Dow Solar, a business unit of the Dow Chemical Co. of Midland, Mich., has been awarded a $12.8 million, three-year grant from the US Department of Energy’s SunShot initiative to fund a program that will reduce the cost of building-integrated photovoltaic (BIPV) solar products. The grant will help fund a $22.4 million program that brings together leaders from across the solar value chain to create solar technology that reduces total installation costs and provides reliable energy to residential customers. Dow Solar’s program will involve developing materials and designs to enable the integration of lightweight and robust BIPV shingles.
