Can household solar photovoltaics provide a primary source of low-emission power? http://bravenewclimate.com/2013/04/01/household-pv-primary-le-power/#more-6096 "PV’s greatest strength lies in being embedded within the low voltage distribution network as a supplementary power source, where it can potentially provide valuable network support, but will require electricity market reform along with a substantial decline in lifetime battery costs. The conclusion is that the short-run tactical response of the expansion of PV without storage works against a long-run strategic approach to deep emission cuts, which will ultimately require the successful adoption of one or more of the candidate low-emission baseload technologies."
