From 4617efa085ac5eb4b2df5e19b4cfcf4bcc835584 Mon Sep 17 00:00:00 2001 From: Claude Opus 5 Date: Fri, 31 Jul 2026 10:34:03 +0200 Subject: [PATCH 1/6] feat(weather): add STRANG as an irradiance source and declare source coverage STRANG becomes a real irradiance source rather than an unreferenced client, every external data source now says where in the world it works, and the location picker moves off Leaflet. STRANG's parameter set was mapped against the live API because SMHI's apidocs pages 404: exactly 116-122 exist. Identification was confirmed by physics rather than by guessing - at solar noon 121 + 122 = 723.0 + 87.5 = 810.5, exactly parameter 117, and 119 caps at 60, i.e. minutes within the hour. STRANG publishes no cloud cover; it is a radiation model. Cloudiness is instead derived from sunshine duration as 1 - minutes/60, which is observed rather than inferred but coarser: blind to thin cirrus, undefined at night. CloudCover() therefore returns an explicit unknown instead of defaulting to clear, because those two lead to opposite decisions. The new coverage registry makes an existing silence explicit. STRANG is Nordic-only and every price provider is European, so sites elsewhere were getting empty results with no explanation (#726). GET /api/data-sources now reports area, countries, licence and whether each source reaches this site, and the Weather tab renders it under the map. Bounds are advisory: STRANG's grid is rotated, so a lat/lon box can only ever be a superset - all four in-box corners were probed and returned no data. False is definitive, true means worth trying. Scoring now declines to start outside the domain instead of retrying nightly forever. Stacked on #718, which carries the plane-of-array wiring this builds on.

STRÅNG is a mesoscale +analysis product covering the **Nordic region** hourly at ~2.5 km from 1999 to +roughly one day ago. It is free, keyless and CC BY 4.0. + +Outside that domain STRÅNG returns no data, so scoring simply never produces +rows and the dashboard overlay stays hidden. Nothing fails loudly; the feature +is just unavailable. + +Because the same scoring feeds the **forecast calibration factor**, sites +outside the STRÅNG domain also do not get measured calibration of their PV +forecast — they fall back to the uncalibrated physics estimate. + +STRÅNG has **no forward horizon**. It is never used as a forecast provider; see +[architecture.md](architecture.md) for where it sits. + +### What STRÅNG actually publishes + +Probing the live API on 2026-07-31 (SMHI's own apidocs pages currently 404) +returned data for exactly seven parameters and 404 for everything else.

It is however *derivable*: parameter 119 counts the minutes +in each hour during which direct beam irradiance exceeded the WMO sunshine +threshold, so `1 − minutes/60` is the fraction of the hour the sun spent +obscured. That is an observed quantity rather than an inferred cloud field, but +it is coarser than a forecast provider's cloud percentage — it cannot see thin +cirrus that dims without blocking. FTW exposes it via +`strang.IrradianceHour.CloudCover(lat, lon)`, which returns an explicit +"unknown" rather than defaulting to "clear". + +The location argument is not decoration. Sunshine duration is zero at night for +the trivial reason that there is no sun, and zero again near sunrise and sunset +because the beam crosses ten or more air masses and cannot reach the 120 W/m² +threshold even under a spotless sky. Both would read as "100% overcast" if taken +at face value. `CloudCover` therefore declines to answer unless the sun clears +**5° of elevation** at some point in the hour, sampling the hour's start, +midpoint and end so the hour in which the sun crosses that line is still counted. + +Live data from 2026-06-21 at Stockholm shows the distinction: + +| Hour (UTC) | GHI W/m² | Sunshine | Cloud cover | +|---|---|---|---| +| 00:00 | 0.0 | 0 min | *unknown* — sun below horizon | +| 04:00 | 163.2 | 60 min | 0% | +| 12:00 | 810.5 | 60 min | 0% | +| 20:00 | 2.5 | 0 min | *unknown* — sun minutes from setting | + +## Roof geometry — Sweden only (planned) + +The roof-derivation module proposed in +[RFC #717](https://github.com/srcfl/ftw/discussions/717) reads **Lantmäteriet** +building footprints and LiDAR, which exist for **Sweden only** and require a +Geotorget account.
