Sandy Allison, a partner with Alma Properties LLC, stands on the roof of 436 Market St. in Chattanooga. Allison is one of several people responsible for the instillation of solar panels on the roof of the building where The Johnson Group is located.• What: Workers finished installing a 50-kilowatt solar array on the roof of The Johnson Group, a public relations company. The 217 panels each produce 230 watts of power during peak hours, which is fed back into TVA’s grid.
• Companies: The Johnson Group, Tennessee Solar Solutions and Alamo Properties
• Location: The Johnson Group, 436 Market St.
• How it’s green: The panels feed power back into TVA’s grid during peak usage hours, saving an estimated $1,200 per month on the company’s electric bill, and helping to offset heavy demand for electricity in the region.
• Why do it this way? The wind doesn’t blow hard enough in Chattanooga to support a windmill, said Anthony Roden, president of Tennessee Solar Solutions. That leaves solar energy as the most efficient method of on-site power generation.
