What are solar roof tiles and how much do they cost? Find out!
Solar roof tiles represent a revolutionary approach to home energy generation, seamlessly blending renewable energy technology with traditional roofing materials. Unlike bulky solar panels, these innovative photovoltaic tiles integrate directly into your roof structure, maintaining your home's aesthetic appeal whilst generating clean electricity. As homeowners increasingly seek sustainable energy solutions, understanding the technology, costs, and options available becomes essential for making informed decisions about this cutting-edge roofing solution.
Understanding Photovoltaic Tiles Technology
Photovoltaic tiles function similarly to traditional solar panels but are designed to replace conventional roofing materials entirely. These tiles contain photovoltaic cells that convert sunlight into electricity, typically producing between 13-20 watts per tile depending on the manufacturer and model. The tiles are interconnected through a wiring system beneath the roof surface, channeling generated power to an inverter that converts direct current into alternating current for household use.
The technology has advanced significantly in recent years, with modern photovoltaic tiles offering improved efficiency rates and enhanced durability. Most systems include smart monitoring capabilities, allowing homeowners to track energy production through smartphone applications. The tiles are designed to withstand harsh weather conditions, including hail, strong winds, and extreme temperatures, often exceeding the durability standards of traditional roofing materials.
Tesla Solar Shingles and Market Leaders
Tesla Solar Shingles have garnered considerable attention as one of the most prominent photovoltaic tile solutions available. Tesla’s Solar Roof system features glass tiles that closely resemble traditional slate, clay, or asphalt shingles whilst incorporating solar technology. The company offers both solar and non-solar tiles, allowing for strategic placement across the roof surface to optimise energy generation and maintain visual consistency.
Other notable manufacturers in the photovoltaic tiles market include SunTegra, GAF Energy, and CertainTeed. Each offers unique designs and specifications, with varying efficiency rates and aesthetic options. SunTegra focuses on tiles that integrate with existing roofing materials, whilst GAF Energy’s Timberline Solar system embeds photovoltaic technology within traditional-looking shingles. These alternatives often provide more immediate availability compared to Tesla’s system, which has historically faced production delays.
Installation Considerations and Requirements
Installing photovoltaic tiles requires specialised expertise, as the process involves both roofing and electrical work. The installation typically begins with removing existing roofing materials and potentially upgrading the roof deck to accommodate the new system. Professional installers must ensure proper waterproofing, electrical connections, and integration with the home’s power system.
The installation process generally takes several days to weeks, depending on roof size and complexity. Homeowners should verify that their roof structure can support the additional weight of photovoltaic tiles, which may be heavier than traditional materials. Local planning permissions and building regulations compliance are essential considerations, particularly for listed buildings or properties within conservation areas.
Photovoltaic Tile Prices and Cost Analysis
How much do photovoltaic tiles cost varies significantly based on system size, manufacturer, and installation complexity. Current market prices typically range from £400-£800 per square metre for the tiles themselves, with installation costs adding substantially to the overall investment. A complete system for an average UK home might cost between £30,000-£60,000, considerably more than traditional solar panel installations.
The higher initial cost reflects the integrated nature of photovoltaic tiles, which serve dual purposes as both roofing material and energy generation system. When comparing costs, homeowners should consider the value of replacing an existing roof alongside adding solar capability, as this dual functionality can justify the premium over separate roofing and solar panel projects.

Photovoltaic Tiles 2025 Market Outlook
The photovoltaic tiles market continues evolving rapidly, with 2025 expected to bring increased availability and potentially improved pricing as manufacturing scales up. Industry analysts predict enhanced efficiency rates and reduced costs as competition intensifies among manufacturers. Government incentives and net metering programmes may further improve the financial attractiveness of photovoltaic tile installations.
Technological advances anticipated include improved tile efficiency, enhanced monitoring systems, and better integration with home energy storage solutions. Battery storage compatibility is becoming increasingly important, allowing homeowners to store excess energy for evening use or power outages. These developments position photovoltaic tiles as an increasingly viable option for environmentally conscious homeowners seeking comprehensive energy solutions.
Solar roof tiles represent a sophisticated approach to renewable energy adoption, offering aesthetic integration that traditional solar panels cannot match. Whilst the initial investment remains substantial, the technology provides long-term energy generation benefits alongside roofing replacement value. As manufacturing capabilities expand and costs potentially decrease, photovoltaic tiles may become increasingly accessible to UK homeowners seeking sustainable energy solutions without compromising their property’s visual appeal.
