FAQs
Why is Collegedale a good place to go solar?
Collegedale receives an annual average of more than 210 sunny days, which translates to strong solar production throughout the year. Local electric rates from EPB and Volunteer Energy Cooperative have risen about 3–4 % annually over the past decade, so producing your own power helps lock in lower energy costs. In addition, Tennessee has no state income tax on solar-derived savings, and solar equipment enjoys a 100 % property-tax exemption, making the city an attractive market for residential and commercial solar arrays.
How much can I expect to save by installing solar panels on my home or business?
Savings depend on system size, roof orientation, shading, and your current electric usage. A typical 7 kW residential array in Collegedale produces roughly 9,500 kWh per year. At an average utility rate of $0.13 per kWh, that equals about $1,235 in annual bill avoidance. With the 30 % Federal Investment Tax Credit (ITC) and local net-metering credits, most homeowners see payback periods of 8–10 years and a 20- to 25-year lifetime savings of $25,000–$35,000. Commercial clients often realize even shorter paybacks thanks to accelerated depreciation (MACRS) and TVA performance payments.
What incentives and financing options are available for Collegedale solar projects?
• Federal 30 % Investment Tax Credit (ITC) on all equipment and labor costs. • Modified Accelerated Cost Recovery System (MACRS) depreciation for businesses, yielding roughly another 20–25 % tax benefit. • TVA Green Connect program offers performance-based energy credits for systems up to 50 kW. • Local lenders such as Southeast Bank and EPB Energy Pros provide low-interest solar loans with terms up to 15 years. • PACE (Property Assessed Clean Energy) financing is available for qualifying commercial properties, allowing repayment through property tax assessments.
What is the installation timeline and what should I expect during the process?
1. Site Assessment (1–2 hours): Our NABCEP-certified team measures roof space, shading, and electrical service. 2. Proposal & Contract (2–3 days): You receive a detailed quote, production estimate, and financing options. 3. Engineering & Permitting (2–4 weeks): Structural drawings, electrical line diagrams, and permits are filed with Collegedale Building and Codes and TVA. 4. Installation (1–3 days for residential; 1–2 weeks for large commercial): Panels, racking, inverters, and wiring are mounted and tied into your main service panel. 5. Inspection & Interconnection (1 week): City inspectors and the utility review the system before issuing a Permission to Operate (PTO). From signed contract to PTO typically takes 5–8 weeks for homes and 8–12 weeks for commercial arrays.
Will my solar panels work during power outages, and can I add batteries?
For safety, grid-tied solar inverters automatically shut down when the grid is offline, so panels alone will not power your home during an outage. Adding a battery storage system—such as Tesla Powerwall, Enphase IQ Battery, or LG ESS—creates a hybrid setup that can supply critical loads (refrigerator, lights, internet, medical devices) for several hours to several days, depending on capacity. Our designers size batteries based on your outage-protection goals and help you qualify for the same 30 % federal tax credit on storage when installed with solar.
How much maintenance do solar panels require, and what warranties are included?
Solar PV systems are largely maintenance-free. Seasonal rain keeps panels clean, but a quick rinse during pollen season can boost production 2–3 %. We provide a free annual performance check for the first three years and offer low-cost monitoring plans thereafter. Manufacturers back modules with 25- to 30-year performance warranties (guaranteeing at least 80–90 % output in year 25) and 12- to 25-year product warranties. Inverters carry 10–25-year warranties depending on model, and we include a 10-year workmanship guarantee on all labor, roof penetrations, and electrical connections.
