Problem
Homeowners and small communities often cannot install traditional rooftop solar panels due to roof orientation, structural limitations, or aesthetic concerns, limiting access to on‑site renewable electricity.
Solution
Exergi offers the Sunrise system, a residential concentrated solar power (R‑CSP) generator that fits in a backyard and uses a compact steam micro‑turbine to convert concentrated sunlight into electricity. By eliminating the need for roof installations, the system provides higher thermal‑to‑electric efficiency than conventional photovoltaic panels while maintaining a relatively low capital cost. The unit is designed for easy, plug‑and‑play installation, allowing users to generate clean power on‑site and reduce reliance on the grid. Energy output is managed through standard inverter interfaces, enabling seamless integration with existing home electrical systems.
Target Audience
Primary customers are residential homeowners and small community associations seeking a high‑efficiency, roof‑free solar solution for on‑site electricity generation.
