Project Name: Off-Grid Power Supply System Upgrade for a Coastal Fishing Village in Namibia
Namibia, located in southwestern Africa, has several small fishing villages along its long coastline. A certain fishing village, far from the national power grid, has long relied on diesel generators for electricity. This not only incurs high costs but also causes the noise and exhaust from the generators to have a certain impact on the coastal ecological environment. Meanwhile, the high salt spray, strong ultraviolet radiation, and occasional sandstorms in the coastal area place strict requirements on the weather resistance of power equipment.
To improve this situation, the fishing village launched an off-grid power supply system upgrade project. After evaluating the local climate and power demand, it finally selected the 720W N-type Grade A solar cell dual-glass solar panel as the core power supply equipment. This solar panel uses N-type solar cells, which have higher conversion efficiency and a lower temperature coefficient. Under the strong sunlight conditions in Namibia, its power generation efficiency is about 8% higher than that of traditional P-type solar cells; Grade A solar cells ensure stable power generation and long service life. The dual-glass structure, with excellent salt spray resistance and water vapor permeability, can effectively resist high humidity and salt spray erosion in coastal areas. Moreover, its high surface hardness can withstand sandstorms.
Before being put into use, the solar panel underwent targeted tests: In the neutral salt spray test simulating the salt spray environment of the Namibian coast, after 500 hours of continuous exposure, the surface of the module showed no corrosion or bubbles, and the power generation performance attenuation rate was less than 2%; In the high-temperature and high-humidity test (85℃, 85% humidity) for 1000 hours, the output power remained stable; In the sandstorm resistance test, simulating sandstorm impact at a wind speed of 70km/h, the glass surface had no scratches and the circuit connections were intact.
At present, these 720W N-type Grade A solar cell dual-glass solar panels have completed deployment preparations and are about to be put into use in the fishing village. It is expected that after the system is completed, it can meet the basic electricity needs of 30 households in the village (lighting, small household appliances, charging of communication equipment, etc.), reducing diesel consumption by about 5 tons per year. This not only lowers the electricity cost for villagers but also provides a weather-resistant solution model for clean energy applications in coastal areas of Namibia.
