Abstract
En 中文
Currently, the electrical power shortage in Iraq and the existence of programmed stoppage mechanism at the Ministry of Electricity does adversely affects the work of information systems. Videoconferencing is uninterruptable systems which is one of the most important activities in information technology and e-learning systems. The study aims to design solar (alternative) system to run Videoconferencing systems in Iraq. Iraq is one of the ideal countries for the application of such a system in terms of: its geographical location which provides a number of sunny hours at a rate of (6-5) hours per day, and the lack of cloudy days for summer and winter. A method of sizing stand-alone photovoltaic systems regarding the reliability to satisfy the load demand, economy of components, and discharge depth exploited by the batteries is presented in this work. This paper introduced number of necessary mechanisms to increase the economic benefit, as well as the level of scientific services that are supported by this system. The results described in this paper confirmed that the design of system parameters (solar size, charge controller, battery bank, inverter features, size of wiring and base plate moving vertically to measure the angle of inclination (tilt)) are give higher efficiency in the use of solar panels.
