Hi All
I've now got a pretty dashboard
http://emoncms.org/dashboard/view&id=28500
What I'm quite interested in is how much of the energy I generate is actually used by me and not include the units I export to the grid.
Having installed the panels, basically I want to work out how much I've earned and how much I've actually saved by scheduling stuff to work during the day.
I don't have a solar cache system (no hot water tank) so I do export back. I don't want to include the export amounts in what I'm reporting.
ie during the day I've generated 2kw and used 10kw. 1kw went back to the grid as export, 1kw was actually used by me.
Therefore I've only used 9kw.
Therefore my "earnings" are 12p for energy generated, 2.5p for export tarrif and I've saved an additional 12p for the energy used. That'll give me a better idea of how much the panels have actually saved me.
Re: Units "Saved"
I use the standard mysolar app that used to be in emoncms and is now unbundled to sit alongside.
I put a small diff in this forum earlier to add a metric for how much solar I export as opposed to use.
I'm also interested in tracking the monetary side of it but I've got to add Economy 7 and my EV car into the mix. I have defined a bunch of feeds using schedules that separate out the kWh numbers but I have not yet got to building a customer dashboard. Any ideas on visualization would be welcome!
