Flower Mound consistently ranks among the highest-income communities in the DFW metroplex. The city's careful growth management has preserved a character of large wooded lots, well-designed planned communities, and homes that are predominantly newer and larger than the DFW average. That profile — high electricity bills, large south-facing roof planes, and homeowners who research carefully before committing — makes Flower Mound one of the strongest solar markets in Denton County.
Solar Costs in Flower Mound TX in 2026
Flower Mound homes are consistently larger than the DFW average, with many neighborhoods dominated by 2,800–4,500 sq ft two-stories built in the 2000s and 2010s. Most Flower Mound solar systems fall in the 10–15 kW range, reflecting both the larger homes and the higher summer AC loads that come with them.
| Home Size | Typical System | Installed Cost (Before Incentives) | Est. Annual Savings |
|---|---|---|---|
| 2,000–2,800 sq ft | 7–9 kW | $22,000 – $29,000 | $1,800 – $2,500 |
| 2,800–3,800 sq ft | 10–12 kW | $31,000 – $38,000 | $2,600 – $3,400 |
| 3,800–5,000 sq ft | 13–16 kW | $40,000 – $50,000 | $3,300 – $4,400 |
| 5,000+ sq ft | 16 kW+ | $50,000+ | $4,200+ |
Denton County Property Tax Exemption in Flower Mound
Flower Mound is in Denton County. The combined property tax rate — Denton County, Town of Flower Mound, and Lewisville ISD or Argyle ISD depending on your address — runs approximately 1.9–2.2%. Under Texas Tax Code §11.27, the full appraised value of your solar system is permanently exempt. On a $38,000 system at a 2.0% rate, that is $760 per year in avoided taxes — $19,000 over 25 years.
Flower Mound home values are high, and the assessed value that would otherwise be added to your tax bill by a solar installation is proportionally larger than in lower-value markets — which makes the exemption savings more significant here than in many other DFW cities. We file Form 50-123 with the Denton Central Appraisal District on every Flower Mound installation.
Solar and HOAs in Flower Mound
Flower Mound is extensively HOA-covered. Most of its planned communities have active Architectural Review Committees with defined processes for improvements including solar. Texas Property Code §202.010 protects your right to install regardless of what HOA documents say — no HOA rule prohibiting solar is enforceable under Texas law.
Flower Mound HOAs tend to be organized and responsive. They typically require rear or non-street-facing panel placement, flush mounting, and ARC pre-approval. We submit complete packages that address all of these requirements from the first submission — roof plans, panel specs, renderings on request, and installer license documentation. ARC review in Flower Mound communities typically takes 20–40 days.
Tree Coverage in Flower Mound
Flower Mound's wooded character is one of its defining features — and one of its solar nuances. Many Flower Mound lots have significant mature tree coverage that can shade portions of the roof. This is worth evaluating carefully before system design.
- ✓We conduct a full shading analysis using satellite data and on-site verification at every site visit
- ✓Partial shade on a string inverter system disproportionately reduces production from the entire string — Enphase microinverters solve this by making each panel independent
- ✓In heavily shaded yards, strategic pruning of a few key branches can meaningfully increase annual production
- ✓In some cases, shading reduces the viable system size significantly — we will tell you honestly if the economics are marginal for your specific lot
