Generating “free” electricity with solar panels is attractive to many homeowners. However, there also many people who don’t like the sight of the blue panels on their roofs or in their gardens. That’s where fashion-sensitive Italians can help. Dyaqua is a new company that offers “invisible solar”. They have been able to add a top layer to regular stones, tiles or pieces of wood, which is opaque to the eye but includes photovoltaic cells. Now buildings can be updated to include renewable energy generation without losing their historic charm. And you can build your dream home.
