FAQs
How much can I expect to save on my electric bill after going solar in Greeneville?
Savings vary with roof size, panel orientation, shading, and your current electric-rate tier, but most Greeneville homeowners offset 55-75 % of their annual electricity consumption. For a typical 7 kW residential system this translates into $80–$110 in monthly bill reductions, or $1,000–$1,300 a year. Because Greeneville Light & Power’s kWh rate has risen roughly 2 % per year over the past decade, the dollar value of those savings generally grows over time.
What incentives or tax credits are available for solar installations in Greeneville?
The 30 % Federal Investment Tax Credit (ITC) applies to both equipment and labor on qualified solar projects placed in service through 2032. Tennessee does not levy additional state incentives, but solar equipment is 100 % exempt from state sales tax when installed by a licensed contractor. In addition, Greeneville residents can apply to sell excess generation to TVA under the Dispersed Power Production (DPP) program, receiving an avoided-cost rate for every kWh exported to the grid. Check with your tax professional and utility for current program specifics.
How does the grid-tie process work with Greeneville Light & Power System (GLPS)?
1) We design your system and submit an interconnection application to GLPS/TVA on your behalf. 2) GLPS reviews the plans, performs a site visit if necessary, and issues an interconnection agreement. 3) After installation our electricians schedule the final electrical inspection and GLPS swaps your existing meter for a bi-directional meter. 4) Once GLPS gives written approval, we energize the array and you start producing power. The entire utility paperwork and approval stage typically takes 4–6 weeks.
Will my solar panels keep producing during power outages or on cloudy days?
Panels still generate electricity whenever there is daylight, but output drops to 10–30 % of their rated capacity on heavily overcast days. For safety reasons, a standard grid-tied system automatically shuts down if the utility grid goes offline; this prevents back-feeding and protects lineworkers. If you want backup power during outages, we can incorporate a battery storage package or a hybrid inverter that isolates your home from the grid and lets your array keep running.
What maintenance do solar panels require in Greeneville’s climate?
Solar PV is largely maintenance-free. Annual rainfall usually keeps modules clean, but if pollen or dust accumulate you can rinse panels with a garden hose from the ground. We recommend: (1) a visual inspection every spring, (2) checking the online monitoring portal monthly for performance alerts, and (3) trimming nearby trees that could cause shading. All our panels carry a 25-year production warranty and the racking is rated for 120 mph wind gusts—well above Greene County’s building code requirements.
How long does it take for a solar investment to pay for itself in Greeneville?
Most residential customers see simple payback in 8–12 years. Key factors are system size, electric-rate escalation, and whether you can fully use the 30 % ITC. A 7 kW system costing $22,000 before incentives would have a net cost of about $15,400 after the tax credit and would generate roughly $1,200 in first-year savings and TVA export payments, yielding an initial 7.8 % return and complete payback in just under 9 years. Because panels are warrantied for 25 years, more than two-thirds of their useful life produces pure savings.
