The Korean government recently announced “Renewable Energy 3020 Policy” in order to increase the proportion of renewable energy generation to as much as 20% of total. To that end, the Korea Energy Agency will implement the photovoltaic system dissemination project for the roofs and parking lots of industrial complexes, thus contributing to achieving the goal of the government policy. This study applied conventional PV and recently developed L-PVTs systems to some industrial complexes and conducted energy analyses using the TRNSYS 18 simulation software package to draw energy production and economic effect of each installed system. The study method is as follows: First, the distribution and status of the national industrial parks were investigated. Second, a photovoltaic weather resource map was employed to investigate and compare the resources in the regions with industrial clusters. Third, industrial parks were selected, and their energy output was calculated by using the TRNSYS18 program and applying the PV and L-PVTs systems. Fourth, economic return was evaluated by calculating the payback period of each system. Supplying and installing L-PVTs in national industrial complexes is expected to increase the electric energy production by approximately 20% compared with PV installations. Furthermore, the L-PVTs also show excellent economic efficiency because the payback period of L-PVTs is 45% shorter than that of PV depending on the utilization method when electricity is produced using the produced thermal energy in conjunction with a small cogeneration system having an efficiency of approximately 45%.
