Uninterruptible Power Supply Using Self-Adjusting Photovoltaic Blinds

Abstract

INTRODUCTION

With the rapid increase in population and economic development, the problems in an energy crisis and global warming effects are today's cause of increasing concern. Solar energy is one of the primary sources that does not only provide alternative energy resources but also helps minimize environmental pollution. In this study, an Arduino board was used as the brain of the system for the solar panel blinds that will be self-adjusted. The conversion of sunlight to usable electrical energy has been dubbed as the Photovoltaic Effect. Photovoltaic blinds were assessed in terms of the blinds’ efficiency and power output from the panels. This study may be implemented in different households, buildings, and offices to power CCTV cameras.

METHODS

The quantitative research design was used in conducting the study, specifically, experimental research. The researcher used Arduino, solar panels, and light sensors as the main components for constructing the prototype. Two setups were made, non-adjusting and self-adjusting blind, to establish efficiency. Voltage was measured in the morning, noon, and dusk in three days of data gathering. The t-test at 5% level of significance was used to analyze the significant differences between the two designs.

RESULTS

After a series of testing for 3 days, the collected data were then tabulated. The data collected by the self-adjusting photovoltaic blinds was higher than the non-adjusting photovoltaic blinds. It means that the self-adjusting blinds maximized more the sun's rays and the blinds collected the energy coming from the sun. Within three days, the mean of voltage that was collected from non-adjusting blinds was 0.66V and for the self-adjusting blinds was 1.08V. It was therefore found that the self-adjusting photovoltaic blinds increase the efficacy of the solar panel and that the adjustment of the blinds is accurate since it obtained a higher voltage.

DISCUSSIONS

The study proved that the self-adjusting photovoltaic blinds are much more effective in collecting energy from the sun than the non-adjusting photovoltaic blinds. The self-adjusting blinds were determined to yield greater voltage output and as well as the efficiency. The researchers, therefore, reject the null hypothesis of this study since the computed test statistic is greater than 2.35. Conducting the study in a more controlled environment will increase its efficiency and adding more solar panels were suggested.
