FAQs
Does Greeneville get enough sunshine for solar panels to be worthwhile?
Yes. Greeneville averages roughly 4.5–5 peak sun-hours per day over the year, which is only slightly lower than the national average for good solar locations (5–5.5). A 6-kW array on a south-facing roof can typically generate 8,000–9,000 kWh of electricity annually—covering 80–100 % of a typical Greeneville home’s electric use.
What incentives or rebates are available for solar installations in Greeneville?
1. Federal Investment Tax Credit (ITC) – 30 % of the total system cost (equipment, labor, permitting) can be claimed as a credit on your federal taxes through 2032. 2. Sales-tax exemption – Solar equipment is exempt from Tennessee state sales tax. 3. Property-tax exemption – The added value of a solar system is not included in county property-tax assessments. 4. TVA & Greeneville Light & Power programs – TVA’s "Green Connect" provides a $500 rebate for qualifying systems and streamlined interconnection. Additional limited-time buy-back programs may be offered; ask us for the latest enrollment details. 5. USDA REAP grant – Rural small businesses and agricultural producers may qualify for a grant covering up to 50 % of project costs.
How does net metering work with Greeneville Light & Power and TVA?
Tennessee does not mandate traditional 1-for-1 net metering. Instead, you consume your solar power in real time and any surplus is sent to the grid. Greeneville Light & Power (serving TVA) will credit excess generation at TVA’s avoided-cost (wholesale) rate—typically 2–4 ¢/kWh—on your monthly bill. Credits roll forward month-to-month for one year. Because the credit rate is lower than what you pay for electricity, sizing the system to maximize on-site consumption gives the best return. Our designers help optimize array size and orientation for your usage profile.
What does a residential solar system cost in Greeneville and how long is the payback?
As of 2024, turnkey pricing in our area averages $2.40–$2.80 per watt before incentives. A typical 6-kW home system therefore costs $14,400–$16,800. After the 30 % ITC, net out-of-pocket falls to about $10,000–$11,700. With current residential electricity rates around 12–13 ¢/kWh and yearly production of ~8,500 kWh, the system saves $1,000–$1,100 per year. Simple payback is 9–12 years, while panels are warranted for 25 years and often produce for 30+. That delivers an internal rate of return of 8–10 %—higher if utility rates rise.
How long does the solar installation process take and what permits are required?
1. Site assessment & proposal: 1–2 weeks. 2. Engineering & utility interconnection application: 2–3 weeks. 3. Municipal building permit (City of Greeneville or Greene County): 1–2 weeks. 4. Installation: 1–2 days for most residential roofs. 5. Inspection & meter swap by Greeneville Light & Power: 1–2 weeks. Overall timeline: 4–8 weeks from signed contract to system turn-on. We handle all drawings, structural calculations, building permits, and the TVA/GL&P interconnection paperwork so you only sign a few forms.
How will my solar panels perform during Greeneville’s winters, cloudy days, and occasional snow?
Solar panels still generate electricity under diffuse light. On overcast days they produce 10–30 % of their rated power; energy generation is spread across the year, with about 65–70 % occurring March–September and 30–35 % October–February. Light snow generally slides off within 24–48 hours because panels warm in the sun; heavy snow events are rare and annual losses from snowfall are <2 %. We use high-efficiency monocrystalline modules with low-temperature coefficients so they actually perform better on cool, sunny winter days than in midsummer heat.
