FAQs
How much can I expect to save on my electric bill in Sale Creek by going solar?
The average Sale Creek home uses roughly 1,100–1,300 kWh of electricity per month at a retail rate of about 11¢ / kWh. A properly sized 6–8 kW rooftop solar array can offset 75–100 % of that usage, trimming $95–$140 from your monthly bill. Over the 30-year life of the system, that translates into $35,000–$50,000 in avoided utility charges—even after accounting for modest maintenance and inverter replacement costs.
What incentives and tax credits are available for solar installations in Tennessee and the Sale Creek area?
• Federal Solar Investment Tax Credit (ITC) – 30 % of your total project cost can be claimed as a dollar-for-dollar reduction on your federal income taxes. • Tennessee sales-tax exemption – Solar equipment is exempt from the state’s 7 % sales tax, automatically lowering your upfront cost. • Local property-tax relief – Hamilton County currently excludes the added value of a solar array from property-tax assessments. • TVA/Local Power Company programs – TVA’s Green Connect and Dispersed Power Production agreements provide a simple path to interconnection and may pay a small premium (1–2 ¢ / kWh) for exported energy on 20-year contracts. These incentives can reduce net project cost by 35–40 % and shorten payback time by several years.
How does net metering or energy buy-back work with TVA and EPB/Volunteer Energy in Sale Creek?
Tennessee Valley Authority (TVA) does not offer true retail net metering; instead, homeowners sign a Dispersed Power Production (DPP) agreement through their local power company (EPB, Volunteer Energy, etc.). • All the solar power you generate is first used in the home, offsetting consumption at the full retail rate. • Excess production is exported to the grid and credited at TVA’s avoided-cost rate (about 2.5–3 ¢ / kWh) or, if you enroll in Green Connect, at avoided cost plus a 1.5 ¢ premium. • Credits appear on your bill each month and roll forward for one year but cannot exceed your annual usage. Because the export credit is lower than the retail rate, we design your system to minimize excess generation and maximize on-site consumption. Adding a battery can further increase self-consumption and provide backup power during outages.
What is the average cost and payback period for a residential solar system in Sale Creek?
Installed prices in southeast Tennessee currently run $2.60–$3.10 per watt before incentives. A typical 7 kW system therefore costs $18,200–$21,700 upfront. After applying the 30 % federal ITC, the net cost falls to $12,740–$15,190. At today’s electric rates, annual bill savings of $1,150–$1,350 produce an 9–13-year simple payback. With modest utility-rate inflation (3 %/yr), the project’s internal rate of return (IRR) is typically 8–11 %, outperforming many conservative investments while locking in decades of predictable energy costs.
Will my solar array still produce enough energy during Sale Creek’s winters and cloudy days?
Sale Creek receives about 4.5 peak sun-hours per day on a yearly average—well above the national median. Winter months average 3.2 sun-hours, while summer months see 5.4 +. Your system will make less power on short, overcast winter days, but spring and summer over-production largely offsets those seasonal dips. When sized correctly and paired with TVA credit rollover (or on-site battery storage), annual production will cover the percentage of usage we target in your design, keeping your yearly savings on track.
What permits and inspections are required for a solar installation in Sale Creek, and do you handle them?
Yes. Our team manages the entire permitting and interconnection process for you: 1. Engineering review and stamped structural drawings. 2. Electrical and building permits from Hamilton County Building Inspection Services. 3. Interconnection approval from your local power company (EPB/Volunteer Energy) and TVA, including single-line diagrams, load calculations, and liability insurance certificates. 4. On-site inspections during construction and a final walkthrough with the county inspector. 5. TVA commissioning test and issuance of the DPP/Green Connect agreement. Because we handle the paperwork and schedule all inspections, you simply sign a few forms and wait for permission to operate (PTO), typically 4–8 weeks from contract signing.
