Plano has emerged as one of the most active solar markets in the Dallas suburbs. The combination of large single-family homes built in the 1980s through 2000s, high household incomes tied to the Legacy Drive corporate corridor, and Collin County property tax rates that make the state exemption especially valuable creates strong fundamentals for solar. Here is what Plano homeowners need to know going into 2026.
Solar Costs in Plano TX in 2026
Plano solar installation costs run $18,000–$35,000 before incentives for a typical residential system. Plano's average home size is larger than many DFW suburbs — particularly in West Plano and the neighborhoods near Legacy and the Tollway — which often means systems in the 8–12 kW range rather than the smaller 6 kW systems more common in older, smaller suburbs.
| Home Area | Typical Plano Neighborhood | System Size | Est. Cost Before Incentives |
|---|---|---|---|
| 1,400–2,000 sq ft | East Plano, older subdivisions | 5–7 kW | $16,000 – $23,000 |
| 2,000–2,800 sq ft | Central Plano, 1990s builds | 7–9 kW | $23,000 – $28,000 |
| 2,800–3,800 sq ft | West Plano, newer sections | 9–12 kW | $28,000 – $36,000 |
| 3,800+ sq ft | Legacy area, newer construction | 12 kW+ | $36,000+ |
Collin County Property Tax Exemption: High Value in Plano
Plano sits in Collin County, which has a combined property tax rate (county + city + PISD) of approximately 2.0–2.4%. That rate, applied to the full value of your solar system under Texas Tax Code §11.27, generates meaningful annual savings. On a $28,000 system, a 2.2% rate exemption saves $616 per year — $15,400 over a 25-year system life.
Plano homeowners have an additional reason the exemption is valuable: Plano home values are high, meaning the appraised value of a solar system may be assessed at a higher dollar figure than in lower-value markets. A larger assessed value that is exempt from taxation is proportionally more valuable. We file Form 50-123 with the Collin Central Appraisal District (CCAD) on every residential Plano installation.
Plano's Housing Stock and Solar Compatibility
Most Plano homes were built between 1980 and 2005. For solar, this vintage is ideal: roofs are large enough for meaningful systems, home orientation in planned subdivisions is generally favorable, and roof conditions are usually serviceable. A few Plano-specific factors:
- ✓Brick and frame construction: Standard for Plano. No effect on solar installation.
- ✓Composition shingle roofs from the 1990s: Many Plano homes are approaching roof replacement age. Combining a new roof with solar installation saves $2,000–$4,000 versus doing them separately — we coordinate with roofing contractors.
- ✓HOA communities: Plano has numerous HOA neighborhoods, particularly in West Plano. Texas law (§202.010) protects your right to install solar regardless of HOA rules. We handle all ARC submissions.
- ✓Two-story homes in West Plano: Larger roof area and typically larger electricity usage — solar ROI is strong.
- ✓Mature trees near the roofline: East Plano's older neighborhoods can have significant tree shade. We use shading analysis tools and, where needed, recommend microinverters to minimize impact.
Oncor Service in Plano and Solar Buyback Options
All of Plano is served by Oncor Electric Delivery. As an Oncor customer, you have access to the Oncor Solar+Storage rebate (up to $9,000 for battery installations) and to the competitive retail electric market where solar buyback plans from providers like Rhythm Energy, Green Mountain Energy, TXU, and Reliant can earn you bill credits for excess power your system produces.
Plano electricity bills average $180–$320 per month for mid-size homes, spiking to $350–$500+ in summer. A properly sized solar system covers 85–100% of annual usage, with spring and fall surpluses building credits against summer deficits. Net annual savings for a typical Plano installation run $1,800–$3,000 depending on system size and REP plan.
Permitting Solar in Plano
The City of Plano Development Services Department handles residential solar permits. Plano has a well-established solar permit process — the city has processed hundreds of residential solar applications and the typical permit timeline is 5–15 business days. We handle the complete permitting process including drawing submission, permit fees, and coordination with city inspectors.
What Plano Solar Customers Ask Us Most
- ✓"My roof is 20 years old — do I need to replace it first?" We assess every roof during the free site visit. If replacement is coming within 5 years, coordinating now saves money. If the roof has 10+ years left, installing solar first is fine.
- ✓"Will my HOA approve it?" In every Plano HOA where we have applied, the answer has been yes. Texas law protects your right to install, and our ARC package is designed to address the most common HOA concerns.
- ✓"My neighbor's system doesn't seem to produce much." Undersized or poorly sited systems are common in Plano because national installers use national average sizing. We size specifically to your actual electricity usage.
- ✓"What happens when I sell?" Owned solar adds resale value. Lawrence Berkeley National Laboratory found a $3–$4 per watt premium in Texas markets. On a 10 kW system, that is $30,000–$40,000 in added home value.
