1. INTRODUCTION

The demand for Solar Light Systems is increasing every day. In Europe today until 2020, the government will use solar light systems. European inventors and investors spend their daily time innovating the power system to save power from households to industrial plants (Kabir et al., 2018). The schools and universities in Europe taught how the solar power system works. Billions of dollars will benefit if the European community adopts these technologies. People are shifting towards using the new power technology, the Solar Power System (Hoffmann, 2006). The Indian Government subsidizes the people using the solar power system, specifically in rural regions with irregular power. The solar lantern/lamp is the alternative power light during regular power cuts or brownouts. The present situation at home is powered by solar energy. Solar energy uses solar cells to convert sunlight directly to electricity (Singh, 2013). The point is stored in photovoltaic batteries and used for lighting required. These power systems are helpful in non-electrified, specifically in rural areas, and as reliable emergency lighting systems not only for domestic, commercial, and also industrial uses. The Solar Street Light system is intended for outdoor use in un-electrified remote rural locations. This Solar system is an ideal application for campus and village street lighting (Allwyn et al., 2022). The system is composed of enough battery storage backups to operate the light for 8-10 hours daily. In response to this situation, the researcher conceptualized and fabricated the Innovation of Solar-Driven Portable Light Device for Instruction Design at Cebu Technological University-Main Campus, Cebu City that can produce a healthy environment to do the job in the context of safe fabrication of the device in the workplace. With the contribution of this device, ease of handling flexibility and maximization. The functions of the device are partly described. This can be used in Electronics exercises in the laboratory or workplace.

2. LITERATURE REVIEW

The world of making Solar Power Technology from the 7th Century Before Christ to the present is familiar (Lewis & Nocera, 2006). Solar technology started focusing the sun’s heat with glass and mirrors to light fires. Today, everything from solar-powered housing to solar-powered cars. The development of solar power technology is very fast, unlike before, century by century and year by year (Chu & Meisen, 2011). The historical development of Solar Power Technology from the 7th Century Before Christ to the 1200s After Death (Perlin, 2022). During the 6th century, the Roman Period, the Hebrew University of Jerusalem build famous large bath houses facing south at the south windows to let the sun’s warmth (McRay, 2008). Sunrooms were so prevalent that the Justinian Code instituted “sun rights” to secure individual access to the sun (Bronin, 2009). French scientist Edmond Becquerel discovered the photovoltaic effect by placing two metal electrodes during his experiment by producing an electricity generator when exposed to lights (Armaroli & Balzani, 2011). The University of Delaware researches and develops energy using thin-film photovoltaic (PV) and solar thermal systems (Luque  & Hegedus, 2011). The University builds the so-called” Solar One.” This was the world’s first photovoltaic (PV) power system for residential. Another study from the United States. The Department of Energy establishes the Solar Energy Research Institute, sometimes known as the “National Renewable Energy Laboratory.” This facility was dedicated to harnessing sun power (Ab Kadir et al., 2010).  In 1983 the total photovoltaic (PV) system produced more than 500 kilowatts (Hiremath et al., 2009). When grid power was available, the PV system was used to pump water and domestic electricity to 15 dwellings. Paul Mac MacCready invented the solar-powered aircraft and flew it from France to England across the English Channel (MacCready, 2006). The aircraft’s wings were outfitted with nearly 16,000 solar cells, producing 3,000 watts of power (Abbe & Smith, 2016). President George Bush designated the Department of Energy’s Solar Energy Research Institute as the National Renewable Energy Laboratory (Laird & Stefes, 2009). The University of South Florida produced 15.9% of thin-film photovoltaic (PV) cells made of cadmium telluride (Lee & Ebong, 2017). There was this expected future track of solar technology. The buildings, either commercial to residential, will be built to combine energy-efficient design and construction practices and renewable energy technology. The potential of solar power in the world is comparable in scale to the hydropower resource of the Northwest. In the desert area, 15 miles by 20 miles would be provided 30,000 megawatts of power, while the electricity needs could theoretically be met by a photovoltaic array within an area of 100 miles (Hegedus & Luque, 2011). Focused on solar power, or solar thermal electricity, could harness the sun’s heat energy to provide a large-scale, domestically secure, and global power supply. The price of photovoltaic (PV) power will be low with old-style sources of electricity within ten years from now. Solar power will be used to electrolyze water, manufacturing hydrogen for fuel cells for transportation and buildings. The Existing Conventional lamp has no stool device attached, which will cause Stress problems after performing machine activities. The Innovated Portable Light Device can give lights without using electric power. It is a solar power device to produce power lights. This research intends to fabricate an Innovated Solar-Driven Portable Light Device for Instruction Design at Cebu Technological University. This Innovated Workstation Portable Light Device can benefit the instructional program of Cebu Technological University–Main Campus specifically for the Electronics Technology students. After the prototyping stage comes the fabrication of the Innovated Workstation Portable Light Device, which can be done by a group of students working as a team. And this will be placed in the vicinity for the use of the following and incoming students. This will lessen the budget while maximizing the resources of the University. This Innovated Workstation Portable Light Device contributes to the instructors’ knowledge in innovating and creating new concepts in their specialization, leading them to do further studies and improvements. With this, they can also arrange the competencies of producing this device for the students, constructing all parts of the project, and working as a group to arrive at the same output that could partly answer the need of providing 70 percent practical training and 30 percent theory. By innovating this device, the students can gradually meet their level of competencies tailored to their particular knowledge, skills, and attitude. Because of their participation, they can acquire the basic skills in essential operation and understanding of solar technology, operations guide of the device, accuracy and safe manner of working habits that can answer the need of the industry being encompassed by this device.

The level of acceptability of the Fabricated Innovated Portable Light Device for Technology Instruction in terms of its design as rated by the experts and students is both Highly Acceptable, with the average weighted mean of 4.68 and 4.70. Regarding ergonomics, it is also Highly Acceptable, with an average weighted mean of 4.63 and 4.64. In terms of fabrication, it is also Highly Acceptable, with the average weighted mean of 4.69 and 4.62. The average weighted mean on the acceptability of the device is 4.67 and 4.65 for experts and students who described it as Highly Acceptable. So, both the experts and the students have the same perceptions of the acceptability of the Innovated Portable Light Device for Technology Instruction. This recent study aligns with the previous research conducted by Hayat et al. (2019), who vehemently claimed that solar energy has a bright future because of its technological advancement and environment-friendly nature. According to the earlier study by Xu et al. (2021), solar energy has become a green, clean, and safe source of energy. As a result, solar energy has attracted the public’s curiosity as a feasible, efficient, clean, and renewable energy source.
