Hiring/Contracting Questions

  • What, if any, certifications or licenses are required by contractors? Licensing requirements are put into place to protect consumers as well as the reputation of the industry. Contractor licensing is required by and specified by states. Certifications are optional for installers/contractors. It reflects additional training, experience, or testing voluntarily undertaken by the installer/contractor.
  • How do I find a qualified contractor? There are websites that can help you find a qualified contractor. For solar, visit the Nabcep website. For geothermal, visit the Oklahoma University website. Currently, there are no national databases for wind energy contractors. You may want to contact wind turbine manufacturers to find possible distributors in your area. For information on wind energy, visit the American Clean Power website.
