An initial estimate of home energy self-sufficiency can be obtained using the independence calculator from HTW Berlin: HTW Independence Calculator
For more accurate estimates, we use PV Sol to simulate yields and energy independence at one-minute intervals.
After the first year of operation, the operating data is then analysed.

After the first year of operation, the operating data is then analysed.
The following examples show some of these analyses:
10kWp system with 12kWh battery storage
The house is heated by an air-to-water heat pump. 60% of the energy generated is exported to the grid.52% of the household's energy demand is met by the PV system.
Reference yields 2
12kWp system with 12kWh battery storage and an optimised heat pump operating with a buffer tank.
50% of the energy generated can meet 65% of the energy demand.
Reference yields 3
Examples of two typical systems with an annual electricity demand of 4,000kWh.
A 6kWp system with 6kWh battery storage was installed.Washing machine use, which increases electricity demand, is scheduled for midday.
The customers are mindful of their energy consumption.
