Solarcentury is launching the new C21e solar electric plain roof tile, responding to demand for more products for roofs. The advantage of the C21e is that it can easily be integrated into traditional small format tile roofs. The company first launched the C21e roof tile in 2005, going on to win the Queen’s award. The tile is 47W and 54 tiles for a typical 2.5kWp system and this system is able to replace on average 200 tiles and thus, uses a lot less space on the roof.
