Decentralized Systems

Decentralized commercial applications—installations between 50 kW and 5MW—represent a promising growth opportunity for solar energy.

      Renewable energy technologies are ideally suited to distributed applications, and they have substantial potential to provide a reliable and secure energy supply as an alternative to grid extension or as a supplement to grid-provided power. Over 400 million people in India, including 47.5% of those living in India’s rural areas, still had no access to electricity. Because of the remoteness of much of India’s un-electrified population, renewable energy can offer an economically viable means of providing connections to these groups. Some of the renewable energy technologies that are used in villages and rural areas as decentralized systems are:

• Family-size biogas plants.
• Solar street lighting systems.
• Solar lanterns and solar home lighting systems.
• Solar water heating systems
• Standalone solar / biomass based power generators.

     Decentralized PV plants are ideally suited to power remote cell base tower stations and rural village electrifications.
      Many of these systems have been found useful in urban and semi urban areas also to conserve the use of electricity and other fossil fuels. Solar water heating systems have helped in demand side management of electricity in various cities and towns during peak hours. Standalone roof top SPV systems are getting popular for day time diesel abatement in areas where power cuts are very high.
