Solar Home Systems (SHS) combined with LED lamps provide
an effective solution for this problem. Especially the use of solar
energy makes much sense in this context as the most affected
regions have favorable solar conditions, i.e. relatively high irradiation
values along the year [1]. Unlocking the PV potential in the
Sunbelt countries would tackle their major energy concerns by
covering their accelerated demand growth with low-carbon,
domestic energy sources [2]. On the other hand, LED lamps are
very energy efficient; roughly an installed total of 60 W is sufficient
to provide high quality light for a family house in a developing
region. The SHS can also provide electricity for the recharge of
electronic devices such as mobile phones. These consume very
little electricity, while having a very high added value. A total
energy demand of 250 W h per day would suffice to cover the
needs highlighted here for a family. Such small SHS have the
potential to bring huge socio-economic and environmental
advantages to developing regions around the globe. Thereby, its
evolutionary aspects are very favorable thanks to ongoing
