In this study, we examine this issue in closer detail by investigating how temperature affects each of the five characterisation parameters required to char-acterise their electrical behaviour using the single diode five parameter model. It has been shown in a number of previous studies that the overall electrical performance of these cells will deteriorate with temperature, with power output dropping linearly with temperature. Disregarding reflection losses, the remaining portion is absorbed by the cell thus elevating its operating temperature. These solid state devices are only capable of converting a portion of the solar spectrum into electricity. The crystalline silicon type cell is at present the most commonly used photovoltaic device on the market. The whole system has been implemented and tested in our laboratory and found it working satisfactorily with desired accuracy. To make the system fully automatic a driving program has been developed using Arduino IDE and burnt into the microcontroller of the Arduino board.
LDR has been used as photo sensor devices and Servo motors to rotate the solar panel depending on the position of the sun daily and seasonally. Arduino connects the hardware components for our desired works through command codes installed in its microcontroller. To conduct the project work we have used Arduino board and Arduino IDE software.
In this project the design and construction of a microcontroller-based solar panel tracking system is included that allows more energy to be produced because the solar panel will able to remain aligned to the sun so that it can generate more energy than a fixed positioned Solar panel. For the proper utilization of obtaining solar energy from the sun technology upgradation is the vital concern. Harnessing the use of solar energy requires more research and development to improve the efficiency of solar applications but the efficiency of present systems already make solar harvesting a viable commercial option. It offers the greatest energy potential compared with other currently known renewable resources. In the field of renewable energy, use of solar energy is the major concern and utilization of solar photovoltaic energy is increasing day by day.
