Ecosense installed Solar PV Training and Research System at Department of Electrical Engineering, IIEST, Shibpur

Shibpur's IIEST serves as a centre for advanced study and research. The creation and transmission of knowledge, the production of highly qualified engineers, scientists, and entrepreneurs equipped with the newest technologies, and the development of innovative technological solutions for societal causes are among the top activities.

The history of the Institute is lengthy. Since 1856, it has been empowering the country. It is India's third engineering college when ranked by establishment year, but when ranked by graduation year, it is India's second-oldest engineering institution. It comprises 8 schools and 16 sections. It has more than 250 staff members and more than 4000 students.

IIEST Shibpur, recently ordered Solar PV Training and Research system from Ecosense for their students to experiment and further their research on Solar PV concepts.

Solar PV Training and Research System

Solar PV Training and Research system is a compact miniaturised version of an actual Solar PV standalone power plant. The system enables user to study wiring and interconnections of different components involved in the system to develop basic understanding of working and operation of a Standalone PV system. Through the help of experiments a student can understand underlying principles of solar PV, its applications in standalone system and challenges like sizing of system, MPPT, installations etc. by doing various experiments. The system also provides scope for further research.


The system is an indoor system which utilises halogen lamps to act as artificial sun to illuminate to solar panels which can be configured in series or parallel depending upon experiments and requirements of users. The experiments are divided into 3 sections: a) Solar PV characteristics, b) Standalone PV system and c) Research experiments. In the first section i.e., Solar PV characteristics there are 5 experiments through which a user can study about Solar PV characteristics, interconnection of solar panel, effect of tilt, radiation and temperature on solar panels and usage of diodes in a solar panel. In second section there are 4 experiments through which user can study about the different components involved in solar PV standalone systems, their interconnection and usage. In third section user can research on maximum power point tracking of the solar panels.


The system consists of individual plug-in units each with components for different experimental arrangement. The conception of system facilitates indoor as well as outdoor experiments.
