India’s largest solar photovoltaic plant comes up in Madhya Pradesh

Comments (0)

India’s largest solar photovoltaic plant has been commissioned at Bhagwanpur in Neemuch (Madhya Pradesh). The plant with installed capacity of 151-MW has been developed by the India's largest private solar projects developer Welspun Energy Ltd (WEL).

Details

  • It is expected to supply electricity at around Rs 8 per kWh.
  • Renewable energy has to be given due priority in the wake of our ever growing need for energy.
  • It not only provides clean energy but also is going to be the only alternative to conventional sources of power like coal, gas and nuclear which are bound to finish one day.
  • About half of India’s photovoltaic capacity is located in Gujarat.
  • This plant is supposed to increase country's solar capacity by 7 percent.
  • India currently has a grid-connected solar-power capacity of 2208 MW.
  • The Jawaharlal Nehru National Solar Mission (JNNSM) aims to enhance our solar energy capacity to 20 Gigawatts by 2022.

Top 3 Solar Photovoltaic Plant in India

  • Welspun Solar Plant Neemuch (Madhya Pradesh): 151 MW***
  • Dhule (Sakri, Shivajinagar) Solar Power Plant Maharashtra  : 150 MW***
  • Welspun Energy 50MW Rajasthan Solar Project - Phalodhi, Rajasthan: 50 MW
  • Bitta Solar Power Plant (Adani Power) - Bitta, Kutch District, Gujarat: 40 MW

*** due to subtle differences in Single unit/multiple unit or individual solar plant or solar park there is some confusion regarding the actual status of largest Solar plants in India. So, kindly be careful and bring it to our attention if some factual mistake is there in the listing.

The difference between Solar-Thermal & Solar Photovoltaic technology
Photovoltaic

  • Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. They convert solar radiation into electrical power.

Solar-Thermal

  • It uses solar energy instead of coal energy to boil the water into steam and then use the steam power to move turbines for generating electricity.

2 types of Photovoltaic Plant

Solar Thermal energy plant

  • Thermal cells capture the heat energy from the sun and then use that generate steam by boiling water.
  • Its the steam energy which generates power ultimately by moving turbine.
  • Its also used for heating water and as an indoor heating system.

Concentrating power plant

  • The only major difference is the addition of mirrors and lenses as catalyst to generate more heat.
  • The light from the sun is concentrated onto the photovoltaic cells and that is converted into heat energy.
  • The rest of the process is same.
  • This is more professional and efficient type of technology than the first one.

Difference between Solar Plant and Solar Park

  • A solar plant is an individual power generating unit run by a particular developer whereas a Solar Park is a congregation of such plants at one place for the ease of operation.
  • In Solar Park all the units has a separate transformer to connect them to the grid.

Two types of Photovoltaic Technology

Crystalline:

  • Efficiency is stable and have long life but are difficult to repair if damaged.
  • Land requirement is less (1.6 ha per MW as against 2.6 ha in thin film technology).

Thin film technology 

  • Needs more land 
  • Due to smaller temperature coefficient of maximum power higher the performance improves under diffused light conditions (morning and evening hours)
  • Said to have a shorter life, but advancing development has improved the life span to at least 25 years. 
  • Susceptible to change in atmosphere: fails when condition is overcast or at night"

Largest single-unit CSP plant in the world

  • Abu Dhabi’s Shams 1 concentrating solar power (CSP) plant.

India is planning to install the World's largest Solar Power Plant with 4000 MW Capacity near Sambhar Lake in Rajasthan that will sell electricity at an estimated rate of Rs 5.50 per unit.
