I updated my cronjob that logs data from my Solar Inverter using Curt Blank's aurora (which I've packaged for Ubuntu), to additionally submit my data to PVOutput.org. You can see my array's current day live data at: http://pvoutput.org/intraday.jsp?sid=3085, and from there, click through various views of daily, weekly, monthly, etc. reports.
I backfilled the last 1.5 years with monthly output totals, but as of July 31, 2011, I should have much more granular outputs, corresponding my my cronjob which runs every 15 minutes.
Having done that, I see that our array is currently ranked 3rd in overall power generation of all arrays registered at PVOutput.org! That won't last too long, though, as there are a couple of much bigger arrays gathering sun a lot faster than ours, so I grab a screenshot for now :-)
A current snapshot from my inverter shows these values:
Current date/time: 01-Aug-2011 12:30:01 Daily Energy = 11.692 KWh Weekly Energy = 47.445 KWh Monthly Energy = 11.691 KWh Yearly Energy = 6253.736 KWh Total Energy = 18596.278 KWh Partial Energy = 10700.143 KWh Current date/time: 01-Aug-2011 12:30:05 Input 1 Voltage = 279.369812 V Input 1 Current = 12.553665 A Input 1 Power = 3507.114990 W Input 2 Voltage = 272.658813 V Input 2 Current = 3.934551 A Input 2 Power = 1072.789917 W Grid Voltage Reading = 235.901169 V Grid Current Reading = 18.746544 A Grid Power Reading = 4391.979980 W Frequency Reading = 60.016804 Hz. DC/AC Coversion Efficiency = 95.9 % Inverter Temperature = 67.880447 C Booster Temperature = 61.183586 C
The key number there is: Total Energy = 18596.278 KWh. That means that we've generated 18.6 megawatt-hours of power to date!
I also added the PVOutput widget to the bottom of the right column of this blog.

Hi Dustin,
ReplyDeleteI just managed to compile the aurora code on my ARM-NAS and I'd like to know how you integrated its output with pvoutput.
I'm also trying to get data from my EnviR CurrentCost power meter into the NAS and then uploaded to pvoutput.org, I can keep you posted with updates if you are intersted on that.
Bye
Francesco
Hi Dustin,
ReplyDeletePerfect! You have done what I was exactly trying to do with one minor difference: I'd like to run all my scripts from my QNAP NAS (ARM based).
I already managed to compile Curt's software on it and I'd really like to know how you integrated it with pvoutput.org.
My plan is to feed my pvoutput account also with the total current consumption readings coming from a CurrentCost meter.
Thanks
Francesco
