Using photovoltaic systems in constructions to benefif from solar energy

A major portion of the energy resources used in the world are fossil based (coal, oil, natural gas, etc.) energy resources. Nowadays, reduced fossil and almost exhausted most of energy resources are forced people to find new energy resources. Sun that provide eternal solar energy, leads to alternative of fossil energy resources. Photovoltaic sun batteries are developed to obtain electrical energy from solar energy that is renewable energy resource. And the photovoltaic systems are developed depending on these photovoltaic batteries. Large amount of energy are consumed by buildings. This rate is approximately 30% of whole energy. Photovoltaic systems are applied on roof and facade of buildings to provide required energy by renewable energy. In this study, application forms of photovoltaic systems in buildings, using photovoltaic systems in other infrastructure components and applications on peripherals, samples of the use of photovoltaic systems in the world and in Turkey, encouragement and support on solar energy systems in the world and in Turkey; are searched and recommendations are provided.
