Enhancing the usage of solar energy has become a crucial target for achieving a sustainable energy supply, as the sun emits immensely powerful energy from the center of the solar system. Advancements in solar PV technology have further paved the way for success in the solar energy industry. However, theory alone is insufficient for developing practical skills among students. The lack of instructional devices can hinder hands-on training and learning. To address this issue, a research study was conducted at Bohol Island State University–Main Campus, Tagbilaran City, during the Academic Year 2021-2022. The objective of the study was to develop a Solar Power Stand-Alone System Trainer and assess its performance level and acceptability. The experimental design was employed in the study. Data relevant to the acceptability of the trainer were collected through a questionnaire, while the performance level was determined using an observation guide. Twenty (20) students pursuing BS Electrical Engineering and BS Electrical Technology underwent a skill test to evaluate the effectiveness of the Solar Power Stand-Alone System Trainer. Additionally, thirty (30) technical experts were involved to validate the performance level and assess the acceptability of the device. The results of the study showed that the use of the trainer led to a significant increase of 34.99% in students' performance ratings. It was also found that the trainer served as an effective instructional tool for subjects related to BS Electrical Engineering and BS Electrical Technology. The trainer received high ratings for its effectiveness and performance, making it a valuable asset in the workshop environment. By utilizing the Solar Power Stand-Alone System Trainer, students' skill competencies can be enhanced, and the overall quality of instruction in the workshop setting can be improved. This research contributes to the advancement of solar energy education and provides a practical solution to overcome the challenges associated with hands-on training in the field. As a result, the pursuit of sustainable energy solutions can be further strengthened.
