Re: [Talk-GB] Tools to support solar panel mapping?

[Gregory Williams]

I was thinking the same thing on the "hot-spots" functionality the other day. 
I've just added that now. There's now a layer chooser, allowing choice between 
"Comparison" (as before) and "FiT", which colours between the least and most 
installations according to the FiT register in that local authority.

I'll try to address the other points as I get time -- all good points.

Updated version should appear online over the next few minutes.

Gregory

Hi Gregory,

I suspect this does not currently take account of roof-top solar power mapped

(3,760 mapped as nodes, 625 as ways), compared with your total of 621. I added 
solar panels on 3 houses on Saturday (one with 2 .generators because they face 
in different directions). It would be massively helpful if nodes could be added.

In general it is much, much easier to map roof top solar as nodes, perhaps with 
an estimate of the number of modules in the panel(currently we use 
generator:solar:modules for this). Once one has one's eye in for a particular 
area and sets of imagery it's best to capture the data as quickly as possible. 
Mapping panels as areas is more complex, for relatively small gain. I did this 
for a single area initially, and now tend to do it in two cases: a) larger 
panels on schools, commercial buildings etc; and b) newly observed panels 
noticed as part of general surveying or just casually. The choice of which to 
do will depend on panel density in a neighbourhood, and whether buildings are 
already mapped.

It'd be useful to have something like

Re: [Talk-GB] Tools to support solar panel mapping?

I note that the FiT register data does have the LLSOA for each entry. So I 
think that could be used as a means of measuring completeness in a more 
granular manner than local authority or the first half of the postcode. The OSM 
data can also be determined per LLSOA. Both the number of installations and the 
total generating capacity could be used. It'd never be perfect, but would help 
to identify areas to survey on the ground.

Re: [Talk-GB] Tools to support solar panel mapping?

[SK53]

For solar panels as nodes I have been adding two things which could fulfil
these criteria:

   - A count of solar panel modules (the roughly 1.5 by 1 m individual
   panels) with generator:solar:modules.
   - Orientation (as generator:orientation) which can be in degrees or one
   of the 16 points of the compass.

The former is probably the most useful, as it is a good proxy for optimum
power capacity (roughly 320-370 W per module) and thus could be used
immediately in things like OpenInfraMap. Orientation is just one factor in
determining likely actual capacity which would be quite complex. It is
useful when an installation spreads over more than one part of the roof.

Fails "solvable by any normal human by answering a simple question",
it requires drawing a geometry.

One option for this is turning generator=solar nodes into areas.

There was one attempt[1] but it was poorly fitting StreetComplete design.

To fit StreetComplete it must be 

- refining existing objects, not adding new ones
- be solvable by any normal human by answering a simple question

Re: [Talk-GB] Tools to support solar panel mapping?

A few thoughts:

   1. The technologies used by OpenSolarMap by Christian Quest and others
   Etalab.could be applied to OS OpenLocal buildings with a suitable training
   set. The original French data used high quality imagery classified by cloud
   sourcing as to roof orientation (flat, E-W or N-S) and then applied this to
   the rest of France.
   2. The available data on installations is via the FIT scheme itself, but
   is only broken down by postcode district which is really too large for
   basic searching. A breakdown by postcode sector would be much more helpful
   & not likely to infringe any privacy aspects. I put a list of the top 25
   districts on the wiki.
   3. Additional information which could be used to identify candidates
   are: road orientation (E-W being best); housing age (available for most but
   not all MSOAs IIRC) with Victorian & pre WWI semis & detached houses being
   poor candidates, 30s & 70s council house terraces good ones; social housing
   (I have shape files for England based on NROSH data) as many HAs and
   at-length council housing arms have been very active in installing solar.
   4. I canvassed social housing experts on twitter for likely sites, again
   skimpily listed on the wiki.
   5. The new DG Vivid layers, at least near me, are much more recent and
   better for seeing rooftop solar installations.
   6. Scanning an area you know for rooftop solar installations is not too
   arduous, and could be done more systematically for smaller areas over the
   course of the quarter. I think Colm suggested mapping rooftop installations
   as nodes & I support this (at least in first instance). The huge benefit is
   that it often highlights other things which may be out-of-date or obviously
   in need of a survey, so it can fit well with 'local patch' mapping.
   7. I hope to soon blog about my analysis of Nottingham solar in terms of
   these external parameters (FIT installations, housing age, road
   orientation, social housing etc.).
   8. For ground solar, moisture index on Sentinel imagery can be useful to
   suggest candidates. We now also have access to a cloud free composite of
   2018 Sentinel in OSM editors.

Jerry

Obviously we are talking about home/small-scale solar here. It could get
quite involved, I'm sure that people are running whole businesses trying to
analyse satellite imagery for this. Need to keep it simple and practical
for this project, unless people have lots of time and energy to spare.

An analysis (or link to an analysis) of the official stats could be useful.
Exactly how did they make their estimates?

Another idea: councils are making an effort to put panels on their
properties. Could we FOI request them? or maybe someone has already done so.

[Talk-GB] Tools to support solar panel mapping?

[Dan S]

Hi

Related to the idea of solar panel mapping, I've had a request for
info about what sort of software tools might help support this work.
We might be using some of the familiar tools (e.g. streetcomplete,
openinframap, ... even tasking manager?).

It'd be useful to have something like
completeness-by-postcode-district. Unlike Robert's postbox tools, we
don't have any official ID numbers for the items-to-map, we just have
some official stats (to be taken with a pinch of salt) about how many
are in each postcode district - but still, that could be a start.

I'd also be interested in some tool that predicts where to look, which
might be based on analysing imagery, but perhaps more realistically
based on some mix of heuristics and official data.

Any thoughts?

Best
Dan
