（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.
