Development of photovoltaic modules integrated with roofing materials (heat insulated roof panel)
- Kaneka Corp., Osaka (Japan)
The authors have started to develop low cost photovoltaic modules integrated with roofing materials for wooden houses. They made a concept of the design for the modules using amorphous silicon solar cells and produced test modules that consist of untempered surface glass, solar cells, waterproof sheet, heat insulating materials and base frames. They have primarily tested the distributed pressure resistance as a building component. When applying a load from the front surface side of the modules, a 3.6 mm deflection at the center of the specimen under 300 kg/m{sup 2} load was observed, which is equivalent to a snowfall of 1.2 meters. As a result, they have finally confirmed that modules have enough structural strength to be used as a roof panel. They also tested the impact resistance of untempered surface glass by the testing method in JIS3212. In this test, cracks could not be seen from a height of 75 cm.
