Photovoltaic Applications for Lighting Load Energy Saving: Case Studies, Educational Building

Renewable energy is generally defined as energy that comes from natural resources such as sunlight, wind, rain, tides, waves and geothermal heat energy. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. In this Work one of the Renewable Energies is being focused which is solar energy that it can be used in different two ways Solar Thermal or Solar Photovoltaic; as Solar power (Electricity) is produced in two ways: Direct Transformation from PV or Concentration of solar energy to create steam in order to drive a turbine. Photovoltaic (PV) devices are discovered with their types based on the type of silicon used, specifically; (Mono-crystalline Silicon Cells, Poly-crystalline Silicon Cells, Amorphous thin-film Silicon Cells); Also, different factors that can affect the efficiency of solar panel mounting systems are discussed. PV Systems (Stand-Alone System or a Grid Connected System) with their configurations is discovered and discussed briefly. As Smart Grid is an Electrical Grid in which it includes varieties of operational and Energy Measurements such as Smart Meters, Smart Appliances, Renewable Energy Resources, and Efficiency Energy Resources from here PV Systems as one the Renewables resources in smart grid is introduced. The Study is for Supplying Building (A) – BUE with power and loads was assumed to be 921364.7059 Wh/day and the no. of modules required was 2000 PV module. In order to install 2000 PV Module, it requires 4000m
²
Area and the building roof area doesn’t support to install all this number of modules so it is assumed to be installed in another area land beside the BUE location. A MATLAB Program Code was Generated to estimate the Monthly Averaged Global Solar Radiation at BUE Location and also another Code was generated to Draw the (I–V) Curve for the Selected PV Module.
