Project summary
Panahome-city Seishin-Minami PV project consists of 100 house compartments with PV rooftops of 3 kWp each. 31 houses have inclined roofs with mounted regular framed PV modules, while 69 houses have inclined roofs with PV roof tiles. In total 299 kWp (mulit-crystalline silicon) is installed by the Kyocera corporation.

Urban scale PV aspects
Panahome-city Seishin-Minami is a community located in the Seishin-Minami new-town developed by Kobe city and is far from 30 minutes from center of Kobe-city. The area is 18 000 m2 in total and consisted of 100 house compartments. PanaHome corporation, which is one of the biggest housing companies in Japan and is a main constituent of the PV community, is dealing with a eco-life house, named ‘El Solana’, pursuing the concept of ‘Energy creation’, ‘Energy conservation’ and ‘Safety’. The El Solana is equipped with PV system and ‘SAMURAI’ developed by Kyocera corporation is on the roof as PV modules. A concept of developing the area was ‘A human- and environment- friendly town’ and this was realized by developing the eco-life houses’ area.

Special PV project info
PV architecture and building integrationTo create a well-designed appearance of the houses and a harmonized streetscape as a community, a design of each house was given variety to color tone and configuration. And PV modules on the roofs were required to harmonize with the design. As well, a shape of roof was designed for 3kW PV modules.
Urban planning issuesSeishin-Minami new-town is developed as a new urban development project of Kobe city. As for a development of residential area by private sector, a competition was conducted and PanaHome corporation was one of the developers that the plan proposed was approved.
Economical and financial issuesA governmental subsidized program for residential PV systems was available for PV system installation. After starting operation, a net-metering has been applied and surplus electricity from the house is being traded between the inhabitant and the utility company, at the same price of electricity tariff for residentials.
PV ownershipBuilding owner: Inhabitant; PV owner: Inhabitant; PV energy user: Inhabitant
Tariffs and meteringNet-metering
Info on grid issuesThe electricity distribution line in the area was designed and constructed by the utility company (the Kansai Electric Power Company). As a countermeasure of electric power failure caused by the earthquake, a power-conditioner having a function of autonomy-operation mode was adopted for PV system.
Other infoBased on the concept, ‘Ecology & Safety’, all housed are equipped with a rain water storage tank and a home security system as well as PV system. In addition, some houses are all-electrified and equipped with a high-efficiency electric water heater, called “Eco-Cute”, and others were equipped a gas co-generation system, called “Eco-Will”.
