How it works
Built for the asset it watches
The measurement stack wasn’t just a dashboard — it was a scientifically grounded system built for our asset class.
What we measure
Zephyra instruments sit at the inverter, not at the export meter. Every string is read at 15-minute resolution alongside plane-of-array irradiance, module temperature and soiling, so what the site produced can always be separated from what the site could have produced.
Each reading is timestamped, signed and committed to the ledger the moment it is taken. Nothing is averaged, back-filled or estimated after the fact.
How it works
Field units are calibrated to the asset class they watch — crystalline, thin-film or bifacial — and re-verified against a reference cell on a fixed schedule. Readings travel over an encrypted link to the ledger, where they are reconciled against the site’s performance model and any variance is flagged within the same interval.
Operators, offtakers and lenders read from the same record, so a performance question is settled by looking, not by negotiating.
What you get
A bankable, instrument-level record of output that survives audit, refinancing and ownership change. Performance ratios that update every interval. And a curtailment and availability history that can be traced back to a single string on a single afternoon.
Capabilities
What comes with it
01
String-level metering
Every string read at the inverter at 15-minute resolution, with module temperature and soiling alongside.
02
Irradiance reconciliation
Metered output checked against plane-of-array irradiance so under-performance is caught in the same interval.
03
Sealed readings
Each interval is signed and committed to the ledger the moment it is taken. Nothing is averaged after the fact.
04
Lender-ready reporting
Performance ratio, availability and curtailment histories in the format financing partners already accept.
