In regions with unstable grid access, families often rely on noisy generators. This case study explores how a 5kW solar system replaced a diesel generator, providing 24/7 silent power and significant cost savings.
In sub-Saharan Africa, over 600 million residents still lack access to reliable electricity supply. Many remote villages are forced to rely on kerosene lamps and diesel generator, or endure complete darkness after sunset. Take Mwanga village in Tanzania as an example: located over 80 kilometers from the nearest urban grid connection, villagers face restricted nighttime activities, and students must complete their homework before dusk.
As a key high school in Pingjiang County, Hunan Province, Pingjiang No.1 Middle School has long been committed to improving educational quality and campus sustainability, aiming to establish itself as a green low-carbon education demonstration base. In 2016, our company actively responded to the "Education Support + Environmental Protection" initiative by investing in and donating a 70kW distributed photovoltaic power generation project. This project supports educational development through clean energy, channeling power generation revenue into rewarding outstanding teachers, pioneering an innovative model of "green energy + educational incentives."
In Chipata Village, Luangwa Valley, Zambia, 90% of villagers have never been connected to the national grid. Households rely on kerosene lamps (mothly cost: $15, consuming 25% income). Lack of nighttime lighting leads to high dropout rates among childre (especially girls), medical clinics being unable to store medicines, and the village’s only small-scale mille operating at a loss due to the high cost of diesel power generation.
