Ecosense Installs Solar PV Lab at Department of Solar Energy, College of Agriculture Engineering and Technology, Dediyapada, Gujarat. Ecosense’s Solar PV Lab enables users to learn about Solar PV Technology in a very easy and interactive manner. The two equipments installed under Solar PV Lab are:
• Solar PV Training and Research System
• Solar Grid Tied Training System
Using solar PV Lab, a user can understand and experiment on characteristics of Solar PV Panel, Solar PV Standalone systems and Solar PV Grid-Connected/Grid-Tied systems.
Solar PV Training and Research System
1. Ecosense’s Solar PV Training and research system enables user to learn about Solar PV standalone technology. Using this system, a user gains knowledge in three fields of Solar PV Standalone system:
1) Physics of Solar PV Panels — I-V and P-V characteristics, series and parallel connection of solar panels effect of irradiation, effect of temperature, effect of shadow, effect of tilting of panels, effect of geographical location etc.
2) Components and Assembly of standalone system — use of blocking diode, use of bypass diode, use of solar charge controller, use of solar inverter, difference between MPPT and PWM charge controllers, AC load, DC load, battery charging/ discharging characteristics, assembly of several components and power flow calculations in each branch.
3) Research in PV systems — Ecosense separately provides a research unit along with standalone experimental system. User can initiate research in the area of maximum power point tracking using this unit. It has provision of providing automatic as well as manual gate signals to charge controller. User can use his/ her own MPPT algorithm with any of the controller to provide manual gate signals.
This system allows students to learn the concepts in step-by-step manner as first few experiments explains about physics of the system which is very important to understand the science behind the system. It enhances user’s theoretical knowledge about solar PV systems. Then, further experiments lead to components and assembly of a standalone Solar PV Power plant which educates students about what are the components used in a standalone solar PV system, what are their usage and what should be their ideal size to make an optimum functioning Solar PV Standalone power plant. After these basic essential experiments students have all the necessary knowledge about Solar PV Standalone system and to further increase their understanding Ecosense’s Solar PV Training and Research system also offers research experiments where an individual can gradually move to a research mindset from technical mindset. These experiments focus on discovering ways to utilize maximum power from a Solar PV standalone system. These experiments help students/users to start thinking from the perspective of research in the field of Solar energy or renewable energy systems.

Solar Grid Tied Training System
2. Ecosense’s Solar Grid Connected Training system enables user to learn about Solar Grid -tied technology. Using this system, a user gains knowledge of connecting an auxiliary grid (Solar PV) to the main grid, its essential components and transfer of power between the two grids. Using this system user gains knowledge in the following areas:
1) Effect of different types of loads on Electrical Grid
2) Effect of capacitance and inductance in Transmission lines
3) Interfacing requirement of an auxiliary Grid to main grid
4) Concept of anti-islanding
One Day Workshop Conducted
Students attending One-day Workshop
Ecosense also conducted a one-day training program at Department of Solar Energy. This training program was focused on educating and training the professors, scholars and technician in Solar PV Technology who will further train hundreds of students and researchers to start their career or business in this very field.
