WWTP solar analytics

The solar installation at the Waste Water Treatment Plant went on-line recently, and residents can now track how much electricity it is generating for them.  This was the email today about access to the on-line analytics, which are really pretty cool.  The school kids would love to see how much electricity is being generated, and the global warming savings it causes –

Good morning everyone,


Below is the link to view real-time production of the solar array.  The initial screen will show the lifetime kWh production and instantaneous kW output.  The “Site Analytics” tab will allow you to view historic data.  (Note: there is only one week of historical data available as that data logger was only recently installed.  However this doesn’t affect the lifetime kWh number.)




FYI we pay approx $0.13/kWh, so as of today we have saved $5,600 in utility costs since the system came online.


Best Regards,
