Integrating Thin PV Amphorous Laminates Into Various Metal Roofing Profiles...

5. Module Design and Installation Examples

5-2 Stepped Roof (power output = 64 Wp/m2)

5-3 Flat Roof (power output=52Wp/m2)

5-1 Batten Seam Roof (power output=54Wp/m2)

Photo shows the installation on the roof of PLEA Press Center in Kusiro, Japan. Good harmony with standard metal stepped roof element without PV which is sheathed together.

Simple in both configuration and installation. Easy to inspect and replace a module after installation. PV module could work as heat collector too.

Easy installation can be done just by snap in the module to C channel member. Easy to inspect and replace a module after installation. Maximum module length is 5.4m. (This is what Kristina & Simon Cope have on the roof of their place in Meadowbank, Auckland)

Fig. 7 Flat Roof

5-5 Carport (prototype; power output=53Wp/m2)

5-4 Highway Soundproof Wall (prototype; power output=62Wp/m2)

PV panel is installed on the roof of commercially available carport. Quite simple installation: acrylic roof plate w simply replaced by PV panel with the dimension of 1300 x 840 mm. The radius of the panel is 3200 mm. The evaluation is in progress by NEDO (New Energy And Industrial Technology Development Organisation.

Fig 8 (top) shows the standard highway soundproof wall in Japan. PV modules are fixed by three different methods using dual surfae adhesive tape or screw or blind ribet. The evaluation is in progress by NEDO (New Energy And Industrail Technology Development Organisation) in Japan.
Fig 8 (bottom) shows another type of installation. 4m long PV panel is bent into triangle shape and screwed down to the top of soundproof wall.

5-7 Heat Collector Hybrid (prototype; power output=52Wp/m2)

5-6 Slide-In Type (prototype; power output=62Wp/m2)

PV module is placed in the heat collctor bx. PV module is bent into step shape in order to enhance heat transmissivity. Measurment of PV power output and heat collection s unerway on the roof of PLEA Press Center in Kusiro, Japan.

PV panels is installed just by sliding i C channel and by sliding fastener member in C channel. Time saving installation become more advantageous as the scale of PV array becomes large like PV power statio. Panel can be replaced easily.

6. Concluding Remarks

Fig. 9 Integration WIth Air Heat Collector (prototype)

Fig. 10 Slide In Type (prototype)

The amorphous silicon photovoltaic cell integrated roofing module was introduced. It has shown how easily this PV module can be integrated into an architecturally designed building thanks to the high compatibility with existing metal roof elements. Is is expected that this moduls would open a new metal roof age. To view an example one of these Canon solar PV roofing profiles in use in Auckland, New Zealand then contact Kristina and Simon Cope at the Solar Energy House today.
