McKinney Electricity Prices
Electricity prices shape the value of every kilowatt-hour a McKinney household uses.
Texas residential electricity prices rose from 12.1¢ per kWh in 2021 to 14.9¢ in 2024. The U.S. average climbed from 13.7¢ to 16.5¢. These are statewide and national figures, not McKinney-specific rates.
For McKinney homeowners, solar panels can generate electricity at home and may reduce how much power a household buys from the grid. The impact depends on system production, energy use, and utility plan.
Over time, using less grid electricity may help limit exposure to changing energy prices. A solar system’s long-term value depends on installation costs, upkeep, output, and how local utility rules credit excess power.

McKinney Area Utility Providers
In McKinney, CoServ is the local utility provider in the available data. The latest figures provided are from 2023: CoServ’s rate was 12.8¢ per kWh, compared with 14.50¢ for Texas and 16.0¢ nationally.
CoServ’s 2023 rate was below both the state and national averages. These figures show how the listed local rate compared with broader benchmarks; they do not explain why rates differ, and 2024 utility data is not yet available.
For McKinney homeowners, solar can generate some of a home’s electricity, potentially reducing how much power is purchased from the utility. Its impact on electricity costs depends on household use and the solar system.

Texas Solar Incentives
McKinney homeowners may find state and local programs that help offset solar installation costs. See the solar incentives in Texas listed below.
Options include an Oncor project incentive of up to $9,000 through an approved provider, battery demand-response rewards from participating utilities, a Texas property-tax exemption for qualifying solar devices, and export compensation set by each retail electricity provider.
With LightReach solar leasing, Palmetto handles the commercial investment tax credit and passes savings through as lower monthly payments, which can simplify incentives; program terms and eligibility still matter.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Oncor 2026 Residential Solar Photovoltaic Incentive | Utility Solar Rebate / Performance Incentive | Oncor-served homeowners may qualify for a project-specific incentive of up to $9,000 for a new solar installation, with or without battery storage, through an approved participating provider. | Learn More |
| TXU Energy Battery Rewards | Battery Demand-Response Reward | Eligible TXU Energy customers with rooftop solar and an Enphase battery may receive a $150 digital reward card every six months while enrolled and meeting program requirements. | Learn More |
| Gexa Battery Benefits | Battery Demand-Response Payment | Published program information lists a $50 payment for each participating month for eligible Gexa customers with Enphase batteries who make their batteries available for peak-demand dispatch. | |
| Texas Solar Property-Tax Exemption | Property Tax Exemption | Texas Tax Code §11.27 exempts the portion of appraised value attributable to a qualifying solar energy device used primarily to produce and distribute energy for on-site use. | Learn More |
| Texas Solar Export Compensation and Net Metering Policy | Net Billing / Utility-Specific Export Compensation | Texas has no statewide net-metering mandate or uniform solar buyback rate; export compensation depends on the homeowner’s retail electricity provider and plan. | Learn More |
Oncor’s 2026 Solar Photovoltaic Program offers a variable, project-specific incentive of up to $9,000 for an eligible residential solar project. The incentive is paid to the participating service provider, so homeowners should obtain written confirmation of the amount that will be credited toward their project price.
The home must be in Oncor’s electric-delivery territory, and the project must use an approved participating provider and receive Oncor interconnection approval. The 2026 manual allows solar with or without storage; it limits residential system size to 20 kW DC or 75% of the site’s maximum demand over the prior 12 months, as applicable. Existing solar can make a site ineligible. Funds are limited, and the stated 2026 production-period deadline is November 30, 2026, so confirm availability and requirements before signing or beginning construction.
TXU Energy Battery Rewards offers a $150 digital reward card every six months to eligible enrolled customers, for up to $300 per year while they remain eligible. The program requires an eligible Enphase battery and rooftop solar; participants must keep at least 20% of battery capacity available under the stated program terms.
Participants make their battery available for dispatch during program events. TXU’s terms state that customers who do not participate in at least 90% of dispatch events may be unenrolled, and the customer must remain an active TXU Energy customer when a reward is fulfilled. Review current terms and confirm equipment eligibility before enrollment.
Published program information describes a $50 payment for each participating month for customers enrolled in Gexa Battery Benefits. The payment is tied to making an eligible Enphase battery available for Gexa’s peak-demand dispatch; it is not an upfront battery-purchase rebate.
Eligibility, enrollment availability, dispatch obligations, and payment conditions depend on the current Gexa program terms and the customer’s electricity plan. Confirm the details directly with Gexa before relying on the monthly amount. An official Gexa program link was not available in the supplied search results.
Texas Tax Code §11.27 provides a property-tax exemption for the increase in appraised value attributable to a qualifying solar energy device used primarily to produce and distribute energy for on-site use. This is not a cash rebate; it can reduce the taxable appraised value attributable to the qualifying equipment.
Homeowners generally apply through their county appraisal district using the Comptroller’s Form 50-123 and should check local filing procedures and documentation requirements. A battery’s eligibility may depend on whether it qualifies as part of a solar energy device and on the appraisal district’s application of the law, so do not assume every battery installation qualifies automatically.
Texas does not provide a statewide net-metering program or a uniform required buyback rate for residential solar exports. The financial value of electricity sent to the grid depends on the retail electricity provider and the specific plan available at the home, rather than being set by a single statewide solar credit.
Before choosing a plan, homeowners should review the written export-credit rate, how credits are calculated and carried forward, whether credits expire, and whether delivery charges or other fees apply. In Oncor territory, Oncor handles electric delivery and interconnection, while the retail provider determines the plan’s export-compensation terms.

How to Choose a Solar Installer in McKinney
Verify the license
Texas does not issue a separate general “solar installer” license. Non-exempt electrical work must be performed through a licensed electrical contractor, and covered residential solar contracts must provide for installation by one. Ask which licensed electrical contractor will do the work, and look up its license through the Texas Department of Licensing and Regulation (TDLR) license search. Starting September 1, 2026, residential solar retailers and salespeople generally must also register with TDLR, subject to exemptions. A sales credential does not replace the electrical-contractor license.
Look for certified installers
NABCEP credentials and manufacturer certifications can be useful additional points of comparison, but neither substitutes for the required electrical-contractor license. Ask which person holds each credential, what work or equipment it covers, and how you can verify it. Review NABCEP’s certification information, and ask the installer to explain any manufacturer certification it cites rather than treating a logo as a guarantee of quality.
Compare quotes the same way
Request written quotes with the same assumptions and compare each item, not just the advertised monthly payment:
- System size: installed capacity in kW, plus total price and price per watt.
- Equipment: panel and inverter brands and models.
- Expected production: estimated kWh per year and how the installer calculated it.
- Warranties: panel product and performance, inverter, workmanship, and roof penetrations; check who backs each one and how claims are handled.
- Project responsibilities: who obtains permits, schedules inspections, and submits the interconnection application.
- Payment: total cost or monthly payment, financing or lease terms, and any escalator. Compare the full payment terms, not a payment figure alone.
For context, Palmetto reports a median installed system of 8.9 kW and about 52 days from signing to installation. Those are Palmetto figures, not a promise or a substitute for comparing the scope and timeline in each written quote.
Permits, interconnection and your HOA
Building and electrical permits and inspections are handled by the local authority with jurisdiction; the office and requirements depend on the property location. Interconnection is handled through the electric utility serving the home, and co-ops and municipally owned utilities may have utility-specific requirements. Ask the installer to identify both parties and show who handles each step. The utility names supplied for comparison—Reliant Energy Retail Services, TXU Energy Retail Co, LLC, City of San Antonio – (TX), and Austin Energy—should not be assumed to serve a McKinney address; verify the utility for your home. Texas generally bars property owners’ associations from prohibiting or restricting solar devices, with statutory exceptions; see Texas Property Code §202.010(b)–(d). Ask how the installer will address any applicable HOA process.
Red flags
- Pressure to sign the same day or a quote that discourages comparing offers.
- No clearly identified licensed electrical contractor, or crews whose licensing and responsibility are unclear.
- Vague production estimates, large upfront deposits, or verbal promises missing from the contract.
- Promises of a federal homeowner tax credit for a 2026 purchase: homeowner credits ended December 31, 2025.
TDLR accepts complaints about electrical contractors’ solar installation or repair work and covered residential solar retailers or salespeople. For deceptive or misleading sales or other general consumer-protection allegations, homeowners can complain to the Texas Attorney General’s Consumer Protection Division; filing does not guarantee individual dispute resolution.
Palmetto is one installer you can compare, with a lease option through LightReach.
Leasing Solar Panels
For McKinney homes in CoServ’s service area, Palmetto LightReach offers a solar lease. A lease generally has a fixed monthly payment; a power purchase agreement (PPA), where available, charges for the electricity the system produces. Availability depends on your exact utility service and home.
With a lease, you can go solar without paying the full system cost upfront. Unlike a cash purchase, where you own the equipment and arrange and pay for maintenance, a LightReach lease includes system maintenance through Palmetto. Review the agreement for payment terms, coverage, and responsibilities.
Compare the tradeoffs in our guide to buying or leasing solar, and learn about the LightReach program.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

McKinney, TX, does not have one citywide net-metering policy. For homes in CoServ’s service area, new solar customers generally receive an export credit of about 6–8 cents per kWh for electricity sent to the grid, rather than a 1:1 credit at the retail rate. Solar power used in the home offsets electricity purchases.
CoServ’s solar buyback rate and applicable charges can change. Check your electric bill to confirm your provider and review its current export-credit terms; rules may differ elsewhere in McKinney.
Yes. A purchased and fully owned solar panel system may increase a McKinney home’s resale value. Zillow’s study found homes with solar panels sold for about 4.1% more on average, but that is not guaranteed; value depends on the home and local market.
This finding applies to owned systems, not leased or third-party-owned (TPO) panels. A lease may affect resale differently because the buyer may need to assume the agreement. Roof condition and system performance can also matter.
In McKinney, homeowners can go solar with a LightReach lease for a low fixed monthly payment and no upfront cost. The calculator above estimates $82–$153 per month based on home size; a typical 2,000–3,000-square-foot home is estimated at $114 per month.
A cash purchase is another option. The calculator estimates $18,797–$32,851, or $25,222 for a typical home. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. Actual pricing depends on your home and system.
A solar lease lets you use a system owned by Palmetto in exchange for a monthly payment, with no upfront cost. LightReach includes the panels, installation, monitoring, maintenance, and protection program with a 90% Production Guarantee.
For a typical 8.91 kW system in McKinney, the estimated payment is about $114 per month, based on Texas production of 1,339 kWh per kW annually and a rate of $0.115/kWh. Savings may start on day one if the payment is less than your current electricity bill; actual bills and savings vary.
McKinney homeowners may qualify for an Oncor solar incentive of up to $9,000 through an approved provider, subject to territory, project requirements, and funding. Texas also exempts qualifying solar equipment’s added appraised value from property tax. TXU and Gexa offer battery rewards to eligible customers under their program terms.
Texas has no statewide net-metering rate, so export credits depend on your retail electricity plan. The federal 30% residential tax credit is no longer available for cash purchases after the 2025 law change. For LightReach leases, Palmetto claims the commercial ITC and says it passes savings through as lower monthly payments.
Yes. Solar panels work well in McKinney’s sunny climate, which averages about 5.4 peak sun hours per day. Panels also produce electricity on cloudy days, though output is lower when clouds block sunlight.
Production changes with the seasons: longer summer days generally bring more output, while shorter winter days bring less. McKinney’s summer heat can also affect panel efficiency, so actual production varies with daylight, weather, and system conditions.
Solar panels in McKinney are low maintenance. They have no moving parts, and rain often washes away light dust. Check for visible damage after severe weather, such as hail, and have issues assessed by a qualified professional.
With a LightReach lease, Palmetto owns the system and handles monitoring, maintenance, and repairs at no extra cost. The lease also includes a 90% Production Guarantee.
