The British firm, Solaris Products Ltd., has chosen DuPont Tefzel T2 EFTE film as a substitute for glass in a lamination process to produce components for low-power photovoltaic systems. According to DuPont, Tefzel, which is used as the top layer of the module, brings a very high level of light transmittance in the operating frequency range of the solar cells. The manufacturer claims it is lighter and less fragile than glass and shows very little degradation over a long period of time. It is also said to offer excellent mechanical strength and reliability. The unbreakable solar panels can, adds DuPont, be combined with electronic components to provide roof-mounted ventilation for motor coaches, mobile shops, trucks, ambulances and fire engines. In fixed applications, they can be fitted to security posts, conservatories, warehouses and other types of building.
