Abstract:
The idea of this project is to provide design and practically implementation for alternative , environment friendly electrical feeding system by using solar . it is used to feed all electrical loads in the office of graduate studies and scientific research in PPU during the day through ( grid-tie solar system). This system is differing from the ( grid-tie solar system) that doesnt use batteries to store energy, due to their disadvantages in terms of high cost and higher need for maintenance and replacement.
Advantages of ( grid-tie solar system) include the low operating cost , low maintenance, easy installation, long life and saving in the bills.
At the binging of the project we use theoretical calculation and we found that the office consumes 2.9 MWh/year, after theoretical analysis we find that we need 8 photovoltaic modules and 3KW inverter. Now the system produced 3.5 MWh/year that means the system will feed the loads completely during the office work hours.
However when the office is not working the energy produced by the system will feed the grid.
