Where can customers buy these systems? Is there a list of qualified vendors?
TVA does not recommend or require specific contractors and installers. However, we do recommend researching contractors to ensure quality work. System sizing tips, cost estimations, supplier/installer information, and related information can be researched at the following Websites: North American Board of Certified Energy Practitioners NABCEP is a volunteer board working to develop national voluntary standards and certifications for renewable energy professionals, beginning with solar electric installers. Look for the listings of these certified installers under the Resources link on the Web site.
