The cost of a solar panel system in Houston in 2025 is generally between $2 and $3 per watt. This means that a typical 10 kW solar panel system comprised of about 25 solar panels will cost between $20,000 and $30,000. After including local rebates and the 30% federal tax incentive, the net cost of a 10 kW system in Houston falls between $13,000 and $20,000. Several factors come into play when determining the final cost of a solar panel system in Houston including:
- The type of roof you have and the roof pitch
- The accessibility of your roof and equipment wall where electrical PV accessories need to be mounted
- The quality of solar panels, inverters and ancillary equipment used for the project
- Special local stipulations that add costs such as TDI Windstorm Certification requirements along the Gulf Coast
