Having caught up with the trend of the world, Vietnam has gradually invested and developed in solar energy in recent years. On this subject, to be able to use and manage this solar energy resource well, choose a suitable location to implement a solar project is a substantial concern. With the associated by many important aspects like environmental, economic, social and political, to achieved solar energy effectively we need to depth analysis of those aspects for solar project site selection. Planning by utilizing multi-criteria exploration has interested the attention for a long time to find a solution to subjective and contradictory criteria. Multi-criteria decision-making (MCDM) method put forward certain appliance to be used in managing and bringing comprehensive scaling indicators with each other, it also present relevant assistance for determining and ex-plaining the problem in particulars. With this orientation, the objective of this study is to select an appropriate site in the case of Vietnam put to use the Analytical Hierarchical Process (AHP) which is the world most widely used MCDM method under consideration both qualitative and quantitative element play an effective function in decision makings process. The result indicates that the overall ranking of alternative and decision making (DM) can be achieved through adopted the proposed model. Depending on circumstances, we can modify to get the most suitable criteria for the problem, and with the knowledge in the subjects, experts can assist to determine the importance comparison within and between the factors.
