Solar Panels

Ananth Technologies designs and manufactures high-performance solar panels for satellites ranging from CubeSats to advanced microsatellites. Developed at their Bengaluru space hardware facility, these solar panels combine flight-proven materials, precision engineering, and comprehensive environmental testing to deliver reliable power generation in demanding orbital conditions. Key features include high-efficiency triple-junction solar cells (GaInP/GaInAs/Ge) from leading international suppliers with efficiency up to 31% and integrated cover glass for radiation and particulate protection. The robust electrical design incorporates a magnetically clean layout, parallel gap resistance welding for cell interconnection, customizable string configurations (parallel/series), built-in bypass and isolation diodes for shading protection, and low-outgassing RTV silicone adhesive for solar cell bonding. Precision mechanical structures offer multiple substrate options: PCB/FR-4 for CubeSats, CFRP plate + FR4 flex for larger configurations, and Aluminium honeycomb with CFRP face skins for microsatellite and large-format panels, along with space-grade hinges, hold-and-release mechanisms, and deployment systems. Customizable interfaces include flexible mounting hole patterns and panel dimensions, external temperature sensors with configurable I²C addresses, and Micro-D electrical connectors with custom bracket options. Applications span communication satellites, Earth observation satellites, navigation satellites, scientific missions, CubeSats and nanosatellites, and LEO constellations. The product portfolio includes CubeSat Solar Panels (1U–16U) with various substrates and configurations, customized deployable solar arrays for microsatellites up to the 100-kg class and beyond (featuring aluminium honeycomb core with CFRP face sheets, precision-engineered hinges and deployment mechanisms, integrated temperature sensors, sun sensors, and isolation diodes, and deployed frequency greater than 2 Hz), and large-format satellite solar panels for advanced satellites requiring high power, based on aluminium honeycomb structures with CFRP skins. Customization capabilities cover panel geometry and size, solar cell type and configuration, deployable array mechanisms, connector and harness layout, mechanical interfaces and hinge systems, thermal design and sensor integration, and full documentation, testing, and qualification support.
