Rowlett occupies a peninsula-like position on the western shore of Lake Ray Hubbard in eastern Dallas County. The city grew rapidly from a small community in the 1980s into a suburb of around 70,000 residents with a housing stock dominated by homes built from the 1990s through the 2010s. Newer construction, open lots, minimal shade, and consistent sun exposure make Rowlett a strong solar market. Here is what Rowlett homeowners need to know in 2026.

Why Rowlett Is Particularly Well-Suited for Solar
- ✓Newer housing stock (1990s–2010s): most roofs have significant life remaining and modern electrical infrastructure — minimal pre-installation upgrades needed
- ✓Open lot layouts: Rowlett's master-planned communities have wide lot spacing and minimal mature tree coverage, which means less shading and higher annual production per panel
- ✓Waterfront exposure: lake-adjacent neighborhoods receive excellent sun exposure without the shade issues common in older, more densely treed Dallas neighborhoods
- ✓Strong Oncor service throughout: all of Rowlett is served by Oncor, giving full access to the Solar+Storage rebate and ERCOT retail competition
Rowlett After Winter Storm Uri: Battery Storage Interest
The 2021 winter storm that knocked out power across DFW hit Rowlett particularly hard given the city's exposure as a peninsula. Interest in battery backup from Rowlett homeowners has been consistently high since then. The Oncor Solar+Storage rebate of up to $9,000 makes pairing a Tesla Powerwall or Enphase IQ battery with solar much more financially accessible.
