Solar energy is critical because it does not only sustain global environment, but produce ample power to use. This study addresses solar concentrator layout to maximize profit for the firm manufacturing the concentrator, while helping an energy user receive as much sunlight energy as possible. We consider several key design factors of a solar concentrator layout, such as light transmission loss, to make the model more accurate. As for the economic scale of production, some key constraints are considered, such as concentrator thickness and the number of exits where a sunbeam is delivered to an optical cable for energy transmission. To obtain a high brightness of a good solar concentrator for the user, the concentrator manufacturer requires to increase the complexity of concentrator layout, but suffering from high manufacturing cost. In this study, we simultaneously address the issues of the optimal solar concentrator layout and trade-off of conflict objectives between the energy user and the concentrator manufacturer. This study proposes a non-dominated sorting genetic algorithm for multi-objective optimization solution. To summarize, the result from this study presents a promising solution both for the light efficiency to supply users and the profit of the firm on delivering the solar concentrator layout.
