An analysis of the techno-economic performance of photovoltaic-battery (PVB) systems under the Greek net-billing framework.
A new study focused on the optimisation of photovoltaic-battery systems has just been released within REN+HOMES’ framework.
The paper “Optimizing photovoltaic-battery systems for net-billing in Greece: Impact of building usage and pricing schemes”, is the result of a collaborative effort, that involved REN+HOMES’ partner Centre for Research & Technology Hellas (CERTH).
As the title suggests, the paper investigates the techno-economic performance of photovoltaic–battery (PVB) systems under the Greek net-billing framework.
Three building types (residential, retail, and office) were analysed to evaluate how building usage and electricity tariff structure influence system sizing, self-consumption, and profitability.
The result is that building usage is the dominant factor shaping PVB behaviour. In particular, residential buildings achieve the highest self-consumption (40–60%). Offices exhibit the lowest performance (5–30%) due to limited operation.
In addion, sensitivity analysis on price levels and volatility show that PV sizing depends mainly on feed-in remuneration (i.e. fixed rates per unit of energy). On the contrary, storage investment depends on import prices and price volatility. As volatility decreases, battery capacity and profitability decline, while PV sizing remains stable.
