To evaluatethe electricity costs, of the PV-battery system, the progression of the power demand and electricity production is evaluated and compared with cost and revenue of the resulting energy flow based on the electricity purchase prices and the EEG bonus for the feed in of renewable solar energy.
The first settings in which they will become profitable, as prices are further declining, will be larger households at locations with higher average levels of solar irradiance. If the batteries can be remote-controlled by an aggregator to provide overnight negative reserve, their profitability increases significantly.
In case of energy spillover, the battery is charged. In case the current power output of the photovoltaic system is not sufficient to power the household, the battery gets discharged. Subsequently, the grid is used to supply the house. If the battery is fully charged, the excess energy is fed into the grid.
The photovoltaic energy cost price is estimated at about 5 cents per kWh over the lifetime of the plant, compared to an average energy cost of between 11 and 17 cents per kWh today for a business, depending on its level of annual consumption from its supplier.
Lithium-ion (Li-Ion) batteries are increasingly being considered as bulk energy storage in grid applications. One such application is residential energy storage combined with solar photovoltaic (PV) panels to enable higher self-consumption rates, which has become financially more attractive recently due to decreasing feed-in subsidies.
When the price of electricity is low, the battery starts charging immediately. When electricity prices are high, the batteries could be discharged, making a profit by selling the electricity back to the grid .
