Installed in 2013, this 39-module system features LG 290-watt panels and Enphase 250 microinverters. To integrate the panels with the Spanish tile roof, we removed the tiles and laid down a composition roof. We then reinstalled tiles around the system, allowing the panels to lay almost flush with the surrounding tiles.
