Profitability of Building Integrated PVs Enhanced by Storage and Load Management

In this paper, the economic viability of PV-battery systems integrated in pubic buildings is assessed, considering the various financial parameters met in countries of the Mediterranean region, such as systems cost and electricity tariffs. Specifically, a detailed techno-economic model that takes into consideration the flexibility of building loads is used to evaluate the profitability of PV-battery systems in the Mediterranean region. A sensitivity analysis is also conducted to study the effect of load flexibility level and financial parameters on the highest energy self-sufficiency that can be reached by the buildings in this region. The investigation in based on real electrical consumption measurements from public buildings and up-to-date electricity tariffs from three countries, i.e., Cyprus, Greece, and Italy.
