FAQs
Does Tullahoma get enough sunshine for solar power to make sense?
Absolutely. Tullahoma averages about 4.6–4.8 kWh of solar irradiance (sunlight) per square meter per day—very close to the U.S. national average. That level of sunshine allows a properly sized 5-kW residential array to generate roughly 6,200–6,400 kWh of electricity per year, offsetting 50–90 % of a typical household’s annual usage. A brief roof assessment (azimuth, pitch, shading) will confirm whether your property can take full advantage of the available sunlight.
What incentives or rebates can I claim on a solar installation in Tullahoma?
Homeowners can take advantage of the 30 % Federal Investment Tax Credit (ITC) through 2032. Tennessee does not levy a state income tax, so there’s no state-level tax credit, but your system is exempt from state and local sales tax under T.C.A. § 67-6-346. Depending on your electric utility—most Tullahoma residents are served by Duck River Electric Membership Corporation (DREMC) or Tullahoma Utilities Authority (TUA)—you may also be able to enroll in a performance-based or net-billing program that credits you for excess power fed back to the grid.
How does grid interconnection and net metering work with DREMC or TUA?
Both DREMC and TUA follow TVA’s "Dispersed Power Production" guidelines. Instead of classic 1-for-1 net metering, you’ll enter a net-billing agreement in which energy exported to the grid is credited at a slightly lower avoided-cost rate and energy you draw is billed at the retail rate. We handle the interconnection application, compliance with IEEE 1547 and UL 1741, and the installation of the required production meter. The process typically takes 2–4 weeks for approval and another 1–2 weeks for the final utility inspection and meter swap.
How much will a residential solar system cost and what is the payback period in Tullahoma?
Installed costs in middle Tennessee currently run about $2.40–$2.70 per watt before incentives. A 7-kW system therefore costs roughly $16,800–$18,900. After applying the 30 % ITC, the net cost drops to about $11,800–$13,200. With average utility rates of 12–13 ¢/kWh and annual bill savings of $900–$1,050, the simple payback is typically 11–13 years, while the equipment is warrantied for 25–30 years. Factoring in projected utility rate increases, many customers reach breakeven even sooner.
What permits and inspections are required, and do you handle them for me?
Yes. We submit a building/electrical permit application to the City of Tullahoma Building Codes Department or the appropriate Coffee/Franklin County office, complete any TVA interconnection forms, schedule all utility and code inspections, and provide a stamped structural letter when needed. Permitting usually takes 5–10 business days, and our team coordinates every step so you never have to visit city hall or deal with paperwork.
What maintenance and warranty coverage can I expect from your solar installations?
Solar installations are low-maintenance—no moving parts and self-cleaning tempered-glass modules. We include a 25-year power-output warranty on Tier-1 panels, 12–25 years on micro-inverters or string inverters (extendable), and a 10-year workmanship warranty on our labor, roof penetrations, and electrical work. Annual maintenance is limited to an optional visual inspection and panel wash, but we offer a monitoring portal that instantly alerts us to any fault so we can dispatch a technician if performance drops.
