Can energy storage systems be used in residential buildings in Nordic climates?

Methodology To evaluate the financial feasibility of implementing energy storage systems in residential buildings in Nordic climates, the use of energy storage technologies in combination with a solar PV system was modelled for detached houses employing different heating methods in Southern Finland.

Can solar PV systems be used in Nordic climates?

Thus, to simulate the use of solar PV systems in Nordic climates, the model included scenarios with both a fixed solar PV capacity of 5 kW, representative of a typical residential solar panel in Finland , as well as with a fixed RF of 49 % for the house, with the solar PV capacity determined accordingly.

How big a solar PV system does a detached house need?

The modelled results now instead show how a larger solar PV system up to 13.5 kW would be needed to meet the renewable energy demand of detached houses without energy storage, whereas a 5.1–10.8 kW solar PV would be sufficient with an energy storage system.

Can energy storage systems be integrated with solar PV in detached houses?

In order to evaluate the financial feasibility of integrating energy storage systems with solar PV system in detached houses, economic indicators able to compare the costs of the different storage scenarios with one another are needed.

What is the optimal capacity of solar energy storage systems?

Hence, the optimal capacity of all the energy storage systems is zero, whereas the feasible solar PV size is limited to below 20 % when using the 2019 electricity prices as comparison.

Is Lib storage a good alternative to a stand-alone solar PV system?

While the costs of all energy storage systems remain too high to be considered financially attractive without further support mechanisms, LIB storage is clearly the best storage alternative in all scenarios with a LCC 1000–7500 € higher and a LCOE 0.005–0.04 €/kWh higher than the costs of a 13.5 kW stand-alone solar PV system.
