Why Knoxville Residents and Businesses Are Going Solar
Knoxville and East Tennessee are waking up to a new energy reality. For decades, TVA power delivered through Knoxville Utilities Board (KUB) was some of the cheapest electricity in America—but those days are rapidly fading. TVA wholesale rates have increased significantly in recent years, driven by massive infrastructure investments to modernize the aging grid, retire coal plants, build new natural gas and nuclear capacity, and respond to soaring demand from data centers and industrial growth across the Tennessee Valley. KUB residential rates now average 12–16 cents per kWh and are projected to continue climbing for the foreseeable future. Meanwhile, Knoxville's position in the upper South Tennessee Valley delivers excellent solar resources—approximately 4.6 peak sun hours daily with 205+ sunny days annually—producing 15–30% more energy per panel than Great Lakes and Northeast markets. Tennessee's no-state-income-tax advantage means the full value of your 30% federal ITC stays in your pocket. Combined with TVA's distributed generation programs, Tennessee's property tax considerations, and Knoxville's strong solar production, East Tennessee offers an increasingly compelling case for solar—especially as the era of cheap TVA power comes to an end.
💰
The End of Cheap TVA Power — Rising KUB Rates
Knoxville Utilities Board distributes power purchased wholesale from the Tennessee Valley Authority, and for generations, TVA's hydroelectric legacy kept rates among the lowest in America. That era is ending. TVA rates have surged in recent years—driven by tens of billions in infrastructure investment to replace aging coal plants, build new natural gas and nuclear generation, upgrade transmission and distribution across the seven-state service territory, and meet explosive new electricity demand from data center construction and industrial reshoring across the Tennessee Valley. KUB residential rates now average 12–16 cents per kWh and have increased approximately 30–40% over the past decade, with multiple rate increases in recent years and more projected ahead. Summer electricity bills spike when Knoxville's hot, humid weather drives heavy air conditioning loads—monthly bills exceeding $200–$300 are common for typical homes during June through September. Solar locks in your energy costs at today's prices for 25+ years, protecting you from TVA's structural rate increases that show no sign of slowing down. Businesses face commercial rates of 10–14¢/kWh plus demand charges that make commercial solar increasingly attractive as TVA's wholesale costs climb.
⛈️
Severe Weather, Tornadoes & Valley Flooding
East Tennessee experiences a full spectrum of severe weather that regularly challenges grid reliability: intense summer thunderstorms with damaging straight-line winds, large hail, and dangerous lightning, tornado activity as the Tennessee Valley sits within the region sometimes called Dixie Alley (one of the most active severe weather corridors in the Southeast), mountain-valley wind channeling that intensifies storm systems funneling through the Great Smoky Mountain gaps and ridgelines, winter ice storms that coat the ridges and valleys with destructive ice loading, and heavy rainfall events that drive flooding along the Tennessee River tributaries and Knoxville's creek systems. The 2020 tornado outbreak demonstrated East Tennessee's vulnerability with devastating effect. KUB's distribution grid winds through heavily treed neighborhoods and steep terrain—a combination that makes power lines particularly vulnerable to tree failures during any severe weather event. Battery storage and generator backup provide essential protection: keeping air conditioning running during dangerous summer heat waves, maintaining heating during winter ice storm outages, powering sump pumps during heavy rainfall and flooding, preserving food and medications, and ensuring business continuity during the storms that impact the Tennessee Valley multiple times annually.
☀️
Excellent Upper-South Solar Resources
Knoxville receives approximately 4.6 peak sun hours daily and around 205 sunny days annually—excellent solar resources that significantly outperform Northern and Great Lakes markets. The Tennessee Valley's upper-South latitude delivers strong year-round production: long, intense summer days with 14.5+ hours of daylight driving outstanding June–August generation, solid spring and fall performance, and mild winters that avoid the extreme cold and heavy snow cover that limit production in Northern states. Well-designed systems generate 1,200–1,400 kWh annually per installed kW—15–30% more energy per panel than Cleveland, the Great Lakes, or New England markets. Knoxville's warm climate means high air conditioning demand aligns naturally with peak solar production—your system generates the most energy precisely when your electricity consumption and KUB bills are highest. Mild winter temperatures also keep panels operating efficiently without the extreme cold-weather stress that challenges equipment in Northern states, contributing to excellent long-term panel longevity in the Tennessee Valley's moderate climate.
📋
No State Income Tax, Federal Credit & TVA Programs
The 30% Federal Investment Tax Credit remains available through 2032—and Tennessee's no-state-income-tax advantage means the full credit value stays in your pocket without state tax complications, just like residents of South Dakota, Wyoming, and Washington. TVA offers distributed generation programs through KUB that allow customer-owned solar systems to connect to the grid, with various rate structures and buyback options for excess generation that have evolved as TVA adjusts to the growing solar landscape. Tennessee doesn't impose state sales tax specifically on solar energy equipment through various exemption provisions, providing additional savings. While Tennessee doesn't currently offer a state-level solar tax credit, the combination of no state income tax preserving your full federal ITC, TVA/KUB generation programs, property tax considerations, and excellent solar production creates a solid financial picture. Commercial installations qualify for accelerated MACRS depreciation, recovering 85% of costs within six years. For rural East Tennessee properties, USDA REAP grants covering up to 25% of system costs are available, stacking with the federal ITC for combined 55%+ cost reduction for qualifying agricultural and rural business operations.

Real results from homeowners, contractors, and businesses throughout Knox County and East Tennessee.
"I grew up thinking TVA power was dirt cheap—and it was, for a long time. But our KUB bills kept going up and up. We hit $310 in July with the AC running, and that was the last straw. Our 9.5kW system now covers virtually all our electricity, and the KUB bill dropped from $215 average to under $18 with generation credits. The 30% federal credit was clean and simple with no Tennessee state income tax. First-year production beat projections by 4%—turns out East Tennessee sunshine is better than people think. The battery kept our AC running through a 14-hour outage during a July thunderstorm when it was 96°F. Cheap TVA power is over, but solar gives us the next best thing—our own power plant on the roof."
Emily T.Farragut Homeowner
"The solar market in East Tennessee has completely changed. Three years ago, people still thought TVA power was cheap—now they're getting their KUB bills and calling me. PES materials arrive via I-40 in 48 hours, PowerLink pricing keeps my margins healthy, and their technical team understands TVA interconnection requirements and the humidity engineering that's critical down here. I've tripled my installation volume since TVA started raising wholesale rates aggressively. The conversation is easy now: show homeowners their KUB rate trajectory, show them the 30% credit with no state income tax, and the math closes itself. Knoxville is becoming one of the strongest solar markets in the Southeast."
David M.Solar Contractor, East Tennessee
"Our distribution center off I-75 was paying $11,200 monthly to KUB—base rates plus demand charges on our dock operations, climate control, and lighting. With TVA raising wholesale rates and KUB passing them through, we could see costs climbing for years. PES designed a 195kW rooftop system across our flat warehouse roof. First-year savings hit $68,000—a 58% reduction in electricity costs. The federal credit and MACRS depreciation with no Tennessee corporate income tax made the financial case overwhelming, with payback tracking at 4.2 years. We've been telling every logistics and manufacturing operation in the Knoxville market that the solar math at current KUB rates is exceptional. The era of cheap TVA power is over, but solar fills that gap."

Tennessee's no-state-income-tax advantage ensures more of the 30% federal credit benefit flows directly to you compared to residents of most other states. Commercial installations typically achieve strong positive cash flow within the first year when combining the federal ITC, MACRS depreciation (enhanced by Tennessee's no-corporate-income-tax status), and KUB cost reductions—with payback periods often under 5 years for energy-intensive manufacturing and logistics operations along the I-40/I-75 corridor.
Knoxville's East Tennessee location in the upper South delivers excellent solar resources—significantly better than most people expect and substantially stronger than Northern and Great Lakes markets. The Tennessee Valley's combination of strong sunshine, long summers, and mild winters creates an ideal environment for solar energy production.
Knoxville Solar Performance Factors:
Annual production: Well-designed systems generate 1,200–1,400 kWh per installed kW—15–30% more per panel than Cleveland, the Great Lakes, or New England markets
Peak sun hours: 4.6 hours daily average, with summer months exceeding 6 hours—excellent for the upper South and competitive with many traditionally strong solar markets
Summer alignment: Peak solar production occurs during May–September when Knoxville's air conditioning demand drives highest electricity consumption and most expensive KUB bills—your system produces the most energy exactly when you need it most and when it's worth the most
Long production season: East Tennessee's mild climate provides strong year-round generation, with productive months from March through October and meaningful output even in December and January
Mild winter advantage: Tennessee's moderate winters avoid the extreme cold, heavy snow, and prolonged overcast that reduce production in Northern states—panels rarely face extended snow coverage or below-zero efficiency concerns
Heat pump synergy: Knoxville's mild winters make heat pumps exceptionally efficient—pairing solar with a heat pump provides the most cost-effective path to total energy savings in the Tennessee Valley
The Rising Rate Multiplier:
The financial story in Knoxville is increasingly about the rate trajectory. As TVA wholesale costs climb and KUB passes increases through to ratepayers, every kilowatt-hour your system generates becomes worth more each year. A system installed today at 14¢/kWh savings will be displacing 18–22¢/kWh electricity within a decade if current rate trends continue—making the effective return on your solar investment grow over time rather than diminish. This is the fundamental financial argument for going solar in the Tennessee Valley now: lock in today's costs before the era of rising TVA rates makes electricity significantly more expensive.
Real Knoxville System Performance:
A typical 9kW residential system in Knoxville produces approximately 11,000–12,600 kWh annually—enough to offset 80–100% of average household consumption. Combined with the 30% federal ITC (preserved by Tennessee's no-state-income-tax advantage), TVA/KUB generation programs, and rising rates that increase the value of every kilowatt-hour over time, Knoxville delivers payback periods of 8–11 years residential and 5–8 years commercial—among the strongest solar returns in the Southeast and accelerating as TVA rates continue climbing. The Tennessee Valley's solar future is bright—and the homeowners and businesses who invest now will benefit the most as the gap between rising grid rates and fixed solar costs widens every year.
