Cost-Effectiveness Analysis of Smart Photovoltaic Energy Storage Containers

Does electrical battery storage improve PV self-consumption?

A study carried out by Wang et al. on the technical and economic assessment of PV-battery systems revealed that although the application of the electrical battery storage led to enhancing the PV self-consumption, the payback of the PV system alone is short compared to the scenarios in which the battery system is integrated as well.

Why should you invest in a PV-Bess integrated energy system?

With the promotion of renewable energy utilization and the trend of a low-carbon society, the real-life application of photovoltaic (PV) combined with battery energy storage systems (BESS) has thrived recently. Cost–benefit has always been regarded as one of the vital factors for motivating PV-BESS integrated energy systems investment.

What is the cost-efficient size of a battery energy storage system?

Hence, the cost-efficient size of the battery energy storage system increases as the battery market prices drop equal to 2 kWh for the scenario in which the battery system’s market price is equal to 200 €/kWh and reaches over 8 kWh when the market prices ideally drop to around 100 €/kWh.

Is a PV battery system economically favorable?

Moreover, the techno-economic analysis of the PV-battery system performed by Li et al. concluded that the application of the battery system coupled with the PV system is only economically favorable under policy conditions in which the feed-in tariff is low, and therefore prioritizing self-consumption of PV-generated electricity is favored.
