Investigating the Optimum Tilt Angle for Solar Receiver in Izmir

Nowadays, Renewable Energy Resources (RESs) are used widespread in the most industrial countries like Turkey. Solar energy is deem as one of the most potential RESs; that has gained high attention recently. The performance of any solar collector or photovoltaic model is not just limited to its manufacturing characteristics and used advance technology but it also refers to the other parameters that ensures the maximum solar radiation can be obtained by the solar receiver. In this paper, optimum slope angle for stationary receiver is investigated. Empirical equations of Liu and Jordan method are developed to estimate the optimum angle and maximum solar radiation by using MATLAB software. The case study area and measured data are conducted in Izmir city. The results are obtained per month, season and a year and then are analyzed and compared between monthly average daily and representative day of each month. The comparison is yielded that, the difference of maximum radiation on tilt plane does not exceeds 2.6% due to correlation coefficient R2.
