Year Data in the diagram Consumption:
• Yearly consumption: Energy that your household has drawn from
your PV system (direct consumption), the utility grid (purchased
electricity) and, if applicable, the battery (battery discharging) in the
year selected.
• Purchased electricity: Energy that your household has drawn from
the utility grid during the year selected.
• Internal power supply: Energy that your household has drawn
directly from your PV system (direct consumption) and the battery
(battery discharging) during the year selected.
• Battery discharging*: Energy that your household has drawn from
the battery during the year selected.
• Direct consumption*: Energy that your household has drawn
directly from your PV system during the year selected, without
intermediate storage in the battery.
Data in the diagram Generation:
• Annual yield: Energy that your PV system has generated during the
year selected.
• Self-consumption: Energy that your household has drawn directly
from your PV system during the year selected (direct consumption)
and the energy that your PV system stored in the battery (battery
charging) during the year selected.
• Battery charging*: Energy that your PV system has stored in the
battery during the year selected.
• Grid feed-in: Energy that your PV system has fed into the utility grid
during the year selected.
Additional data:
• Self-sufficiency quota: Ratio of internal power supply to yearly
consumption.
• Self-consumption rate: Ratio of self-consumption to annual yield.
• Direct consumption rate*: Ratio of direct consumption to annual
yield.
