SOLAR IN SRI LANKA ? AN INTRODUCTION

The Sri Lanka governmental policy directions for power sector envisages that the hydro power generation potential of the country will be developed to its full potential as it is the major indigenous resource for power generation as at present. Under this policy, all large-scale hydropower generation facilities are to be remaining under government control for the foreseeable future. Private sector financing will be utilized for power generation from small hydro power plants. CEB Assistance Provided for the Development of the Mini Hydropower Sector Ceylon Electricity Board has promoted generation of electricity using Renewable Energy Resources since early nineties by giving the required assistance to the private sector, which includes training & capacity building, pre feasibility studies and resource assessments. The procedure for electricity purchases from small power producers (SPPs) by the CEB was regularized beginning 1997 with the publication of a standardized power purch...

Derived from the Greek word “phos”, meaning "light," and from volt, which was named in honor of the Italian physicist Alessandro Volta, photo-voltaic (PV for short) describes materials with the property of producing electricity when exposed to sunlight The most common and most efficient photovoltaic products are made from crystalline silicon, representing over 95% of the market. Cell Types Mono – Crystalline The solar cells in monocrystalline panels are slices cut from pure drawn crystalline silicon bars. The entire cell is aligned in one direction, which means that when the sun is shining brightly on them at the correct angle, they are extremely efficient. So, these panels work best in bright sunshine with the sun shining directly on them. They have a uniform blacker colour because they are absorbing most of the light. Pure cells are octagonal, so there is unused space in the corners when lots of cells are made into a solar module. Mono panels are slightly...
