摘      要：Standalone Solar PV systems have been vital in the improvement of access to energy in many ***,given the large cost of solar PV plants’components,in developing countries,there is a dear need for such components to be subsidised and incentivised for the consumers to afford the produced ***,there is a need for optimal sizing of the solar PV plants taking into account the solar information,energy requirement for various activities,and economic conditions in the off-grid regions in *** study aims to develop optimally sized solar PV plants suited to rural communities in ***,it aims at characterizing the impacts of subsidies and incentives on the profitability and affordability of solar PV plants’energy in *** the study,we have developed a model on basis of which the plant power(peak power)and costs of energy can be predicted given the load requirements using *** model was validated using data corrected at eight different *** generalized predictive model’s results matched the results obtained using field measurement data as *** models have been able to replicate with a by degree of accuracy the peak powers and the plants’costs for different loads and were used to evaluate the economic viability of solar PV plants in *** was found that with incentives and subsidies of 20%,the solar PV systems’costs,the Levelised Cost of Energy would drop from a maximum of 0.098 Euro to a minimum of 0.072 Euro,the payback period was reduced from a maximum of 7.5 years to a minimum of 6.0 years while the return on investments was seen to vary between 425.72 and 615.32 per cent over the plants’lifetime of 25 *** our findings underscore the importance of government subsidies and incentives for solar PV energy generation projects to be significantly profitable.
