EXECUTIVE SUMMARY: This research study aimed to develop a Domestic Refrigerator utilizing solar energy. Specifically, it sought to design and construct a device out of locally available materials; perform try-out and revision; evaluate the acceptability in terms of functionality, usefulness, maintenance and safety features; moreover, test the significant difference features; moreover, test the significant difference on the evaluation made by the experts and end-users in terms of the above mentioned criteria; furthermore develop a user's manual for the sequential operation of the device. This research project focused on the development and utilization of Solar Energy for Domestic Refrigerator. This was conducted at the University of Rizal System Morong Campus by the students of Bachelor of Technology major in Electro-mechanical A.Y. 2016-2017. It was limited to the design, conceptualization, construction, testing and revision. This also made for instructional purposes, to ensure the learning process on how to assemble and construct ducts and calculating loads correctly. This study utilized the developmental and descriptive methods of research since this is a purposive study designing, calculation and constructing Utilization of Solar Energy for Domestic Refrigerator which considers electricity as its source. Validated researcher made questionnaire checklist was used to determine the acceptability of the utilized solar energy for domestic refrigerator, experts in Electro-mechanical and other instructors involved to validate the instructional device. In terms of design and construction of the device, it was constructed and developed out of low cost and locally available materials. On try-out and revisions the device was tested for operation where different weaknesses were manifested. Through try-out and revisions of the project reached the functional output and attained the project objectives. On the acceptability of the completed output of Utilization of Solar Energy for Domestic Refrigerator, it was verbally interpreted as "Very Much Accepted" respectively in terms of functionality. In terms of usefulness the device merited a verbal interpretation of "Very Much Accepted". In terms of safety features the device obtained a verbal interpretation as "Very Much Accepted". The user's manual was developed with different content such as the specification, important safeguards and how to use. Based from the result of the study, the researchers arrived on the following recommendations: Training institution should encouraged the students to design and construct device to help experts and end-users. Feasibility should be conducted to further enhance and improve project.
