  14. （3）－１　Project objectives Background Environmentally friendly photovoltaic power generation systems can provide nearly unlimited energy and require minimal, uncomplicated maintenance. Expanding photovoltaic power generation is essential for oil-alternative energy development. International Cooperative Demonstration Project Utilizing Photovoltaic Power Generation Systems To develop practical uses for PV power generation systems, it is necessary to enhance systems from the perspective of cost reductions and improved reliability through verification tests. International cooperative verification is expected to obtain data under host countries’ distinctive climatic and social systems that cannot be replicated in Japan. • NEDO conducts domestic research activities to resolve technical issues for the introduction of dispersed power sources such as PV power generation systems. • Overseas project implementation aims to contribute to host countries’ sustainable development.
