Solar panel production figures

OK I went back to my home assistant tonight and figured out the yaml file relationships, debugging the syntax then restarted. It worked. I now have it updating the pvoutput once in the evening instead of polling every 5 mins like some seem to do.

I do once an hour with a condition on it's daylight or an hour after it, I do find the hourly breakdown values useful.

The main benefit I can see to doing 5 or 10 mins is the current generation chart is much more useful if that matters to you.

For example Ron-ski on 5 mins really shows the generation patterns:

Ronski's SE System 4.000kW

PVOutput.org - share, compare and monitor live solar photovoltaic output data
pvoutput.org

On mine it's not that useful, but total generation is valid:

HipposLair 4.810kW

PVOutput.org - share, compare and monitor live solar photovoltaic output data
pvoutput.org

I would certainly encourage posting through the day on a schedule even if it's only hourly like my current one is, it means you'll appear through the day on the Live table :)
 
Sorry it was not meant as I don't think you should do it, more so that if all your doing is populating the total generation, date figures - its pointless updating periodically when you can trigger a timer at the end of the evening to do it the once. I am from the back end side of design/dev and reducing pointless traffic is common for work tasks. If that makes sense.

Oh I deal with some of the same sorts of things as you do, and yes I agree pointlessly spamming data makes no sense.

But the value here is that you'll show up for comparisons sake in the day time along with the rest of us, it makes you more visible in the table of doom sunshine.

Along the same line of thought as this, the data here seems fairly minimal (it's a timestamp, a few small values, and tracked against your instance id) - I'd say that hourly is very reasonable will be tiny data in the scheme of things.

The site could enforce keeping N records per day or a retention period as well should they want to cut down on data logging somehow.

Your call ultimately though!
 
I will prob switch to hourly then as I see it or change my ct clamps going forward (I need one to capture live import), but currently do not have a battery so the statistics are not as plentiful as most of your setups. I do have the eddi but its the older version without built in wifi otherwise I could have hacked that app and stolen more data. :)

Key one is really generation at any given point of the day, assuming it captures and shows that, it's the main metric I look at. The current generation is handy as well but ultimately total kWh generated is 99% of what I look at :)
 
Beautiful cloudless sky this morning, looking at the cloud forecast it should remain pretty clear all day… should be a good day for setting a benchmark of what’s possible at this time of year!

Didn’t charge the packs overnight, still got 44% and the Solar is starting to take over… I feel a lot of exporting in my future.

when my new efergy hub arrives i will hopefully be able to send data straight to pvoutput and appear on the live tables as the hub already has the settings to send to pvoutput.....i'm going for hourly updates
 
Really need to sort out some insulation for the packs next winter at least - was a very cold night and they are currently limited to 25A charge rate which means I’m already exporting a lot… hopefully they warm up soon!

I had to put some charge in my cells this morning, as the smart meters were being changed between 8 and 12 and didn't want to risk then arriving early and the batteries being flat,they arrived at 9:15 and it only took 10 minutes so would have been fine, especially with the amount of solar coming in.

It's a bit cloudy, but hopefully it will start generally sunny.

Sorry to say they takes ages to warm up.
Wickes have some good insulation, fire retardant, https://www.wickes.co.uk/Kay-Metzel...lation-Board---1200mm-x-600mm-x-50mm/p/253855

I havent finished mine yet so they are probably 80% insulated but keeps the pack temps far more stable.

The batteries don't generate much heat in reality. Its only the conversion losses in effect and you talking a great big heavy chunk of mainly metals. They really take some heating!
 
Looks like my shading has pretty much gone, generating full power on both strings already, may still get some later in the day, but should be charging the batteries up to 100% based on todays outlook, which will be the first time since last October!

Probably need to insulate the wall behind the packs too as it’s on a single skin exterior wall… definitely on the to do list.

It has stepped up to 30A now from 25A, so slowly but surely warming up a little.

I think its more charge level than temps if they work like mine
Well some combo of both actually

When they were really cold they would ramp up slowly without any change in battery temp
When they are warm they will ramp up really quickly so that 5 min charts look like they start at max charge rate (5.5kw)
