ESA has contracts for more than 91 Megawatts (MW) of solar energy for 2012.

Lake Mary, Fl., February 22, 2012 - ESA Renewables (ESA), a leading turnkey solar solutions provider, recently announced its partnership with Advanced Energy Industries, Inc. (Nasdaq: AEIS). ESA has utilized AE Solar Energy's Solaron® and PV Powered™ inverters for all of its installations completed to date. Having recently been factory authorized, ESA is now certified to install and service any AE inverter operating on a solar energy generating power plant. ESA is the only company outside of AE to be a factory authorized service provider on their inverters.

"We are pleased with our decision to add AE Solar Energy as a preferred supplier," said Jeffrey Burkett, president of ESA Renewables. "Our engineers and technicians have successfully completed the factory training and are fully factory authorized and qualified to install and service these solar products."

ESA currently has numerous projects slated for commissioning in 2012, which amount to more than 91 MWs of solar energy generation. These solar farms are in various stages of completion, ranging from early development to construction. All are located in the United States, including eight projects in ESA's home state of Florida.

AE Solar Energy's utility-scale and commercial inverters were selected based on the company's reputation for lowest levelized cost of energy (LCOE), and different but complimentary product lines, which allow ESA to match the AE inverter best suited for each project's specific needs. Additionally, the company's inverter line offers a wide array of power levels, ranging from 35kW inverter building blocks to 2 MW integrated skids for optimal stringing and design flexibility to meet the demands of utility-scale, multi-megawatt PV projects.

"AE Solar Energy is pleased to be the preferred inverter supplier for ESA, and to have ESA as a certified factory authorized service provider," said Steve Levy, vice president of sales & marketing for AE Solar Energy. "The FAS program allows our service programs to grow quantitatively as well as competitively in regions where the power of our two companies are properly leveraged. As our business continues to grow we value the relationships with partners like ESA Renewables that further supports AE's commitment to supplying the market with proven inverter technologies that provide maximum return on investment."

ESA Renewables scope of work includes project development, financing, design and engineering construction, commissioning, monitoring, operation and maintenance through the life cycle of each install.
