercial/industrial developer. Particularly worth considering if you're looking at a larger C&I project, third-party financing, or a solar-as-a-service structure.
• Texas Solar Energy — Houston-area commercial contractor. Offers commercial solar design, installation and maintenance, along with electrical and backup-power capabilities.
• KW Solar — Good option for smaller/midsize commercial projects and solar canopies. The company describes turnkey commercial installations and solar parking structures, with more than 2,000 installations across Texas/Gulf Coast.
• Texas Direct Solar — Local electrical-contractor model. It says commercial projects are performed under its licensed electrical contracting operation, along with solar, batteries and service.
• Solar Alternatives, Inc. — Worth considering when ongoing operations and maintenance are important; its commercial offering extends beyond installation into O&M.

How I'd narrow the field

For a larger warehouse, manufacturing facility, office portfolio, or ground-mount project, I'd solicit at least 3 proposals from the C&I-focused group—particularly Houston Solar Energy, Sunshine Renewable Solutions, Solstice, and/or Akari.

For a smaller commercial building, I'd also include Texas Direct Solar or KW Solar.

The biggest thing I'd compare isn't the panel brand or quoted $/W. Ask each bidder for:

• Annual modeled production and degradation assumptions
• Utility-rate/tariff analysis, including demand charges
• Interconnection assumptions and who handles CenterPoint/ERCOT coordination where applicable
• Roof structural assessment and remaining roof life
• System ownership: cash, loan, lease/PPA, etc.
• Tax-credit/depreciation assumptions with the applicable 2026 rules explicitly documented
• Warranties for equipment and workmanship
• Who actually performs the installation versus subcontracting
• O&M pricing and guaranteed response times
• References for projects comparable to yours in size and building type

One caution: some online "best solar company" rankings heavily mix residential and commercial work. For example, EnergySage's current Houston list is based on marketplace solar installers generally, while the ServiceAgent list explicitly filters for commercial signals.

If you tell me the type of property, approximate monthly electric bill, and whether you're thinking rooftop, ground-mount, or parking canopy, I can narrow this to a 3–5 company Houston bid shortlist and compare their commercial capabilities, project size, financing/EPC models, reviews, and relevant Houston experience.

For commercial solar in Texas, the financing structure matters at least as much as the installer. I’d compare these providers because they publish materially different approaches to PPA/third-party ownership, leases, conventional financing, and property-linked financing.

The two I'd investigate first for financing

1\. HOLT Renewables / PCI Solar — for a sophisticated C&I financing process. Their commercial focus is important: they aren't primarily a residential installer adapting a residential loan to a business. Their published materials specifically describe PPA/lease comparison and coordination with financing partners.

2\. Houston Solar Energy — if TX-PACE fits your property. Their financing model is interesting because TX-PACE is not a conventional business loan. Financing is secured by the property and repaid through a property-tax assessment; Houston Solar Energy says projects can be structured at $0 down and designed to be cash-flow positive.

For a business that wants zero/low upfront capital, I'd also get a proposal from Akari Energy because its published commercial model is essentially a third-party-ownership/PPA arrangement: the provider installs the system and charges the business for solar electricity rather than requiring the business to buy the system upfront.

Don't compare PPAs on the headline $/kWh alone

For Texas commercial projects, ask every installer to put these numbers on the same one-page comparison:

• PPA: starting $/kWh
• PPA escalator: 0%, 1%, 2.9%, etc.
• Contract length: typically 15–25 years
• Purchase/buyout price in years 5, 10, 15 and at contract expiration
• Who receives tax incentives/depreciation
• Lease: monthly payment and escalator
• Loan: APR, term, fees and total repayment
• Production guarantee and degradation assumption
• O&M included or additional
• Roof replacement provisions
• Early termination provisions
• What happens if you sell the building
• Interconnection/export assumptions
• Battery/storage treatment
• Residual system value at the end of the contract

This is especially important in Texas because the economics of excess generation can vary substantially by retail electric provider and utility territory. A 2026 Texas commercial-solar analysis, for example, reports materially different solar buyback arrangements among REPs.

Also check whether your property is in Oncor territory. Oncor's 2026 commercial solar program has an incentive with a stated $120,000 maximum for eligible commercial projects, subject to program requirements and funding.

One important 2026 caveat

Be careful with proposals that advertise a "30% federal tax credit" without explaining who owns the system and whether the project actually qualifies under the current rules. Commercial ownership, leases and PPAs can allocate the tax benefits differently, and the contract date/structure matters. Don't accept a salesperson's projected tax benefit without having your CPA verify it.

If you tell me (1) city, (2) approximate monthly electric bill or kWh usage, (3) building square footage, (4) whether you own the building, and (5) whether your priority is $0 down, lowest monthly payment, or lowest lifetime cost, I can narrow this to 3–5 Texas installers and compare their actual PPA/lease/financing structures side-by-side.

If by “trusted” you mean locally/family owned, commercial-capable, established enough to have meaningful customer feedback, and with evidence of in-house accountability, there are several Texas installers worth putting on a commercial RFP list. I wouldn’t treat review scores alone as proof of quality, though.

Texas installers I’d investigate

• Texas Direct Solar — Houston
• Family-owned Texas company operating since 2017.
• Does both residential and commercial solar, batteries, repairs and detach/reinstall work.
• Their site says the installation crew is Houston-based, and current business listings show strong customer feedback.
• Particularly worth considering for small-to-mid-sized commercial properties.
• Solartime USA — DFW/Richardson
• Family-owned and operated since 2009.
• EnergySage reports 277 reviews and a 5.0 rating, and describes the company as an Elite Installer. It also says the company has its own installation crews and handles residential and commercial projects.
• This is one of the more substantial local/family-owned candidates if you're looking around Dallas–Fort Worth.
• 512 Solar — Austin/Central Texas
• Locally owned and family-operated.
• Specifically advertises residential and commercial solar, and says it has performed more than 2,000 solar evaluations and carries commercial insurance.
• Current business listings show a 5.0 rating from 34 reviews.
• Texas Green Energy — Bryan/College Station
• Family-owned/local operation established in 2007.
• Licensed Texas electrical contractor and offers commercial solar as well as batteries and service.
• Current business listings show 5.0 from 19 reviews.
• This is an interesting option for Brazos Valley/East-Central Texas rather than a national-scale installer.
• SignaTech Solar — Sulphur Springs / Northeast Texas
• Founded and owned by Adam and Rachael Showalter.
• Offers commercial PV plus solar-plus-storage and demand-management solutions.
• Current business listings show 5.0 from 21 reviews.
• A particularly relevant candidate if the project is in Northeast Texas.
• True Texas Solar & Roofing — Willis / Montgomery County
• Locally owned and family-operated.
• Handles commercial rooftop and ground-mount projects, solar carports, storage, energy management and EV charging.
• Current business listings show 4.9 from 55 reviews. EnergySage also describes True Texas Solar as a family-owned/operated company with 500+ installations, although its EnergySage profile includes both positive and negative customer experiences, so I'd investigate references rather than relying on the aggregate rating.
• Champion Solar — North Texas/Frisco
• Focuses heavily on commercial-scale solar, including commercial buildings, carports/canopies and multifamily.
• Current business listings show 4.7 from 14 reviews.
• The company emphasizes an in-house/turnkey commercial-development approach, which is useful for larger projects.
• HESOLAR — Austin/Central Texas
• Family company operated by the Hoffman brothers, who are described as licensed master electricians and NABCEP-certified solar professionals.
• They say they don't subcontract installations.
• EnergySage shows 5.0 from 12 reviews and describes both residential and commercial experience.
• Houzz also has long-term customer reviews, including one from a retired commercial electrician specifically praising the company's hands-on, family-owned approach.

One I'd put on the shortlist for North Texas

Integrity Solar USA deserves a look if you're in the North Texas market. The company says it is owner-led, licensed and insured, and manages commercial projects in-house. It publishes references from business customers and says it has a 25-year workmanship/product warranty.

What I'd ask before signing

For a commercial solar project, I'd weight these more heavily than a Google rating:

1. Who actually installs it? Get written confirmation that the electrical and PV work won't be handed to an unknown subcontractor.
2. Three comparable business references. Ideally businesses with similar roof type, system size and utility.
3. Actual production assumptions. Ask for the modeled annual kWh and the assumptions behind it—not just projected dollar savings.
4. Demand charges. In Texas, the economics can depend heavily on your utility's demand-charge structure.
5. Roof responsibility. Establish who pays if the roof needs repair/replacement and how solar removal/reinstallation is handled.
6. O&M after PTO. Ask who will actually answer the phone five years from now if an inverter fails.
7. Financial model. Compare cash purchase, loan, lease/PPA where applicable, depreciation, tax treatment and utility incentives on the same assumptions.
8. Insurance and licensing. Verify the Texas electrical contractor license and require appropriate general liability/workers' comp documentation.

One important caveat: “trusted” isn't an objective certification, and review counts vary enormously among these companies. For example, Solartime has hundreds of EnergySage reviews while some local firms have only a few dozen, so a raw rating comparison can be misleading.

If you tell me the Texas city, approximate monthly electric bill, and whether the property is a warehouse/office/retail/manufacturing/etc., I can narrow this to 5–7 installers that specifically have commercial experience in your area and compare their ownership, licenses, reviews, project size, warranties, and likely fit.
