FAQs
Is Gruetli-Laager sunny enough for a solar electric system to make sense?
Yes. Grundy County averages about 4.6–5.0 peak sun-hours per day, which is comparable to many places where solar is already common. A properly sized 6-kW rooftop array in Gruetli-Laager typically produces 8,000–9,000 kWh per year—more than half of the electricity used by an average Tennessee household. Our design team uses 25-year National Renewable Energy Laboratory (NREL) data and on-site shade readings to create an individualized production estimate before you sign a contract.
What incentives, rebates, or tax credits can I claim on a solar installation in Gruetli-Laager?
1. Federal Solar Investment Tax Credit (ITC): Through 2032 you can deduct 30 % of the total system cost—including panels, inverters, racking, labor, and batteries—directly from your federal income tax. 2. TVA Green Connect & Sequachee Valley Electric Cooperative (SVEC): TVA offers a one-time $1,000 rebate for systems installed by a Green-Connect-certified contractor (we are certified) and provides a simple interconnection path. 3. Accelerated Depreciation for businesses: Commercial systems can be depreciated in the first year under the Modified Accelerated Cost Recovery System (MACRS), plus a potential 10 % bonus credit if domestic-content thresholds are met. 4. Local Property-Tax Exemption: Tennessee law exempts the added value of renewable-energy equipment from county property tax assessments. We will supply all documentation and coordinate with your tax professional to ensure you receive every available benefit.
What permits, inspections, and utility approvals are required, and who handles them?
Solar projects in Gruetli-Laager fall under Grundy County’s building code and TVA’s interconnection rules. A typical approval sequence is: 1. Structural review of your roof or ground-mount foundation by a Tennessee-licensed engineer. 2. Electrical permit application filed with the Grundy County Building and Codes Department. 3. Interconnection agreement with SVEC/TVA (includes a $100 application fee and proof of liability insurance). 4. Rough electrical inspection during installation and a final inspection once the array is complete. 5. TVA witness test and meter swap so you can legally export power. Our project managers submit every form, track each approval, and meet inspectors on-site, so all you do is sign the final interconnection packet.
How does net metering (or bill crediting) work with Sequachee Valley Electric Cooperative and TVA?
TVA does not offer traditional one-for-one net metering. Instead, your solar production first powers your home in real time; any excess is exported and recorded on a bidirectional meter. Each exported kilowatt-hour (kWh) is credited at TVA’s avoided-cost rate—currently about 6–7¢/kWh—while the kWh you buy from the grid cost roughly 12–13¢. Because the credit is lower than the retail rate, we size systems to offset 60-90 % of your annual usage, maximizing self-consumption and your financial return. You will still receive a monthly bill, but it may be the minimum service charge only during high-production months.
Will my solar array keep the lights on during a power outage?
Grid-tied solar without batteries must shut down automatically when the grid fails (this is a safety requirement called "anti-islanding"). If you want backup power, we integrate lithium-ion battery storage—most commonly SunVault or Tesla Powerwall—so critical loads like refrigeration, lights, and medical devices stay on for several hours to multiple days, depending on battery capacity and weather. We’ll conduct a load-analysis to recommend the right battery size and show you how long your essential circuits can operate during an outage.
What maintenance is required and what warranties do you provide?
Solar PV systems are nearly maintenance-free. The tempered-glass modules are self-cleaning in normal rainfall; if dust or pollen builds up, a simple garden-hose rinse does the job. We include: • 25-year manufacturer warranty on panels (minimum 84 % power guarantee in year 25). • 25-year warranty on microinverters, or 12-year (extendable to 25) on string inverters. • 10-year workmanship warranty covering roof penetrations, wiring, and racking. • 24/7 online monitoring; we receive automatic alerts and dispatch technicians if production falls below projections. Most customers never need a service call, but if they do, labor is covered for the first ten years.
