| 总结: | Currently, solar power generation brings many long term benefits such as low
operating cost due to no fuel needed and environmental friendly. In solar technology,
the sun energy is captured by using photovoltaic (PV) panel and converts the solar
radiation into electricity. To maximize a solar module’s power output the module needs
to receive as much direct sunlight as possible. A dual axis solar tracker allows a
mounted PV panel to remain perpendicular to incident sunlight, thus maximizing
power output. In this research, works are focused to overcome the weaknesses in the
current tracking system especially for portable and mobile application. Therefore, this
study focuses on designing and developing a portable dual-axis solar tracking system
that focuses on portable and mobility purpose. Furthermore, this study proposed an
electronic control system with embedded sun’s path trajectory algorithm purposely for
maximizing the power generated from the attached PV panel. The tracking system
utilizes the GPS module and a digital compass sensor for determining the location and
the heading feedback of the system respectively. Moreover, the microcontroller based
tracking system is embedded with a PID controller for which will increase the PV
positioning accuracy by using the feedback signal of the absolute encoder.
Furthermore, the research also analyses and compares the output performance between
the fixed-tilted PV panel and the developed portable solar tracking. |
