Open data · Open-Meteo + PVGIS + Ember

Benchmark your solar parkagainst the physics.

Voltperia turns your plant's technical sheet and coordinates into an expected performance baseline — irradiance, yield, PR and CO₂ avoided — so you can spot underperformance the moment it happens.

How it works

From a pin on the map to flagged anomalies — in three steps.

01

Configure your park

Drop a pin on the map, enter installed capacity, tilt and azimuth. Takes 90 seconds.

02

Voltperia models the physics

Hourly irradiance from Open-Meteo + PVGIS module physics produces the expected baseline.

03

Compare and act

Upload your real CSV and Voltperia flags every day where actual fell below expected.

What's inside

An expected-performance baseline, on demand.

Every feature is wired to public, audited datasets — no black-box ML, no guessing.

Configurable virtual parks

Define location, technical specs and topology — Voltperia models the rest.

Global weather in real time

Open-Meteo and PVGIS cover China, Europe, USA, LATAM and Africa.

Power curves & expected yield

Hourly AC power and specific yield, modeled from your tilt and azimuth.

CO₂ avoided tracking

Country-level emission factors from Ember Climate, refreshed yearly.

Performance Reports (RPE)

Monthly or annual PDF reports with executive summary, PR analysis and tables.

Multi-day forecasts

Pro plan unlocks 7-day forecasts with daily irradiance & temperature bands.
