FOSDEM 2024: feedback

[peterdudfield]

Would be great if anyone has any feedback from our FOSDEM 2024 talk and demo. This can be feature requests, bug reports, or just a discussion.

Talk - https://fosdem.org/2024/schedule/event/fosdem-2024-2960-quartz-solar-os-building-an-open-source-ai-solar-forecast-for-everyone/

I think you mean FOSDEM (not FORSDEM)

I did not catch the start but found the presentation interesting

I do some pottery/ceramics and whilst I don't have an electric Kiln and PV panels, I have friends and fellows who do and see the software and forecast as a very useful tool.

I hate reinventing the wheel so before I try and develop something, are you aware of anybody who has written a WordPress PlugIn for generating and displaying a forecast?

The link in Installation section of https://github.com/openclimatefix/Open-Source-Quartz-Solar-Forecast is missing a the "t" in Forecast https://github.com/openclimatefix/Open-Source-Quartz-Solar-Forecas

[KeithSloan]

I have a WeatherFlow Tempest weather station and I also have it feed Weather Underground https://www.wunderground.com/dashboard/pws/IWINCH75/graph/2024-01-24/2024-01-24/daily

I thought I might be interesting to see how well a forecast matched what the weather station saw. The tool displays Kilowatt Capacity? I assume from the example based on the parameter capacity_kwp=1.25.

Now my understand is that not all PV are equal and they have different efficiencies in term of converting solar radiation energy to electricity energy, so couple of questions.

• What efficiency does the model assume?
• Can I modify an option to assume 100% efficiency so that I can directly compare what the model predicted to the Solar Radiation that my weather station is allegedly measuring?

The README has

Which does not produce the plot shown. What is needed to produce the plot is in the the examples Juypter Notebook

HI @KeithSloan

Thanks so much for your feedback. We really appreciate it.

1. Wordpress plugin This library is fairly new, so I would be very surprised if someone has. It would be great to hear how you get on with this. I have to admit I don't know much about Wordpress plugins.

2. missing t Thanks for pointing this out, we'll make sure to fix this

3. PV efficiency Great question, and it's a slightly complicated answer. We don't assume any efficiency of the panels. This is because we trained the model using variable weather variables directly to KW values. The efficiency of the panels can be effected by temperature humidity e.t.c. I would probably adjust the capacity value until it matches up, please do let us know what you found, I find this really interesting.

Also note once #36 is done, you could add your live values in, and the forecast would be more accurate.

4. Readme.md example plot Thanks for pointing this out. We'll adjust this. I think if you use 2023-10-31 you get the plot in the readme.md

Thanks again @KeithSloan, please do let us know anything else

@zakwatts @rachel-labri-tipton is it worth adding a link to the talk you did to the readme? We could always host the video ourselves on youtube, if we are worried about the link breaking

[zakwatts]

Yes I think that's a good idea.

[rachel-labri-tipton]

that sounds like a good idea, @peterdudfield

[peterdudfield]

Whats the link? And I cant put it into the readme

[zakwatts]

Heres a link to the video on youtube: https://www.youtube.com/watch?v=NAZ2VeiN1N8 Heres a link to the original FOSDEM video: https://fosdem.org/2024/schedule/event/fosdem-2024-2960-quartz-solar-os-building-an-open-source-ai-solar-forecast-for-everyone/

[roshnaeem]

@zakwatts, I see the video link hasn't been added to readme yet. If this is something pending, should I add the video link with a bit of an introduction to FOSDEM? Maybe, also OCF YouTube channel link?

[zakwatts]

Hi @roshnaeem. Yes you are correct this hasn't been completed yet. I have created a PR to do this so please feel free to add it! #96
