Mascot Pecan Shelling Co. in Glennville recently had Coastal Solar, based in Hinesville, install a solar array system, an investment of more than $2.5 million that is projected to pay for itself in power savings and incentives in four to seven years.Mascot Pecan hired the solar installation company that specializes in agricultural projects to erect 3,400 solar panels, each rated 320 watts, on six acres adjacent to the processing plant. For the shelling company, the energy required to shell, cool and freeze its pecans was increasing each year, topping out at more than 2.2 million kilowatt hours and a $260,000 power bill last year, according to a news release from Coastal Solar. Federal solar tax incentives should help Mascot recover its initial investment within seven years, and if the company’s owners, brothers Kenny and Tim Tarver, are awarded a Rural Energy for America Program, or REAP, grant they have applied for from the U.S. Department of Agricultural, the investment recovery time will shrink to less than four years, the installation company announced.
