In this project, Shenzhen Kongfar Technology implemented an off-grid solar power system for cargo ship crew cabins. Traditionally, ships relied on diesel generators for electricity, resulting in high fuel consumption, noise, and emissions. When engines stopped at ports, auxiliary generators had to run continuously, consuming 50–80 liters of fuel daily.
To support green shipping and reduce operating costs, the company introduced 10 × 500W high-efficiency solar panels and 3 LiFePO4 batteries to maintain onboard electricity during docking periods.
✅ Reduced operational costs by over 60%.
✅ Eliminated fuel anxiety and minimized generator noise.
✅ Aligned with global sustainable maritime standards.
