About the offering
ClearPower: An Electricity-Generating Window Insert Problem Buildings consume 40% of global energy, and must drastically reduce emissions to combat climate change. Yet high-rise buildings with limited roof space have no viable option for generating their own clean electricity. Existing "solar windows" are either opaque (blocking views and natural light) or achieve only 2-3% efficiency - too weak to justify their cost. This leaves building owners facing mandatory decarbonization deadlines with no real solutions for their facades - the largest untapped surface area for energy generation. Sources: https://ec.europa.eu/commission/presscorner/detail/en/ip_24_1965, https://www.bcg.com/publications/2025/economic-growth-opportunities-greening-world Solution Stellaris windows achieve what physics said was impossible: 150 watts per square meter while maintaining full transparency. Our patented design uses narrow silicon cells arranged like micro venetian blinds - capturing sunlight without blocking your view. The National Renewable Energy Laboratory (NREL) validated that our solar panel window performance matches conventional solar panels. Market Around the country, laws are being passed requiring buildings to drastically reduce greenhouse gas emissions by eliminating fossil fuels. Energy codes are prohibiting new natural gas hook-ups and mandating renewable energy integration. The global building-integrated photovoltaics market is exploding from $23.67B in 2023 to $89.8B by 2030 - growing at 21.2% annually. The US market alone is surging at 22.1% yearly, driven by these mandatory decarbonization laws.

We've completed our automated manufacturing setup, received government validation of our performance claims, and won industry recognition including Architectural Record's Product of the Year. The Product Unlike competitors who embed experimental materials achieving just 2-3% efficiency, Stellaris uses proven bifacial silicon cells with 20+ year lifespans. Our patent-protected technology (5 issued, 1 pending) isn't integrated into the glass itself - it's an insert built into multi-pane windows. This insert design works with any window manufacturer - no custom glass fabrication or special sizes required. While others chase unproven technologies, we deliver performance matching conventional solar panels using industry-standard components that adapt to virtually any window size. By leveraging the window's existing encapsulation, we eliminate the costs of frames, backing sheets, and adhesives needed by conventional solar panels. This makes Stellaris windows cost-competitive while delivering superior performance. What's Ahead, Our Roadmap With manufacturing operational and first sales underway, Stellaris is focused on rapid market penetration. We're expanding partnerships with major glass manufacturers to establish nationwide distribution, pursuing building code certifications to streamline adoption, and scaling production capacity to meet growing demand. Use of funds Investment funds will be strategically allocated to capture the exploding BIPV market. Manufacturing scale-up takes priority (30%) to meet demand from glass partners, followed by sales expansion (25%) to drive nationwide adoption. Own a Piece of the Solar Breakthrough
