Richardson solar costs $2.05–$2.45/W in Oncor territory. A 10 kW system runs ~$22,500 gross. Oncor offers up to $9,000 in solar+battery rebates. TXU retail-match gives you 1:1 net metering. Spanning Collin and Dallas counties with a 2.12% effective rate, Richardson's UTD campus area and established neighborhoods are strong solar markets. No federal 25D credit.
2026 Alert: The federal residential solar tax credit (Section 25D) expired December 31, 2025. Richardson 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 Richardson homeowner actually pays in 2026. Richardson's ~120,000 residents span two counties with established neighborhoods near UTD campus — from mid-century ranch homes to newer CityLine developments.
Oncor's solar+battery rebate is the best utility solar incentive in deregulated Texas. Here is how Richardson homeowners can qualify.
A typical battery (Tesla Powerwall 3, 13.5 kWh) costs $12,000-$13,000 installed. With the $9,000 Oncor rebate, your net battery cost drops to approximately $3,500. For Richardson homeowners — especially in the established neighborhoods with older grid infrastructure — battery backup provides critical protection during ERCOT stress events and summer outages. The mature tree canopy in some Richardson neighborhoods can cause localized power issues during storms.
Richardson is in DFW Hail Alley. Choosing impact-resistant panels is essential to protect your solar investment.

The 100% Texas property tax exemption is a major incentive. Richardson spans Collin and Dallas counties — your rate depends on your property location.
Richardson spans two counties: homes north of Renner Road are in Collin County (file with CCAD), while homes south are in Dallas County (file with DCAD). File Form 50-123 by April 30 following your installation. At an average 2.12% rate on a $22,500 system, this saves approximately $477 per year.
