Dhara engineering manufactures solar home lights/lanterns/street lights using thermal energy as well as solar energy heat, which conserves conventional fuel like oil, coal, gas and diesel and thereby reduces industrial air pollution. These spv systems like portable solar lanterns, home lightening and street lightening systems are supported through subsidy. These solar home lights/lanterns/street lights are available with solar photovoltic technology that uses solar cells for generating electrical energy directly from sunlight. The solar lights/lanterns/street lights using solar photovoltaic technology are an ultimate solution for rural and backward areas where usual grid supply is irregular or non-existent from the past decade. These photovoltaics technology used in these lights have ushered an international growth with features of low price of solar power than that of conventional fuels. These solar home lights/lanterns/street lights are the economical and practical solution for independent energy needs.
