Local Solar & Battery Guide
Solar in Nashville works differently than solar out West. You get about 4.8 peak sun hours a day, long humid summers that keep the AC running, and a power company that does not credit your exports one for one. So the right Nashville system is built to power your own house while the sun is up and, with a battery, to keep the lights on when the grid goes down.
The Solar Roofers is a family-owned Nashville roofing and solar contractor working in Middle Tennessee since 2003. We got into solar after watching other crews damage our customers' metal roofs. We could not find a solar partner we trusted with our neighbors' homes, so we became one. One crew stands behind both your roof and your array.
The average Nashville household uses about 1,075 kWh a month, roughly $134 at about 12 cents per kWh. The heaviest use lands in July and August, when heat and humidity push air conditioners hard all afternoon. That is also when panels make the most power.
Nashville homeowners usually call us for one of three reasons:
Solar is not for every house. Heavy shade from mature oaks and maples, a mostly north-facing roof, or a roof with only a few years left can all make it a poor fit. If that is your house, we will tell you straight.
Nashville Electric Service (NES) serves all of Nashville and Davidson County, and like every local power company in Tennessee it buys its power from TVA. There is no traditional 1-for-1 net metering here, and TVA retired the old Green Power Providers buyback. NES runs NESolar Connect and NESolar Savings, limited programs that buy eligible excess solar under specific terms and caps. We size systems for self-consumption, not export.
The Nashville area sees roughly 5 to 7 outage-causing severe weather events a year: spring thunderstorms, straight-line winds, the occasional tornado and winter ice. In January 2026, Winter Storm Fern knocked out power to about 230,000 NES customers at the peak, roughly half the system. NES restored nearly all power about 13 days after the storm.
That is where a battery earns its keep. One Tesla Powerwall 3 typically covers essential loads like the fridge, freezer, lights, Wi-Fi and a gas furnace blower or a small mini-split for roughly 12 to 24 hours, longer when solar recharges it. Solar by itself shuts off in an outage to protect line crews. Solar with a battery keeps running.
East Nashville mixes old bungalows and Victorians with a lot of new infill, and parts of it sit inside Metro conservation overlays, so we check the design rules before we draw a layout. Inglewood's ranch homes often have long, low roof planes that take panels well, but the big street trees mean we model shade carefully.
Both neighborhoods pair older cottages and bungalows with tall, skinny new builds. Small roofs mean every panel counts, so layout and panel efficiency matter more here than on a sprawling suburban roof.
Belmont's older homes sit under some of the biggest trees in town, and the Belmont-Hillsboro area has its own conservation zoning. Green Hills brings larger homes, complex rooflines and heavy electric loads, which often makes a battery part of the plan.
Bellevue's hillside subdivisions off Highway 70 can have good south and west exposure, but wooded lots and steep driveways take planning. Many streets here have HOAs, so we prepare clean, color-matched layouts for review.
Mid-century ranch homes on generous lots are common in Donelson and Madison. Simple gable roofs keep rooftop installs straightforward, and bigger lots sometimes leave room for a ground-mounted array.
Planning ranges, installed, before incentives. Not quotes.
Here is a worked example. A 10 kW array on a Nashville home runs about $28,500 – $35,000 installed and makes roughly 13,500 to 14,500 kWh a year. Add one Powerwall 3 and the project lands around $43,900 – $50,400 before incentives. Because NES does not credit exports one for one, we often recommend a slightly smaller array paired with a battery instead of the biggest system your roof can hold.
There is no federal homeowner tax credit for these numbers. The 25D credit ended for systems installed after December 31, 2025.
A solar array is a 25-year investment. Your roof has to last at least that long under it. Never put a 25-year array on a roof with only a few years left. If your roof is close, we plan the roof first.
On standing seam metal, panels attach with S-5! style clamps right on the seams. No roof penetrations. On shingles, every mount is lagged into the rafters and flashed, often 40 to 80 penetrations on a typical array.
Need a new roof after the panels go up? Removing and reinstalling an array typically costs $3,000 – $6,000. That is why it often makes sense to pair solar with a new metal roof. One crew, one warranty for roof and solar.
Can I still get the federal solar tax credit in 2026?
Not on a system you own. The 25D homeowner credit ended for systems installed after December 31, 2025. Leased systems and PPAs may still carry the business 48E credit through 2027. Confirm your situation with a tax professional.
Will a battery get me through an outage like Winter Storm Fern?
It will keep your essentials running. One Powerwall 3 typically covers the fridge, freezer, lights, Wi-Fi and a gas furnace blower for roughly 12 to 24 hours, longer when solar recharges it each day. NES took about 13 days to restore nearly all power after Fern, so pairing the battery with solar matters.
Does NES pay me for extra solar power?
Only in limited ways. NESolar Connect and NESolar Savings buy eligible excess solar under specific terms and caps. There is no 1-for-1 net metering, so we size systems to power your home, not to sell back.
Can I put solar on a house in a historic overlay or HOA?
Often, with the right placement, but it depends on the rules. Parts of East Nashville and the Belmont-Hillsboro area have overlay guidelines, and many Bellevue and Green Hills subdivisions have HOAs. We check the rules and prepare drawings before anything goes on the roof.
