Many light up at renting out apartment roofs for solar panels in Japan

According to The Asahi Shimbun, photovoltaic (solar) cells densely line the roofs of two apartment buildings in Yachiyo, Chiba Prefecture, generating as much as 13.5 kilowatts of power at each building.
That is enough to meet the energy needs of four-and-a-half ordinary households.
The apartment buildings were built last September by Daito Trust Construction Co. and an affiliated company covered the installation and maintenance costs of the solar cells.
Because of that, the owner--Chiyoko Fukuda, 63, who is eligible for the monthly rooftop rental fee of 15,000 yen (US$112)--said she is content with the contract.
“I am just leasing out the upper coverings,” said Fukuda. “I invest no money but can receive a small sum. If I ever get more land, I want to rent more.”
