This Application displays statistical data about my photovoltaic system, mostly in graphical form.

It should demonstrate as well, that one could easily use my implemented interfaces of php-RGraph to RGraph's javascript framework for own web-applications, in order to present numerical data in an attractive form.
This Application has been developed to show how my interfaces to RGraph Charting can be used in a Web-Application, (e.g. as a Wrapper Application within Joomla!). It uses enhanced web technics with javascript, e.g. Ajax to load html-contents and charts dynamically. There is no need to reload the displayed pages entirely, they are just updated upon request with the new content.


Data on daily output (for daily power yield and power profile) are not completely recorded for the years 2016 to 2020 and are therefore partly incomplete.

Documentation about my RGraph interface and the complete source (php files and javascripts) of this application will be made available ASAP. Please understand, that I may answer question e. g. via email, but cannot give (yet) more support than that for it
