<![CDATA[Purpose: designing a small-scale solar power plant system that suits the solar potential in coastal areas to meet the lighting needs of docks and public facilities. Method: this research uses descriptive-quantitative methods through field measurements, engineering calculations, and system design to produce a small-scale solar power plant design that meets the lighting needs of docks and public facilities in coastal areas. Findings: research has found that Kuala Tungkal has significant solar energy potential for solar power plants. A 200 Wp panel produces 730–970 Wh per day, and for a typical home, 16 solar panels and 13 batteries are required. However, weather and cost are significant constraints. Implications: solar power plants have significant development potential in coastal areas and can increase community energy independence. However, they require appropriate design, sufficient batteries, and financial and technological support to address weather and initial investment challenges. Originality: providing field data on solar radiation in Kuala Tungkal, modeling the design of a small-scale solar power plant based on real conditions, and producing practical calculations of panel and battery requirements specifically intended for piers and coastal public facilities, which has not been widely studied before.]]>
