Dear Laurent, I already encountered this kind of issue. It is due to the uncorrect handling of latitude in type 16g in TRNSYS17 (there was no problem in TRNSYS16). You should put the opposite of your place latitude in the parameters of type 16g. Yes, it is a really strange error!

I only make the following simulations : the first all over the year (0 to 8760) and the second only on a period (one week in June). And I look at the horizontal total radiation and the total radiation on a vertical slope facing south. The results I obtain are surprising : everything goes right with the first simulation, i mean that the period of time during which a radiation is calculated is ok (approximately 9-10 hours during winter and spring to 15 hours during summer). But in the second simulation (in June), i only have 10 hours of radiation. More, the total radiation on a vertical slope facing south is very high. It seems like type 16 is always thinking the simulation is running during January. I have changed the starting simulation day time in Type 16. Can someone help me ? Thanks in adavance.
