FAQs
Is Tullahoma sunny enough for solar panels to be effective?
Yes. Tullahoma averages about 4.6–5 kWh of solar irradiance per square meter per day, similar to the U.S. Southeast overall. A well-oriented 6-kW residential array will typically generate 7,800–8,200 kWh per year—covering 70-100 % of an average home’s electricity use. Our design team uses local NOAA weather data and shading analysis to ensure every system is sized for optimum production.
What incentives or rebates are available for solar in Tullahoma and Tennessee?
Tennessee residents are eligible for the 30 % federal Investment Tax Credit (ITC) on the total installed cost. At the state level, solar equipment is exempt from sales tax, and Tennessee does not add property-tax value for the portion of your home that is solar-equipped. Through the Tennessee Valley Authority (TVA) Green Connect program, some Tullahoma Utilities Authority customers can receive a one-time $1,000 rebate when systems are installed by a TVA-approved contractor (we are certified). Local banks also offer low-interest Green Energy loans that can be paired with these incentives.
How does net metering work with Tullahoma Utilities Authority and TVA?
TVA operates a form of net billing. Your solar energy is first used by your home; excess production is exported to the grid and credited at TVA’s avoided-cost rate (currently about $0.03–$0.04 per kWh). You still buy power at the retail rate when the sun isn’t shining. Our monitoring portal tracks imports and exports so you can see monthly credits. We also design systems to maximize on-site consumption—often by timing water-heater or EV-charger loads—so you get the best financial return.
What does a typical solar installation cost in Tullahoma, and what is the payback period?
A turnkey 6-kW residential array runs about $15,500 before incentives. After applying the 30 % federal tax credit and the $1,000 TVA rebate, the net cost drops to roughly $9,850. With average utility rates of 11-12¢/kWh and 2-3 % annual escalation, most homeowners see annual savings of $900–$1,050. That translates to a simple payback of 9-11 years and an internal rate of return (IRR) of 8-10 %. Commercial projects generally pay back in 6-8 years because of accelerated depreciation and lower installed cost per watt.
How durable are the panels in Tennessee weather, and what maintenance is required?
Our Tier-1 panels are rated to withstand 1-inch hail at 50 mph and wind loads up to 140 mph—well above the strongest winds recorded in Tullahoma. The aluminum racking is corrosion-resistant and anchored to meet current International Building Code requirements. Maintenance is minimal: rinse the modules if heavy pollen reduces output, and schedule a system check every 3-5 years. We provide 25-year panel performance warranties, 10-year workmanship coverage, and free online monitoring so you can track performance daily.
Will my solar system power my home during an outage, and can I add batteries later?
A standard grid-tied solar array automatically shuts off when utility power is lost (for line-worker safety). If you want backup power, we can integrate a hybrid inverter and lithium-ion battery pack—either at install or as a future add-on. A 10-kWh battery will typically run critical loads (refrigerator, lights, internet, and a small heat pump) for 10–12 hours. During the day, the array recharges the battery so you can ride through multi-day outages. Our designs are modular, so we can expand storage capacity as your needs grow.
