Abstract
Grass cutter machines are very essential in maintaining the surrounding, however, they are gasoline-powered and not environmentally and health-friendly due to the use of a high cost non-sustainable green energy source and emitting carbon dioxide. Thus, a developmental method of research was employed by innovating a solar power grass cutter utilizing a recycled auxiliary fan with power-saving features, and low wattage both for discharging and charging capacity. The uniqueness of its design with a solar panel placed in a backpack and a storage battery inside, its composition and operating performance makes this grass cutter “very acceptable” to the end users. In the fabrication and construction of the machine, the innovation was based on the design criteria. The machine was tested and measured through experimentation using three trials. The system’s design, composition, and operating performance were evaluated using the adopted evaluation sheet by thirty (30) evaluators as experts and end users. The charging rate of the equipment was 700 mA at 29°C to 30°C average heat temperature and it took 10 hours to fully charge the battery when not in use. While the discharging rate was 1,525 mAH and it took 4.59 hours of continued usage to fully drain without the support of the solar panel. On the other hand, the discharging rate of the battery when connected to the solar panel was only 560 mAH and it took 12.5 hours to fully drained the battery for cutting the grass field area of 1,000 sq. meters.
