Shifting generation of energy of solar PV using OPTANG method-case study Sandwip area

The objective of this paper is to discover the amount of shifted energy produced by solar photovoltaic panel from lower demand period to higher demand period using the optimum tilt angle method. When the incident ray is at right angles to the panel plane, the output of a panel is highest. For maximum generation, the alignment of the panel should be changed according to the sun´s position due to variations in the locus of the sun over the year. However, solar tracking system may not be suitable for this purpose as it requires high cost, maintenance and space. For an isolated area demand profile and generation profile may not be same and hence surplus or shortage will be occurred. It is hardly possible to use surplus energy considering certain demand profile constraints. Even, it is not possible to store the surplus energy of a season to any device for long time to use it for another season. Optimum tilt angle (OPTANG) method has been analysed for an isolated island of Bangladesh and shown that it is possible to shift the surplus energy to shortage season from surplus season.
