Licensing (PV)
A state electrical contractor license is required for any company in the business of installing, erecting, repairing or altering electrical systems, or apparatus used for electrical light, heat, power or signaling. Person(s) performing the PV electrical installation for the electrical contractor must be a licensed electrician. The Texas Electrical Safety and Licensing Act allows for municipal and regional regulation.

Licensing (Solar thermal)
A license is required to install and make connections to the potable water system. Each plumbing company must have a responsible master plumber that over sees all work. However, the responsible Mmaster may delegate tasks to others. Typically these installations would be done by a Journeyman Plumber. All work is subject to permit and inspection by the local code authority. All plumbing in Texas is licensed and regulated by the Texas State Board of Plumbing Examiners.
