KYOCERA Installs Solar Power Generating Systems
at Kyoto Prefectural Government Office Buildings

Contributing to environmental protection in the birthplace of the Kyoto Protocol

March 24, 2009
Kyocera Corporation (President: Makoto Kawamura) announced that it has installed solar power generating systems with a total output of 40 kW at two Kyoto prefectural government office buildings. The buildings symbolize the prefecture of Kyoto, a place which is known around the world as the location where the international environmental treaty, the Kyoto Protocol, was adopted.

In this project, two 20 kW solar power generating systems — consisting of 112 modules each — were installed at the government office building #2 and the parliamentary building, resulting in a total output of 40 kW (224 modules). The electricity generated by the systems is used for lighting and other electrical needs in the government office buildings. The systems will also contribute to the reduction of CO2 emissions.

Outline of the Systems

Location Kyoto prefectural government office building #2 and
parliamentary building, in Kyoto City
Total Installation Area Approx. 288m² (approx. 144m² × 2 locations)
Total Output 40 kW (20 kW system × 2 locations)
System Configuration Total 224 solar panels (Output 178.6W/module, 112 modules × 2 locations), power conditioners, connection boxes, power generation display panels, etc.
Start of Operation March 24, 2009
Projected Power Generation Approx. 35,491 kWh/year


Features

The solar power generating systems installed at the Kyoto prefectural government office buildings employ the original Kyocera high efficiency solar cells, d.Blue, and a Dirt-Free design feature that is ideal for solar modules installed at a low angle. The hollow grooves on the aluminum frame that surrounds the solar module allow dust and dirt that have accumulated on the glass surface of the module to be removed by rainwater. Theses hollow grooves keep the module free from dust and dirt that would typically accumulate on the surface even when these modules are installed at a low angle to maximize installation area and provide optimal aesthetic appearance.

Moreover, for design and installation, Kyocera has made use of the engineering technology of the Kyocera Group, which has achieved the top market share in Japan in terms of the total number and capacity of solar power generating systems installed for public and industrial uses.*

The Kyoto prefectural government is also implementing rooftop gardening on the east side of the rooftop of government office building #2 (Kyo-Terrace), and this area is open to the public as a way to encourage participation by residents. The solar power generating system installed on the west side of the same rooftop can be seen from close up near the garden. Also, display monitor panels* were installed in several places (the rooftop of the building #2, the entrance lobby on the southern side of government office building #1, and the lobby of the parliamentary building) so as to let residents know the status of power generation and how the system works.
* Display monitors are used in government office building #1 and the parliamentary building.

The Kyoto Declaration on the Global Environment is posted in the Kyoto prefectural government office building, marking Kyoto as the location where the Kyoto Protocol was adopted. The Kyoto Protocol is widely regarded as a historic first-step toward protecting the future of the global environment and humankind.

Headquartered in Kyoto — a symbolic location for global environmental protection — Kyocera, from its position as a manufacturer, will continue to contribute to solving environmental issues such as global warming by promoting the spread of solar power generating systems.
