This paper gives an insight into a key arm of Renewable Energy (RE) – Solar PV (Photo-Voltaic). It presents key definitions, processes and technologies behind the Solar PV power generation process. The literature is clarified in such a way as to ensure a primary understanding of the concept and its processes for anyone willing to key into Solar PV as a clean alternative to electricity power generation. With further deepening of knowledge around this area, acceptability and patronage of Solar PV can be enhanced especially within the country Nigeria, leading to a spiral effect with beneficial implications for competitive/cheaper energy prices, reduced air pollution, improved urban-rural energy accessibility, and reduced global warming and climate change environmental effects. This paper posits that the acquisition of basic knowledge and understanding of the concept is critical, and would influence buy-in and patronage. Ultimately, the prospect of a paradigm shift away from fossil power generation to renewable sources is enhanced.
