FAQs
What are the main benefits of installing solar panels on my Harriman property?
Going solar in Harriman lets you cut or even eliminate your monthly power bill, hedge against future utility-rate increases, and lower your carbon footprint. Because Harriman is served by the TVA grid, residential kWh rates average 11–12¢, so every kilowatt-hour your array produces is real money saved. A typical 6 kW system offsets about 8,500 kWh per year, preventing roughly 6 tons of CO₂ emissions—the same as planting 150 trees annually—while boosting home value and making you less dependent on the grid.
How does your solar installation process work from start to finish?
1) Site Assessment – We inspect your roof or ground space, measure usable sun hours with a shade-analysis tool, and check your electrical service panel. 2) Custom Design – Our NABCEP-certified designers size the array, select equipment, and prepare CAD drawings and energy-production estimates. 3) Permitting & Utility Paperwork – We handle City of Harriman permits, Roane County inspections, and TVA/HUB interconnection forms so you don’t have to. 4) Installation – A licensed electrician and solar crew mount the racking, panels, inverter(s), and all code-compliant wiring—most residential jobs are done in 1–2 days. 5) Inspection & Commissioning – The local inspector signs off, the utility installs a bi-directional meter, and we energize the system while showing you the monitoring app. 6) Ongoing Support – We monitor production remotely and stay on call for any questions for the life of the system.
What incentives, tax credits, or rebates can Harriman residents receive?
• Federal Solar Investment Tax Credit (ITC) – Through 2032 you can claim 30 % of the total system cost as a dollar-for-dollar credit on your federal income taxes. • TVA Green Connect – TVA currently pays a one-time performance-based incentive of $500 to systems installed by approved contractors (we’re on the list). • Sales- & Property-Tax Savings – Tennessee exempts solar equipment from state sales tax and does not reassess property value for tax purposes for the first 12 years. • Local Financing – The HUB offers on-bill financing and several Harriman-area credit unions have low-interest “Energy Efficiency” loans requiring no home equity.
How much roof space and sunlight do I need for a residential solar array?
A rule of thumb is 100 sq ft of unshaded roof per 1 kW of panels. A typical 6 kW array needs about 600 sq ft of south-, southeast-, or southwest-facing roof with less than 15 % shading between 9 a.m. and 3 p.m. yearly. If your roof is smaller or shaded by trees, we can design a high-efficiency panel layout, split the array across multiple roof sections, or install a ground-mounted system in your yard.
What maintenance is required and what warranties do you provide?
Solar electric systems have no moving parts, so routine upkeep is minimal—just rinse panels with a garden hose a few times a year if dust or pollen builds up. We include free system monitoring, and if output drops we’ll alert you. Panels carry a 25-year performance warranty (at least 84 % output in year 25) and a 12-year product warranty that we extend to 25 years on most models. String inverters have 12-year warranties (upgradeable to 25), while microinverters and DC optimizers are backed for 25 years. Our workmanship warranty covers roof penetrations and electrical labor for 10 years.
Will my solar array power my home during a grid outage and how does net metering work here?
Standard grid-tied systems shut off automatically during an outage for safety, but you can add a battery-backup package that keeps critical loads (fridge, lights, outlets, internet) running for hours or days. For net metering, Harriman Utility Board uses TVA’s simplified interconnection policy: any excess energy flows to the grid and spins your bi-directional meter backward at the full retail rate. Energy you export in one month offsets what you import later in the same billing cycle, allowing you to zero out the energy portion of your bill (fixed customer charges still apply).
