NEW YORK, Oct 5 (Reuters) - Dow Chemical Co (DOW.N: Quote, Profile, Research) said on Monday it would begin selling a new rooftop shingle next year that converts sunlight into electricity -- and could generate $5 billion in revenue by 2015 for the company.

The new solar shingles can be integrated into rooftops with standard asphalt shingles, Dow said, and will be introduced in 2010 before a wider roll-out in 2011.

"We're looking at this one product that could generate $5 billion in revenue by 2015 and $10 billion by 2020," Jane Palmieri, managing director of Dow Solar Solutions, told Reuters in an interview.

The shingle will use thin-film cells of copper indium gallium diselenide (CIGS), a photovoltaic material that typically is more efficient at turning sunlight into electricity than traditional polysilicon cells.

Dow is using CIGS cells that operate at higher than 10 percent efficiency, below the efficiencies for the top polysilicon cells -- but would cost 10 to 15 percent less on a per watt basis.   Continued...
