Solar Shingles vs Solar Panels: Cost, Efficiency & Pros and Cons
Solar panels are the better choice for most homes. They cost less per watt, produce more electricity from the same roof area, and are easier to expand and service.
Solar shingles make the most sense when a new roof is already needed and appearance is a top priority. The decision also looks different in 2026: Tesla stopped selling its Solar Roof in August, and the 30% federal homeowner tax credit ended for systems installed after 2025.
With more than a decade of experience in solar design and engineering, we've seen how both technologies perform on real projects. Here's how they compare on cost, efficiency, durability, appearance, and permitting, plus which solar shingle brands are still available.
Solar Shingles vs Solar Panels at a Glance
Solar panels win on cost, power output, and flexibility. Solar shingles win on appearance and can double as a new roof. Here's a side-by-side comparison of the factors that matter most.
Factor | Solar Shingles | Solar Panels |
Appearance | Integrated into the roof surface | Mounted above the roof on racking |
Upfront cost | Higher | Lower |
Energy per usable roof area | Generally lower | Generally higher |
Roof replacement | Often installed as part of a new roof | Usually installed on an existing roof |
Installer availability | Limited, specialized contractors | Widely available |
System expansion | Difficult | Usually straightforward |
Replacing individual components | Often specialized | Generally simpler |
Roof attachments | Product-dependent | Racking and roof attachments required |
Permit and design documentation | May require product-specific roofing and BIPV details | More standardized |
Utility interconnection | Required for grid-tied systems | Required for grid-tied systems |
Battery compatibility | Yes | Yes |
Best fit | New or replacement roof where looks are a priority | Maximum production and value |
2026 federal homeowner tax credit | None under Section 25D | None under Section 25D |
What Are Solar Shingles?
Solar shingles are roofing products that generate electricity while protecting a home from the weather. Instead of mounting panels on top of the roof, the solar cells are built into the roofing material itself. They're a form of building-integrated photovoltaics (BIPV), meaning the solar technology is part of the building rather than added to it.
Some designs look almost identical to asphalt shingles. Others use glass, metal, or tile formats that sit lower and blend in better than rack-mounted panels.
How Do Solar Shingles Work?
Solar shingles and solar panels generate electricity the same way. Both use photovoltaic cells to convert sunlight into DC electricity, and an inverter converts that power into AC electricity for the home. Both work with grid-tied systems and home batteries.
The key difference is installation:
Solar panels mount on top of an existing roof using racking and roof attachments.
Solar shingles replace some or all of the roofing material.
Because shingles are the roof, installing them usually happens during a full or partial roof replacement.
Are Solar Shingles the Same as Solar Tiles?
Yes. Solar shingles and solar tiles are the same basic product, and the terms are often used interchangeably. The name usually reflects the roofing style they imitate: "shingles" for asphalt-style products and "tiles" for glass, slate, or clay-style products.
What Is the Difference Between a Solar Roof and Solar Panels?
A solar roof uses photovoltaic roofing materials that replace part or all of the conventional roof surface. Rooftop solar panels are different: they're mounted above an existing roof rather than serving as the roofing material. People sometimes use "solar roof" casually to mean any rooftop solar, so it's worth confirming which one a quote covers.
What Solar Shingles Are Not
Two similar-sounding products often get confused with solar shingles:
Shingled solar panels are conventional rack-mounted panels built with overlapping strips of solar cells, a design that increases power output. They're panels, not roofing.
Solar reflective (cool roof) shingles are regular asphalt shingles that reflect sunlight to reduce heat gain. They don't generate electricity.
Are Solar Shingles as Efficient as Solar Panels?
No, solar shingles generally produce less power from the same roof area than conventional panels. Rack-mounted panels deliver more rated power per square foot of usable roof, and they benefit from airflow beneath the array. Some roof-integrated products have less rear ventilation, which can reduce output at higher temperatures.
Premium residential solar panels commonly exceed 22% module efficiency. For example, the Qcells Q.TRON BLK M-G2+ series reaches up to 22.5%, and some high-efficiency models approach 24%.
Efficiency figures for solar shingles vary more because each product has a different size, shape, and exposed area. Older shingle products typically fell in the mid-teens. For example, SunTegra's specifications listed shingle efficiency between 15.9% and 17.2%.
Why Watts per Shingle Can't Be Compared to Watts per Panel
Don't compare watts per shingle with watts per panel. Compare watts per square foot, total system size in kilowatts, and expected annual production in kilowatt-hours. A shingle is much smaller than a panel, so its wattage rating alone says little about how much electricity the whole roof will produce.
For context, one 450-watt panel has the same rated output as about eight 57-watt GAF shingles or four to five 100-watt Luma shingles. Estimated annual kWh production is the fairest way to compare quotes.
How Much Do Solar Shingles Cost Compared With Solar Panels?
Solar shingles cost more than solar panels on a per-watt basis. The fairer comparison, however, is a solar roof versus a new roof plus solar panels, because shingles replace roofing material that would otherwise be paid for separately. If the roof has years of life left, panels are almost always cheaper.
For conventional panels, Berkeley Lab's U.S. Distributed Solar and Storage data shows a median installed price of about $4.00 per watt DC for host-owned residential systems installed in 2024, before incentives. Prices varied widely, with the middle 60% of projects ranging from roughly $3.00 to $5.20 per watt.
Solar shingle pricing is far less transparent. Manufacturers generally require project-specific quotes, so there's no reliable national benchmark. Costs vary based on roof size, roofing material, active solar area, roof complexity, electrical work, and local labor.
Why Cost per Watt Can Be Misleading
Cost per watt only measures the solar portion of a project. A solar shingle quote usually includes roofing, while a panel quote doesn't. Here's how the costs break down:
Cost Factor | Solar Panels | Solar Shingles |
Solar equipment and installation | Lower | Higher |
New roof required? | Usually no | Often part of the project |
Roofing included in quote | No | Typically yes |
Cost per watt | Lower | Higher |
Best economic fit | Roof in good condition | Roof already needs replacement |
Future roof replacement | Panels must be removed and reinstalled | Solar roof already serves as roofing |
What If the Roof Already Needs Replacement?
If the roof needs replacing within the next few years, compare two complete projects rather than two solar quotes. The solar roof may close much of the price gap once roofing costs that would be paid either way are included.
Compare these two options:
Option A: A new conventional roof plus a rack-mounted solar panel system.
Option B: An integrated solar roof that combines both.
Future costs matter too. Panels installed on an aging roof will likely need a solar panel removal and reinstallation when the roof wears out. These detach-and-reset projects typically run $1,500 to $6,000 or more depending on system size.
Manufacturers are also targeting this comparison directly. CertainTeed claims its new Landmark PWR system is the first building-integrated solar product priced competitively with a re-roof plus traditional panels. Get quotes for both options before assuming either is cheaper.

Do Solar Shingles Qualify for the Federal Tax Credit in 2026?
No. Homeowners installing solar shingles or solar panels in 2026 can't claim the former 30% Residential Clean Energy Credit under Section 25D. According to the IRS, the credit isn't available for expenditures made after December 31, 2025. State, utility, and local incentives may still apply.
State and local programs are searchable in the Database of State Incentives for Renewables & Efficiency (DSIRE). For background on the change, read our article on the solar tax credit ending.
Leases and power purchase agreements (PPAs) work differently. Homeowners who lease solar or sign a PPA generally don't claim a tax credit themselves because they don't own the system. The U.S. Department of Energy notes that tax benefits don't go to lease and PPA customers, and any incentives for the system owner fall under separate business tax rules.
Solar Shingle Brands Available in 2026
The solar shingle market has narrowed. Tesla and SunTegra have exited, and the remaining options come mostly from established roofing manufacturers. Here are the main solar shingle products still sold in the United States.
GAF Timberline Solar ES 2
GAF Timberline Solar is one of the most prominent solar shingle systems still available. It's made by GAF Energy, the solar business of GAF, and designed for asphalt shingle roofs.
The ES 2 shingle produces 57 watts, up 23% from the previous 46-watt version. It installs with a standard nail gun, with no mounting racks or bracket penetrations, and sits less than a quarter inch above the roof deck. The solar shingles install alongside GAF's Timberline asphalt shingles on the rest of the roof.
GAF offers a 25-year warranty against manufacturer defects that cause leaks, a 15-year wind warranty, a 25-year power output warranty, and a 130-mph wind rating. Only ES 2 packages carrying the UL 2218 listing statement are rated for Class 4 impact resistance. Learn more on the GAF Timberline Solar product page.
Best fit: Asphalt shingle roofs that need replacement. GAF itself recommends considering the system when planning a new roof.
CertainTeed Solstice Shingle, Landmark PWR, and SunStyle
CertainTeed offers the widest range of integrated solar roofing products, spanning asphalt-style solar shingles and premium solar tiles.
The Solstice Shingle reaches 70 watts using full-size solar cells. It carries a 25-year limited power output warranty, a 25-year limited workmanship warranty, and a 10-year, 110-mph limited wind warranty.
Landmark PWR, CertainTeed's newest product, uses half-cut cells in 4-foot shingles that produce 85 watts each. It becomes available November 1, 2026. For a tile look, CertainTeed sells Swiss-made SunStyle solar tiles through a partnership announced in 2024.
Best fit: Projects that need style options and one manufacturer backing both the roof and the solar components. CertainTeed's older Apollo II system has been replaced by these products.
Luma Solar
Luma Solar makes a premium solar roofing system built around metal shingles, suited to homes that want a metal roof and prioritize durability.
Lumalvalume steel shingle. The system requires only one roof-deck penetration for wiring, and Luma describes the shingles as upgradeable.
Solar shingles blend with non-solar metal shingles, so only the sunniest roof areas need to carry solar. Luma currently markets its system in the U.S., but availability and project lead times should be confirmed directly with Luma or a certified installer.
Best fit: Metal roofs on projects with a flexible budget.
Solar Shingle Products No Longer Available
Several well-known solar shingle products have exited the market. Older reviews and comparison articles may still list them.
Tesla Solar Roof: Discontinued for new orders in August 2026. See the next section for details.
SunTegra: The company says it is shutting down due to financial distress from U.S. tariffs and asks existing customers to contact it about product support. Solar Power World covered the challenges that led to the closure.
CertainTeed Apollo II: Replaced by CertainTeed's Solstice Shingle, Landmark PWR, and SunStyle products.
Dow Powerhouse: Dow's solar shingle business closed years ago, and SunTegra's founder bought its shingle equipment as it was closing down.
What Happened to the Tesla Solar Roof?
Tesla discontinued new Solar Roof sales in August 2026. New Tesla Solar Roofs can no longer be ordered, but existing systems remain covered by their warranties. Tesla continues to sell conventional solar panels and Powerwall batteries, and its Solar Roof web page now redirects to its solar panel page.
Tesla stopped accepting Solar Roof orders on August 20, 2026. The product never reached scale: Tesla installed only about 3,000 Solar Roof systems in the U.S. over roughly seven years, far short of Elon Musk's promise of 1,000 installations per week.
It was positioned as a luxury product, and some homeowners reported quotes as high as $200,000. TechCrunch's analysis and Electrek's reporting on installer losses cover the full story.
Can Existing Tesla Solar Roof Systems Still Be Repaired?
Yes. Discontinuing the product doesn't cancel coverage for systems already installed, and Tesla's Solar Roof Limited Warranty transfers to future owners of the home.
Owners should contact Tesla or a Tesla Certified Installer first. The warranty excludes damage caused when anyone else installs, removes, reinstalls, or repairs the Solar Roof. Long-term availability of replacement tiles is less certain, according to contractors interviewed by Roofing Contractor.
What Are the Best Tesla Solar Roof Alternatives?
The main alternatives are other integrated solar roofs or conventional panels. GAF Timberline Solar and CertainTeed's Solstice and Landmark PWR systems suit asphalt-style roofs. SunStyle and Luma offer premium tile and metal looks. For the lowest cost, a new roof plus conventional panels remains the most common choice.
Solar Shingles Pros and Cons
Solar shingles offer a cleaner look and combine two projects in one, but they cost more and produce less power per square foot than panels.
✅ Pros of Solar Shingles
Curb appeal: They blend into the roof, which matters on homes where mounted panels are considered unsightly.
Two projects in one: A new roof and a solar system are completed in a single installation.
No future detach-and-reset: There's no need to remove and reinstall panels when the roof needs replacing.
Fewer rack attachments: Many products avoid the racking and roof penetrations that panels require.
Durability: Leading products carry long leak, wind, and power warranties.
❌ Cons of Solar Shingles
Higher upfront cost: Especially when the current roof has years of life left.
Lower power density: More roof area may be needed to match the output of a smaller panel system.
Limited installers: Fewer contractors are certified, which can mean longer waits and higher labor costs.
Harder to expand: Adding capacity later is more complex than adding another panel.
More permitting detail: Plan sets may need product-specific roofing and BIPV documentation.
Market risk: Several solar shingle manufacturers have exited, which can affect long-term parts and support.
Solar Panels Pros and Cons
Solar panels deliver the most electricity for the money, but they sit visibly on the roof and depend on the roof beneath them.
✅ Pros of Solar Panels
Lower cost per watt: Panels are mass-produced, which keeps prices down.
Higher output: They generate more power per square foot of roof.
Wide installer choice: Most solar companies install panels, so quotes are easier to compare.
Easy to expand and service: Panels can be added or a single module replaced without touching the roof.
Proven track record: Most panels carry 25-year performance warranties. Learn more in our guide to solar panel warranties.
❌ Cons of Solar Panels
Visible on the roof: Some homeowners and HOAs object to the look.
Roof penetrations: Racking requires attachments, which must be properly flashed to prevent leaks.
Tied to roof lifespan: If the roof wears out first, the panels must be removed and reinstalled. Choosing the best roof for solar panels helps avoid this.
How Are Solar Shingles Designed and Permitted?
Solar shingles go through the same building, electrical, and utility approval process as conventional rooftop solar. The permit package often needs more product-specific detail, however. Because the solar system is also the roof covering, designers may need to document both the roofing assembly and the photovoltaic system, including listings, fire classification, wind ratings, and manufacturer installation requirements.
What Code Requirements Apply to Solar Shingles?
Solar shingles must meet roofing code requirements and electrical code requirements at the same time. Under the International Residential Code, they must be listed to a building-integrated photovoltaic (BIPV) standard, installed per the manufacturer's instructions, and meet wind classification requirements. The electrical system must comply with NEC Article 690.
Under the 2024 IRC, BIPV shingles must be listed and labeled to UL 7103, attached per the manufacturer's installation instructions, and meet the wind classification table for the site's design wind speed. UL 7103 combines electrical, mechanical, weathering, wind, impact, and fire testing for BIPV roof coverings. The product's wiring is also evaluated against NEC Article 690.
Fire classification is part of the review as well. The 2021 IRC requires rooftop BIPV products to carry a fire classification tested to UL 7103. A Class A, B, or C assembly is required where the AHJ designates one or where the roof edge sits within 3 feet of a lot line.
Section numbers vary by code edition, and some states amend them. Florida's 8th Edition Building Code, for example, adds its own wind resistance testing requirements for BIPV roofing modules. Always check which code edition and local amendments the AHJ has adopted.
Are Solar Shingles Harder to Permit Than Solar Panels?
They can be. Both systems require building and electrical review, but solar shingles may need additional product-specific roofing, fire classification, wind rating, or installation documentation because the solar system is integrated into the roof. Some AHJs are also less familiar with BIPV products, which can lead to more reviewer questions. Requirements depend on the product and jurisdiction.
Trade responsibilities can add another layer. Because BIPV products serve as both roofing and electrical equipment, questions about which trade should install and maintain them can arise. Some jurisdictions may require roofing and electrical scopes to be permitted or inspected separately.
What Should Solar Installers Know Before Quoting Solar Shingles?
Before quoting a solar shingle project, confirm the product's code listings, the AHJ's adopted code edition, and the utility's interconnection requirements. Also confirm who holds the roofing and electrical scopes. Gathering manufacturer documentation early helps avoid plan review corrections and resubmittals.
A complete solar shingle plan set typically includes:
Product documentation: UL 7103 listing, fire classification, wind rating, and manufacturer installation instructions.
Roof layout: Active solar areas, non-solar roofing areas, and transitions between them.
Electrical design: Single-line diagram, conductor routing, inverter and equipment specifications, and rapid shutdown compliance under NEC 690.12.
Structural information: Any roof framing documentation the AHJ requires.
Code references: The code edition and local amendments the design is based on.
Do Solar Shingle Systems Need Utility Interconnection?
Yes. Grid-tied solar shingle systems require utility interconnection approval before they can operate, just like rack-mounted solar. The application typically includes system size, inverter and equipment details, a single-line diagram, and the utility's required agreements. Approval timelines and requirements vary by utility.
For solar contractors, accurate documentation keeps projects moving through review. GreenLancer's U.S.-based team and nationwide network of licensed professionals deliver permit-ready solar plan sets and PE-stamped solar engineering for residential rooftop PV projects. Our in-house team also handles residential interconnection applications.
Are Solar Shingles Worth It?
Solar shingles can be worth it when a new roof is already needed and appearance is a high priority. Conventional solar panels are usually the better choice when maximizing energy production and minimizing cost are the priorities. The condition of the current roof is often the deciding factor.
Solar Shingles May Make Sense If:
The roof needs replacement within the next few years.
Curb appeal is a major priority.
The roof has enough sunny, unshaded area to meet energy goals.
A smaller pool of installers and products is acceptable.
The comparison is a solar roof against a new roof plus panels, not panels alone.
Solar Panels May Make More Sense If:
The existing roof has plenty of service life left.
Roof area is limited and maximum output is needed.
The lowest cost per watt is the priority.
The system may be expanded later.
Broad choice in installers and equipment matters.
In HOA communities, check state rules before assuming panels aren't allowed. The Department of Energy notes that many states have solar access laws that stop HOAs from prohibiting or unreasonably restricting solar. See the DOE Homeowner's Guide to Solar for details.
Solar Shingle and Rooftop PV Design Support
Solar shingles and conventional panels both depend on accurate electrical design, code-compliant documentation, and jurisdiction-specific permitting. A plan set that anticipates AHJ questions helps projects avoid corrections, resubmittals, and delays.

Solar Shingles vs Solar Panels FAQs
Are solar shingles better than solar panels?
Solar panels are better for most projects because they cost less and produce more power per square foot. Solar shingles are better when a new roof is needed and the goal is solar that blends into the roofline. The right choice depends on roof condition, budget, and how much appearance matters.
Are solar shingles more expensive than solar panels?
Yes, solar shingles cost more per watt than conventional panels. However, a solar shingle project usually includes roofing, so the price gap narrows when compared against a new roof plus a panel system. If the current roof is in good condition, panels are almost always less expensive.
Do solar shingles qualify for a federal tax credit in 2026?
No. The 30% Residential Clean Energy Credit under Section 25D ended for expenditures made after December 31, 2025, and that applies to both solar shingles and panels. State, utility, and local incentives may still be available. Homeowners who lease solar or sign a PPA don't receive tax benefits because they don't own the system.
Can you still buy a Tesla Solar Roof?
No. Tesla stopped accepting new Solar Roof orders on August 20, 2026, and now sells conventional solar panels and Powerwall batteries. Existing Solar Roof systems remain covered by Tesla's warranty, which transfers to future homeowners. Repairs should go through Tesla or a Tesla Certified Installer to avoid warranty issues.
How long do solar shingles last?
Leading solar shingles carry 25-year power output warranties, similar to conventional panels, and many include long leak and wind warranties on the roofing portion. Actual lifespan depends on the product, installation quality, and climate. By comparison, most conventional solar panels last 25 to 30 years.
Can solar shingles work with a home battery?
Yes. Solar shingles produce the same kind of electricity as solar panels, so they can connect to a home battery through a compatible inverter. A battery stores daytime solar power for use at night or during outages. Manufacturers typically specify which battery and inverter brands are approved for their systems.
Do solar shingles need a permit?
Yes. Solar shingles generally require building and electrical permits, and grid-tied systems also require utility interconnection approval. Because the solar modules are part of the roof, some AHJs request product-specific roofing details, electrical diagrams, equipment listings, fire ratings, or manufacturer installation instructions. Requirements vary by city, county, utility, and product.
