San Francisco, August 24, 2011 — California-based SunPeak Solar selected Suntech Power Holdings to supply 28.7 MW of solar panels for a 23 MW solar power plant in Niland, California.
SunPeak Solar's unit, Imperial Valley Solar Co., will oversee the project's construction including the installation of about 100,000 units of Suntech's 285/290W Vd-Series modules with advanced SuperPoly silicon processing technology.
The SuperPoly technology produces silicon ingots and wafers using modified multicrystalline silicon casting equipment that improves module performance by up to 10 percent.
The 72-cell Vd-Series module comes with Suntech's 25-year power output warranty —including 0/+5 percent positive power tolerance — that warrants 6.7 percent more solar power than the standard industry warranty. The product meets UL1703, IEC 61215, and IEC 61730 standards.
Constructed on a 123-acre lot located adjacent to the Imperial Irrigation District's Niland electric substation and natural gas turbine facilities, the solar power plant will generate enough energy to power about 14,000 homes within the utility's service area in Imperial County and parts of Riverside and San Diego counties.
The project will support IID's plan to comply with California's renewable portfolio standard, which requires electricity service providers to meet 33 percent of retail electricity sales with renewable sources by the end of 2020.
The solar power plant will also help IID meet daily peak electricity demands, as last year IID reached its highest peak demand ever of 1,004 MW. The solar project will potentially provide for about 2.29 percent of the utility's peak demand, supplying decades of clean electricity primarily during peak demand hours.
