摘要: Abstract Declining costs for solar photovoltaics (PV) and excitement about new technologies have led to speculation that self-sufficient PV/battery storage systems will soon become competitive with traditional electricity service. We compare a grid-tied residential system an off-grid solar-plus-battery at 1020 US locations, calculate three effects of “grid defection” each: the private net homeowner, change in generation costs, emissions. For average location, is almost double price grid-connected solar, associated higher has no emissions benefit.
