Dow Chemical’s solar shingles will essentially take the place of regular asphalt shingles and can be used on the areas of a roof that gets the most sun. Even with the higher cost of the solar shingles themselves (and Dow hasn’t yet announced pricing), installation costs would be lower than with a traditional solar panel system. While you would still need an electrician to run the wires from the roof to an inverter and into the house, the shingles themselves are installed exactly the same as regular asphalt shingles and there would be no need for the specialized skills to install regular silicon solar panels.
Dow has been working with copper-indium-gallium-selenide (CIGS) solar cell maker Global Solar Energy to develop these shingles.
