End User Value of On-Site Domestic Photovoltaic Generation with Different Metering Options in Sweden
Abstract
In Sweden the possibility for introducing net metering of on-site electricity production is currently being investigated by the government. In this paper we investigate if and how net metering improves the economics for small-scale photovoltaics (PV) in Swedish households, as compared to other metering alternatives. Data from both simulations and measurements are used to determine the degree of matching between production and demand at different billing periods for net metering. The results show that both the value of the produced PV electricity and the system sizes that are reasonable to install vary considerably between the different options. It is concluded that net metering would have a major impact on the value of on-site generation.
