SHANGHAI, Jan. 7, 2014 /PRNewswire/ -- Hanwha SolarOne Co., Ltd. (the
"Company", or "Hanwha SolarOne"), a top-10 global photovoltaic manufacturer of
high-quality, cost-competitive solar modules, today announced it has reached a
memorandum of understanding ("MOU") with OneRoof Energy, a complete solar
services provider, to supply up to 50 megawatts of Photovoltaic ("PV")
modules. Hanwha SolarOne and OneRoof Energy intend to enter a supply agreement
to establish a reliable supply of modules for OneRoof Energy, as well as to
work together to identify and develop new and next generation products for the
residential market that will enhance energy yield, improve bankability and
increase residual value, and engage with downstream suppliers to improve PV
system efficiencies and lower the levelized cost of energy to homeowners.

Mr. Min-Su Kim, President of Hanwha SolarOne commented, "OneRoof Energy is
well positioned in the burgeoning residential rooftop financing market in the
U.S. where in large markets like California, industry sources estimate about
three-fourths of all solar installations were the result of third-party
financing. Our high-quality, proven modules will play an important role in
meeting OneRoof Energy's performance and product warranty customer

"Hanwha SolarOne makes high-quality, reliable modules, but most importantly
they offer our customers peace of mind that the panel manufacturer will be
there to back the warranty for 12 years. The power of Hanwha is in their
ability to deliver on that promise," stated David Field, President and Chief
Executive Officer of OneRoof Energy.
