Thermal Design Considerations

Roof-integrated solar systems experience elevated operating temperatures in warm climates. Installation geometry — including rear air space and ventilation — plays a meaningful role in how effectively heat is dissipated. Systems installed directly to the roof deck may operate at higher sustained temperatures than ventilated assemblies.

Technology

  • The Icon by VOLTAIC integrated solar roof tile is engineered as a real roofing system first, with solar built directly into the roof structure itself.

    ​

    Designed to preserve architectural continuity, Icon integrates solar only where energy production is needed, while the remainder of the roof uses matching, high-quality roofing materials for a cohesive appearance.

    ​

    Built to meet demanding building standards for wind, fire, and long-term durability, Icon installs using familiar roofing practices—reducing complexity without sacrificing performance.

    ​

    The result is an integrated solar roof that protects the home, performs reliably, and belongs architecturally.
