DESIGN AND DEVELOPMENT OF ROOFTOP SOLAR SYSTEM

Abstract

Solar energy is the most emerging renewable energy. Applications of solar energy are increasing for both gird connected and standalone system. Large power grid connection solar systems are developed by giant power companies. But standalone system can be established by normal person at available places of roof of house, office, hospitals, schools etc. That’s why they are becoming much popular than others. At an area of 1000 sq. feet, 8 kWp solar system can be installed. Before install rooftop optimal rooftop area calculation is required. Once installed rooftop roof cannot be used for most of other purposes. In this report standalone as well as gird connected solar system are designed and simulated in MATALB. MPPT being the essential part of solar photovoltaic system is simulated using Incremental conductance plus integral regulator technique in MATLAB environment in chapter 4. For grid connection Vdc control and feed forward control is used. Results are shown in chapter 8. A boost DC-DC converter and inverter are employed to achieve this goal. To implement the system in real time hardware FPGA controller is used. FPGA uses HDL (Hardware Description language) to describe the system.
