Evergreen Solar Showcases Solar Power at Deutsche Bank Championship

Solar installation will help offset power used during PGA TOUR Playoff event at
Deutsche Bank Championship at TPC Boston
MARLBORO & NORTON, Mass.--(Business Wire)--
Evergreen Solar, a manufacturer of STRING RIBBON solar power products with its
proprietary, low-cost silicon wafer manufacturing technology, today announced
that a solar power system using Evergreen Solar panels has been installed on the
grounds of the TPC Boston in Norton for the 2009 Deutsche Bank Championship, a
PGA TOUR Playoff event.

The goal of incorporating solar energy into the Deutsche Bank Championship is to
highlight the importance of solar energy and its potential to help meet the
nation's energy needs while addressing concerns about the environment and global
warming. The solar installation is part of the Deutsche Bank Championship`s
overall greening initiative through which, for the second consecutive year, the
tournament is the only carbon-neutral event on the PGA TOUR.

"We`re thrilled to be involved with the Deutsche Bank Championship and the PGA
TOUR on its biggest stage - the PGA TOUR Playoffs," said Dr. Terry Bailey,
Evergreen Solar`s senior vice president of marketing & sales. "We commend the
Deutsche Bank Championship for its commitment to being the greenest event on the
PGA TOUR and are proud to be able to contribute clean, solar energy to help make
that possible."

The solar system, which is housed between the ninth green and 10th tee box on
the TPC Boston course, demonstrates to the public a typical photovoltaic (PV)
system that produces enough energy to power the average American home. The
energy produced by the installation will be put back into the local power grid
to help offset some of the power used throughout the Championship.

"We take great pride in being the first and only carbon-neutral event on the PGA
TOUR," said Eric Baldwin, Deutsche Bank Championship Director. "We`re excited to
partner with Evergreen Solar in order to not only offset our power consumption
throughout Championship Week but also demonstrate the benefits of solar power."

All of the solar panels for the installation were donated by Evergreen Solar.
Evergreen panels deliver more electricity with less impact on the environment
including the smallest carbon footprint and quickest energy payback of any
silicon panel. Alteris Renewables, the Northeast`s leading installer for homes,
businesses and organizations, donated and oversaw the system design and
installation materials and services.
