Im not sure I understand your question, the code you have copied is from the config.php. This is the ID that is shown if you link to just the index.php of the climate file without any parameter. You can create links to other locations in the menu by simply specifying it like this:
…/climate/index.php?q=XXXX - this will show whatever location you want. And the climate ID in config.php is what is loaded when linking to just …/climate/index.php
- you must create your custom log I guess, which will contain all the parameters including the S, I am not 100% sure how to do it, but I remember someone here said it is possible. Other option is importing your current logs to Excel, pasting the solar data, save as CSV and do the CSV import.
