Hello! I am sending my
question again with the hope that someone will reply. Thanks
!
Dear All,
I am currently trying to
compare the difference between a simple PV panel ( type103)
and a PVT collector (type560) but I am not getting the
expected results, because the output of the PVT is less than
that of the PV which doesn’t make sense. My calculations are
the following : I calculated the type103 efficiency by
multiplying the module’s current (Parameter 7) with the
voltage(Parameter 6) at the MPP for reference conditions and
divided it by the product of the insolation at reference
conditions (P 5) and the module’s area (P 12). That
efficiency I entered to the Parameter 18 of type560. I also
made the areas of the two components equal ( 71,2 m2 in my
case ) and changed the tubes number to 712 so it would have
the same ratio as the default setting which is 10 tubes/m2.
By doing so I expexted to have a higher electrical yield
from the PVT but that was not the case. Did I do something
wrong with my calculations ?
I am attaching the
project’s files.
Thanks a lot,
Jim Soukoulis.
