Solar Panel from Negative Positive Negative (NPN) Transistors

Abstract

INTRODUCTION

The research study was conducted to determine the level of acceptability of solar panel from NPN Transistors in terms of appearance, durability, efficiency, and usefulness; the average duration time of solar panel from NPN Transistor at a given appliance with different wattage like light bulb with 5W, 7W and 18W, radio with 15W, television with 56W and electric fan with 65W; and the significant difference among the ratings given by the group of respondents on the level of acceptability of solar panel from NPN Transistor in terms of appearance, durability, efficiency, and usefulness.

METHODS

Product development and descriptive research design was used to test and analyzed the data gathered from the ratings of 30 respondents composed of the electronic technician and household head from Brgy. Jasaan and Brgy. Oogong Sta. Cruz, Laguna. The statistical tools used in this research study were the weighted mean, standard deviation, and T-test.

RESULTS

After the evaluation process, it found out that there was no significant difference on the ratings made by the electronic technician and household head on the acceptability of solar panel from NPN Transistor in terms of appearance, durability, efficiency, and usefulness. The overall mean ratings of 4.71, 4.24, 4.09 and 4.20 and 4.84, 4.42, 4.13 and 4.27 respectively, revealed that the electronic technician and household head rated the acceptability of solar panel from NPN Transistor in terms of appearance, durability, efficiency, and usefulness as "highly acceptable," "acceptable," "acceptable," and "acceptable" respectively; and based on the gathered data the duration time of one (1) fully charged solar panel increased as the wattage of appliance decreased. The solar panel from NPN Transistor can last long for at least four (4) hours fan an electric fan with 65 watts.

DISCUSSIONS

The findings gathered led to the formulation of the following conclusion: 1. The hypothesis stating, "There is no significant difference in the level of acceptability of solar panel from NPN Transistor in terms of appearance, durability, efficiency, and usefulness" was rejected. 2. Based on the result from the testing process the duration time of solar panel from NPN Transistor increases as the power rating or wattage of a given appliance decreases.
