Africa is the new solar frontier for many large solar investors, given the huge energy demand and lack of capital. The country has very low 
Chinese and European solar investors are also targeting stable African countries with large energy needs such as Nigeria and Ghana. South Africa has already concluded two rounds of a very successful renewable energy auction program. I am not sure whether these investors will succeed in their ambition of building massive solar farms. There will be the question of how the electricity will be paid by poor African countries, given that solar energy is still much more expensive than fossil fuel energy.
Africa will definitely see very high growth in solar energy because of the falling costs of solar energy and the rising demand from African customers. The way to go is to increase rooftop solar penetration and use of micro grids in villages. Africa can pioneer a new distributed green way of energy generation and consumption given the low level of electricity infrastructure maturity. The continent does not have a large power grid which means that solar energy can circumvent the need to for massive investments in electricity distribution and transmission lines.
