Twenty-three thousand square feet – that’s about half a football field, from goal line to 50-yard line and sideline to sideline. That’s also the size of the single-structure, thin-film photovoltaic rooftop system Dupont has installed at a plant in China through its Dupont Apollo subsidiary and partner China Everbright. The companies said the 1.3-megawatt (MW) system is the largest of its kind ever installed in China.
The project is something of a case of Dupont putting its money where its mouth is: Dupont Apollo is a soup-to-nuts thin-film photovoltaic module manufacturer and system solution provider, doing everything from project development to system design and engineering to material preparation, construction and installation.
The project in the Guangming New District, Shenzhen, began in July and includes 13,000 high-performance amorphous silicon (a-Si) thin-film photovoltaic modules made by DuPont Apollo. Dupont said the system delivers stable production even in low-light conditions and will provide around 1.5 million kilowatt hours (kWh) of electricity per year for 25 years.
Earlier this year, we reported on GE’s big move into thin-film solar. But whereas Dupont is working with amorphous silicon, GE chose to go the cadmium telluride route.
