Energy born at home.
Solastra Energy develops solar window technology for buildings across Québec. Every pane generates clean electricity, feeds the grid, and connects to a network that grows more powerful with each installation.
Fits standard double and triple-glazed IGU frames. No custom construction, no structural changes — the same installation as any premium window.
"Light" variant (70% transmittance) for living spaces. "Power" variant (30%) for south-facing commercial facades. A tiered product line, not a single compromise.
Thin-film PV encapsulated to premium IGU standards. Designed to outlast the buildings it powers, with a U-value comparable to high-performance glazing.
Every Solastra window installed connects to a cloud-based energy management platform that tracks generation in real time, reports carbon impact, and aggregates installed capacity across buildings. The window is how we enter a building. The platform is how we stay.
"Not a window company. A clean energy infrastructure platform that uses solar windows as its customer acquisition engine."
Solastra was founded on a simple belief: that the buildings we inhabit should give back to the land they stand on. Every window we install is a small act of restoration. Our mission is to make clean energy generation a native feature of the built environment in Québec, manufactured here, monitored here, and owned here. Energy sovereignty is not a slogan. It is the architecture of what we are building.
We are actively seeking fabrication partners, building owners for our Montréal pilot, and research collaborators. Early partners shape the network.
