Alternatives for current net metering policy for solar PV in the Netherlands: a comparison of impacts on business case and purchasing behaviour of private homeowners and on governmental costs
article
To stimulate grid-connected solar PV systems on private dwellings, the Netherlands currently have a netmetering policy, but questions have been raised on its continuation. In this study, several alternativepolicy options were assessed on thefinancial case for private homeowners investing in a PV system(simple payback time), on purchasing behaviour (using a technology adoption model), and on govern- mental costs. While continuation of net metering policy leads to ongoing improvement of thefinancialcase up to levels that could be considered overstimulation, three policy alternatives can be set up so thatthey stabilise simple payback times of recent and future generations of PV systems. Under these alter-native instruments, deployment of PV systems in this market segment is indicatively estimated to be 15e20% lower by the year 2030 than with continuation of net metering policy, while correspondinggovernmental cost reduction indications would be more than 50%. We conclude that from a costeffectiveness point of view there is reason to change to an alternative instrument. We did notfind anydecisive arguments pro or con either of the three alternative instruments, neither on the basis of thethree main impacts analysed nor from other aspects reviewed more qualitatively.
