thats just the PV generation data. there's plenty of other data that is collected.
BTW to give you an idea of just how much PV generation bounces around, here's 15 minutes of aggregate data. note how "TotPow" column varies from 1903Wh @ 12:54:58pm then its at 4820Wh @ 12:56:58pm then back at 1426Wh @ 12:58:58pm.

have similar data from the meter data as measured by energy distributor. in this case its 03 and 13 data from the meter for net consumption and net generation.
happy to supply perl code that grabs this from UE easy energy portal.
Code:
mysql> select from_unixtime(t),consumption_wh,generation_wh from ueeasyenergy order by t desc limit 48;

finally, also have some clamp meters on some circuits here - e.g. reverse cycle A/C as well as PV solar net (because meter data from energy distributor/retailer cannot tell you what power you're consuming internally), but thats pretty specific to our setup here.
none of this is hard to generate and if you have a TOU meter then its typically available via a web portal anyway regardless of which energy retailer you're with.
