| New Dirt-Free Module  Kyocera Corporation is pleased to announce that the Solar Energy Operation is releasing the Dirt-Free Module, which more easily sheds airborne dust and dirt and thereby stays cleaner than traditional modules. The product is scheduled to be released in Japan in September. PV systems have been installed on flat-surface such as flat roofs and folded-plate roofs with lock seams, at a fixed angle of inclination, specifically around 30 degrees, to maximize possible sunlight received. Recently, more and more PV systems are mounted at a lower angle to enable installation of as many PV modules as possible on the entire roof or to improve the overall look. With this type of installation, the angle of inclination is about four to five degrees on flat roofs and is equivalent to that of the roof inclination on folded-plate roofs with lock seams.PV modules installed at a lower angle are more likely to accumulate dirt and dust, which prevent light from penetrating to the module, to thus generate electricity. Rain washes airborne dust off tilted PV modules. Flat-mounted PV modules gather more dust, and when it rains dirt puddles on the surface of each module. Kyocera has recently developed the Dirt-Free Module. This product has three hollows at each of the three positions on each of the four sides of the aluminum frame that surrounds of the PV module. These hollows serve as channels through which dirt and dust on the glass surface are easily carried off by rainwater. The hollows provided on the aluminum frame that surrounds the PV module enables dust and dirt that has accumulated on the glass surface of the module to be removed by rainwater. With these hollows, the module is less likely to be soiled or to have dust accumulated on its surface. The new module is especially suited to facilities with flat-surface roofs on which PV modules are mounted at low angles of inclination, such as factories, warehouses and office buildings. Kyocera will be adding the Dirt-Free Module to its standard lineup of solar power systems for flat roofs. Through the extensive sales channels owned by its sales subsidiary, Kyocera Solar Corporation, the Company will be active in proposing this new product to the housing market as well as to the industrial and public-sector market. write your comments about the article :: © 2005 Construction News :: home page |
