Abstract

Solar power is the fastest growing means of renewable energy and it is the future of renewable power generation. The problem with solar panels is that they use up a lot of space on rooftops or open areas and are difficult to mount, maintain and clean regularly. Additionally, the solar panels are to be moved as per sun�s position which can generate up to 40% more solar power. This project proposes a new kind of solar panel that can be mounted on water bodies like lakes, pools so that they don�t occupy any land space. Additionally, this project introduces an innovative sun tracker and panel movement system using Real Time clock (RTC) mechanism to move the solar panels as per sun position and generate more power. This project is designed and implemented using simple dual axis solar tracker system. In order to maximize energy generation from sun, it is necessary to introduce solar tracking systems into solar power systems. A dualSPWMaxis tracker can increase energy by tracking sun rays from switching solar panel in various directions. This solar panel can rotate in all directions. The panels will be fitted with the solar tracker to track the sun to maximize the energy collection. In general, the output of the PV array is unregulated DC supply which is applied as input of Boost (DC-DC) converter and further it is converted to AC voltage by using inverter. The AC output voltage and frequency are regulated. A closed loop voltage control for inverter is developed by using sine wave pulse width modulation (SPWM). The regulated AC voltage is fed to AC standalone loads or grid integration. The overall system is designed and developed by using MATLAB/SIMULINK.
