ENLIGHT(TM) polyolefin-based films from Dow enable photovoltaic cells to work more efficiently at a lower cost, which extends the useful life of solar panels. Due to strong demand, Dow inaugurated a new ENLIGHT(TM) Photovoltaic Film production facility in Thailand in July, located close to fast growing panel production markets in the Asia Pacific region.
Dow introduced ENLIGHT(TM) Back Encapsulant Composite Films, a new “2-in-1” technology that serves as both a backsheet and back encapsulant layer for photovoltaic panels. The simplified structure eliminates delamination that can occur in today’s panels – helping to assure good panel performance and lower lifetime system costs.
Next generation ENLIGHT(TM) Polyolefin Encapsulant films were also introduced.These new films retain their advantage in moisture resistance, adhesion, and long term weathering performance with additional advances in extended electrical properties and optical transmission, leading to overall increased power generationwhen compared with more traditional EVA-based encapsulant films.
In addition, next-generation ENLIGHT Films now have five times better Potential Induced Degradation (PID) resistance compared with EVA films, showing only 15 – 20 percent loss in power after accelerated aging, versus a 90 percent loss for EVA under the same conditions.
In July, Dow completed construction of a new, state-of-the-art manufacturing facility for these breakthrough products in Map Ta Phut, Thailand, which has doubled global production capacity for ENLIGHT(TM) Films. The Map Ta Phut operation has been built with the latest energy efficiency techniques and also recently completed the installation of a 100 KW high efficiency solar panel system on the roof of its manufacturing plant.This system, which will be in place for approximately 25 years, will generate enough electricity to offset 4 million pounds of green house gases that would have been emitted by fossil fuels during that time, or the equivalent of planting 35 acres of trees.
The next phase of manufacturing expansion will take place at Dow’s integrated site in Schkopau, Germany. This facility will come on-stream in 2013, and will be Dow’s third manufacturing facility, behind Findlay, Ohio and Map Ta Phut.
“Dow is committed to finding new and innovative ways to leverage the capabilities of polyolefin technology for the most demanding needs of the growing solar industry,” said Brij Sinha, Associate Director of Global Strategic Marketing for Dow’s Photovoltaic business. “We are using what we learn from working closely with leading module manufacturers around the world to design new products and manufacturing systems to enable them to make panels with improved processing, enhanced performance and lower total lifetime systems costs. Leading industry reports underscore the demand for performance and cost improvements in photovoltaic materials. Dow’s polyolefin-based ENLIGHT(TM) Film Technology can help do just that.”
Dow’s Photovoltaic Business is one of seven Dow businesses that serve the needs of the solar value chain – through solar farms, rigid and flexible photovoltaic modules, concentrated solar power systems and solar shingles for residential use.
