You probably need to choose a “FullInterior*” type of Solar Distribution in the Building object.

Subject: [EnergyPlus_Support] solar absorption on a sloped surface
Hi
Trying to simulate a tilted solar collector over a roof, appears a severe error about the absorption on the floor:
** Severe ** ComputeIntSolarAbsorpFactors: Solar distribution model is set to place solar gains on the zone floor,
** ~~~ ** but Zone ="Z CHAM" floor cannot absorb any solar gains.
** ~~~ ** Check the solar absorptance of the inside layer of the floor surface construction/material.
** ~~~ ** Solar gains will be spread evenly on all surfaces in the zone, and the simulation continues...
What could I do for making my tilted floor to absorb solar gains?
As suggested for the error report, I check the solar absortance of the inside layer of that floor.
That solar absortance is set to: 0.85
Does anybody have some suggestion?
There´s also a severe error on shadowing calculations:
** Severe ** DetermineShadowingCombinations: There are 1 surfaces which are casting surfaces and are non-convex.
** ~~~ ** ...Shadowing values may be inaccurate. Check .shd report file for more surface shading details
Regards
Alejandro
