[esp-r] Re: Question about PV electricity production

Dear Maria, Ian and all
thank you for your answers, I found the code and the equation but it =20
is not yet clear what you want to say with:
"the effective irradiance reaching the PV module by taking into =20
account the reflectance of the module's front cover at the angle of =20
incidence, at 60 degrees and at 0 degrees".
That means that an interpolation is made from 0=B0 to 60=B0 to reduce the =
=20
irradiance reaching the module to evaluate the electricity production. =20
The following formule is not really clear for me:

fQPnl =3D ( EXDIR(ispmloc(ISPMNOD,2)) * fTrans_IncAng +
       &           EXDIF(ispmloc(ISPMNOD,2)) * fTrans_60 ) /
       &         fTrans_0

Can you explain me it?

Regards

Francesco
