The Australian domestic photovoltaic adoption rates are the highest in the world, and this leads to overvoltage cut-out of many photovoltaic systems. This is a looming political problem as the PV system owners are not generally aware of this network constraint on their solar investment. This paper offers a policy process to start addressing the overvoltage problem. We use our econometric modelling of Australian PV adoption data. This modelling included spatial and ARIMA analysis of the 1.6M domestic solar installation decisions over the past 11 years. Measures of consumer response may be an effective input into policy development to reduce PV driven overvoltage problems, and reduce the impact of solar on the distribution grid.
