A STAND-ALONE PHOTOVOLTAIC SYSTEM, CASE STUDY: A RESIDENCE IN GAZA.

Abstract

Harnessing the solar energy to power electric appliances starts by converting the energy coming from the sun to electricity. Photovoltaic is the direct conversion of the solar energy into electricity. Photovoltaic systems can be used to exploit the solar energy in almost all kinds of applications. Exploiting of solar energy for domestic use is one avenue where the energy emitted from the sun is converted into electricity to power most if not all the appliances available at our homes and residences. Building a photovoltaic system is the process of designing, selecting and calculating the ratings of the equipments employed in the system. This process depends on a variety of factors such as geographical location, solar irradiation, and load requirements. In this paper, I introduce the procedures employed in building and selecting the equipments of a stand-alone photovoltaic system based on the Watt-Hour demand. As a case study, a residence in Gaza with medium energy consumption is selected.
