[TRNSYS-users] TRNSYS-users Digest, Vol 171, Issue 17

Hello Everyone,

I am working a project on hybrid solar PV and Diesel Engine performance.
for this  i need my location weather data which is not present in TRNSYS
weather file. How can i use another weather data file or how can i use type
99 for my location weather generation?

Regards
