Abstract


In Pakistan there is a growing gap between supply and demand of electricity and ever increasing  cost per unit of fossil fuel based thermal power generation. This necessitates the need to diversify the energy-mix and increase the role of renewable energy sources like solar in the strategic planning for future. In this work, a low cost parabolic solar collector has been designed to heat water up to 150° C for use in city of Multan. Its orientation and average monthly tilt angles have been estimated & optimized on monthly bases. Moreover, solar radiations for the designed collector at the optimum tilt angles have been estimated. The importance of the work is that it will be helpful in disseminating the low cost indigenous solution which will help in reducing the fossil fuel import bill.
