Photovoltaic self-consumption after the support period: Will it pay off in a cross-sector perspective?

23.08.2018 | HWWI Research Paper 182 | von Lars Ehrlich, Jonas Klamka, André Wolf

We quantify the cost savings potential of photovoltaic self-consumption by single-family houses with small-scale roof-top photovoltaic (PV) systems in Germany against the background of recent storage applications after the end of the legal support period. We analyze different systems where an already installed PV system is combined with battery storage and/or a...
