FAQs
How much can I save on my electricity bills by switching to solar in Harriman?
Savings depend on your current utility rate, roof size, and energy consumption, but most Harriman homeowners offset 60 – 100 % of their annual electric bill. With TVA’s current residential rate of roughly 12–13¢/kWh and our average system size of 7 kW producing 9,500 kWh a year, that’s about $1,100–$1,250 in first-year savings. Because rates historically rise 2–4 % per year, lifetime savings over 25 years usually exceed $35,000. Our monitoring app shows real-time production so you can track every dollar you save.
What incentives and tax credits are available for solar installations in Harriman?
The 30 % Federal Investment Tax Credit (ITC) is the largest incentive; it applies to the entire turnkey cost, including panels, inverters, racking, batteries, and labor. Tennessee also exempts solar equipment from state sales tax, saving roughly another 9.5 %. In the City of Harriman, permit fees for solar are capped at $50, and TVA offers a small-scale generation credit that pays approximately 2 ¢/kWh for every unit you export to the grid for the first 10 years. We calculate all incentives in your proposal and provide the paperwork and step-by-step guidance for claiming them.
How long does a typical residential solar installation take from contract to energization?
Most projects follow a 5-step timeline: 1. Site audit & design (1 week) 2. Permitting and utility interconnection approval (2–4 weeks, depending on TVA and local inspectors) 3. Equipment ordering & logistics (1 week) 4. On-site installation (1–2 days for a standard 20-panel array) 5. Final inspection & utility meter swap (1–2 weeks) Overall, you can expect 4–8 weeks from signed contract to producing your own clean power. Commercial systems over 50 kW may take longer due to additional engineering and TVA review.
Will my roof qualify for solar panels, and what if it doesn’t?
We use high-resolution drone imagery and shade-analysis software to confirm structural integrity, tilt, orientation, and annual sun exposure. A good solar roof in Harriman ideally: • Faces south, southeast, or southwest • Has 200 ft² or more of unobstructed space • Receives at least 4.5 sun-hours per day on average If shading or limited space reduces production below 80 % of optimal, we can mount panels on an east-west layout, install a ground-mounted array, or incorporate high-efficiency modules that produce more power in tighter spaces. If your roof needs replacement within 5 years, we schedule re-roofing first and roll it into the solar financing so you still qualify for the 30 % tax credit.
What maintenance do solar panels require and what is their expected lifespan?
Solar PV systems are virtually maintenance-free. Harriman’s rainfall usually keeps panels clean; if visible dust or pollen buildup exceeds 10 %, a simple rinse with a garden hose will restore output. Inverters have built-in diagnostics and send alerts to our service team if performance drops. Panels are rated to last 25–30 years and carry 25-year production warranties guaranteeing at least 80–85 % of their original output in year 25. We include a 10-year workmanship warranty and offer affordable extended service plans for added peace of mind.
Can I add battery storage or EV charging to my solar system, and how does it work during power outages?
Absolutely. We integrate lithium-iron-phosphate batteries (Enphase IQ, Tesla Powerwall, or SolarEdge Home) that store excess solar power for evening use or backup. A typical 10 kWh battery can run essential loads—refrigerator, lights, Wi-Fi, and outlets—for 10–12 hours. Multiple units can be stacked for longer runtimes or whole-home backup. During a grid outage, an automatic transfer switch isolates your system, keeping the lights on without a noisy generator. For EV owners, we install Level-2 chargers that draw directly from your solar system, enabling truly emission-free driving. Both batteries and chargers qualify for the 30 % Federal ITC when installed with solar.
