Wylie sits at the eastern edge of Collin County, bordered by Sachse, Garland, Rowlett, and Lake Lavon. It has transformed dramatically over the past two decades from a small agricultural community into one of the faster-growing mid-size cities in North Texas, with a housing stock dominated by 2000s–2020s construction. New homes, larger lot sizes, and strong median household incomes make Wylie one of the better solar markets in the DFW northeastern corridor.
Solar Costs in Wylie TX in 2026
Wylie homes tend to be newer and often larger than the DFW average — many neighborhoods feature homes in the 2,000–3,500 sq ft range on quarter-acre or larger lots. Most residential solar systems here fall between 9 kW and 14 kW, reflecting above-average home sizes and the cooling loads that come with Texas summers.
| Home Size | Typical System | Installed Cost (Before Incentives) | Est. Annual Savings |
|---|---|---|---|
| 1,800–2,500 sq ft | 8–10 kW | $25,000 – $32,000 | $2,100 – $2,900 |
| 2,500–3,200 sq ft | 10–13 kW | $32,000 – $41,000 | $2,700 – $3,700 |
| 3,200–4,200 sq ft | 13–16 kW | $40,000 – $50,000 | $3,400 – $4,500 |
| 4,200+ sq ft | 16 kW+ | $50,000+ | $4,200+ |
Collin County Property Tax Savings in Wylie
Most of Wylie is in Collin County (with a small portion in Rockwall County). The combined property tax rate — Collin County, City of Wylie, and Wylie ISD — typically runs 1.9–2.3%. The Texas solar property tax exemption removes the full appraised value of your solar system from your taxable property value permanently.
On a $35,000 system at a 2.1% rate, that is $735 per year in avoided property taxes — over $18,000 over a 25-year system life. Zencore Solar files Form 50-123 with the Collin Central Appraisal District (CCAD) after installation.
