<br/><br/> The design, development, construction, and evaluation of a Zero Drop Solar<br/>Charge Controller were thefocus ofthe study to contribute in the development ofsolar<br/>power system. The study involved development phase which covered the technical<br/>feasibility ofthe design while the descriptive evaluative phase covered the assessment on<br/>technical performance, economic feasibility, environmental soundness, political<br/>acceptability, and socialacceptability (TEEPS) ofthe device by experts and users in the<br/>community. Basedon the design andperformance testing, it wasfoundout that the device<br/>was functional and a reliable means of charging a battery. Technical performance,<br/>economic and financial viability, environmental soundness, political acceptability and<br/>social acceptability were all found to be highly viable and valid. Therefore the developed<br/>device is feasible for business undertakings by having a 49.15 percent of ROI and a<br/>payback period of I year and 43 days.
