MATLAB Simulation based Analysis of Tilted Mount Solar Sensor Design for Various Degrees of Angles between Sensors

Divakar Tamang and O.P. Roy

The use of solar energy as an alternative source of energy has been increasing on a regular pace due to its advantages over other sources like availability, pollution free etc. which is also complemented by the advancement in the technology of the photovoltaic (PV) cells. To increase the area of illumination falling on a PV panel, a tracking system is required to track the movement of the solar irradiance throughout the day. The tracking system discussed in many articles though used different kinds of light sensors with different arrangements to track the movement of the sun, does not provide a clear analysis in terms of its best and optimal arrangement for better construction of the sensor design. In this paper a tilted mount design for solar sensor has been considered for various angle between the sensors. For its simplicity the sensors used in the tracking system is assumed to be working in the linear region. The purpose of taking various angles between the sensors is to find out the best and optimal possible angle between the sensors for its better design. The analysis shows that error between the position of the sun and the tracker is minimum for smaller angle between the sensors and also the response time of the sensor is less for smaller angle between sensors and keeps on increasing as the angle between the sensor increases. This helps in the design of a complete system with possible combination of angle between tilted sensors for the required output power from the PV panel. All the simulation have been carried out in MATLAB environment.
