Each glass solar tile produces 72 watts of power. The tempered glass is textured to resemble traditional roofing material while concealing the photovoltaic cells beneath. These are the power-generating tiles — strategically placed on south-facing, east-facing, and west-facing roof planes to maximize solar production throughout the day. Not every tile on the roof is a solar tile — only the tiles positioned where they will receive meaningful sunlight. This keeps costs lower than covering the entire roof with active tiles and ensures that every solar tile is actually earning its keep.
The non-solar portions of the roof are covered with architectural-grade steel tiles that provide corrosion resistance, weather protection, and longevity. These steel tiles are designed to visually match the glass solar tiles, creating a seamless appearance. They cover north-facing slopes, shaded areas, and any roof surface where solar production would be minimal — areas where paying for photovoltaic glass would not make economic sense.
Tesla Solar Roof also includes proprietary vent covers, ridge caps, and flashing components — all designed to integrate with the tile system. Every component is engineered as part of the system, not adapted from generic roofing parts. This integrated approach is what allows the roof to look like a roof rather than a science project.
Tesla Solar Roof comes with three separate 25-year warranties: a product warranty ensuring tiles will be free from manufacturing defects, a weatherization warranty covering the roof's ability to protect your home from the elements, and a power output warranty guaranteeing the system will produce at least 95% of its rated peak power after five years and lose no more than 0.5% per year for the remaining 20 years. That is 85% of rated output guaranteed at year 25 — a level of performance commitment that few roofing or solar products can match.
The current-generation Powerwall 3 is fundamentally different from previous versions. It includes an integrated solar inverter with six MPPT (Maximum Power Point Tracking) inputs, supporting up to 20 kW of DC solar input. This eliminates the need for a separate string inverter — reducing component count, simplifying installation, improving efficiency, and lowering overall system cost. The Powerwall 3 uses lithium iron phosphate (LFP) battery chemistry, which is safer, longer-lasting, and supports 100% depth of discharge — meaning you can use the full 13.5 kWh of stored energy, not just a portion of it.
Nashville averages several significant power outages per year from severe storms, tornadoes, and ice events. A single Powerwall can keep essential loads (refrigerator, lights, Wi-Fi, phone charging) running for 24–48 hours. Multiple Powerwalls or expansion units extend that to days — and if the sun comes out, the Solar Roof recharges the batteries automatically. Unlike a gas generator, there is no fuel to store, no engine to maintain, and no carbon monoxide risk.
Tesla's Storm Watch feature monitors weather forecasts and automatically pre-charges the Powerwall to 100% before severe weather arrives in your area. In Nashville's tornado season, this means your battery is fully charged before the storm hits — without you lifting a finger. The system then maintains that charge for outage protection rather than sending excess solar to the grid.
If your Nashville Electric Service (NES) rate structure includes time-of-use pricing or demand charges, Powerwall can optimize when you draw from the grid versus when you use stored solar energy — automatically shifting your consumption to minimize your bill.
Real-time monitoring shows exactly what your Solar Roof is producing, what your home is consuming, what is being stored in Powerwall, and what is being sent to or drawn from the grid. You can see this from anywhere — on your phone, at work, on vacation. The system learns your energy habits and adapts over time through over-the-air firmware updates.
For a typical Nashville home with a 2,000–2,500 square foot roof and an 8–12 kW solar system, the total installed cost of a Tesla Solar Roof — including tear-off of the existing roof, solar tiles, steel tiles, Powerwall, and all labor — ranges from approximately $70,000 to $120,000 before tax credits. This varies significantly based on roof complexity (number of planes, dormers, penetrations, and pitch), the ratio of solar tiles to steel tiles, and the number of Powerwall units.
The 30% federal Investment Tax Credit (ITC) applies to the solar-generating components — active solar tiles, the inverter, Powerwall, and their associated installation labor — but does not apply to the non-solar steel tiles or the tear-off of the existing roof. For a typical Nashville installation, the tax credit may reduce the effective cost by an estimated $15,000–$30,000+, depending on the solar portion of the project.
All pricing on this page represents general market ranges as of early 2026 and is provided for informational purposes only. Actual project costs depend on roof size, complexity, system configuration, Powerwall selection, structural requirements, permitting fees, and other site-specific factors. Tesla pricing is set by Tesla and is subject to change without notice. Request a formal project proposal for pricing specific to your home.
The 30% federal tax credit does not apply to the entire project cost. It applies only to the solar-producing components and their installation. On a $100,000 Tesla Solar Roof, the tax-credit-eligible portion might be $55,000–$70,000, yielding a credit of $16,500–$21,000 — not $30,000. This "split incentive" is the single most misunderstood aspect of Tesla Solar Roof pricing. We provide a clear breakdown showing exactly which line items qualify for the credit so there are no surprises at tax time.
The factors above are general observations based on our installation experience and are provided for informational purposes only. They do not constitute financial, investment, or tax advice. Whether Tesla Solar Roof or any solar product is appropriate for your situation depends on individual factors. Consult a qualified financial advisor for personalized guidance.
We present Tesla Solar Roof alongside traditional metal roofing, traditional solar panels, and metal-plus-panels as distinct options — each with different characteristics, costs, and tradeoffs. We help you understand the numbers for your specific home, your energy usage, and your priorities. We are roofers and certified solar installers — not financial advisors. We provide product and installation expertise; decisions about how to allocate your resources are yours to make with the guidance of qualified professionals.
Nothing on this page should be construed as a guarantee of energy savings, return on investment, or financial performance. Solar energy production, utility rate structures, tax incentives, property values, and insurance premiums are subject to change and are outside our control. All projections and estimates are illustrative only.
Glass solar tiles (the active, power-generating tiles), the integrated solar inverter, Powerwall battery storage (when installed with solar), solar-related electrical work and wiring, and the installation labor directly associated with these solar components.
Steel roofing tiles (the non-solar tiles), tear-off and removal of the existing roof, structural repairs or reinforcement, non-solar flashings and trim, and general roofing labor not directly related to the solar installation. These are conventional roofing costs, not solar costs, and are not covered by the ITC.
This example is for illustrative purposes only. Actual costs, eligible amounts, and tax credit values vary by project and individual tax situation. Consult a tax professional.
This credit is claimed on your federal tax return for the year the system is placed in service (powered on). You must have sufficient federal tax liability to use the credit — if your tax liability is less than the credit amount, the unused portion may be carried forward to subsequent tax years under current law. Tax laws are subject to change.
The information on this page regarding the federal Investment Tax Credit (ITC) is provided for general informational purposes only and does not constitute tax advice. Tax credit eligibility, applicable percentages, carry-forward rules, and qualifying expenditures depend on individual taxpayer circumstances and current federal tax law, which may change. The Metal Roofers is a roofing and solar installation company — not a tax advisory firm. Consult a qualified tax professional or CPA to determine how the ITC applies to your specific tax situation before making purchasing decisions based on anticipated tax benefits.
Production varies by roof orientation (south-facing is optimal), pitch, shading, and system size. Tesla's design process uses aerial imagery and 3D modeling to determine the optimal tile placement for your specific roof, taking into account every plane, every shadow, and every obstruction. The system is designed to maximize production on your actual roof — not a theoretical ideal.
Solar production estimates, utility cost offset projections, and savings figures on this page are illustrative approximations based on general Nashville climate data and average residential energy consumption. Actual energy production depends on system size, roof orientation, pitch, shading, weather patterns, tile degradation, equipment performance, and other factors. Actual utility cost offsets depend on energy production, consumption patterns, utility rate structures, net metering policies, and rate changes over time — all of which are variable and outside our control. Past performance of solar installations is not indicative of future results. No specific energy production, savings, or financial outcome is guaranteed.
We begin with a virtual or on-site consultation to assess your home, your energy goals, and whether Tesla Solar Roof is the right fit. We review your current electricity usage, your roof's condition and orientation, any structural considerations, and your budget. If Tesla Solar Roof is a match, we move to design. If another option makes more sense — traditional metal roofing, metal plus panels, or something else — we tell you that too.
Using aerial imagery and 3D modeling of your roof, Tesla creates a custom design that specifies the placement of every solar tile and steel tile, optimizing for energy production, aesthetics, and cost. You receive a detailed proposal showing the system size (kW), estimated annual production (kWh), tile layout, Powerwall configuration, and a firm price. This is not a generic estimate — it is a design specific to your roof.
Once you approve the design, we handle the permitting process with your local building department (Metro Nashville, Williamson County, etc.) and your utility company (Nashville Electric Service or your local provider). Permitting timelines vary — typically 2–6 weeks in the Nashville area, sometimes longer depending on municipal workload.
The existing roof is removed and the new Tesla Solar Roof and Powerwall are installed. Installation typically takes 5–7 business days depending on roof size, complexity, and weather. This is a full roof replacement — not an overlay. The old roof comes off completely, the deck is inspected and repaired as needed, underlayment is installed, and the Tesla tile system goes on from there.
Your local building authority inspects the completed installation to ensure it meets code. We coordinate the inspection scheduling and are on site to address any questions.
The final step is receiving approval from your utility company to activate the system and connect it to the grid. Once PTO is granted, the system is turned on — and your roof starts generating electricity. From that moment forward, every sunny day is reducing your electricity bill and charging your Powerwall for the nights and storms ahead.
Tesla Solar Roof is designed to be the most visually integrated residential solar option available. Traditional panels on a metal roof generally offer a lower total cost for comparable solar production. If you need a new roof and visual integration matters, Tesla Solar Roof is designed for that. If your existing roof is solid and you want to add solar production at a lower entry point, traditional panels are designed for that. We install both and can help you compare the options for your specific home.
The comparison above is a general overview for informational purposes. Product specifications, pricing, availability, and performance characteristics are subject to change. Specific comparisons should be based on formal proposals for your individual project. We are not endorsing one option over another — the appropriate choice depends on your specific circumstances, priorities, and budget.
Yes. The Metal Roofers is a Tesla Certified Installer for Solar Roof in the Nashville and Middle Tennessee area. This means we have been trained and approved by Tesla to design, install, and service Tesla Solar Roof systems. Tesla requires all installations to be performed by certified installers to maintain warranty coverage.
The physical installation typically takes 5–7 business days depending on roof size, complexity, and weather. The entire process from order to power-on — including design, permitting, installation, inspection, and utility approval — typically takes 2–4 months in the Nashville area. Permitting timelines are the most variable factor. Actual timelines vary by project and are not guaranteed.
A single Powerwall 3 provides 13.5 kWh of storage and 11.5 kW of continuous power — typically sufficient for essential loads (refrigerator, lights, Wi-Fi, phone charging, some outlets) for an estimated 24–48 hours depending on usage. For whole-home backup including air conditioning and heavy loads, multiple Powerwall units may be needed. Actual backup duration depends on household consumption, system configuration, weather, and battery condition.
No. The 30% federal ITC applies only to the solar-generating components: active solar tiles, the integrated inverter, Powerwall, and their associated installation labor. It does not apply to the non-solar steel tiles, roof tear-off, or general roofing work. We provide a detailed breakdown showing which line items may qualify. Tax credit eligibility depends on individual circumstances — consult a qualified tax professional for guidance specific to your situation.
Yes. Powerwall 3 supports expansion units — battery-only packs that add 13.5 kWh of storage capacity each. A single Powerwall 3 can support up to three expansion units, bringing total storage to 54 kWh. Expansion units add storage duration but not additional power output — if you need to run more heavy loads simultaneously, additional full Powerwall 3 units (each with their own inverter) may be required. Pricing and availability subject to change by Tesla.
Tesla Solar Roof carries a Class 4 hail rating — the highest available — meaning the tiles have been tested to withstand 2-inch hail impacts per industry testing standards. The tempered glass solar tiles and the steel roofing tiles are both engineered for all-weather protection. No roofing system is indestructible — extreme events beyond tested parameters may cause damage covered under warranty and/or homeowner's insurance.
Nashville's snow events are typically modest and short-lived. The dark, smooth glass surface of Tesla solar tiles helps snow melt and slide off faster than traditional roofing. Tesla's system also includes a pre-heat feature that can use a small amount of stored energy to warm the tiles and shed snow — restoring production as quickly as conditions allow. Annual snow impact on Nashville production is generally minimal, though actual production varies with weather.
If your metal roof is in good condition, adding traditional solar panels may be a more cost-effective path than removing the metal roof to install Tesla Solar Roof. A standing seam metal roof with clamp-mounted solar panels (no penetrations) provides a long-lasting roof plus solar production, often at lower total cost. We install both configurations and can help you compare options for your specific situation.
Industry research suggests that solar energy systems may positively affect home values, though the amount varies by market, system size, and local demand. Tesla Solar Roof's integrated design, appearance, and comprehensive warranty may be viewed favorably by buyers. The 25-year warranty is transferable to subsequent homeowners. We are not real estate appraisers — consult a local real estate professional for guidance on property valuation in your area.
