Abstract
Solar energy is one of the most abundant and cleanest sources of renewable energy. It is freely available and is one of the most promising in which power generation has many advantages, and because if this it has been gaining prominence as an alternative energy source.
The general purpose of this study was to design a machine that can aid in optimum recovery of this energy-solar power and utilize it for irrigation. Hence, it employed solar tracking mechanism and smartflower design. The machine was composed of these main components namely: photovoltaic PV modules, light dependent sensors (LDR), solar tracking assembly, solar pump and controller, charge controller, battery, voltage sensor, current sensor, arduino microcontroller sets and the trailer.
In this system, 8 PV modules which were positioned in a resembling a flower-like formation were used with a working voltage of 100W (Pmax), 17.6V (Vmp) and 5.71A (lmp). Four LDR sensors were uaed for the dual-axis tracking of the machine. Solar pump and the controllers were the load needed to supply the machine. the load, which is the solar pump, require one horsepower.
Results of the evaluation showed mean voltage and current of 132.65 and 1.98 respectively giving an average power of 258.1. the findings also displays that around 12 noon has the highest power accumulated. Cost of the machine was computed at Php 87,251.31 which is material and labor cost. Annual fixed cost and variable cost was calculated at Php 15,101.19/yr and Php 9.20/hr respectively. Payback period determined at 1.84 years.
