This project explores the innovative concept of agrovoltaics, which combines agricultural crop cultivation with solar energy generation on the same land. By integrating photovoltaic (PV) systems with traditional farming, agrovoltaics offers a sustainable approach to meet the increasing global demand for both food and renewable energy.

The project investigates how solar panels can be effectively positioned above crops to simultaneously optimize energy production and support plant growth. Through literature studies, technical evaluations, and prototype development, the team examines key parameters like solar panel tilt, elevation, crop compatibility, and local climatic conditions.

A prototype model was constructed using a wooden structure with solar panels elevated 1.5 feet above a crop tray, angled at approximately 24° as per Rajkot’s latitude. The model demonstrates the feasibility of dual land use and was designed for small-scale energy applications like charging low-power devices.

Field interactions with faculty, farmers, and domestic users provided practical insights, validating the dual benefits of enhanced land productivity and reduced environmental footprint.

This project underlines agrovoltaics as a promising solution for sustainable development, with the potential to reduce greenhouse gas emissions, optimize land usage, and contribute to food and energy security in an eco-friendly manner.
