The Dow Chemical Company and
announced that the Dow Powerhouse
Solar Shingle is the first residential
solar roofing shingle with an
integrated connection system to receive
UL's safety certification.
Underwriters Laboratories is an independent
product safety certification
organisation that has been testing products
and writing standards for safety for
more than a century. UL evaluates more
than 19,000 types of products, components,
materials and systems from more
than 66,000 manufacturers each year.
Unveiled in October 2009, the Dow Powerhouse
Solar Shingle is a groundbreaking
photovoltaic solar panel in the form of a solar
roofing shingle that can be integrated into
rooftops with standard asphalt shingle
materials. It reduces installation time and
complexity using a revolutionary system
design that eliminates on-roof wiring, minimises
through-roof penetrations, and
allows the product to be installed in the
same manner as a standard roofing shingle.
"The receipt of UL safety certification represents
the successful completion of a rigorous
and comprehensive multi-test process
for the Dow Powerhouse Solar Shingles,"
said Dow Solar Vice President Jane
Palmieri. "This is another important milestone
towards the planned 2011 commercialisation
of Dow's solar shingles, and represents
a crucial third-party validation of
the safety of this product. We are dedicated
to making solar easy for homeowners,
builders, and roofing contractors."
The Dow Powerhouse Solar Shingle from
Dow Solar Solutions integrates low-cost,
thin-film CIGS (Copper Indium Gallium
deSelenide) photovoltaic cells into a proprietary
roofing shingle design, which represents
a multi-functional solar energy generating
roofing product. The innovative
product design reduces installation costs
because the conventional roofing shingles
and solar generating shingles are installed
simultaneously by roofing contractors.
DSS expects an enthusiastic response
from roofing contractors since no specialised
skills or knowledge of solar array
installations is required. Its advantages
include affordability and lower system
cost, improved aesthetics, easier installation
and long-lasting performance.
The solar shingle systems were made
available in limited quantities in mid-2010
and projected to be more widely available
in 2011, putting the power of solar electricity
generation directly and conveniently in
the hands of homeowners.
