Attila,
I tried to simulate with the Photovoltaic Thermal component "type 50". It calls for the subrutine solcell and asks for a file which contains data about the cells used. This file should be in 9F10.0 format. I tried to look it up in fortran books with no luck. Could anyone tell me how this file format should look like?
9F10.0 simply means that you should provide 9 real (floating point) numbers with 0 digits after the decimal point. You should not interprete this litterally however, since SOLCEL requires some numbers that are likely to be smaller than 1 (hence should have some digits after the decimal point). The (very) important thing to know is that each number is expected to span over 10 characters exactly. The numbers will NOT be read correctly if they do not have decimal points and are not aligned properly.
Please also note that the code seems to expect 4 lines with respectively 2, 6, 6 and 6 numbers (each of them using exactly 10 characters):
XICELL CELLPF TL TH CL CH VOCLL ISCLL ISCHL ISCLH ISCHH ACELL EG AOMIN DAODC RSH RSMIN CONTR DRSDC NSER So an example data file would look like (KEEP THE ALIGNMENT): 0 0.8 43 175 6 20 0.625 0.649 0.625 2.16 2.16 0.0004 14000 1 0.018 10000 0.01 10 -0.005 10Finally, please note that SOLCEL was part of a user-contributed group of components in TRNSYS 15. I attached Appendix 3 of the TRNSYS 15 manual, which gives a description of the input file, but you will notice that there is a difference in the order of the parameters (ISCLH and ISCHL are reversed compared to what is here above, based on the code). The format is also wrong (2 lines of 9 numbers vs. 3 lines of 6 numbers) but that has no impact on the results (the Fortran "read" statement will handle data correctly). Unfortunately I do not have more information on SOLCEL so you should use it with care.
