Solfit, a UK-based manufacturer of integrated solar solutions, has launched the JT 425Wp In-Roof Panel, setting a new benchmark for compliant, high-output solar technology for domestic rooftops.
Designed for UK housebuilders, developers and solar installers, the JT 425 combines enhanced performance, advanced safety features and rapid installation. It meets strict UK fire safety and building regulations, including full certification to B Roof (t4) fire resistance standards – now a critical compliance requirement for all in-roof solar systems on new homes.
With a 425-watt peak output, the panel delivers higher energy generation per module, reducing the total number of panels needed while helping housing developers meet Part L energy efficiency regulations. Constructed using double glass laminate, the design improves fire resistance, extends service life and removes the need for plastic or composite materials.
Installation has been engineered for speed and simplicity. The panel features Solfit’s patented interlocking metal frame, providing a secure, watertight fit with just 14 component parts – compared to over 70 in many competing systems – cutting labour time and complexity. Its landscape orientation also gives installers greater layout flexibility for various roof types and designs.
