Since last summer, the Tennessee Solar Institute has awarded $9 million in grants to 112 projects totaling $33 million worth of solar energy capacity. One of these projects took place at the Commerce Union Bank’s East Main branch in Gallatin.
Â
Ron Deberry, owner of Commerce Union Bank, has always had an interest in sustainability. Several years ago he put this interest to action as he researched the qualifications necessary to make the Gallatin Commerce Bank at 1204 Nashville Pike the first LEED certified building in Sumner County. But the bank’s East Main branch was a 30-year-old building, and Deberry knew the building would not be able to become LEED certified.
Â
However, about a year ago, Deberry had a conversation with a customer who owns a shopping center located in the neighboring town of Hendersonville, where he had just installed solar. Deberry then decided to further investigate solar energy as a way to power the East Main branch.
Â
He started with a phone call to Steve Johnson, president of LightWave Solar. LightWave Solar then met with Deberry for a consultation to survey the site and create a plan for a solar system install.
Â
LightWave Solar helped Deberry apply for the Solar Installation Grant, and upon completion of the project, Commerce Union Bank received $38,480 for the bank’s 20,000-watt array consisting of 84 solar panels and three inverters.
Â
“LightWave took care of the entire grant application process,” Deberry said. “They created a firm timeline for the grant application and stuck to it. They completed the paperwork to the point that all I had to do was read it, sign it and turn it in.”
Â
In addition to the grant, LightWave Solar presented a package of all the incentives that the bank was eligible for including the 30% Federal Treasury Grant; TVA’s Generation Partners program rebate of $1,000; and 100% Bonus Depreciation.
Â
The bank is able to sell solar electricity (about 22,700 kilowatt-hours of it in an average weather year) to the Tennessee Valley Authority. TVA pays the bank about twice what the bank pays Gallatin Department of Electricity for conventional electricity. The income will be approximately $5,000 per year, which will be enough to pay off the net cost of the system in about 6 years.
Â
“The project yielded a very attractive return on investment,” said Deberry. “It also shows our commitment to environmental conservation.”
Â
LightWave Solar reports that in just one year, Commerce Union Bank’s system will generate 22,727 kWh, offsetting 61,360 pounds of carbon dioxide (the leading greenhouse gas), 160 pounds of nitrous oxide (causes smog) and 320 pounds of sulfur dioxide (cause of acid rain). Within the system’s 25 year warranty, these annual offsets add up to the equivalent to taking 100 cars off the road or planting 150 acres of trees.
