This research aims to analyze the energy efficiency of smart grid systems in University of Phayao with installed 500 kW solar panels, and to propose ways to increase the energy efficiency of the system according to Life Cycle Assessment framework from manufacturing, transportation, installation, operation, maintenance, and end of life. The results showed that the generated power from grid at 1 kWh uses accumulated energy of 3.61 MJ, while smart grid systems use accumulated energy of 2.252 MJ. The solar panels have the most accumulated energy of 2.234 MJ, which is equal to 99.22 % and making a total energy absorbed equal to 1.347. That means the energy efficiency of smart grid system have good energy efficiency. Therefore, the maintenance of the system to increase the service life from 20 years to 25 years will reduce the accumulated energy of the system by 14.17 %. The guideline to increase the efficiency of the system that will be installed in the future recommends a solar panel with low energy consumption in the manufacturing process, and in addition to being able to reduce the accumulated energy in the system also help increase the system performance in the other one as well.
