Advanced Energy® Inverters installed at 35 MW Utility-scale California Solar Plant Project

Solaron 500 kW Inverters Selected by Cupertino Electric Based on Industry-Leading LCOE

FORT COLLINS, Colo., Nov 4, 2011—Advanced Energy Industries, Inc. (Nasdaq: AEIS), today announced that its Solaron® PV inverters have been installed at a 35-megawatt (MW) solar project located near Coalinga, California. The project was awarded to Advanced Energy (AE) by engineering and construction company Cupertino Electric, Inc. earlier this year to leverage the Solaron PV inverter's industry-leading energy-efficiency ratings and lowest Levelized Cost of Energy (LCOE).


"After considering all of the options, we found AE to be the best overall choice thanks to their combination of technical solution and price," said Meisa Kassis, project manager with Cupertino Electric, Inc. "Our successful delivery of this project to Pacific Gas and Electric Company (PG&E) was made possible by the contributions of subcontractors and suppliers like AE."

The 35 MW project consists of two sites owned by PG&E: Stroud, a 20 MW site, and Westside, a 15 MW site. The two sites are part of the first phase of a five-year PG&E plan to build 250 MW of solar power. The Stroud and Westside installations include 70 of AE's 500 kW Solaron® grid-tied PV inverters, which provide low voltage ride through (LVRT) and reactive power control.

"We are honored to be selected by Cupertino Electric to be a part of this utility-scale solar power plant," said Steve Levy, VP of sales and marketing at AE Solar Energy. "The Central Valley holds incredible potential as a source of clean energy for California and this project shows the major strides utilities are making in accelerating the deployment of renewable energy. By selecting industry-leading technology that delivers maximum energy harvest and industry-best LCOE from a bankable partner like AE, our customers benefit and are a key part of the equation to maximize return on investment."

The company's solar energy business is driving the adoption of solar by lowering the LCOE for its customers. By providing reliable, easy-to-install Solaron and PV Powered™ inverters and SiteGuard® whole-site O&M services, AE enables utility-scale, commercial, and residential solar project developers to maximize the lifetime value of their power plants. Customers count on AE as a trusted partner, leveraging 30 years of innovation leadership and global services infrastructure for optimum project performance.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
