Valley of the Sun YMCA to Activate 1.6 Megawatt (MW) Multi-Facility Solar Program Across 16 Arizona Y-Locations

~Local Officials Join Valley of the Sun YMCA, Scout Solar, and Centrosolar America for Ribbon Cutting Dedication in Scottsdale, Arizona~

Scottsdale, AZ-March 23, 2012-Today, the Valley of the Sun YMCA, Scout

Solar, LLC, Centrosolar America, and the City of Scottsdale celebrated the
deployment of 66.55 kilowatts of solar power as part of a 1.6 MW, multi-YMCA
project that promises to generate 10 to 80 percent of each facility's
electrical consumption over the next 20 years, depending on the location.

"We could not be more excited to activate a new era of sustainability for
the YMCA throughout Arizona," said George Scobas, President and CEO of the
Sun YMCA. "Our partnership with Scout Solar and Centrosolar will
substantially reduce our energy costs, so that we are able to continue our
standard of bringing excellent, affordable programs to our local
communities," said Scobas.

The ribbon cutting ceremony, held at the Scottsdale Valley of the Sun YMCA
branch, joined Scottsdale Mayor Jim Lane with local business leaders to
celebrate Arizona's oldest non-profit organization's commitment to solar
generated energy.

"I applaud the YMCA's commitment to alternative energy. By committing to
solar power, they not only demonstrate sustainability to the children and
families they serve, they also extend the power of every dollar. A project
like this means that the community will be better served, and that's what
matters most," said Scottsdale Mayor Jim Lane.

The project will include more than 6,200 solar modules, mostly coming from
Centrosolar America, mounted on rooftops and shade canopies across 16 Valley
of the Sun YMCA facilities in Arizona and will generate more than 2,700,000
kilowatt-hours (kWh) of electricity annually when fully completed at the end
of the summer.

Solar has already been installed at six locations and will be in place at
the majority of YMCA facilities in the state when the projects are all
completed, including: Ahwatukee, Chris-Town, Chandler/Gilbert, Desert
Foothills, East Valley, Glendale/Peoria, Goodyear, Maryvale
Scottsdale/Paradise Valley, South Mountain, Tempe, and the main Lincoln
Family Downtown YMCA. It will also include Chauncey Ranch, near Mayer, Camp
Sky-Y near Prescott and the Flagstaff branch in northern Arizona.

Scout Solar is installing the solar systems with no out of pocket costs for
the Valley of the Sun YMCA. Scout Solar, along with a group of private
investors, will also own and operate the systems. The project was made
possible, in part, by solar incentives from SRP and APS.

"Through this solar installation, the YMCA is planning for the future by
reducing electricity costs and locking in consistent, long-term savings,"
said Scout Solar Project Administrator, Michael Norris.

Bringing together best-in-class project partners, Scout Solar teamed with
Centrosolar America and other suppliers who provided the solar modules and
system components, with Solar Energy Group for system design, Wang Electric
on the electrical installation and Skyline Steel to construct the shade
canopies and racking.

"Thirteen of the projects will be equipped with our E-Series panels that
utilize polycrystalline high-efficiency silicon cells 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.
