Estmation of Clear Sky Solar Radiation for Dhaka City

Abstract

Solar electricity is one of the most emerging technologies around the world. In almost every corner of the world people are doing research works on how to improve the efficiency of this technology. This is because the solar cell technology, to produce power is still not that much highly efficient considering both the costs and the amount of power produced. Solar power is rapidly gaining notoriety as an important means of expanding renewable energy resources. It is technology of obtaining useable energy from the sun. Sun provides energy in the form of radiation over the UV, visible and infrared spectrum. Only certain wavelengths are used to produce electricity by the solar cell. It is necessary to calculate solar radiation and to estimate the PV output power on any particular day of the year for various applications. To run photovoltaic systems properly the estimation of PV output is also important The output power of a PV panel can be estimated if the amount of solar energy incident on it, efficiency of the panel and its area are known. The area and the efficiency of a panel can be obtained-from the manufacturer's data. In this thesis, we calculate clear sky solar radiation for Dhaka city. The details of the calculation and analysis can be found in the whole report. All the calculations, tables and graphs shown in this report were done in the Microsoft Excel Worksheet
