Reuters: Dow Chemical delays launch of solar shingle

Dow's shingles will use copper indium gallium diselenide solar modules, or CIGS, made by privately held Global Solar Energy Inc. Global Solar was not immediately available to comment.

CIGS cells typically are less efficient at turning sunlight into electricity than traditional polysilicon cells.

Still, it should to be more cost-effective at these quantities and a good retrofit for existing homeowners. Made in U.S.A.

Hopeful, KF
