Abstract
A Model for the Estimation of Residential Rooftop PV Capacity
Highlights
Introduction and backgroundAround one in four households in Australia have installed rooftop photovoltaic (PV) capacity and market penetration is growing at the rate of about 1,500 MW per year
It is not possible to estimate the effect of rooftop PV on electricity networks without knowing the amount of PV that is exported to the grid
This article describes a novel model developed for the purpose of estimating an individual household’s rooftop PV capacity, using data on the household’s estimated annual rooftop PV exports to the grid and its volume of annual grid electricity purchases. This model has been applied in electricity price comparisons, and in research on distributed energy
Summary
Around one in four households in Australia have installed rooftop photovoltaic (PV) capacity and market penetration is growing at the rate of about 1,500 MW per year. This article describes a novel model developed for the purpose of estimating an individual household’s rooftop PV capacity, using data on the household’s estimated annual rooftop PV exports to the grid and its volume of annual grid electricity purchases. This model has been applied in electricity price comparisons (where knowledge of rooftop PV capacity was used to estimate annual rooftop PV exports), and in research on distributed energy (where knowledge on household rooftop PV exports and grid electricity consumption was used to estimated PV capacity and gross rooftop PV production and the amount of rooftop PV used on the premises).
