To reach its climate targets and secure its energy supply, Switzerland needs to multiply the annual deployment of renewable energy technologies, especially solar PV (as also shown in the SWEET EDGE inter-model comparison). The EDGE Policy White Paper quantifies the level of fragmentation of policy targeting PV on rooftops of households in Switzerland.
First, the White Paper analyzes the relevant policy designs on federal, cantonal and municipal levels, detecting a strong variety on both the cantonal and municipal level, as well as between distribution grid providers.
Second, it models the effect of this fragmentation on the profitability of PV installations on exemplary building types, finding extreme variance, even within cantons.
Finally, it proposes a strategy to reduce this policy fragmentation while increasing ambition in favor of a targeted harmonization of selected policy instruments to create stronger incentives for accelerated solar PV deployment and to reduce unnecessary barriers.
