Repowering Analysis

Repowering analysis evaluates whether replacing inverters or upgrading parts of a PV system is worth it. sunalysis models inverter replacement and system upgrade scenarios against the plant's real operating data, and after a retrofit it can measure whether the upgrade delivered.

In short

Evaluation of inverter replacement and system upgrade scenarios.

How it works

  1. 01

    Data analysis

    Ingest SCADA, meter, and weather data.

  2. 02

    Modeling

    Build expected performance baselines.

  3. 03

    Loss ID

    Isolate and quantify each loss category.

  4. 04

    Reporting

    Clear, defensible technical reports.
