  • Solar Tracking and Pyranometers

    Sutron Corporation

    The demand for energy increased rapidly over the past few decades and the trend is not expected to stop in the near future. These made researchers focus on renewable energy sources due to the environmental pollution caused by the existing conventional energy sources. Solar energy is one of the renewable energy that has been under deep research. Unfortunately, the main problem with this solar energy is lack of efficiency. Different positions of the sun throughout the day causing the static photovoltaic modules position inefficient. This paper discusses design of two-axis solar tracking system that considers multiple input parameters such as solar radiation and photovoltaic module output power for more efficient solar tracking algorithm. Some of solar tracking system conducted by other researchers uses various types of sensors including light dependent resistor (LDR) which is not efficient and can be easily affected by external environmental factors. Instead, this paper proposes the usage of pyranometer for measuring solar radiation as one of the input parameters. The solar tracking system controlled by PIC microcontroller that collects multiple input parameters and uses developed algorithm to control stepper motor movement for optimal photovoltaic module positioning.
