Solar tagging app

Russ Garrett
Hi folks,

I got annoyed with tagging the number of modules in solar generators,
so I put together a quick crowdsourcing app to collect this data:

https://solartagger.russss.dev/

It's definitely a lot quicker than trying to do this in an editor!

Once we have panel counts that multiple people have agreed on, I'll
batch insert the data into OSM using a new account - I will update
this list once that is happening.

Cheers,

Thanks Russ!

I was only thinking of a similar idea just the other day. I've already
gone through probably a couple of hundred installations. Perhaps a
future extensions could allow:
- A "Are you sure that's a PV system?" option -- I've seen perhaps a
couple where I'm not sure whether it's actually a PV system. Perhaps a
check from another imagery source, or a ground survey, could clear
things up?
- Click twice to measure the orientation (although perhaps more suited
to using on a computer, rather than a mobile / tablet?)

Cheers,

Gregory

Thanks! We've got about 1000 agreed module counts now, which I'm now
working on batching up and submitting as an edit.

I was originally planning to add multiple "skip" options but I decided
to keep it simple. I have the data on which generators are being
consistently skipped though, so we can potentially go through those
later to try and find nonexistent/mistagged things.

Orientation is next on my list when I get a moment (probably not
imminently). It'll likely be a separate task from the module-counting
one. Location is also another task which I could potentially add.

Nice job Russ.

Have/can you add a paragraph to the OSMWiki Renewable Energy in the United Kingdom page please (or the solar-specific page?).

We now have around 1500 nodes with agreed module counts. I've started
submitting these to OSM and an example changeset on 20 nodes is here:

https://www.openstreetmap.org/changeset/92055795

(The "imagery_used: Bing" and "bot: yes" changeset tags will also be
added to future changesets.)

I will pause for a few hours in case anyone spots any issues with
this, but it should be fairly straightforward. I have also added the
appropriate wiki page to document these automated edits:

https://wiki.openstreetmap.org/wiki/Automated_edits/solartagger

I've just spent a couple of days working on Vale Park, Evesham and many
of the units have panels on the roofs, so I think that is next on my
list to do ... problem is I've not mapped these before, so what is my
best starting point re adding them.

All the info you need is (hopefully) here:

One difference I make vs. that is "direction" rather than
"generator:orientation".  In iD, at least, you get a nice visual
of the view-angle then.

I use a point and a module-count.  If it's flat, I use "tilted:no"
rather than a direction.

https://overpass-turbo.eu/s/YLx  is my current "look for missing
tags" hunter.  Pick your area then hit the Run button.

Let's officially change over to "direction" then. I've edited the wiki
page to reflect that.

Re: Solar tagging app

Gregory Williams-2
I've now got round to updating the code on my solar comparison site to
cater for these different ways of tagging the orientation. It considers
these tags in this order:

- generator:orientation=*
- direction=*
- tilted=no

Regular users of the site may have noticed that I also recently added
counts of mapped orientations and module counts to the chart on the
summary page. A noticeable jump in the counts for orientation should be
seen in tomorrow morning's update.

Cheers,

Gregory

Suggestion for further improvement:  When a building is identifiable
associated with a set of generators, only count one for comparison
against the FIT data.  Then (say) a house with panels on two different
roof-faces will not over-count for the geographical region.

(I just found an LSOA with 4 of 13 mapped.  But 2 were on one home.
A terrace too, so now I must split it, so the 1 on another home in
the block is really distinct)

Jeremy,

That certainly is one reason why the "completeness" figure is just a
guide, rather than an absolute. Perhaps you've seen that there are, for
example, some regions that have greater than 100% "completeness", and
I'm sure that multiple installations on a property does contribute to
this. Comparison with the FiT register will always never be perfect,
since as external observers we don't really know whether the multiple
sets of modules on a property are part of the same or separate FiT
contracts.

If the multiple instances on property have the same roof orientation
then you could use a multipolygon to collate those instances together.
Obviously this wouldn't be suitable for the multiple-roof scenario that
you describe, though.

You've also, pointed towards one of the gotchas that only counting a
single installation per property would currently have in many places.
We've got plenty of places where a terrace of houses have only been
mapped as a single building. Thus several installations, each on
separate properties, would only appear to be one installation when on a
single terrace building. It does, of course, give an incentive to go
out and map the addresses individually, of course! :-)

I'll consider how implementing this may be done in the code, but I
think it'll need some general tidying of it first; so wouldn't
necessarily be available straight away.

BTW, the code does actually do something similar already wrt solar
farms, to avoid overcounting the individual lines of modules in a
plant.

Cheers,

Gregory
