Garland solar costs $2.05–$2.45/W in Oncor territory. A 10 kW system runs ~$22,500 gross. With a housing stock heavy in 1970s-2000s homes with large, solar-friendly roofs, Garland is ideal for solar. Oncor offers up to $9,000 in battery rebates. No federal 25D tax credit.
2026 Alert: The federal residential solar tax credit (Section 25D) expired December 31, 2025. Garland homeowners who purchase solar with cash or a loan receive $0 in federal tax credits. All prices shown are full installed cost. Programs like Propel Solar use a third-party owner to access the commercial ITC with $0 down.
What a Garland homeowner actually pays in 2026 — with and without the Oncor solar+battery rebate.
Most Garland residential customers are in Oncor delivery territory, qualifying for the best utility solar incentive in deregulated Texas. Note: Some areas served by Garland Power & Light (GP&L) may not qualify.
Some Garland residents are served by Garland Power & Light (GP&L), a municipal utility that is NOT part of Oncor or the deregulated ERCOT market. GP&L customers do not have access to the Oncor solar+battery rebate or TXU retail-match buyback. Check your utility bill to confirm which utility serves your address. If you are a GP&L customer, solar is still viable but the economics differ — GP&L offers its own interconnection program with different buyback rates. Most newer Garland subdivisions are in Oncor territory.
Garland's northeast DFW location puts it in the direct path of many supercell storms. Hail-resistant panels are strongly recommended.
