AETI ISIS(TM) Installed in 1.1 MW California Solar Project

Projected to save the city more than $1 million in energy costs

HOUSTON, Dec. 3, 2012 -- American Electric

Technologies, Inc. (Nasdaq:AETI) a leading global provider of power
delivery solutions for the energy industry, announced today that it
supplied Siemens Industry, Inc. with a 1.0 megawatt (MW) Integrated
Solar Inversion Station (ISIS) as part of a Power Purchase Agreement
(PPA) with the City of Atwater, CA. The Siemens-owned and -operated
20-year solar project, which powered up in October, 2012, is projected
to save the city more than $1 million in energy costs. Contract terms
were not disclosed.

The 1.0 MW ISIS, along with bundled installation and commissioning
services, provided Siemens with a fully integrated product and service
offering to help meet their project timelines. With AETI's
capabilities, Siemens will enable the City of Atwater to reduce costs
and meet increased energy demands associated with their new wastewater
treatment plant adjacent to the solar project site. The complete solar
system will generate 2,221,738 kWh of clean renewable energy annually,
and realize significant greenhouse gas emissions savings.

AETI's ISIS platform is the world's first 1000V 1MW solar inverter
witness-tested to UL1741 by a nationally recognized test lab (NRTL),
TUV of North America. The ISIS system deployed at the Atwater site
incorporates an integrated DC master re-combiner, control power
transformer, and grid-tie transformer, and was installed by an AETI
services team with over 2GW of grid-tie projects to date.

"We are pleased to have been selected by Siemens for their solar
project in Atwater, California," said Kent Breaux, global director of
renewables, AETI. "Partnering with a reputable solar project developer
like Siemens allowed us to deliver the customer a superior level of
quality service while helping them reduce high energy costs and meet
renewable energy goals."

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
