Shortly after the financial crises in 2008 and 2009, overcapacities in solar module production led worldwide to a sharp decline of raw material and photovoltaic module prices. Solar module manufacturers sold their modules even under production costs to stay competitive in the market which finally lead to several bankruptcies and financial difficulties of Chinese, European and American manufacturers. In 2012 to 2014, we have seen a consolidation of the production capacities and the worldwide PV market still continues to grow. The feed-in tariffs will fade out because photovoltaic power generation has reached in 2013 grid parity. Production costs of photovoltaic grid connected power generation have dropped to 14 € cents/kWh (19 US cents/kWh) in the northern hemisphere and to 8 €cents/kWh (10 US cents/kWh) in the African sun belt.
The feasibility study on stratified energy access by photovoltaic power in Niger covers two major subjects. Starting point is the insight analysis of the current situation in Niger for photovoltaic systems, recommendations for the best practice photovoltaic technologies to be applied in the context of Niger and the creation of a financial model which allows to scale up the use of photovoltaic power for rural electrification.
