Solar Energy

Introduction

The Sun is an infinite source of energy that is pivotal for sustaining life on our planet earth.  It has been harnessing energy from the sun since ancient times to this modern era of ever evolving technologies. Solar radiation can be converted into useful energy such as - solar collectors can provide hot water or air heating, solar photovoltaic cells can generate electricity. 

Nepal is blessed with solar resource as it lies at 30◦ Northern latitude which is ideal and there are over 300 days of sunshine annually. Further the annual average solar insolation is 5kWh/m2 per day.  These conditions are perfect for harnessing solar energy for various conversion technologies.  Broadly, the applications of solar energy in Nepal are -
