The Sundarbans Tiger Reserve became India’s second-biggest tiger reserve after the National Board of Wildlife (NBWL) approved West Bengal’s proposal to expand its area.
Situated in the coastal districts of West Bengal.
Lies at the southernmost part of the lower Gangetic delta, bordering the Bay of Bengal.
Part of the Sundarbans, the world’s largest delta, formed by the confluence of the Ganga and Brahmaputra rivers flowing into the Bay of Bengal.
Designated as a National Park and a Biosphere Reserve.
Unique as the only mangrove forest (besides Bangladesh’s portion) to sustain a significant population of tigers.
East: International boundary with Bangladesh, formed by rivers Harinbhanga, Raimangal, and Kalindi.
South: Bay of Bengal.
West: River Matla, adjoining the South 24-Parganas Forest Division.
North-West: Rivers Bidya and Gomdi.
Comprises true mangroves (major elements), minor mangroves, and mangrove associates.
Includes a variety of shrubs, non-halophytic (non-salt tolerant) plants, halophytic (salt-tolerant) herbs, shrubs, weeds, epiphytes, and parasitic plants adapted to the saline environment.
Home to iconic species such as:
Tiger (unique mangrove-adapted population)

The Grid Connected Rooftop Solar Scheme was launched by the Government of India with the objective of promoting clean energy solutions to combat pollution and reduce the consumption of non-renewable resources such as coal and petroleum. By utilizing rooftops to generate electricity through solar energy, the scheme aims to provide low-cost power, improve environmental quality, and reduce dependence on fossil fuels.
A Solar Rooftop System involves the installation of solar photovoltaic (SPV) panels on the rooftops of residential, commercial, industrial, and institutional buildings to harness solar energy and convert it into usable electricity.
Solar Rooftop System with Battery Storage:
Includes a battery system to store excess energy for use during night or cloudy conditions.
Grid Connected Rooftop Solar System (SPV System):
DC power generated by solar panels is converted into AC power using a power conversion unit.
This power is then fed into the national electricity grid via 33kV/11kV three-phase lines.
During daytime, generated power is used for captive consumption, and excess energy is exported to the grid.
In case of insufficient solar power (due to cloud cover), the grid supplies the required electricity.
The performance of these systems depends on the user type (residential, commercial, institutional) and regulatory infrastructure in the area.
To achieve 40,000 MW of rooftop solar capacity across the country by 2022.
The scheme has been allocated ₹11,814 crore in central financial support.
Phase II of the scheme offers:
40% Central Financial Assistance (CFA) for rooftop systems up to 3 kW.
20% CFA for systems between 3 kW to 10 kW.
Enhanced participation of DISCOMs (Distribution Companies) to facilitate implementation.
Reduces electricity bills for households and businesses.
Utilizes existing rooftop space, eliminating the need for additional land.
Short gestation period for installation and setup.
Reduces transmission and distribution losses by generating power at the point of consumption.
Contributes to carbon emission reduction and promotes environmental sustainability.
Improves voltage levels at the tail-end of grid lines and reduces grid congestion.
The scheme is implemented by the Ministry of New and Renewable Energy (MNRE), Government of India.
Promote research, innovation, intellectual property, and international collaboration in clean energy technologies.
Encourage deployment of solar, wind, biogas, and hydropower systems.
Reduce dependence on oil-based fuels, especially in transport and cooking.
Ensure energy is accessible, safe, cost-effective, and equitably distributed across India.
Intermittent Power Supply:
Solar energy generation depends on sunlight intensity and is ineffective at night or during cloudy weather.
Expensive Energy Storage:
Battery storage systems, although a solution for night-time or backup supply, are still costly and underdeveloped.
Off-Grid Limitations:
Many remote and off-grid areas still lack effective storage or hybrid systems to ensure 24/7 power availability.
The Grid Connected Rooftop Solar Scheme marks a significant milestone in India’s journey toward a clean and sustainable energy future. It offers a practical, decentralized, and cost-effective solution for reducing dependency on fossil fuels while empowering citizens and institutions to become energy self-reliant.
