Japanese rooftop PV-system to provide clean energy for 300 households

Joint venture juwi Shizen Energy has connected its first rooftop PV-system to the grid in Japan.

Consisting of 4,088 solar modules, the rooftop photovoltaic system in Kumamoto on the Japanese island of Kyushu took around four weeks of construction work to realise.

The photovoltaic plant, now in operation, was developed and constructed jointly by the juwi group and Shizen Energy with a total capacity of around one megawatt. Per year, the rooftop system produces approximately 1mn KWh of clean electricity - enough to power around 300 Japanese households.

The joint venture juwi Shizen Energy was formed at the beginning of the year by juwi group and Shizen Energy.

The installation is the company's first rooftop photovoltaic system and is installed on the roof of a warehouse that stores wheat and rice flour.

“However, it is not our first photovoltaic installation over here. Mid December 2012 we connected a free-field photovoltaic system to the grid,” said Masaya Hasegawa, Managing Director and founder of Shizen Energy and Representative Director of juwi Shizen Energy.

Amiram Roth-Deblon, juwi Regional Director Asia Pacific and Representative Director of juwi Shizen Energy, considers rooftop photovoltaic systems as an essential part of the energy revolution in Japan.

“The potential in Japan is huge,” he said. “There are millions of roofs that could be used for solar energy. This would contribute considerably to covering the energy demand of the Japanese people and industry.”
