Houston is one of the most promising solar markets in the United States. With over 200 sunny days per year, high average electricity rates (around 12–14 cents per kWh), and a growing population that exceeds 2.3 million in the city proper and 7 million in the metro area, demand for residential and commercial solar has surged. Texas leads the nation in utility-scale solar, but rooftop installations are catching up quickly thanks to federal Investment Tax Credits (ITC), local property tax exemptions for solar systems, and net metering policies offered by CenterPoint Energy, the dominant utility in the Houston area.
The market is competitive but still underserved in many suburban neighborhoods such as Katy, Sugar Land, The Woodlands, and Pearland. Homeowners in newer subdivisions are increasingly asking for solar as a standard upgrade, while older homes in central Houston (Heights, Montrose, Bellaire) are retrofitting to lower high summer cooling bills. Commercial properties, including warehouses and office parks, also present a strong opportunity. The key drivers are energy independence, tax incentives, and rising environmental awareness among Houston's diverse population.
However, the market is not without challenges. Extreme weather events (hurricanes, hail, heatwaves) require installers to design robust, code‑compliant systems. Competition from national players like Sunrun and Tesla is growing, but local companies can win by offering personalized service, faster installation times, and deep knowledge of local permitting and incentive programs.
As of January 1, 2024, Texas requires all solar installation companies to be licensed by the Texas Department of Licensing and Regulation (TDLR) under the Solar Energy System Installation program. You must hold a Class A or Class B license depending on the scope of work. Class A allows installations on any building; Class B is limited to residential structures under 10,000 square feet. Additionally, any employee performing electrical work must hold a valid Texas electrical license (Apprentice, Journeyman, or Master Electrician). For solar‑only work that does not involve connecting to the building’s main panel, a Residential Appliance Installer (RAI) license may suffice — but most full‑system installations require a properly licensed electrician.
Every solar installation requires a building permit from the City of Houston’s Permit Center, plus an electrical permit. You must submit structural calculations, panel layout, electrical single‑line diagrams, and interconnection agreements. The city has a dedicated solar permitting process, but plan review can take 2–4 weeks. Consider hiring a permit expeditor familiar with Houston’s requirements to avoid delays.
You need general liability insurance (minimum $1 million per occurrence), workers’ compensation coverage if you have employees, and a Texas registered agent. Register your business with the Texas Secretary of State (LLC or corporation recommended) and obtain a Sales and Use Tax Permit from the Texas Comptroller. Also register with the Texas Workforce Commission for unemployment insurance.
CenterPoint Energy requires a signed interconnection agreement before the system can be turned on. You must use an approved inverter and meter, and the system must pass a final inspection by the city and a meter swap arranged by CenterPoint. Net metering credits are at the retail rate but subject to annual true‑ups. Stay updated on ERCOT rules, as changes can affect payback periods.
