Real surface of solar panels can
degrade and reduce PV efficiency
in a long-term perspective. But
another short-term effect of
reducing PV electricity production
occurs every day, especially for
the morning and afternoon hours at
oblique ray incidence. These periods
of time are really important because
cover a half of the whole daylight,
day after day.
We know how to avoid unnecessary
optical losses for these periods
making the cover glass smarter and
energetically more acceptable.
