Home battery systems
Time for a home battery?
Now that the benefit of the reversing meter has been abolished by the ruling of the Constitutional Court of Flanders, many homeowners with PV and a digital meter are exploring the possibilities of purchasing a home battery.
Home battery advantage
The great advantage of a home battery is that it allows your customer to optimize their self-consumption. By storing the self-generated energy in the battery for later use, the customer can better manage his energy needs and purchases. As a result, the injected energy is not reimbursed at too low a price.
How a home battery works
If the solar panels generate more than is used, you store this energy in a battery. Charging the battery is possible as long as the battery is not fully charged. As soon as the solar panels generate less than is used, the battery jumps in to supply the desired power. The battery supplies energy as long as it is not discharged to the point that the battery may be discharged. This parameter is indicated by DoD (Depth of Discharge).
Did you know:
The Flemish government grants a premium on home batteries for consumers. The premium is €250 per kWh of actual capacity of the battery system. Actual capacity is determined by the percentage of the battery's DoD (Depth of Discharge).
A home battery has a capacity of 5 kWh and a DoD of 90%. The subsidy for the consumer is then 5 x 0.9 x 250 = €1,125
The premium is limited to max. 35% of the investment costs or € 3,200
