Mansfield solar costs $2.05–$2.45/W in Oncor territory. A 10 kW system runs ~$22,500 gross. With a 2.35% property tax rate — one of the highest in DFW — the 100% Texas solar exemption saves $529/yr. Plus Oncor's $9,000 battery rebate and TXU retail-match buyback. No federal 25D tax credit.
2026 Alert: The federal residential solar tax credit (Section 25D) expired December 31, 2025. Mansfield homeowners who purchase solar with cash or a loan receive $0 in federal tax credits. All prices shown are full installed cost. Programs like Propel Solar use a third-party owner to access the commercial ITC with $0 down.
What a Mansfield homeowner actually pays in 2026. Mansfield's higher property tax rate (2.35%) means the 100% solar exemption saves you more than most DFW cities — turning a burden into an advantage.
Mansfield's 2.35% property tax rate is one of the highest in DFW. While that typically means higher tax bills, it actually works in your favor with solar. The 100% Texas property tax exemption means solar never increases your property taxes — and the higher the rate, the more you save compared to other cities.
Oncor's solar+battery rebate is the best utility solar incentive in any deregulated Texas territory. Here is how Mansfield homeowners can qualify.
A typical battery (Tesla Powerwall 3, 13.5 kWh) costs $12,000-$13,000 installed. With the $9,000 Oncor rebate, your net battery cost drops to approximately $3,500. In the Mansfield area, the primary battery value is backup power during grid outages (ERCOT reliability concerns after Winter Storm Uri). South DFW experienced rolling blackouts during both Uri (2021) and the June 2023 derecho. If backup power is important to you, the Oncor rebate makes the battery an excellent deal.
South DFW is in the same North Texas hail corridor as the rest of the metroplex. Mansfield homeowners should strongly consider impact-resistant panels to protect their investment.
| Panel | Hail Rating | Max Hail Size | Warranty |
|---|---|---|---|
| SunPower Maxeon 7 | IEC 61215 enhanced | 35mm (1.4 in) | 40 yr product + performance |
| REC Alpha Pure-RX | IEC 61215 enhanced | 35mm (1.4 in) | 25 yr product, 92% at yr 25 |
| Canadian Solar HiKu7 | Standard + enhanced testing | 25mm (1 in) standard | 25 yr product, 84.8% at yr 25 |
| Qcells Q.Peak DUO | IEC 61215 enhanced | 35mm (1.4 in) | 25 yr product, 86% at yr 25 |
Mansfield has the same excellent Oncor-territory REP options as Dallas. TXU Energy's retail-match plan is exclusively available in Oncor territory and gives you effective 1:1 net metering.

TXU Energy's Solar Buyback plan credits exported solar at the exact same rate you pay for consumption — effectively 1:1 net metering. This is the gold standard that most states mandate but Texas does not. If your TXU consumption rate is 15 cents per kWh, every kWh you export also earns 15 cents. The plan is only available in Oncor territory (DFW, Waco, Midland) — Houston and South Texas cannot access this plan. Mansfield residents are in Oncor territory and have full access.
Mansfield's 2.35% property tax rate turns into a significant advantage for solar owners. The higher the rate, the more the 100% Texas solar exemption saves you.
File Form 50-123 with the Tarrant Appraisal District (TAD) by April 30 following your solar installation. Mansfield straddles Tarrant and Johnson counties — check your property records to determine which appraisal district handles your address. Johnson County residents file with the Johnson County Appraisal District. The exemption prevents your property taxes from increasing due to the added value of your solar system. At 2.35% on a $22,500 system, this saves approximately $529 per year.

Estimates based on average 2026 TX solar pricing, 5.3 peak sun hours/day, 0.5%/year panel degradation, 3%/year electricity rate increase, and TX property tax exemption (Tax Code §11.27). Actual costs vary by installer, roof condition, and system configuration. Section 25D residential ITC expired Dec 31, 2025 — $0 federal tax credit for cash/loan purchases.
The calculator reflects $0 federal tax credit for cash and loan purchases. Section 25D expired December 31, 2025. Programs like Propel Solar use a third-party owner to claim the 30% commercial ITC (Section 48/48E) for projects beginning construction before July 4, 2026.
The Oncor solar+battery rebate of up to $9,000 is not automatically included in the calculator. If you plan to add battery storage, subtract the applicable rebate from the total system cost for a more accurate net cost estimate.
Propel Solar gives Mansfield homeowners $0 down solar with a fixed payment and full ownership by year 5 — no $22,500 upfront required.
A third-party financing company owns your system and captures the 30% Section 48 commercial ITC — savings that homeowners cannot access since 25D expired. That tax benefit funds your $0 upfront cost.
If your Mansfield electricity bill is $155/mo, your Propel payment is approximately $140/mo — saving roughly 10% from day one. The payment is fixed and predictable, unlike utility rates that increase 3-5% annually.
Full ownership transfers to you after approximately 5 years at no additional cost. Silfab 440W American-made panels with free maintenance during the financing period. You own the panels for the remaining 20+ years of their lifespan.
For Mansfield homeowners who do not have $22,500 in cash, Propel Solar provides immediate savings with zero upfront risk. Combined with Mansfield's high property tax exemption savings ($529/year), Propel plus the tax exemption delivers excellent value in south DFW.
