FAQs
Is Johnson City sunny enough for solar panels to be cost-effective?
Absolutely. Johnson City receives an average of 4.5–5.0 peak sun-hours per day, which is comparable to other successful solar markets in the Southeast. A well-sited 6 kW residential array typically generates 7,500–8,000 kWh per year—roughly 75–90 % of an average home’s annual electricity use—making solar both viable and financially attractive here.
What incentives or rebates are available for Johnson City residents who go solar?
1. Federal Investment Tax Credit (ITC) – 30 % of the installed cost for systems placed in service before 2033. 2. TVA Green Connect Program – Up-front performance-based credits for every kWh your system produces (amount varies annually). 3. BrightRidge Net Billing – You receive bill credits at the avoided-cost rate for surplus power exported to the grid. 4. Sales-tax Exemption – Solar equipment is exempt from Tennessee sales tax when installed by a licensed contractor. 5. Local Property-Tax Relief – Washington and Carter counties currently do not reassess property value increases due to a solar installation.
How does net metering/billing work with BrightRidge and TVA?
Johnson City is served by BrightRidge, which participates in TVA’s "Dispersed Power Production" model. Your system first powers your home; any excess flows to the grid through a bidirectional meter. You receive monthly bill credits for exported kWh at TVA’s avoided-cost rate (around 3–4 ¢/kWh). Credits can offset your consumption charges but not fixed fees. Because the export rate is lower than the retail rate (≈11 ¢/kWh), right-sizing your array to match on-site usage maximizes savings.
What is the typical installation and permitting timeline in Johnson City?
• Site visit & proposal: 1 week • HOA & engineering review (if required): 1–2 weeks • Permit application with Johnson City Building Division: 5–10 business days • TVA/BrightRidge interconnection approval: 2–3 weeks (may run concurrently with city permit) • Installation: 1–2 days for most residential systems • Final inspection & meter swap: 3–7 days after installation • Permission to Operate (PTO): usually granted the same day the new meter is installed Total time from contract to energization averages 6–8 weeks, depending on utility and inspector backlogs.
How much maintenance do solar panels require in our region?
Solar PV has no moving parts, so upkeep is minimal. Rainfall in Northeast Tennessee generally keeps modules clean, but we recommend a rinse with a soft nozzle once or twice a year if pollen or dust buildup is visible. Annual maintenance checks include: • Visual inspection of wiring & roof penetrations • Torque testing of racking hardware • Inverter firmware updates and performance review These tasks are covered in our optional low-cost service plan, but many owners prefer a DIY visual check and remote monitoring using the included app.
Will my solar array provide power during outages, and what are my battery options?
A standard grid-tied system shuts off automatically when the grid goes down for safety reasons. To keep critical loads running, you can add a battery storage system such as Tesla Powerwall or Enphase IQ Battery. Popular configurations in Johnson City include a 10–20 kWh battery bank, which can power essentials (refrigerator, lights, Wi-Fi, medical equipment) for 12–24 hours. During prolonged outages, daytime solar generation automatically recharges the batteries. Battery installations qualify for the same 30 % federal tax credit, further improving the economics.
