      abstract     = {The German Federal Government, in order to achieve its
                      renewable energy targets, has promoted the deployment of
                      solar PV. Small residential PV installations coupled with
                      battery energy storage systems are gaining momentum, as the
                      appeal of self-consumption has grown. We conducted an
                      economic analysis to assess the profitability and optimal
                      configuration of these technologies from the perspective of
                      heterogeneous households that are subject to the current
                      German regulatory framework. In this regard, we consider
                      heterogeneous potential for the self-consumption of
                      electricity (e.g. household size, energy efficiency), as
                      well as heterogeneous financial (i.e. metrics, parameters,
                      sources of financing) and fiscal (i.e. tax treatment, tax
                      rate) aspects. We find that the use of alternative financial
                      metrics (i.e. payback period, real internal rate of return
                      and net present value) as criteria for evaluating
                      profitability has a significant impact on the rankings of
                      system configurations. Furthermore, fiscal aspects are
                      crucial to assessing profitability and marginally relevant
                      for optimal system configuration, while financial aspects
                      are of great importance for both. Our results on optimal
                      battery coupling (as opposed to stand-alone PV) show that
                      rates of adoption range between $0\%$ and $94\%$ of the
                      analyzed load profiles, following the variation of such
                      finance-related dimensions (e.g. discount rates, inflation,
                      debt versus equity financing). We conclude that such
                      findings on the impact of such factors are highly relevant
                      in terms of designing cost-efficient and effective policies
                      that aim to foster energy transitions, both in Germany and
                      elsewhere, especially at a time of very low interest rates.},
