Mt. Juliet Solar Panel and Battery Installer

Mt. Juliet sits between two lakes, Old Hickory to the north and Percy Priest to the south, and it has filled in fast with newer subdivisions on both sides of Interstate 40. Many homes here are newer than the ones in Nashville, with open lots and simpler roofs. That makes a lot of Mt. Juliet a good place to put solar to work.

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. Wilson County is a straight shot out I-40 from our shop on East Trinity Lane.

Solar and Battery Backup Built for Mt. Juliet

The average Nashville-area household uses about 1,075 kWh a month, roughly $134 at about 12 cents per kWh. Bigger two-story Mt. Juliet homes with open floor plans often use more than that through the hot, humid summer. Panels make their most power on those same long afternoons, so solar offsets your highest-use hours.

Three reasons Mt. Juliet homeowners call us:

• Lower summer bills from daytime solar that covers AC load.
• Storm backup. Folks here remember the March 2020 tornado and the ice of Winter Storm Fern.
• Doing it right the first time on a newer roof, or planning solar into a roof replacement.

Solar is not a fit for every Mt. Juliet house. Tight townhome roofs, heavily wooded lots near the lakes, or a roof that faces mostly north can make the numbers weak. We will tell you straight.

Mt. Juliet Power, Weather and Outages

Mt. Juliet is served by two TVA power companies: Middle Tennessee Electric (MTE) and Nashville Electric Service (NES). Which one you have depends on your street, so check the name on your bill. It matters for interconnection paperwork and any buyback terms.

Tennessee has no traditional 1-for-1 net metering, and TVA retired the old Green Power Providers buyback. NES customers can look at NESolar Connect and NESolar Savings, limited programs that buy eligible excess solar under specific terms and caps. MTE members should plan on limited export value as well. Either way, we size systems for self-consumption.

The area sees roughly 5 to 7 outage-causing severe weather events a year: spring thunderstorms, high 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, and NES restored nearly all power about 13 days after the storm. One Tesla Powerwall 3 typically covers 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 without a battery shuts off when the grid goes down.

Solar Across Mt. Juliet Neighborhoods

Providence

Providence is a master-planned community around the Providence Marketplace area, with newer homes and clean roof planes. HOA guidelines shape panel color and placement, and we prepare layouts that fit them.

Del Webb Lake Providence

This 55+ lakefront community has single-story and low-profile homes. Smaller roofs mean careful layout, and a battery is often the priority for owners who want the lights and medical equipment to stay on.

Willoughby Station

Willoughby Station has larger homes on established streets with some mature trees. Big roof areas give room for panels, and shade modeling tells us which planes to use.

Jackson Hills and Kelsey Glen

These newer subdivisions have young trees and simple gable roofs, which often makes them strong rooftop candidates. Both have HOAs, so we handle the review packet.

Nichols Vale

Nichols Vale mixes family homes on moderate lots. Many roofs are still young enough to carry an array for years, and we confirm that before we design.

What Solar and Batteries Cost in Mt. Juliet

Installed planning ranges before incentives. These are not quotes:

• Residential solar: $2.85 – $3.50 per watt. Typical home systems are 8 to 14 kW, about $22,800 – $49,000 installed, producing about 11,000 to 19,000 kWh a year.
• Tesla Powerwall 3: about $15,400 installed, 13.5 kWh per unit, 10-year warranty.
• Enphase IQ Battery: $12,000 – $18,000 installed, 5 or 10 kWh units, 15-year warranty.
• Roof and solar together: typically saves $2,000 – $5,000 through shared permits, wiring, crew and scaffolding.

Worked example: an 11 kW array on a two-story Providence home runs about $31,350 – $38,500 installed and makes roughly 14,850 to 15,950 kWh a year. Add one Powerwall 3 at about $15,400 for essential backup.

There is no federal homeowner tax credit in 2026. The 25D credit ended for systems installed after December 31, 2025.

Roof First: Solar on Metal and Shingle Roofs in Mt. Juliet

Plenty of Mt. Juliet roofs are shingle, and many are fairly young. Young or not, we inspect first. Never put a 25-year solar array on a roof with only a few years left, because removing and reinstalling the array for a later re-roof typically costs $3,000 – $6,000.

On shingles, every mount is lagged and flashed, often 40 to 80 penetrations on a typical array. On standing seam metal, S-5! style clamps grab the seams and the roof never gets a hole. If you are close to needing a roof, plan the roof with us first. One crew, one warranty for roof and solar.

Our Mt. Juliet Solar Process

• Assessment. We inspect the roof and attic, model shade and review a year of MTE or NES bills.
• Design and written proposal. A layout, production estimate and line-by-line written price, with HOA documents if needed.
• Permits and interconnection. We handle City of Mt. Juliet permits and the MTE or NES interconnection, usually 2 to 6 weeks.
• Roof work if needed. If the roof is due, it comes first. Roof and solar together take about 2 to 3 weeks.
• Installation. Rooftop solar takes 1 to 3 days on site, or 2 to 4 days with batteries and panel work.
• Inspection, turn-on and walkthrough. After inspection and utility approval, we turn it on and walk you through monitoring and backup.

Common Mt. Juliet Solar Questions

Can I still get a federal tax credit for solar in 2026?
Not for a system you own. The 25D homeowner credit ended for systems installed after December 31, 2025. Leases and PPAs may still carry the business 48E credit through 2027. Talk with a tax professional.

What does a battery do for me in a storm outage?
It keeps essentials running. One Powerwall 3 typically handles the fridge, freezer, lights, Wi-Fi and a gas furnace blower for roughly 12 to 24 hours, and solar can recharge it each day during a longer outage.

Am I on MTE or NES?
Look at your electric bill. We confirm it during the assessment, since interconnection and buyback terms depend on it.

Will my HOA allow solar?
It depends on your HOA's rules. Most care about color, placement and visibility, and we prepare the drawings and spec sheets they ask for.
