Analysing flat collector efficiency factor in solar water heating systems by simulation

In today?s world where sources are limited and industrialization is quite fast, increasing energy demand and because of this, searching of cheap and renewable energy sources takes a long time of countries. Searching of the cheapest renewable energy sources brings solar energy to mind in the first place. Solar energy is a natural and renewable source. Taking advantage of this may be the simplest solution. The amount of energy that the sun supplies is enormous when considered all of surface of the world. But, it is hard to benefit from it in a limited area.This thesis is dealt with water heating systems where solar energy is being used commonly. The structure of flat collectors which operate with solar energy is simulated in a computer by formulating and it is aimed to determine which parameters are more important in view of efficiency factor of the system using the data obtained.Five of parameters are taken as example and it is observed that emittance of plate amongst these parameters has more positive effect on efficiency factor than the other four parameters.
