About
Ra is a high-efficiency solar panel solution developed by Spacemanic, designed for nanosatellites and other space platforms. It is built with premium solar cells and can be tailored to match a satellite’s structure and power profile, ensuring reliable and mission-optimized energy. The product is ITAR free and offers a wide range of customization options due to in-house developed hardware and software. Customization includes body-mounted or deployable configurations, structural panels without cells, cutouts, and integration of temperature sensors, sun-sensors, magnetorquers, patch antennas, bypass protection diodes, and specific mechanical and electrical interfaces. Each panel is designed to fit the satellite’s specifications, including custom features and cutouts. The product includes custom panels, a CAD model, one hour of engineering support, and shipping and packaging. Lead time ranges from 3 to 7 months, depending on solar cell availability. Ra offers high efficiency, with typical power harvest up to 1.2 W per cell, and configurations for 1U, 2U, 3U, 6U, and 8U satellites, as well as customized designs. It has flight heritage.
