Solar panels are modules that are mounted above an existing roof structure using racking systems. In contrast, solar roof tiles (or building-integrated photovoltaic systems) replace or integrate directly with the roof structure itself—the photovoltaic cells are built into or laminated onto the roofing tiles. Because solar roof tiles serve dual functions (roofing + generation), they typically reduce visual clutter, limit penetrations, and can be more seamless in appearance. The choice depends on whether a new roof is needed, architectural priorities, and site-specific shading and orientation conditions.
Solar roof tiles (also called photovoltaic roof tiles or solar shingles) integrate photovoltaic (PV) cells into roofing materials so the tiles themselves generate electricity while acting as the weatherproof roof surface. Rather than mounting panels above traditional roofing, the PV elements are built into or placed beneath the roofing material, creating a seamless, low-profile appearance.
How they work (mechanically & electrically):
• Each tile contains PV cells (often crystalline silicon) that convert sunlight (photons) into direct current (DC) electricity via the photovoltaic effect.
• Tiles are wired together (typically in series strings or sub-strings) so the voltages stack, then connected to a DC-to-AC inverter (or in some systems, hybrid inverters) that converts the DC into alternating current (AC) usable by household loads or for grid export.
• Excess electricity can be fed back to the grid (net metering) or stored in batteries.
• The roof structure underneath must support the tiles and often includes standard roofing underlayment, flashing, drainage, and electrical junctions.
Because solar roof tiles replace or act as the roof’s outer surface, they must meet both roofing and PV performance standards (weather sealing, wind uplift resistance, fire rating, impact resistance, etc.).
In short: solar roof tiles combine the functions of a roof and a solar generator into one integrated system, rather than layering panels on top of a roof.
ICON’s hurricane-zone performance is enabled by:
• Interlocking concrete tile design that resists uplift forces,
• System-level wind uplift testing up to 180 mph,
• Strong attachment and flashing systems that integrate with roofing structure,
• Full roof coverage eliminating weak points, and
• Compliance with codes for coastal and wind-borne debris zones.
These features help ensure that ICON roofs maintain structural integrity and solar functionality even in high-wind hurricane conditions.
ICON uses a double batten installation system that creates ventilation under the tiles while securing them with stainless steel fasteners. The interlocking concrete tiles have been tested to resist wind uplift exceeding 130+ mph, in compliance with ASTM D3161 and TAS 125.
ICON is engineered with structural robustness suitable for full-roof installation. The system uses a concrete substrate (similar to flat-slate-style concrete tile) combined with encapsulated solar cells. Its design is tested for wind uplift (up to 180 mph), fire resistance (Class A rating), and impact resistance. ICON tiles have been tested under UL 2218 Class 3 or higher impact ratings, meaning they can withstand hail impacts up to 1.75 inches and flying debris typically encountered during hurricanes.
The integrated roofing material is built to last decades under normal environmental stress, and the photovoltaic portion is backed by performance warranties (e.g. 25 years typical in the industry). Because the tile and solar are unified, there are fewer interfaces or separations that can degrade over time.
Because ICON uses a noncombustible concrete substrate, the roofing material itself resists ignition from embers or wildfire conditions. The solar cells are fully integrated within the tile, with minimal exposed wiring or components that could catch stray embers or sparks. This design reduces the risk of fire propagation from solar parts. In regions at high wildfire risk, this kind of all-in-one, robust roofing system can be safer than external-mounted solar panels.
ICON is built as part of the roof structure, not as an add-on. The solar cells are embedded flush within the concrete tiles. The electrical connections are routed internally, and no visible racks, rails, or mounting hardware are required on the exterior. As a result, the roof surface presents a uniform tile appearance with integrated solar function rather than panels mounted above.
Yes. ICON is certified under UL 61730, which is the current safety standard for photovoltaic (PV) modules, replacing the older UL 1703 standard UL Solutions+1.(https://www.ul.com/news/ul1703-ul-61730-pv-module-safety-standards-updates-making-transition?utm_source=chatgpt.com) This certification addresses safety in construction, fire, electrical insulation, and mechanical strength.
ICON holds several certifications and ratings, including:
• UL 61730 (PV safety standard)
• IEC 61215 (performance under environmental stress)
• Class A fire rating (ASTM E108 / UL 790)
• Wind resistance testing up to 180 mph
• Compliance with electrical connection standards (MC4 compatibility)
• Appropriateness for coastal hurricane zones
These certifications validate safety, durability, and performance under industry and code requirements.
