It was the first solar power generation system installed by Habitat for Humanity Japan under its “Solar Home Recovery Project,” offering photovoltaic (PV) systems to victims of the tsunami, particularly those with disabilities.

The project takes advantage of Japan’s new feed-in tariff (FIT) incentive
