The 3U Solar Panel is a lightweight, body-mounted CubeSat solar panel purpose-built for 3U nanosatellites. Seven space-grade triple-junction photovoltaic cells deliver a peak power of 8.4 W in LEO, with cell efficiency above 30% at beginning of life and better than 29% at end of life – radiation-resistant performance designed to last a five-year mission. Weighing only 147 g, the panel is one of the lightest paths to dependable satellite solar power in the 3U form factor, and internal bypass diodes protect each cell against reverse bias.

More than a power source, the panel carries onboard sensing: temperature and sun sensors are integrated, a gyroscope is optional, and up to three photodiodes provide coarse sun-vector data for attitude support and power optimization. An accessible remove-before-flight (RBF) inhibition mechanism streamlines integration and ground handling. Multiple panels connect in parallel for custom power configurations, and options including an external magnetorquer connector, a low-power MCU, additional photodiodes, and a temperature sensor allow each space-qualified unit to be tailored to the mission's electrical power system. Each delivery includes a complete user manual and an hour of engineering support.
