Abstract: Choosing the appropriate system configuration that meets the multi-objective of profit-making and environmental protection is always a critical decision for both entrepreneurs and the government. The choice is complicated primarily if several possible alternatives exist. In this paper, a decision framework was developed to select from four configurations, the configuration that best fits decision-makers' multi-objective of profit-making and environmental protection. It was found that, overall, the grid-connected PV-battery hybrid configuration, for now, offers the best fit to the desired profitability and CO₂ mitigation effort with a similarity index of 96.10%. Whereas for now, the standalone PV-batt configuration is only about 29.93% close to this desired objective. It is inferred, therefore, that the complete exclusion of conventional energy from the concept of sustainable energy, for now, leads to an unequivocal increase in installation costs, preventing investments in green technology, particularly in developing countries.
