FAQs
How well does solar power perform in Signal Mountain’s climate?
Signal Mountain enjoys about 205–210 sunny days per year, which is above the national average. Even on partly cloudy days, modern photovoltaic (PV) modules generate energy thanks to high-efficiency cell designs and advanced inverters that capture diffuse light. A properly sized system can offset 90–100 % of an average home’s annual electricity consumption, making the area highly suitable for solar.
What is the typical process for getting a solar system installed by your team?
1) Site Evaluation – We visit your property to measure roof angles, shading, and electrical service. 2) Custom Design & Proposal – Using PV design software, we create a layout, production estimate, and financial projection. 3) Permitting & Utility Interconnection – Our permitting specialists handle Signal Mountain building permits, TVA Green Connect paperwork, and EPB/Sequachee Valley Electric applications. 4) Installation – Licensed electricians and NABCEP-certified installers mount the racking, modules, inverter(s), and monitoring hardware—usually in 1–2 days for residential jobs. 5) Inspection & Activation – After the city inspector and utility sign off, we power up the system and walk you through monitoring and maintenance guidelines.
What incentives are available to reduce the upfront cost?
Homeowners can claim the 30 % federal Investment Tax Credit (ITC) on the entire system cost, including batteries and roof reinforcements. Tennessee’s property tax exemption means the added value of solar is not taxed. Through TVA’s Green Connect, customers may qualify for a performance-based credit on every kWh exported. We also partner with local credit unions that offer low-interest solar loans with zero down payment, often keeping monthly loan payments below your previous electric bill.
How do battery storage options work with a grid-tied solar array?
Adding lithium-ion batteries (e.g., Tesla Powerwall or Enphase IQ Battery) allows you to store excess solar energy for nighttime use and provides backup during EPB/SVEC outages. The system remains grid-connected, so you can still draw power if batteries are depleted and send surplus energy back, earning bill credits. We size storage based on your critical loads—usually 10–30 kWh for essentials like refrigeration, lighting, and well pumps. Batteries add 30–40 % to project cost but enable greater energy independence and resilience.
What maintenance is required, and how long do solar panels last?
Solar PV systems are largely maintenance-free. Rainfall typically keeps modules clean; an annual visual inspection and occasional rinsing remove pollen or debris common in the Cumberland Plateau region. Inverters may require a firmware update every few years, which we handle remotely. Panels carry 25-year performance warranties (guaranteeing at least 80–85 % output) and often last 30+ years. We offer a 10-year workmanship warranty and optional monitoring service that alerts us if production drops so we can schedule a service call quickly.
How much can I save on my electric bill and how is ROI calculated?
Savings depend on system size, consumption patterns, and utility rates. A typical 8 kW residential array in Signal Mountain produces ~10,800 kWh annually. At the current average rate of $0.12/kWh, that’s about $1,300 in yearly bill avoidance. With the 30 % ITC and available financing, simple payback is 8–10 years, while panels continue producing free electricity for 20+ additional years. Internal Rate of Return (IRR) typically ranges from 8–12 %, outperforming many traditional investments and providing a hedge against future utility rate increases.
