5.4.2 The meaning of the values in the overviews
The following table contains the values and their meaning in alphabetical order.
Name
Unit
Meaning
CO
2
to
The amount of carbon dioxide emissions
that have been avoided based on the power
output.
Y-current
kWh
The current yield for the selected period
Yield Current/
Target
%
The current value displays the ratio of the cur-
rent yield to the target yield for the selected
period.
Y-max
kWh
The maximum yield for the selected period.
Y-min
kWh
The minimum yield for the selected period.
Y-avg
kWh
The average output for the selected period.
Energy
kWh
The total output for the day
Y-target
kWh
The Solar-Log™ runs a forecasting statistics
function that specifies a certain target value
for each month. If the target value or higher
has been achieved, the forecasted output has
been produced.
Y-spec
Wh/Wp
The energy yield divided by the maximum
power. This value is a good reference value
when comparing plants.
Pac
Watt
Current amount of feed-in power P on the AC
side.
Pdc
Watt
Current amount of feed-in power P on the DC
side (Solargenerator) If only one multi-string
inverter has been selected, the individual
strings are displayed separately.
P-max
Watt
Maximum output for the day.
EF
%
The current efficiency from the generator
power and feed-in power. The manufacturer's
specification on the inverter's efficiency can
be checked here.
