我们今天面临的最大挑战之一是找到一个可持续的解决方案，为数百万没有电力的非洲人提供清洁和负担得起的能源。2015年，撒哈拉以南非洲有6亿多人没有用上电，其中60%以上生活在农村地区，农村住宅电气化率低至17%。太阳能家庭系统可以增加撒哈拉以南非洲农村地区的电力普及率。在本文中，使用太阳能家庭系统，采用锂离子电池的可行性进行了研究，特别是考虑到电池的退化。研究发现，暴露于撒哈拉以南非洲的炎热气候下，5年循环后的容量衰减约为20%，相当于约50美元的电池系统更换成本。虽然这本身并不是预防性的，但太阳能家庭系统的前期成本在7 k-21 k美元之间，可以起到威慑作用。
One of the biggest challenges facing us today is finding a sustainable solution to provide clean and affordable energy to the millions of Africans who live without it. Over 600 million people in Sub-Saharan Africa did not have access to electricity in 2015 and while more than 60% of them live in rural areas, the rate of residential rural electrification there is as low as 17% [1]. Solar Home Systems can potentially increase the penetration of electricity access in rural Sub-Saharan Africa. In this paper, the viability of using Solar Home Systems which employ lithium-ion batteries is investigated, particularly considering the degradation of batteries. It is found that, exposed to the hot climates of Sub-Saharan Africa, capacity fade after 5 years of cycling is approximately 20% equating to a battery system replacement cost of approximately USD 50. Although this, in-and-of-itself, is not preventive, the upfront costs of Solar Home Systems, in the region of USD 7k-21k, can act as a deterrent.
