Why do we need a performance guarantee for a large photovoltaic system?

Documentation of the energy yield of a large photovoltaic (PV) system over a substantial period can be useful to measure a performance guarantee, as an assessment of the health of the system, for verification of a performance model to then be applied to a new system, or for a variety of other purposes.

How do you document a photovoltaic system?

Example Table Documenting the Meteorological Input Parameters to the The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s.

How to validate PV plant performance at provisional acceptance phase?

To validate the PV plant performance at Provisional Acceptance phase, the PR test is conducted over a limited period and compared to the guaranteed PR, set based on simulations. The usual duration of PR tests is 7 to 15 days, depending on the contract.

How do you test a photovoltaic system?

The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s. A longer test must be used to verify the system performance under a range of conditions.

Are there gaps in PV performance data?

Gaps in PV performance data: Some PV assessments relied on incomplete or low-resolution measured production data, which affects calculation of availability metrics. In some cases, the data was missing for ranges of dates.

Should irradiance data be removed from PV performance data?

In any case, data for the same time period must be removed from both the irradiance and PV performance data. In the case of curtailment, it is assumed that the model originally quantified the output assuming curtailment. The expected energy should be calculated in the same way.
