While some listeners might find it hard to fathom, the perceived unsightliness of rooftop solar panels can actually be a barrier to widespread adoption. There are homeowners associations and even municipalities from the suburbs of Dallas to Bordeaux, France, that restrict the endlessly renewable energy source that rooftop solar panels represent. But our guest today on Sea Change Radio, Oliver Koehler, is the CEO of a company called Suntegra that offers the perfect solution: solar panels that integrate into roof tiles. Koehler gives us a snapshot of his company, talks about Suntegra’s technology, and offers a glimpse of the competitive landscape. Then, we re-visit our discussion with Richard Lunt about transparent solar cells, another cutting-edge technology that can integrate with skylights and windows.
