Top 7 Largest Floating Solar Power Plants in India

“Today, when the energy sources and excesses of our industrial age have put our planet in peril, the world must turn to the sun to power our future.”

     – PM Modi at the launch of the International Solar Alliance

India has the potential to generate 280 GW to 300 GW of electricity by installing floating solar power plants. It will help the country fulfil its international commitments towards fighting climate change. To harness the potential of solar electricity, the government is now bringing the spotlight on solar power plants on water bodies.

What is a Floating Solar Power Plant?

As the name suggests, a floating solar power plant is a solar system setup on a water body. It converts the sunlight falling on the water into electricity by integrating solar panels on the water’s surface. A country with abundant water bodies can install such systems to generate free electricity and reduce reliance on thermal plants.

Top 7 Floating Solar Power Plants in India

Here’s a list of major floating solar power projects in India:

1. Omkareshwar Floating Solar Power Project

Renew Solar Power Private Limited will develop 100 MW and Shapoorji Pallonji Infrastructure Private Limited will develop 50 MW at the park.

6. Chandigarh Floating Solar Power Plant

Chandigarh Floating Solar Power Plant

Capacity: 2 MW

Cost: Rs. 11.70 crore

Location: Chandigarh

Year of Commissioning: 2023

Chandigarh Floating Solar Power Plant is north India’s largest floating solar power project in terms of capacity. As per a report, it produces 28 lakh units of electricity annually, generating annual revenue worth Rs. 1.38 crore.

It prevents the emission of 80,000 tonnes of CO2 annually. 

The plant will also help to avoid the evaporation of 382 million litres of water annually. Hartek Solar built this project under a contract from the Chandigarh Renewal Energy and Science and Technology Promotion Society (CREST).

7. Mudasarlova Reservoir Floating Solar Power Plant

Advantages of a Floating Solar Power Plant

Here are some advantages of floating solar power plants:

Avoids Land-Energy Conflict

A piece of land cannot be used for any other purpose if it already houses a solar system. When a solar system is built on a water body, land is kept free for other purposes such as agriculture or setting up industries.

Benefits of Co-Location

A floating solar plant can be installed alongside a conventional power plant. The floating plant can use an already existing plant’s transmission infrastructure and avoid expenses on the same.

Reduce Algae Growth

As per a study published in ADS, if a floating solar power plant covers 40% of a lake, it prevents algal blooms. Reduction in sunlight which reaches the algae prevents the bloom. Thus, it improves the quality of the aquatic ecosystem.

Saves Water

Floating solar power plants prevent evaporation by covering the water’s surface. Covering the water’s surface ensures that the water does not get heated up, thus preventing evaporation.

Better Efficiency

A solar panel’s efficiency reduces as it gets hot. The water surrounding a floating solar power plant ensures that the panels remain cool, thus enhancing their efficiency.

Components of a Floating Solar Power Plant

The following components are used in a floating solar power plant:

Components of a Floating Solar Power Plant

Solar Panels

Panels capture sunlight and convert it into electricity. Solar panels use photovoltaic cells for this purpose.

Solar Inverter

An inverter converts the Direct Current (DC) into Alternating Current (AC). This is done because only Alternating Current (AC) can be used to power a home.

Floats

Floats or pontoons are the mounting structures holding the solar panel on water. It is made of High-Density Polyethylene (HDPE).

If you want to learn about the different types of mounting structures for a solar system, you can check my blog on mounting structures for solar panels.

Mooring Lines and Anchoring

A floating mounting structure is anchored using mooring lines. These lines are linked to dead weights at the bottom of the sea bed.

Transformer

A transformer increases the voltage of solar electricity before it is sent to the transmission lines. Increasing the voltage reduces power loss during transmission.

Combiner Box

It combines the electricity generated by all the solar panels into a single output. The electricity is then sent to the inverter for AC-DC conversion.

India aspires to be a world leader in the field of solar power. India’s role as one of the founders of the International Solar Alliance (ISA) is a striking example of the country’s ambition. As a country blessed with abundant water bodies, India can install floating solar power plants to generate almost 300 GW of electricity. It can reduce India’s dependence on importing coal and prevent pollution.

At Das Energie Private Limited, we are on a mission to make the solar installation business transparent. We provide quotations from DISCOM-empanelled vendors for installing your solar system. You can compare quotations to get the most value for money for installing your solar system.
