Granite Chief and SolFocus Bring CPV to Mexico
GRANITE CHIEF and SolFocus have announced their partnership to bring solar power plants to Mexico. These power plants will be based on Concentrator Photovoltaic (CPV) technology, which provides high efficiency in converting sunlight to electricity. As a local Mexican renewable energy developer, Granite Chief will lead the deployment of projects in various market sectors, and SolFocus will provide the technology to deliver dependable, low cost solar energy to its customers.
As its first project of scale, Granite Chief will install a 1 megawatt (MW) CPV solar farm in Apaseo el Grande, Guanajuato. This solar farm will incorporate 113 SolFocus SF-1100S CPV systems, and will provide power to Granite Chief’s factory. Construction on the plant will begin in late 2011, with completion early next year. “This power plant alone will provide about a 25 percent increase in the operational capacity of solar energy in Mexico,” said Granite Chief CEO Fernando Arriaga.
“Installation of this plant at our own factory provides an excellent return to the company in reduced energy costs, and
demonstration project that they donated to The Universidad Nacional Autónoma de México (UNAM). This donation includes an installation of a SolFocus SF- 1100S CPV system to the University, which in addition to providing power to some of thecampus lighting, will more importantly provide the opportunity for hands-on experience with this advanced PV technology. UNAM, home to 300,000 students, is a renowned technical institution. “We are very grateful to SolFocus and Granite Chief for this significant donation,” said Maestro Gonzalo Guerrero, faculty director of engineering at UNAM.
also showcases the potential for similar plants across Mexico. With the excellent generation capability of SolFocus CPV, we can provide customers a dependable electricity supply with predictable energy prices.” He added, “We anticipate deploying up to 20 MW of SolFocus CPV over the next 24 months - these projects are just the start for solar energy in our country.”
At the Green Expo in Mexico City (Sept. 28, 2011) Granite Chief also announced a
“We are confident that our students can make the most out of this innovative solar system in order to make Mexico more competitive in solar energy technology education, and provide clean energy to our country. “As the largest CPV installation in Mexico, this is a milestone project for the country,” said SolFocus CEO Mark Crowley. “SolFocus has been operating smaller solar projects in Mexico for over a year. We are pleased to now be working with Granite Chief in bringing efficient and resource-friendly solar technology to Mexico.”
WACKER expands polysilicon production
WACKER CHEMIE AG has begun producing hyperpure polycrystalline silicon at its Nünchritz site, the Munich- based Group announced today. First deposition reactors at the new production complex have already ramped up production of high-quality polysilicon for sale. The full nominal capacity of some 15,000 metric tons annually is expected to be operational in the second quarter of 2012. The start of production is three months earlier than WACKER’s very ambitious original timetable. All in all, WACKER has invested about ?900 million in these new production facilities — creating more than 500 new jobs as a result.
Rudolf Staudigl, President and CEO of Wacker Chemie AG, explained to
journalists in Nünchritz on Monday: “This expansion of capacity is instrumental to continue meeting our customers’ strong demand for top-quality and highly efficient solar-grade polysilicon in the years to come. Our extensive technological expertise as well as our highly experienced teams of engineers and
production staff allowed us to initiate production sooner than expected.”
As previously announced, WACKER decided in March of this year to rise production output at the Nünchritz site from an initial target of 10,000 metric tons to 15,000 metric tons per year. This rise in
capacity will be achieved by taking debottlenecking measures within the integrated production network at the site. WACKER’s entire polysilicon output, including that from Nünchritz, is almost completely under contract until the end of 2015.
The new production complex utilizes highly integrated material flows. This means that manufacturing by-products are reprocessed and then reused as starting materials in the value chain. Doing so lowers costs while conserving resources, and, as a consequence, sharpens WACKER’s competitive edge in polysilicon production.
