Estimated system losses
are all losses in the system that cause the energy actually
delivered to the power grid to be less than the power
produced by the PV modules.
•
Cable loss (%) / default 1%
PVGIS24 is based on
international standards for line loss in cables. this loss
is estimated at 1%. You can reduce this loss to 0.5% if the
quality of the cables is exceptional. You can increase the
line loss of the cables to 1.5% if the distance between the
solar panels and the inverter is greater than 30
meters.
•
Inverter loss (%) / par défaut 2%
PVGIS24 is based on the
average of inverter manufacturer data to estimate the
production transformation loss. The international average
today is 2%. You can reduce this loss to 1% if the quality
of the inverter is exceptional. You can increase the loss to
3% to 4% if the chosen inverter offers a transformation rate
of 96%!
•
PV loss (%) / default 0.5%
Over the years, the modules also tend to lose some of their
power, so the average annual production over the life of the
system will be a few percent lower than the production in
the first few years. The various international studies
including those of Sarah and Jordan KURTZ estimate an
average production loss of 0.5% per year. You can reduce
this production loss to 0.2% if the quality of the solar
panels is exceptional. You can increase the loss from 0.8%
to 1% if the solar panels chosen are of average
quality!
