The One-of-a Kind Partner Program with Proven Success in Europe Brings U.S. Solar Installers a ‘One Stop’ Resource for Growing their Business

Scottsdale, Arizona – October 7, 2010 - Timely, with President Obama having solar panels installed on the White
House roof, supporting the rapid growth of the solar industry in a recession, CENTROSOLAR America introduces
CentroClub, a new suite of programs designed exclusively to support solar installers’ business in meeting the
growing demand for solar across the country.

Set to be introduced at booth # 4547 at the Solar Power International show in Los Angeles October 12th-14th, the
CentroClub Partner Program offers new and established solar installers and integrators across the country access to
year long support resources. The CentoClub Partner Program is available to both residential and commercial
installers and provides sales and marketing support, technical training, tailored financing programs, and Market
Development Funds (MDF) and its high-value engineering services.

“With the introduction of CentroClub, we now bring an unparalleled level of support to our growing network of
installers and trade professionals,” said CENTROSOLAR America CEO Deep Chakraborty. “The solar industry
now has tremendous momentum as solar is now a viable option for mainstream America. This program gives
installers the necessary tools they need to compete successfully and take part in this new renewable energy
marketplace that provides tremendous opportunity that are here to stay.”

What makes the CentroClub program particularly unique is that CENTROSOLAR America is already one of the
few PV manufacturers with a business that sells directly to installers with its own nationwide sales force, while
providing engineering services support and a national footprint for warehousing and distribution across the country.
With its recent introduction of the latest CentroPack®, CENTROSOLAR America’s complete, pre-packaged and
‘out-of-the-box’ rooftop installation system, the company now offers a complete, seamless suite of residential solar
installation products and support services with the introduction of the CentroClub Partner Program.

“This is the best of both worlds for installers. Not only can we deliver an entire line of best-of-class German engineered
pre-packaged rooftop installation systems with quick delivery to the job site, but they also gain access to
the support services they need for every aspect of their business—from proposal generation software to financing to
installation and access to our in-house lead generation resources,” added Chakraborty.”

Through the CentroClub marketing services for its partners, they gain a competitive edge in their local markets by
participating in cross promotions with CENTROSOLAR America’s marketing team, resource listings in
promotional materials and proposal templates for their prospective clients. In 2010, more than 200 installers and
tradesmen across the US participated in CentroSchool, CENTROSOLAR America’s national training program,
which has become a cornerstone program for CentroClub members.

While there is no cost to join CentroClub, partners can participate at two levels, Gold and Silver, depending upon
their sales volume. The Silver membership is available to start-up solar businesses with no sales commitment, while
providing access to wide range of CentroClub benefits.
