Greetings Dr Waqas

I hope you find the help you receive through this ning group helpful to you in your use of RETScreen.

I expect that after using it for 2 years and given your background in energy technology, you are in a position to both provide help to the ning group members as well as receive help.

Please do not hesitate to share concerns, requests for comments or ideas for improvements to RETScreen with this group.  We are really hoping that the "crowd sourcing" aspects of method development will play an increased role in RETScreen's development.

All the best

Richard Hellen

ning group manager
