Keller occupies the affluent corridor between Fort Worth and Southlake in northern Tarrant County, with a housing stock dominated by well-built homes from the 1990s through the 2010s and a community that has consistently prioritized property values, quality schools, and careful development. Homeowners here tend to be deliberate buyers — the same profile that makes a thorough solar evaluation worthwhile. Here is what Keller homeowners need to know in 2026.
Solar Costs in Keller TX in 2026
Keller homes are consistently larger and newer than the DFW average — most residential systems fall in the 10–15 kW range, reflecting the city's larger average home size and higher electricity consumption relative to older, smaller DFW suburbs.
| Home Size | Typical System | Installed Cost (Before Incentives) | Est. Annual Savings |
|---|---|---|---|
| 2,200–3,000 sq ft | 8–10 kW | $25,000 – $32,000 | $2,000 – $2,800 |
| 3,000–4,000 sq ft | 10–13 kW | $31,000 – $40,000 | $2,600 – $3,600 |
| 4,000–5,000 sq ft | 13–16 kW | $40,000 – $50,000 | $3,400 – $4,500 |
| 5,000+ sq ft | 16 kW+ | $50,000+ | $4,200+ |
Tarrant County Property Tax Savings in Keller
Keller is in Tarrant County. The combined property tax rate — Tarrant County, City of Keller, and Keller ISD — runs approximately 2.1–2.4%. Under Texas Tax Code §11.27, the full appraised value of your solar system is permanently exempt from that rate. Keller home values are high, meaning the assessed value exempted is proportionally larger than in lower-value markets.
On a $38,000 system at a 2.2% combined rate, that is $836 per year in avoided property taxes — $20,900 over 25 years. Combined with $2,500–$3,500 in annual electricity savings, the long-term financial case for solar in Keller is among the strongest in Tarrant County.

Keller's Housing Stock and Solar Compatibility
Keller's homes are predominantly from the 1990s and 2000s — newer enough to have modern electrical infrastructure, old enough that some roofs may be approaching the 20–25 year replacement window. Key factors for Keller homeowners:
- ✓Roof vintage: 1990s and early-2000s composition shingle roofs in Keller may have 5–15 years remaining. We assess roof condition during every free site visit — if replacement is near, combining it with solar saves $2,000–$4,000.
- ✓Premium panel aesthetics: Keller homeowners frequently choose all-black panels (black cells, frame, and backsheet) for a cleaner look on high-visibility roof sections. This is our default recommendation for HOA communities.
- ✓Enphase vs. string inverter: Large multi-section Keller rooflines benefit from Enphase microinverters, which allow each panel to operate independently. Particularly useful in homes with east-west and south-facing sections that produce at different times of day.
- ✓Tree coverage: Keller's newer planned communities have less mature tree cover than older DFW suburbs, which generally means lower shade impact and higher annual production per panel.
