Coming Soon: Cheap light rooftop solar you can install yourself.

Fraunhofer is a big German research and development non-profit organization, with a couple of branches in the USA. They have been working with solar power for years, and last year held the record for making the world’s most efficient solar cell. Now they are looking to reinvent the way solar panels are installed.

They have redesigned the solar panel, mounting the photovoltaics on a light, flexible substrate, which has an adhesive back that essentially glues it to the roof. Because most building codes specify roof sheathing that is designed to allow for the weight of a second layer of shingles, these panels should be able to be installed without any engineering expenses or approvals because they weigh pretty much the same as shingles.
