Chapter 1 INTRODUCTION Sun is the ultimate source of energy. Life on earth would not exist without the heat and light provided by the Sun. Harnessing the energy from the sun for hot water and electrical power could provide a renewable, low carbon energy source, and presents an attractive way of mitigating climate change. PV cell photovoltaic is the direct conversion of light into electricity. It uses materials which absorb photons of lights and release electrons charges. 1.1 Photovoltaic systems A Photovoltaic system is an arrangement of components designed to supply usable electric power for a variety of purposes, using the Sun as the power source.

Chapter 1 INTRODUCTION Sun is the ultimate source of energy. Life on earth would not exist without the heat and light provided by the Sun. Harnessing the energy from the sun for hot water and electrical power could provide a renewable, low carbon energy source, and presents an attractive way of mitigating climate change. PV cell photovoltaic is the direct conversion of light into electricity. It uses materials which absorb photons of lights and release electrons charges. 1.1 Photovoltaic systems A Photovoltaic system is an arrangement of components designed to supply usable electric power for a variety of purposes, using the Sun as the power source. All photovoltaic (PV) systems are similar in nature but differ in details from each other.It is therefore necessary to have a general view if the system design..Figure below shows the types of solar powered systems currently in use. Fig 1: Types of PV systems in use [1] Photovoltaic systems are broadly categorized as: • Stand-alone Photovoltaic systems • Grid interactive Photovoltaic systems 1.1.1 Stand-alone Photovoltaic systems Stand-alone or off-grid systems include common applications such as Solar lanterns,solar home and street-lightings systems,solar water pumping,stand-alone power plants foe powering appliances in remote areas away from access to grid electricity.Such systems are designed with or without battery backup options.The terrestrial systems can operate in a standalone mode for both AC and DC loads
