This is because past in-field experience has shown PV designers that
such systems are generally well accepted by the rural users, while the same is not always
the case when small (20–30 Wp) PV modules are concerned. This way, the SHS scenarios
elaborated by PV designers must therefore be interpreted as explanation exercises, rather
than as designs for systems starting from an evaluation of actual needs (see Chapter 23
for discussion of rural electrification programmes). So, we must conclude that energy
scenarios for rural electrification purposes are still an open question, which need to be
explored in-depth.
