FAQs
Is Cumberland Gap a good location for solar power, given its climate and terrain?
Yes. Cumberland Gap receives an average of 4–4.5 peak sun-hours per day, which is ideal for modern high-efficiency photovoltaic (PV) modules. Our state-of-the-art panels use bifacial, PERC, or N-type cell technology, allowing them to capture diffuse light reflected from the surrounding mountainsides as well as direct sunlight. The slight elevation also helps keep modules cooler, improving energy yield.
How do you determine the right system size and projected savings for my property?
We perform a free on-site assessment that includes shade analysis with drone lidar mapping, review of 12–24 months of utility bills, and load forecasting for future electric vehicle or HVAC upgrades. Using this data, our design software runs a 25-year production model that factors in local weather patterns, utility rate structures, and panel degradation. You receive a detailed proposal showing system size (kW DC), first-year production (kWh), payback period, internal rate of return (IRR), and environmental offsets in CO₂ equivalents.
What permits or approvals are required in the Cumberland Gap area, and do you handle them?
Installing solar in Cumberland Gap typically involves 1) a building or electrical permit from the city or county inspector, 2) an interconnection agreement with Powell Valley Electric Cooperative or your local utility, and 3) historic-district design review if your property lies within the National Historical Park buffer. Our project managers handle every step—including engineered drawings, structural stamps, and submission fees—so you only sign the final documents.
Can I choose between grid-tied, hybrid, and off-grid systems?
Absolutely. Most customers select a grid-tied system with net metering for the lowest upfront cost and fastest payback. If you need backup power for outages, we add lithium-iron-phosphate (LFP) batteries and a hybrid inverter, enabling seamless switchover in under 10 ms. Fully off-grid packages are also available, incorporating diesel or propane genset integration for extended autonomy. Our engineers walk you through pros, cons, and cost differences of each topology.
What incentives, rebates, or financing options are available for residents and businesses?
Homeowners and commercial clients can claim the 30 % Federal Investment Tax Credit (ITC) on the system cost, including batteries. Tennessee currently has no statewide solar rebate, but businesses may depreciate 85 % of eligible costs over five years using MACRS plus a potential bonus depreciation. Non-profits can apply for direct-pay elective refund of the ITC. We partner with credit unions for $0-down solar loans (5–20-year terms) and offer PPA or operating-lease structures for commercial arrays.
How long do the panels, inverters, and batteries last, and what maintenance is required?
Our Tier-1 modules carry a 25-year product warranty and a 30-year performance guarantee (minimum 87 % output in year 30). String inverters are warrantied for 12 years (extendable to 25), while microinverters come with 25-year coverage. LFP batteries have a 10-year/6,000-cycle warranty. The array has no moving parts; maintenance is limited to annual visual inspections and occasional washing if pollen buildup exceeds 5 % soiling. We offer optional monitoring and maintenance plans that alert you and our service team of any underperformance within minutes.
