    • PRODUCT AND TECH

    OS1 Energy Pavilion

    OS1 combines a prefabricated backyard pavilion, overhead photovoltaic panels, and concealed battery storage beneath a finished deck. It provides outdoor living space while generating and storing electricity for the home.

    Solar Pavilion

    The Solar Pavilion uses six or twelve photovoltaic modules to deliver approximately 2.4–5.3 kW of generation. Concealed DC wiring routes power to an electrical wall for conversion and distribution.

    Horizon BladePack

    Horizon BladePack is a modular, low-profile lithium-iron-phosphate battery system installed horizontally beneath the deck. It supports 15–60 kWh of storage and can expand to as many as eight modules.

    Prefabricated Construction

    OS1 uses an architectural-grade aluminum frame, precision-machined components, GroundLock anchors, and SnapLock or precision-fit decking. These systems are designed to reduce excavation, concrete footings, and on-site construction complexity.
