Hi, thank you for your reply. I really appreciate the contribution. However, if you are interested please go to www.rids-nepal.org. I am the web admin for this non profit ngo which helps the poorest of poor people in Nepal. You can find more in the site above. We have many Renewable Energy related systems in many villages of Humla, a district of Nepal. And we gather a lot of data each month. We have uploaded those data in a POSTGRE DB and also built a application to cpm[are the data and show the graphs. You can access this software by clicking on the DataBank (www.lannet.com.au/mall/datalog) you will reach to a log in page. But due to the limitation of the present graphing system we were thinking of using Google;s Visualization package. If you are interested then please let me know, my email add is [email protected]. I will gladly grant you a access to the Databank and you can see what i really mean. These data and graph will help our organization to optimize the design, improve reliability, reduce cost and increase system output, which all in turn allow the building of more sustainable, context related energy generation systems.
You will be helping the poorest of poor people in the world by helping in this project. But i totally understand if you dont want to do it. I respect your decision. Thank you again.
