Profitability of photovoltaic battery systems considering temporal resolution

The rollout of residential photovoltaic (PV) battery systems is mainly motivated by cost saving. Investment decisions are often based on general figures such as the yearly electricity consumption. Simulations used for scientific publications often use standard load profiles or measured load profiles of a specific household. In the latter case, the decision of adequate temporal resolution has to be made. Our study analyzes the impact of temporal resolution on the expected profitability that is calculated based on simulations. In order to quantify this effect and its uncertainty, we conduct a study based on measured load profiles of 30 households.
