4.1% Higher sale price: Homes with solar sell for 4.1% more than comparable homes without solar. On a $330,000 TX home, that is approximately $13,500.
20 days Faster sale: Solar homes in Texas sell approximately 20 days faster than non-solar homes, as buyers value lower electricity bills in a high-usage state.
97% Cost recovery at sale: Homeowners recover about 97% of their solar investment when they sell. Owned (not leased) systems perform best.
79% Buyers willing to pay more: 79% of homebuyers say solar panels are a desirable feature. In Texas, high electricity bills make solar an even stronger selling point.
Texas has the second-highest property taxes in the US. The 100% solar exemption turns this disadvantage into a major benefit.
Your county appraisal district assesses your home’s value annually. When you add solar panels worth $20,000, your home’s appraised value normally increases by $20,000.
Without the exemption: $20,000 × 2.2% tax rate = $440/year in new taxes.
With the exemption: The $20,000 solar value is excluded from taxation = $0/year in new taxes.
Does not account for property tax rate increases, which would make the exemption even more valuable over time.
Based on a $20,000 solar system. Higher-tax counties save more because the exemption shields a larger annual tax burden.

Bottom line: The property tax exemption is Texas’s single most valuable solar financial benefit beyond direct energy savings. No federal ITC, no state credit, no state income tax deduction. The property tax exemption and energy savings are the complete financial picture for TX solar homeowners in 2026.
Owned solar systems add the most value. Leased systems require the buyer to take over the lease, which complicates the sale and may deter some buyers. If you finance, pay off the loan before selling if possible.
Buyers and their agents will verify the exemption is in place. A solar system with the exemption filed is more attractive than one without it. File Form 50-123 immediately after installation.
Keep 12-24 months of electricity bills showing solar savings. Provide before-and-after comparisons. Buyers respond to concrete dollar savings, not theoretical projections.
Show your solar buyback plan and export credits. A buyer who sees real monthly credits from TXU or Green Mountain understands the ongoing value immediately.
Solar adds $15,000–$25,000 to your Texas home value — exempt from property taxes under Section 11.27. But you don't need to pay $22,000+ upfront to get there. NuWatt's Propel financing installs FEOC-compliant Silfab panels with a third-party owner claiming the 40% Section 48E ITC. You pay ~$117/month for an 8 kW system (at $2.90/W), $0 down, 8.99% APR, 25-year term, 660 FICO. Ownership transfers after year 5, triggering the property tax exemption for you.
