Solar PV is an economical viable technology to provide off-grid systems with clean energy. Especially in comparison with diesel generators high cost reductions can be achieved. Nevertheless the implementation of solar systems faces some challenges due to missing business models. Thus, it is important to research, improve and discuss various potential business models.
