Rural Solar Electrification Project

In the underdeveloped world, the major constraint today is capital resource needed for upliftment of rural life.

Electricity is the basic human need. The cost of carrying a transmission line to the remote village is the social responsibility of any civilised government, but it is not prudent economics, because the no of households and their consumption will not justify the investment in economic terms.

It is in this situation, the solar rural electrification is an economically viable option and practical solutions. For rural application, there are three segments to be considered, namely :-

  • Solar lanterns for small household and street hawkers
  • Solar home lighting
  • Solar Street Lighting

These are social projects to uplift the quality of rural life, enable the children to study at night and for rural folks to do local trading at community markets in the night.

We propose a model project limited to one village as experimental project for benefit assessment for the society. We propose a small quantity of each three applications to be installed, put to use in local environment to help the decision makers to arrive at long term plan for rural upliftmen.

Solar Street Lighting


Sun light will be converted into DC Electricity when it falls on the top surface of the solar cells inside the SPV module by means of direct photovoltaic conversion process. The generated electricity can either be directly used during the sunshine hours or may be stored in storage batteries to be used later. Solar Street Lighting System essentially comprises solar PV modules, a battery, electronic luminaire with built in high frequency inverter, charge controller and automatic dusk dawn switching etc.

We offer a wide range of Solar PV Street Lighting Systems with standard and custom built versions. The Standard model generally conforms to MNES specifications.
