Roof-integrated PV System “Kubota’s Power-generating Roof: Ecolony”

Kubota Corp.
This is a roof-integrated power generation system employing thin-film silicon hybrid modules for solar cells, and achieved generating output of 37.5 W per cell. The system can be flexibly adapted to various shapes of roofs. The modules can incorporate not only Kubota’s roofing but also be combined with other competitive roofing. The system is expected to contribute to widespread use of the roof-integrated power generation system, which is not yet employed as standard equipment for dwelling houses.
Features of Equipment, System and Facilities
• “Hybrid silicon thin-film PV modules” are employed, for the first time in the world
In general, a roof-integrated PV system tends to invite temperature rise of module due to little clearance form roofing compared with a mounting type PV system. Besides, crystalline modules have a problem of lower generation output. However, “Ecolony” has solved this problem, by employing “hybrid silicon thin-film PV module,” which minimizes the generation efficiency decrease even at high temperatures in summer.
• Two-cell units that can be adapted to various shapes of roofs when installed
Since the voltage per cell could be successfully enhanced, two-cell units can be installed.
