FAQs
What are the key benefits of installing solar panels in Jonesborough?
Solar panels lower your monthly electric bills, protect you from rising utility rates, and increase your home’s value. Jonesborough receives ample sunshine—about 4.5–5 peak sun-hours per day on average—so systems generate solid year-round power. In addition, Tennessee exempts solar equipment from state sales tax and offers a property-tax exemption on the added value, giving Jonesborough homeowners an even faster payback.
Is there enough sunlight in Jonesborough for solar to be worthwhile?
Yes. Washington County averages roughly 210 sunny or partly sunny days each year. When those days are converted to solar peak-hour equivalents, most homes can expect 1,300–1,500 kWh of production per installed kW annually. A typical 7-kW residential array therefore produces 9,000–10,500 kWh per year, offsetting 80–100 % of an average household’s electricity use.
What incentives, rebates, or financing options are available locally?
1. Federal Solar Investment Tax Credit (ITC): 30 % of the entire system cost can be claimed on your federal income taxes. 2. TVA Green Connect Program: Qualifying systems in the Tennessee Valley Authority region may earn performance-based credits for the power they export. 3. State Sales-Tax Exemption: Solar equipment is exempt from Tennessee’s 7 % sales tax, lowering upfront cost. 4. Property-Tax Exemption: Added property value from solar is not included when the county assessor calculates your tax bill. 5. Low-interest loans: Local lenders such as Appalachian Community Federal Credit Union offer green-energy loans with terms up to 15 years. Our team will help you stack these incentives and find the best financing plan.
How long does the entire solar installation process take in Jonesborough?
The timeline typically runs 6–10 weeks: • Site visit & design: 1–2 weeks to assess roof, shade, and electrical panel. • Permitting & interconnection approval: 2–4 weeks with the Town of Jonesborough and BrightRidge/TVA. • Installation: 1–3 days on the roof plus 1 day for electrical work. • Inspection & utility meter swap: 1–2 weeks after installation. Once the utility grants permission to operate (PTO), you can turn on the system and start producing your own power.
How much maintenance do solar panels need and how long will they last?
Solar PV systems are largely maintenance-free. The panels have no moving parts and are built to withstand hail up to 1″ and winds up to 120 mph—well beyond typical Jonesborough weather events. Rinsing them with a garden hose a few times a year or after heavy pollen season is usually enough. Inverters may need replacement after 12–15 years, but many newer models come with 25-year warranties. Overall, panels are warrantied for 25–30 years and often keep operating at 80 %+ efficiency for 35–40 years.
Will my solar system keep the lights on during a power outage?
A standard grid-tied system automatically shuts down during an outage for line-worker safety. If you want backup power, you can add a battery storage package or a hybrid inverter. With batteries, critical loads—such as lights, refrigerator, Wi-Fi, and medical equipment—can stay powered for several hours or even days depending on battery capacity. We design custom backup solutions and can model how long your selected loads will run during a typical Jonesborough outage.
