Abstract Among the measures to apply renewable energy to data centers, solar power generation is considered to be the most applicable and renewable energy currently available because of the physical conditions in which containertype distributed data centers are installed outdoors and data centers are operated 24 hours a day. Therefore, when the telephotovoltaic system was applied to distributed data centers based on domestic weather data, energy simulation was conducted, and the applicability of the system was evaluated through economic evaluation. As a result of the analysis, the average monthly predicted consumption was 8151 kWh, 9021 kWh, 9388 kWh, and 9712 kWh, respectively, in the four regions, and the overall average monthly energy consumption was calculated as 9068 kWh. The average power generation was 518 kWh, 616 kWh, 624 kWh, and 512 kWh, respectively, in four regions, and the average ratio of solar power generation supply based on annual electric energy consumption was 6.3%. When applying the solar power generation system to the distributed data center, average annual energy saving was calculated as KRW 1,429,890, and the initial investment recovery period was evaluated as an average of 6.45 years.
