~ Companies Join Forces to Install Solar Canopies and Rooftop Solar Arrays at Four Phoenix Area YMCA Branches ~

Scottsdale, AZ - December 20, 2011-Today, Centrosolar America, a national

solar energy manufacturing and services company, headquartered in
Scottsdale, AZ and Scout Solar, LLC, a Tempe, Arizona-based solar installer,
announce plans to activate solar PV projects at four 'Valley of the Sun
YMCA' branches. The solar arrays will be installed at YMCA branches in the
Tempe, Chris-Town, Ahwatukee, and Scottsdale/Paradise Valley communities.

With more than 1,500 Centrosolar America solar panels mounted on rooftops
and shade canopies, the combined solar power systems at the four locations
will generate more than 612,000 kilowatt-hours (kWh) of electricity annually
- an amount equal to the energy required to power 48 Arizona homes for one

"The YMCA's commitment to sustainability includes finding more ways to
promote the use of alternative energy. Utilizing the available space on our
shaded canopies and rooftops for the installation of solar panels was an
easy decision for us", said George Scobas, President and CEO of the Valley
of the Sun YMCA.

The Tempe branch will offset 21% of its energy costs with a 96.6 kWh shade
canopy solar system. The Chris-Town location will offset 24% of its costs
with a 98.7 kWh rooftop system. The Ahwatukee branch will offset 19% of its
energy costs with a 98.7 kWh shade canopy. And, the Scottsdale/Paradise
Valley branch will offset 12.5% of its energy costs with a rooftop solar
system. All four project installations are planned for completion by March

The systems are being installed and financed by Scout Solar, who will also
own and operate the systems and hold the rebates that are generated through
the Arizona state solar rebate program.

"There were no out-of-pocket costs for the Valley of the Sun YMCA for this
installation, "said Scout Solar Project Administrator, Michael Norris. They
will make a set monthly lease payment on the system, an amount far less than
what their savings on electricity will be. And they are protected from
future spikes in energy prices with this arrangement."
Bringing together best-in-class project partners, Scout Solar teamed with
Centrosolar to provide the solar equipment, Solar Energy Group for system
design, Wang Electric on the electrical installation and Skyline Steel to
construct the shade canopies and racking.
All the solar projects will be equipped with Centrosolar America E-Series

"Our E-Series panels utilize polycrystalline high-efficiency silicon cells
in an optimal configuration to generate higher power output per module. This
PV module configuration also meets the highest industry standards for
resisting intense heat as is typical in the Arizona climate," said
Centrosolar Director of Sales, Chris Wood. Centrosolar America, a wholly
owned subsidiary of Centrosolar Group AG in Munich, Germany, is one of the
leading solar distributors nationally as well as in the Arizona market.
