PowerGlaz® BIPV Warranty
Bespoke glass/glass BIPV modules are covered by a limited warranty which guarantees 90% of original rated power output for ten years. The 'original rated output' is that detailed on our 'flash test' report and supplied to the customer at the time of manufacture. |
Biulding Integrated Photovoltaic (BIPV) is the fastest growing sector of the PV market. The principle of BIPV is that PV panels (or modules) are incorporated into the building envelope substituting standard glass and other cladding materials with glass/glass laminates encapsulating Photovoltaic cells within. The modules are then incorporated into the building facade or roof where they generate electricity at the 'point of use' thereby maximising energy efficiency by eliminating transmission losses incurred when electricity is supplied via the national grid. PowerGlaz® BIPV can be integrated into vertical glazing, pitched glazing to canopies or walkways, and glazed roofs such as atria. It can be single or double glazed, and will fit easily into most proprietary glazing systems.
The cells are laminated between two layers of glass using an interlayer which retains the cells in position and also bonds the glass together. The glass is toughened or heat strengthened or possibly a combination of both. The glass may be 'heat soak tested' to help reduce the risk of spontaneous breakage. All glass processing is carried out 'in house' by Romag. The outer leaf of the laminate is 'low iron' glass, which improves light transmission, and therefore maximises the efficiency of the cells. The inner leaf of glass can be of virtually any glass type; for example it could be tinted, decorative or screen-printed to a specific design. The finished laminate can be double-glazed, or if it is to be fitted into a structural glazing system, a carrier frame can be bonded to the unit. Double glazing and structural bonding are also carried out by Romag.
On double glazed units connections exit from the edges of the unit, but single glazed modules offer the choice of either surface mounted or edge mounted connectors. The choice is largely dependent on the type of glazing system or aesthetic requirements.
