Bankability, from portfolio to sensor
Every plant gets one score out of 100. Open it to see which station costs points, then which of the six parts of the score, then the reading behind it.
01Portfolio
Every plant on a map with its score. Only the plant that needs you is marked.
02Plant
Each station at the plant, ranked by how many points it costs the plant.
03Station
Each sensor on the station and the checks it passed or failed.
04Six parts
The score split into its six parts, largest loss first, with what to do about it.
The six parts of the score
Validity · 25%
The readings that arrived passed the quality checks.
Availability · 20%
The data your sensors were meant to send actually arrived.
Traceability · 20%
Each instrument has an in-date calibration certificate from an accredited laboratory.
Consistency · 15%
Sensors measuring the same thing agree, inside tolerance.
Stability · 12%
Readings have not drifted from where the rest of the evidence says they should be.
Maintenance · 8%
Cleaning happened on schedule and faults were closed on time.

Raw and Corrected, side by side
Raw is the record as your sensors delivered it. Corrected is the record Wedant delivered, with missing intervals filled and every filled interval tagged. Both are scored with the same formula, so the gap between them is what correction recovered.
Scored around the clock
The night counts. A pyranometer that reads sunlight at midnight is a critical fault under the method, not an hour to skip.
Every station, checked
Physical checks run on every sensor. Passing checks stay silent; only a failure asks for your attention.
Physical range
Readings stay inside what the instrument can produce.
Flat line
The signal moves, not stuck at one value.
Sampling cadence
Samples arrive on schedule with no large gaps.
Data availability
Enough of the window reported.
Saturation
No long spells pinned at a sensor limit.
Responsiveness
The sensor follows changes in the weather.
Noise floor
Sample-to-sample noise stays in its envelope.
Statistical outlier
No sample far from the recent median.
Timestamps
Records in order, none duplicated.
Calibration offset
Bias against the plant consensus stays in tolerance.
Drift
No slow walk away from the consensus.
Correlation
The shape of the day tracks the neighbours.
Cluster agreement
No conflict with sensors mounted beside it.
Site-wide agreement
Agrees with the plant as a whole.
Soiling watch
No steady daytime shortfall that points to dirt.
Logger health
The logger keeps reporting normally.
Spike detectionComing
Sudden jumps between samples.
From a failed check to a ticket
Check
A sensor fails a physical check, such as a flat line during daylight.
Cause
Wedant names the likely cause: a frozen sensor, soiling, drift or a calibration offset.
Ticket
The fault becomes a maintenance ticket against the station, for the site manager to assign.
Raised on its ownComing
Wedant raising tickets itself once a day, with one email per person.
What Wedant finds
Pick a sample station. Each one carries a fault Wedant looks for, and shows what it means and what happens next.
- Check failed
- Flat line
- What it means
- The reading froze from 11:20 to 13:05 while the neighbours kept moving. A stuck sensor, or a logger repeating its last value.
- What happens next
- A ticket to inspect the sensor and logger. The frozen span is flagged in the record.
- Part of the score it costs
- Validity
The whole plant, side by side
Every station's irradiance and temperatures in one table, each set against the plant consensus. The table stays quiet until one of them drifts away from the rest.
| Station | GHI W/m² | GTI W/m² | Module °C | Air °C |
|---|---|---|---|---|
| WMS 01 | 812+0.4% | 948+0.4% | 51.2+0.4% | 33.4±0.0% |
| WMS 02 | 806−0.4% | 941−0.3% | 50.8−0.4% | 33.1−0.9% |
| WMS 03 | 819+1.2% | 953+1.0% | 51.9+1.8% | 33.6+0.6% |
| WMS 04 | 741−8.4% | 866−8.3% | 50.5−1.0% | 33.2−0.6% |
| WMS 05 | 809±0.0% | 944±0.0% | 51±0.0% | 33.5+0.3% |
| Plant median | 809 | 944 | 51 | 33.4 |
WMS 04 reads about 8% low on both pyranometers. Likely soiling: the shortfall holds all day and the temperatures agree.
Deviation from the plant
How far each station sits from the plant consensus, per parameter.
Satellite imagery
Cloud imagery over the plant beside an incident, to tell a real cloud from a faulty sensor.
Limits that adaptComing
Tolerances set by sensor class, plant layout and elevation, in place of a fixed 5%.
Satellite cross-checksComing
Every irradiance sensor compared with satellite estimates as advanced analytics.
A standard for weather data
We want bankability scoring to become the standard for weather data worldwide, starting with Europe and the US. A standard has to be the same everywhere and open to inspection, so the score is built that way.
One published weighting
The weights are the same for every site and no customer can change them, so scores compare across plants and owners.
Open to inspection
Every coefficient behind the score is written down, so an engineer can check a number against the method.
Versioned
Each score carries the version of the method and the weights that produced it, so an old score stays readable.
Questions
Do I need Aeron hardware to use Wedant?
No. Wedant reads the stations you already run on Live3, from Aeron or any other maker, and historical files from other loggers can be loaded for you. Every station is checked and scored the same way.
Is the night scored?
Yes. The score covers the whole day. At night a pyranometer should read zero, so one that reports sunlight at midnight is a sensor fault, not a quiet hour.
Can the score be compared between plants?
Yes, and that is the point of it. The weights are published and the same for every site. No customer can move one, so a score at one plant means the same as a score at another.
What does early access include?
Everything on this page not marked Coming. We onboard early-access customers one at a time, with your own stations and data, and the parts marked Coming arrive as they ship.
