Texas solar homes come with a 100% property tax exemption and strong HOA protections — but the ERCOT deregulated market, REP buyback plan choices, and hail damage risk make Texas solar homebuying unlike any other state. This guide covers every TX-specific detail you need before closing.

Texas is the second-largest residential solar market in the United States, driven by abundant sunshine, rising electricity costs, and aggressive builder adoption. But the Texas solar landscape is fundamentally different from every other state because of ERCOT deregulation and extreme weather exposure.
Texas Property Tax Code Section 11.27 exempts the appraised value of solar and wind energy devices from property taxes — statewide, in every county. The solar system adds market value to the home without any increase to your annual tax bill.
Texas Property Code Section 202.010 prohibits HOAs from banning solar panels. An HOA may impose reasonable aesthetic restrictions, but cannot prevent installation or impose requirements that increase cost by more than 10% or reduce efficiency by more than 10%.
In deregulated ERCOT territory, you pick your own Retail Electric Provider (REP) and solar buyback plan — independent of the seller's choice. This gives you control over how much you earn for excess solar generation sent to the grid.
Texas has a lower lease/PPA penetration rate than California or New Jersey, but third-party-owned systems exist — especially Tesla Solar Subscriptions in the DFW and Austin markets.
Positive — $10,000-$18,000 premium
System ownership transfers with the deed. Buyer receives the 100% property tax exemption automatically under Section 11.27. No monthly payments, no credit check. In ERCOT deregulated areas, the buyer chooses their own REP and solar buyback plan independently of the system.
Buyer action: Verify system is free of UCC-1 liens. Request monitoring data and warranty documents.
Positive, reduced by payoff at closing
Outstanding loan balance must be paid off at closing from sale proceeds, per Texas home equity lending rules. The UCC-1 filing from the solar lender must be released. After payoff, the property tax exemption and all system benefits transfer cleanly.
Buyer action: Get a payoff letter. Confirm UCC-1 release at closing. Verify the loan is not a PACE lien (these attach to the property, not the borrower).
Neutral to slightly negative
Texas has a lower lease/PPA penetration than states like NJ and CA, but leased systems exist — particularly Tesla Solar Subscriptions and some Sunrun PPAs. The buyer must assume the remaining contract. Monthly payments, escalator clauses, and end-of-term obligations transfer to the new owner.
Buyer action: Request the full lease/PPA agreement. Review escalator rate, buyout schedule, remaining term. Compare projected year-25 payment to REP buyback rate.
In most of Texas, the electricity market is deregulated. This means the TDU (Transmission and Distribution Utility) manages the wires and interconnection, while you choose a competitive REP (Retail Electric Provider) for your electricity plan. For solar homeowners, the REP's solar buyback rate is critical:
| REP Buyback Type | Typical Rate | Best For |
|---|---|---|
| 1:1 Net Metering (Full Retail) | $0.10-$0.16/kWh | Highest value — excess solar offsets usage at full rate |
| Wholesale/Avoided Cost | $0.04-$0.08/kWh | Lower value — common with large REPs |
| Bill Credit (Fixed Rate) | $0.06-$0.12/kWh | Predictable — credits applied to future bills |
Key Advantage for TX Solar Homebuyers
You are NOT locked into the seller's REP. After closing, visit powertochoose.org, enter the property address, and compare solar buyback plans from all available REPs. This is a unique Texas advantage — in most states, you are stuck with whatever utility serves the property. In Texas, you shop for the best rate.
We will review the system specs, hail damage history, REP options, and estimated savings for any TX solar home.
Request Free EvaluationGood news for Texas buyers: no interconnection transfer is needed. The TDU interconnection follows the meter and property, not the individual homeowner. Here is what you need to know for each TDU:
DFW Metroplex, West Texas
No TDU transfer needed — interconnection follows the meter. New owner sets up service with their chosen REP.
Largest TX TDU. Oncor manages the interconnection and meter. The buyer picks any competitive REP for their buyback plan.
Greater Houston area
No TDU transfer needed. CenterPoint interconnection stays with the property. New owner selects a REP with solar buyback.
Houston hail zone — inspect panels carefully. CenterPoint manages distributed generation interconnection.
South and West Texas (Corpus Christi, Laredo, Midland)
No TDU transfer needed. Interconnection agreement stays with the property and meter.
Some AEP territory is outside ERCOT (co-ops, munis). Verify the property is in a deregulated area.
Scattered areas across TX
No TDU transfer needed. Smaller TDU with the same interconnection-follows-the-meter rule.
Fewer REP choices in some TNMP areas. Check available solar buyback plans before closing.
This is arguably the most important Texas-specific inspection. North Texas (DFW, Denton, Collin County) sits in Hail Alley, and Houston, San Antonio, and Austin also experience significant hail events. Hail damage to solar panels can be invisible to the naked eye but devastating to long-term performance.
What Is Electroluminescence (EL) Imaging?
EL imaging applies a reverse current through solar cells and photographs the resulting glow. Micro-cracks appear as dark lines or spots in the image. A panel can look physically perfect but have extensive internal cracking that reduces output by 10-30%. This test costs $200-$500 for a full system but is the only way to detect hidden hail damage. In DFW and Houston, consider this a non-negotiable part of your solar home inspection.
Tesla Electric (formerly Tesla Energy) operates as both a REP and a Virtual Power Plant (VPP) operator in Texas. If the home has a Tesla Powerwall, the seller may be enrolled in Tesla's VPP program, which discharges the battery during ERCOT grid peak demand events in exchange for bill credits.
Solar homes in Texas sell for approximately 3-4% more than comparable non-solar homes. The premium is lower than in Northeast states because Texas electricity rates are lower ($0.12-$0.16/kWh vs $0.18-$0.26/kWh in NJ). However, the 100% property tax exemption makes the premium pure upside with no annual tax increase.
| TX Metro | Median Home Price | Est. Solar Premium | Prop Tax Increase |
|---|---|---|---|
| Austin | $450,000 | $13,500-$18,000 | $0 |
| DFW (Dallas-Fort Worth) | $380,000 | $11,400-$15,200 | $0 |
| Houston | $320,000 | $9,600-$12,800 | $0 |
| San Antonio | $290,000 | $8,700-$11,600 | $0 |
Use this checklist before closing on any solar home in Texas:
Verify ownership: owned, loan, lease, or PPA
UCC-1 filing search at TX Secretary of State
Confirm 100% property tax exemption (Section 11.27) is applied on tax record
If HOA: verify solar installation complied with Property Code Section 202.010
Identify the TDU (Oncor, CenterPoint, AEP, TNMP) — no interconnection transfer needed
Research available REP solar buyback plans for the property address
Get 12-24 months of monitoring data (Enphase/SolarEdge/Tesla)
Hail damage inspection: visual + electroluminescence imaging
Check panel warranty (25-30 years) and inverter warranty (12-25 years)
Check for Tesla Electric VPP contract enrollment
Verify building permit and final inspection with municipality
Assess roof age — TX heat accelerates roof aging
No. Texas Property Tax Code Section 11.27 provides a 100% property tax exemption for solar and wind energy devices. The appraised value of the solar system is excluded from your property tax calculation. This is a statewide law — it applies in every county and municipality in Texas. The exemption is automatic for the property, but verify it is properly coded on the tax record.
No. Texas Property Code Section 202.010 prohibits HOAs from banning solar panels on residential property. An HOA can impose reasonable restrictions on placement (e.g., requiring panels on a rear-facing roof), but cannot prevent installation entirely or impose requirements that increase cost by more than 10% or reduce efficiency by more than 10%. As a buyer, check whether the existing installation complies with any HOA design guidelines — if it was already approved, you inherit that approval.
In most of Texas (deregulated ERCOT territory), you choose your own Retail Electric Provider (REP) — independent of the solar system. This means you are not locked into the seller's electricity plan. After closing, shop for a REP that offers the best solar buyback rate. Some REPs offer 1:1 net metering, others offer a lower buyback rate (typically $0.04-$0.10/kWh). Your choice of REP significantly affects the financial value of the solar system.
A REP (Retail Electric Provider) solar buyback plan determines how much you are paid for excess solar electricity sent to the grid. The seller's REP contract does NOT transfer to you — you select your own REP and buyback plan after closing. This is actually an advantage: you can shop for the best available buyback rate. Plans change frequently — compare rates at powertochoose.org and look for plans that credit excess generation at full retail rate.
Yes — this is arguably the most important Texas-specific inspection. North Texas (DFW, Denton, Collin County) is in Hail Alley, and Houston and San Antonio also experience significant hail events. Visual inspection alone is insufficient — micro-cracks from hail impact are invisible to the naked eye but reduce panel output over time. Request an electroluminescence (EL) imaging test from a certified solar technician. Also check the insurance claim history for hail-related claims on the system.
No. In ERCOT deregulated territory, the TDU (Transmission and Distribution Utility — Oncor, CenterPoint, AEP, or TNMP) manages the interconnection, and it follows the meter/property. When you set up service with your chosen REP, the distributed generation interconnection carries over. You do NOT need to re-apply for interconnection approval. However, in non-deregulated areas (co-ops, municipal utilities), check with the specific utility about their transfer process.
Tesla Electric (formerly Tesla Energy) operates a Virtual Power Plant (VPP) program in Texas where Powerwall battery owners can opt in to discharge their battery during grid peak demand events in exchange for bill credits. If the home has a Tesla Powerwall, check whether the system is enrolled in the Tesla Electric VPP program and understand the contract terms. VPP enrollment is voluntary and can typically be canceled, but review any commitment periods.
Solar homes in Texas sell for approximately 3-4% more than comparable non-solar homes. However, the premium is lower than in Northeast states because Texas electricity rates are lower ($0.12-$0.16/kWh vs $0.18-$0.26/kWh in NJ). On the TX median home price of ~$310,000, that translates to roughly $9,300-$12,400. The 100% property tax exemption makes this a pure value-add with no annual tax increase.
Key TX-specific red flags: (1) Hail damage — micro-cracks not visible to the naked eye, (2) No monitoring data or production history, (3) System installed without proper permit (common in rural areas), (4) Orphaned installation from a defunct company (Texas has had several solar company failures), (5) Property tax exemption not properly coded on the tax record (you could be overpaying taxes), (6) Roof needs replacement — TX heat ages roofs faster, and panel removal/reinstallation costs $3,000-$6,000, (7) System in a non-deregulated area (co-op or muni) with unfavorable net metering terms.
Yes. Texas Property Code Chapter 5 permits voluntary solar easements between property owners, but they are not automatic. A solar easement would protect the panels from shading by neighboring development. Check whether the seller recorded a solar easement with the deed. If no easement exists, neighboring construction or tree growth could shade the panels in the future without legal recourse — particularly relevant in rapidly developing Texas suburbs.
