The roof that powers the building.
The Energy Roof isn't solar bolted onto a finished roof — it is the roof. One factory-built plane delivers three functions: weatherproofing, solar electricity, and heat-recovery ventilation.

FACTORY-PANELIZED INTERLOCKING TILES
It replaces the roof, not sits on it
Flush glass-and-silicone weatherproof surface with no exposed metal. You substitute a membrane you had to build anyway — and get energy for the delta cost.
Factory-built, panelized
Pre-engineered 4'×4' interconnecting panels attach to a prepared deck — made for panelized and modular construction workflows.
Actively thermal-managed
An intelligent under-panel air plenum cools cells in summer (recovering lost output) and delivers free solar-heated air in winter.
H O W I T W O R K S
Three functions.
One 4'×4' panel.
Glass-on-glass PV generates electricity while a 3-inch air plenum beneath the panels — tuned through CFD-validated thermal engineering — moves air with smart fans and dampers. Summer: cool the cells, shed heat, protect the interior. Winter: capture sun-warmed air as free space heating.
SUMMER: plenum air cools cells → +20–30% recovered output, lower cooling load
WINTER: sun-warmed plenum air ducted indoors → free pre-heated ventilation
ALWAYS: flush, weatherproof glass-and-silicone roof skin
