From Case Study: Alys Beach, Fla., Custom HomeThe home’s solar electric (PV) system is installed at a slight south/west tilt on a flat roof section adjacent to the outdoor kitchen, enabling easy access to the panels and keeping them off the home’s sloped roof to maintain aesthetics. The BP Solar modules feature polycrystalline cell technology and 92% transmission through the glass top pane to capture more solar energy. The grid-tied Solaris XP inverter from Alpha efficiently converts DC power to AC and offers built-in battery backup and net-metering capability. The system delivers up to 4.8 kWh of free electricity, significantly offsetting energy costs. BP Solar: 866.277.6527. www.bp.com. Alpha: 360.647.2360. www.alpha.com.
