FAQs
Does Collegedale get enough sunshine for solar panels to be worthwhile?
Yes. Collegedale averages about 4.5–5.0 peak sun-hours per day throughout the year, which is on par with much of the Southeast. A well-designed 6-kW residential array can produce roughly 8,000–9,000 kWh annually—close to the average household’s yearly use. Modern high-efficiency panels also perform well in our partly-cloudy spring and fall months, so solar remains cost-effective even when the sky isn’t perfectly clear.
What incentives or rebates are available to Collegedale homeowners and businesses who go solar?
1. Federal Solar Investment Tax Credit (ITC) – 30 % of the installed cost can be claimed against your federal income tax through 2032. 2. TVA Green Connect – Tennessee Valley Authority provides a one-time $500 rebate for qualifying installations and streamlines interconnection for local EPB/Volunteer Energy Cooperative customers. 3. Sales-tax exemption – Tennessee waives the 7 % state sales tax on most solar equipment. 4. Property-tax exemption – Solar improvements are 100 % exempt from property-tax assessments in Hamilton County, so your tax bill will not rise when you add panels. 5. Accelerated depreciation (MACRS) – Businesses can depreciate 100 % of the system in year one, creating significant cash-flow benefits.
What is the step-by-step solar installation process with your company in Collegedale?
1. Free Solar Assessment – We analyze your roof, bills, and goals using satellite shading models and on-site measurements. 2. Custom Proposal – You receive a fixed-price quote, 25-year production estimate, and financing options within 48 hours. 3. Permitting & TVA Interconnection – Our team prepares engineering drawings, obtains the City of Collegedale building permit, and submits the TVA Green Connect interconnection application. This paperwork phase usually takes 2-3 weeks. 4. Installation – A typical 7-kW residential system is installed in 1–2 days by our NABCEP-certified crew. All wiring is completed by Tennessee-licensed electricians. 5. Inspection & Utility Swap – City inspectors approve the work; then TVA installs a bidirectional meter so you can export surplus power. 6. Activation & Monitoring – We walk you through your monitoring app and enroll the system in our 24/7 performance portal.
Will my solar panels provide power during a utility outage?
Standard grid-tied solar arrays shut down automatically when the grid goes down to protect line-workers (a UL-1741 requirement). If you want backup power, we can add a battery system—usually 10–20 kWh of lithium-ion storage—along with an automatic transfer switch. During an outage, the battery keeps critical loads (refrigerator, lights, Wi-Fi, medical equipment, etc.) running and the panels continue to recharge the battery each day. If you choose not to install batteries now, the system can be designed to be “battery-ready,” allowing you to add storage later without replacing inverters or rewiring.
How long will the entire solar project take and what local permits are required?
From signed contract to switch-on, most Collegedale residential projects complete in 6–8 weeks: • Engineering & Permitting – 2–3 weeks (City of Collegedale Building Inspection Division and Hamilton County electrical permit). • Equipment Procurement – 1 week (we stock most panels/inverters locally). • On-site Installation – 1–2 days. • Final Inspection & TVA Meter Swap – 2–3 weeks, depending on inspector and utility schedules. Commercial systems (rooftop or ground-mount) may take 8–12 weeks because of additional structural reviews and TVA demand-response studies.
What maintenance is required and what warranties do you provide?
Solar PV systems are largely maintenance-free—there are no moving parts. Rain usually keeps panels clean; if pollen buildup becomes visible, a quick rinse with a garden hose is sufficient. We recommend an electrical inspection and data check every 5 years, which we perform at no charge for customers. Our systems include: • 25-year manufacturer’s warranty on panels (minimum 84 % power output in year 25). • 25-year warranty on microinverters or 12-year standard/25-year extended on string inverters. • 10-year workmanship warranty covering roof penetrations, wiring, and racking. • 24/7 web monitoring with automated alerts—if production falls below threshold, we are notified and schedule service, usually within 48 hours.
