The largest enemy of bifaciality is
the old-fashioned “Wp thinking” of
customers instead of a modern
“kWh mentality”.

summary
40
- c-Si solar cells in future will be bifacial anyhow
- many companies are already producing bifacial cells:
PERC+, nPERT, HJT, mcPERCT
- many modules in future will be glass-glass based anyhow
- the system kWh can be extremely increased by using bifacial
modules and simple tracking in addition
>> WE HAVE TO CHANGE TO COSTS/KWH THINKING,
CREATE STANDARDS AND BRING BIFACIALITY INTO PV
MARKET

Bifacial PV will not only reduce LCOE-
it will bring you to great places!!
ENJOY!!!
