چکیده
Depletion of fossil fuels, increase in energy demand, escalation of cost of fuels and environmental pollution has enforced all the countries to give thought on using the renewable energy sources. Among all the possible renewable energy sources solar energy may be a better substitute. The main objective of solar energy application is its collection by collecting device of suitable shape and proper orientation. In this paper, an attempt has been made to develop a mathematical model for optimum orientation of a south facing flat plate collector. The model is studied in connection with the prediction of month wise optimum slope for a flat plate collector for two Indian locations, Kolkata and New Delhi. The study reveals that the present model for optimum slope of a south facing collector can safely be used for locations with latitudes from 0 o to 40 o . The present investigation also includes a comparative performance analysis of the present method and the methods available in the literature. The comparative study reveals that our formulation provides better results.

متن کاملThe Possibility of using Flat Plate Solar Collector Based on the Best Calculated Tilt Angle in the City of Rasht as a Case Study (TECHNICAL NOTE)
The possibility of using flat plate collector in northern parts of Iran specially city of Rasht has been investigated in this paper. According to the high humidity in the northern parts of this country, diffuse radiation plays a more important role than direct radiation. This fact can change the results of delivered solar energy and the best tilt angle of the collector compared to the sunny cen...
