Solar Thermal Training system is a compact system in the form of a working laboratory model. This system helps students to evaluate the performance of a Solar water heating System under different atmospheric conditions like temperature, pressure, wind, radiation etc. The experiments can be performed both in the Forced environment and also in the natural atmospheric conditions.
Solar concentrator training system includes the parabolic trough collector to concentrate the solar energy. This system helps students to evaluate the performance of a Solar parabolic trough System under different atmospheric and design parameters with water and oil used as working fluids.
The solar PV training system covers the fundamentals of solar PV system as well as basic research on PV system and related electronics which would be helpful to the engineering students of both undergraduate and postgraduate level.
A Solar Grid-tied System is a grid-connected PV system which links solar power generated by the PV modules to the mains. It acts as an interactive medium where the demand for electricity is fulfilled by the conglomeration of PV and mains. This equipment gives a deep insight into the dynamics of a Grid Tied system and its operation and maintenance.
Solar PV Emulator is a programmable power supply designed to emulate solar panels. With the fast-transient response, the emulator responds to change in load conditions and maintains the output on IV characteristics of the selected panel for a given ambient condition. This instrument is designed to emulate output of solar panels from different manufacturers, variations due to time of the day, effect of season and different geographical locations of installation.

Solar energy laboratory is fully equipped with state-of-art measurements and instrumentations to research solar energy systems; namely, the pyranometer, anemometer, hydrometer, thermal imaging camera, UV radiometer, multimeter and data logging systems. The solar radiation, wind and ambient data are measured at the site. Key research areas are the design of solar receivers for concentrated collectors, solar dryer and drying chambers, thermal storage systems, thermoelectric power generators, solar cookers and thermal management of buildings.
The students are not only involved in the lab-level experiments but also, they are allowed to explore and apply their knowledge in the real-time solar thermal and PV power plants like 100 kW Solar PV plant and Parabolic dish-based steam cooking plant inside the Kattankulathur campus. Students are made industry-ready by the working on indoor and outdoor experiments.

- The parabolic dish solar collector of 16 m2 aperture area is used to produce a concentration ratio of 120 with the selective solar receiver. This experimental test facility is useful to test the new receiver designs with enhanced energy and exergy efficiency. A thermoelectric module can be used to produce cooling and this is tested by integrating with the solar PV emulator indoor and the real-time testing also may be tested outdoor using concentrated solar collectors. Thermal energy storage is used to design the component level research at the lab-level and the successful implementation of the non-concentrated and concentrated solar thermal systems.
