3U Solar Panel

EnduroSat's 3U Solar Panels utilize seven highly efficient triple junction solar cells. The variant 3U Deployable Solar Array utilizes fourteen highly efficient triple junction solar cells arranged into 1 fixed + 1 deployable panels. The deployable solar array doubles the energy generation capability of your satellite. 

The 3U Solar Panels support multiple integrated sensors and it are fully compliant with the CubeSat standard. The high power generation capabilities, radiation and temperature resilience ensure smooth space operations.
