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.
Yspec 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.
