SABIC Leads the Curve with First Polycarbonate BIPV Panels
With approximately 70 gigawatts (GW) of cumulative global installations, PV systems represent the third most important renewable energy source – after hydroelectric and wind power – in terms of capacity.
“The new Lexan BIPV panels show SABIC’s commitment to challenging the status quo to find better solutions and create practical innovations for customers in the building and construction industry,” said Jack Govers, general manager, Specialty Film & Sheet, Innovative Plastics. “Our collaboration with Solbian has created a technology that can transform conventional roofing and glazing systems and provide new choices for the integration of solar systems into building designs across the globe. We take pride in delivering the performance architects and builders expect when achieving their sustainability goals, and in powering their competitive advantage.”
“Our successful collaboration with SABIC has resulted in a very new, high-performance solution that will no doubt drive broader adoption of photovoltaics across many types of commercial and residential structures and geographies,”
Elegant Curves, Practical Performance
One of the top benefits of Lexan BIPV panels is design freedom. Compared to traditional BIPV materials, the SABIC panels can be easily cold bended on site to form graceful, curved roofing systems integrating daylighting and photovoltaic. By using semi-transparent Lexan BIPV panel modules designers can create unique day-lighting features in façade, roofing or skylight systems.
In addition, the new panels provide high performance, beginning with excellent thermal insulation and light management that are hallmarks of Lexan Thermoclear sheet. The new panels can reduce energy consumption by up to 17 percent vs. traditional high-return, double-pane glass glazing. They help to reduce cooling load and glare associated with large expanses of architectural glazing. This virtually unbreakable, ultraviolet-
Another important benefit of Lexan BIPV panels is light weight that can make them less expensive to transport and facilitates easy and fast assembly. Compared to heavy glass panels or standard PV panels, Lexan BIPV panels can deliver potential savings on installation time and costs. Also, the panels can be used with a lighter supporting steel framework than glass requires, which may reduce material and shipping costs.
Lexan BIPV panels are available in 10, 16, 20, 25 and 40 mm gauges, in rectangular and X wall configurations and include a color palette of clear, opal white, bronze, green, blue and gray.
High Demand for Green Building Materials
The drive to reduce energy consumption is one of the highest priorities in building and construction today. Based on average material costs, green building materials represented approximately $14.5 billion in cumulative spending through 2010, and are expected to reach nearly $120 billion by 2030.2 BIPV panels are increasingly incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with BIPV modules as well.
The new Lexan BIPV panels comply with the International Electrotechnical Commission (IEC) EN ISO/IEC 17025, EIC 61215 and IEC 61730-2 standard certifications and contribute to the Leadership in Energy and Environmental Design (LEED®) green building certification system. The new panels, which will be commercially available from SABIC in the second half of 2012, have already been installed at a SABIC manufacturing facility in Italy.
