With a grant for the Department of Energy's SunShot Initiative, the IEE SunShot Plug-and-Play team, in collaboration with Fraunhofer U.S.A.'s Center for Sustainable Energy and 12 other partners, is working to develop a cost effective market-ready plug-and-play residential rooftop solar system. While the average installed price of solar has more than halved since 2010 to $3/watt (W), the Department of Energy's SunShot Initiative aims to halve that cost again, targeting $1.50/W installed cost for residential PV systems to make solar energy a truly viable option for the average American home. The SunShot Plug-and-Play project aims to make the $1.50/W target a reality within three years. Because it is designed to be easier and safer to install, much like plugging in an appliance, and will automatically connect to the local utility through smart microelectronic devices, the plug-and-play system is expected to dramatically reduce the installation, inspection, and permitting costs for small residential PV. The IEE SunShot Plug-and-Play team has conducted comprehensive research into the codes and standards (structural, electrical, and procedural) governing residential rooftop solar installations in the United States. It has identified various regulatory barriers to the Plug-and-Play concept, and continues to identify both technical and regulatory solutions to those barriers. The team will also help to develop a voluntary industry standard and advise the wider team on regulatory and policy concerns arising throughout the project.
