 ABSTRACT

 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.
