Harnessing and converting the idle power of sunlight is alluring for so many reasons.   Besides the often expensive upfront equipment and installation costs, solar power systems can generate clean electricity for years requiring little maintenance or operational attendance.   As the efficiency of solar cells continues to improve and production costs fall, unused rooftops around the world could soon be converted into electricity generating power-plants.

We’ve already seen attempts to create roofing materials that absorb or reflect sunlight depending on the season.   Now, an Italian company called Tegolasolare has developed a terracotta roof tile with integrated photo-voltaic cells.  The company claims a 40 square-meter roof can generate up to 3000 Watts of electricity in direct sunlight – which coupled with a moderately sized energy storage system could provide a significant portion of an average home’s energy requirements.  And although the roof attempts to maintain the visual appeal and durability often associated with terracotta, installation of the roofing tiles could be difficult.

“During construction or restructuring of the roof, suitable raceways must be provided to convey the connection wires between solar panels, and from the panels to the inverter or interface panel.” — Tegolasolare

No word on pricing, but if its competitive, sunny regions around the world where terracotta roofing is popular could be prime markets.
