"If Musk’s claims prove true, this could be a real turning point in the evolution of solar power. The rooftop shingles he unveiled just a few weeks ago are something to behold: They’re made of textured glass and are virtually indistinguishable from high-end roofing products. They also transform light into power for your home and your electric car. "
While they are not cheap they are tough, light-weight and long-lasting. It looks a very promising product. Hopefully other companies will come out with competing products soon and such tiles will become available in Guyana in a few years. Being light-weight is important as it reduces shipping costs and is also better for the kind of houses built here.
