FAQs
How much sunlight does Greeneville receive, and what does that mean for solar energy production?
Greeneville averages 4.5–5.0 peak sun-hours per day across the year, which is excellent for solar. A properly oriented 1 kW array will generate roughly 1,350–1,500 kWh annually. For a typical 6 kW residential system, that translates to 8,000–9,000 kWh—often 75 % or more of a household’s yearly electricity demand. Because our designers optimize tilt and orientation for each roof, most homes can offset a significant portion of their utility bill without using additional ground space.
What incentives and rebates are available to Greeneville homeowners who go solar?
1. Federal Solar Investment Tax Credit (ITC) – 30 % off the entire installed cost through 2032. 2. TVA Green Connect/Green Power Providers – Qualifies systems for streamlined interconnection and may provide small performance-based payments. 3. Sales-tax exemption – Tennessee waives sales tax on most solar equipment. 4. Net billing with Greeneville Light & Power System (GLPS) – Excess power is credited on your bill at the avoided-cost rate, reducing long-term operating costs. 5. Accelerated depreciation for businesses – Commercial customers can claim MACRS plus the 30 % ITC, often resulting in a 5-year simple payback. Our team prepares all paperwork so you can capture every dollar you’re entitled to.
How much does a residential solar system cost in Greeneville, and what is the payback period?
Installed prices in our area run about $2.40–$3.00 per watt before incentives. A 6 kW system therefore costs $14,400–$18,000. After the 30 % ITC, the net cost drops to $10,080–$12,600. If your current electric bill is $140 per month, that system could cut it to roughly $35–$40, saving $1,200+ per year. Most homeowners see a simple payback of 8–12 years and an internal rate of return between 7 % and 12 %, all while increasing property value without raising property taxes.
What does the installation process look like and how long will it take?
1. Free site evaluation – We measure roof space, shading, and electrical service. 2. Proposal & design – You receive a detailed production estimate, layout, and financial analysis within 48 hours. 3. Permitting & utility approval – We handle building permits and the GLPS interconnection application. This step usually takes 2–4 weeks. 4. Installation – Most residential projects are completed in 1–2 days by our NABCEP-certified crew. 5. Inspection & commissioning – The city/county inspector and GLPS sign off, then we energize the system. Total timeline is typically 6–10 weeks from contract to power-on.
Will my solar panels work during a power outage?
Standard grid-tied systems automatically shut down when the grid goes dark to protect line workers. If you want backup power, you can add a battery (e.g., Tesla Powerwall, Enphase IQ Battery) and a hybrid inverter. During an outage, the battery and inverter form a safe local grid, allowing the panels to keep producing and the battery to power critical loads such as lights, refrigerators, medical devices, or even HVAC. We can size storage to match your exact backup requirements.
What maintenance do solar panels require, and how long will they last?
Solar PV systems are largely maintenance-free because they have no moving parts. We recommend: • Visual inspection and light cleaning with a garden hose once or twice a year to remove pollen or dust. • Annual online monitoring check (we include real-time monitoring with every system) to confirm expected production. • Inverter service or replacement after 12–15 years; most inverters carry a 10- or 12-year warranty extendable to 25 years. The panels themselves are warrantied for 25–30 years and typically still produce at least 80–85 % of their original output after that time. With minimal upkeep, you can expect decades of reliable, clean power.
