Solar tile roofs combine cutting-edge renewable energy technology with aesthetic roofing design, offering an innovative solution for homeowners seeking sustainability without sacrificing style. Unlike traditional solar panels that sit on top of your roof, solar tiles integrate seamlessly into the roofing system, doubling as both roof protection and energy generators. In this comprehensive guide, we’ll explain what solar tile roofs are, how they work, their advantages and disadvantages, installation details, costs, and whether they’re the right choice for your home. You can always use our website to find solar installers near you.
What Are Solar Tile Roofs?
Solar tile roofs, also called solar shingles or building-integrated photovoltaics (BIPV), are roofing materials embedded with photovoltaic (PV) cells. These tiles resemble traditional roofing materials—such as asphalt, slate, or clay—but they generate electricity by absorbing sunlight. By blending into your roofline, solar tiles provide a sleek, low-profile alternative to bulky rooftop solar panels.
How Solar Tiles Work
Each solar tile contains photovoltaic cells that convert sunlight into electrical energy. This electricity is routed through an inverter to power your home or stored in batteries for later use. Excess energy can be fed back to the grid through net metering programs, potentially reducing your utility bills further or even earning you energy credits.
Types of Solar Roofing Tiles
1. Tesla Solar Roof
Tesla’s solar roof uses tempered glass tiles integrated with solar cells, famed for its sleek appearance and seamless integration with Tesla Powerwall battery storage. Tesla claims their tiles are three times stronger than standard roofing materials and can last over 30 years.
2. CertainTeed Apollo II
Designed to work with traditional asphalt shingles, Apollo II solar shingles provide an easier retrofit option. They offer high efficiency and durability from a trusted roofing manufacturer.
3. Luma Solar Roof
Luma solar shingles are known for modular design, allowing for easy replacement and upgrades over time without tearing off the entire roof.
4. SunTegra Solar Roof Systems
SunTegra offers solar shingles installed directly onto the roof decking, reducing labor and installation time, ideal for homes with newer roofs.
Benefits of Solar Tile Roofs
1. Aesthetics
Solar tiles blend naturally into your roofline, unlike bulky panels that can disrupt your home’s curb appeal. A 2023 survey found 68% of homeowners cite appearance as a key factor when choosing solar solutions.
2. Energy Efficiency
According to the National Renewable Energy Laboratory, solar tiles can generate enough energy to cover 20-40% of a typical household’s electricity needs, varying by location and roof size.
3. Increased Home Value
Studies show homes with solar installations can sell for up to 4.1% more than comparable homes without solar.
4. Durability
Tesla solar tiles are rated to withstand hail up to 1.75 inches in diameter, wind speeds of up to 165 mph, and fire resistance.
5. Tax Incentives
The federal solar Investment Tax Credit (ITC) currently offers a 30% credit on the total installation cost through 2032, with additional state and local incentives available.
Drawbacks to Consider
1. High Initial Cost
Installation can range from $30,000 to $80,000 or more. By comparison, traditional solar panel systems cost about $15,000 to $25,000 on average.
2. Complex Installation
Fewer contractors are qualified to install solar tiles, leading to longer project timelines and limited availability in some areas.
3. Lower Efficiency Than Panels
Solar tiles tend to produce about 10-15% less electricity per square foot than traditional solar panels, meaning you may need more roof coverage to meet your energy goals.
4. Limited Availability
Because the technology is emerging, some regions have limited access to products and certified installers.

Cost Breakdown
Solar Tile Roof Costs
- Materials: $20 to $35 per square foot
- Installation: $8 to $15 per square foot
- Total Installed Cost: $30,000 to $80,000 for an average home
Traditional Solar Panels (For Comparison)
- Total Installed Cost: $15,000 to $25,000
- Panel Efficiency: 17 to 22 percent
- Roof Coverage: Only part of the roof
Installation Process
Step 1: Roof Evaluation
A professional will assess the pitch, sun exposure, and condition of your current roof to determine if solar tiles are a good fit.
Step 2: Custom Design
The contractor designs a roof system tailored to your energy needs, aesthetics, and roof layout.
Step 3: Removal and Preparation
If re-roofing, the old material is removed. The decking is inspected and prepped for new underlayment and tile installation.
Step 4: Installation of Solar and Non-Solar Tiles
Solar and dummy tiles are installed together to create a cohesive look. Inverters, wiring, and possibly battery systems are added.
Step 5: Activation and Inspection
After final inspections and utility approvals, the system is activated. You can start generating clean power immediately.
