The US Department of Energy's National Renewable Energy Laboratory has officially certified an aperture efficiency of 17.1% for a solar cell fabricated using Nanosolar's non-vacuum, flexible foil technology. The tests were carried out on September 1 under standard test conditions of 1000W/m2 at 25°C.
Dow Chemical said it will make the commercial introduction of its Powerhouse solar roofing shingle to U.S. markets this month. The company plans a rolling launch into markets from California to the East Coast that will continue through 2012, starting with the debut program in Colorado in October.
Although better known as one of the world's largest suppliers of oil, Saudi Arabia continues to join the solar age with the inauguration of one of its first larger-scale photovoltaic power plants on October 1. The facility, a 500KW system comprised of Solar Frontier CI(G)S thin-film modules, is located on Farasan Island and was installed by the Saudi Electricity Co. and Solar Frontier's parent company, Showa Shell Sekiyu (which is partially owned by the Saudi Arabian Oil Co.).
Although the financial costs remain unknown, an agreement has been reached over conservation issues arising from the 550MW Topaz Solar Farm project that First Solar is developing in San Luis Obispo County, California. A lawsuit against the project started by North County Watch and Carrizo Commons is expected to be dropped.
Having used Solyndra’s modules on a majority of its solar rooftop projects, EPC firm, Orion Energy Systems continues to champion the Chapter 11 firm’s technology and remains optimistic Solyndra could still emerge from the bankruptcy proceedings. Though its shares have fallen since Solyndra’s collapse, Orion Energy Systems claimed that it did not expect its business to be ‘adversely impacted.’
Constellation Energy has started to construct a 16.1MW solar installation in Emmitsburg, Maryland as part of the state’s Generating Clean Horizon’s initiative. The US$60 million facility will be financed, owned and operated by Constellation Energy with Maryland’s Department of General Services and the University System of Maryland purchasing the produced electricity under a 20-year PPA.
Continuing to build its project pipeline, First Solar has been awarded the engineering, procurement and construction (EPC) contract for a 130MW solar park to be built in Imperial County, California. Tenaska Solar Ventures, the solar energy affiliate of independent utility company Tenaska, will operate the park and has a 25-year power-purchase agreement (PPA) with San Diego Gas & Electric (SDG&E), which was announced in March 2011.
Sopogy’s Concentrating Solar Collectors have received OG-100 classification from the Solar Rating and Certification Corporation (SRCC). The certification qualifies Sopogy’s collectors for the solar programmes of a number of US states and validates the performance of Sopogy’s collector technology. The SRCC is the US’s independent accreditor for solar thermal products and Sopogy’s MicroCSP collector passed all of the third-party laboratory and outdoor tests; it was awarded the OG-100 certification after meeting all durability, safety and thermal performance requirements.
Softening end-market demand and production overcapacity have led to a significant decline in new PV equipment bookings in the second quarter of 2011, according to SEMI’s latest version of its ‘Worldwide Photovoltaic Equipment Market Statistics Report.’ Equipment billings reached US$2.03 billion for the quarter ended on June 30, 2011, an increase of 17% quarter-over-quarter, after declining 19% in the first quarter. However, bookings, a leading indicator were down 18%, compared with the previous quarter to US$1.79 billion. SEMI said that the book-to-bill ratio dipped below parity to 0.88 for the first time in the past six quarters.
