The Increasing Importance of Smart Grialnverters

摘要

Distributed energy generation, particularly solar photovoltaic (PV), has evolved significantly during the past 10-15 years. As recently as 2000, off-grid PV installations for commercial and residential applications were 70 percent of the cumulative installed megawatts of PV systems. By 2010, off-grid had shrunk to 17 percent, while grid-connected centralized and distributed PV systems represented 15 and 68 percent of the installed PV, respectively.Forecasts indicate a continuation of this trend to meet state renewable portfolio standards (RPSs).
