Background

The 10 kW floating solar power installation in Rajarhat, Kolkata is the first of its kind in India. The Project was part of an R&D venture jointly undertaken with Arka Renewable Energy College in Kolkata and New Town Kolkata Development Authority and was funded by the Ministry of New and Renewable Energy. The solar power facility was designed using 1 kW fibreglass PV modules to produce a minimum of 14 MWh of solar power annually.

Objective

The main objective was to explore unutilized water bodies and not consume the ever-decreasing land. The requirement was of a solar power generating system that would be suitable for any water body, with the flexibility of being expanded in any other given environment.

Challenges

The biggest challenge in this Project was installing the solar power plant in water. The system had to be suitably designed to stay afloat and be able to withstand the force.

Planning & Execution

Following extensive research and planning, the floating solar power facility was designed to be completely flexible and efficient. The system consists of ten 1 kW fibreglass modules which make up the floating platform or pontoon. The floating mechanism functions successfully with the system anchored firmly to the bottom of the lake and connected to the grid using submersible cables.

The installation consists of 40 highest efficiency 250 Wp Tier 1 Eldora Prime Series polycrystalline modules and a Kaco-made inverter. The inverter’s inbuilt data logger is used for remote monitoring via GSM modem and a bi-directional meter is installed to monitor the NET export.

Results

Vikram Solar is proud to have successfully completed the installations of India’s first ever floating solar power plant. The overall system is designed to last for more than 25 years and generate a minimum of 14MWh solar power annually.
