What is performance testing for photovoltaic products?

Efficiency Demonstration – prove your product will meet its target efficiency at 10, 20, 30 years or more. Intertek offers Performance Testing for Photovoltaic Products helping you differentiate yourself with component testing, module Testing and system audits.

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 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.

Why is NREL collecting data from the pvdaq photovoltaic performance database?

NREL is collecting data from PV systems around the country with the goal of capturing the bigger picture of how degradation and failure rates may vary with location through the PVDAQ photovoltaic performance database .

How to reduce the cost of photovoltaic systems?

One key factor of reducing the costs of photovoltaic systems is to increase the reliability and the service life time of the PV modules. Today’s statistics show degradation rates of the rated power for crystalline silicon PV modules of 0.8%/year [Jordan11].

How does TÜV Rheinland test a photovoltaic module?

TÜV Rheinland employs a test procedure according to IEC 62716 [IEC62716] “Ammonia corrosion testing of photovoltaic (PV) modules”, which is based on the Kesternich test. Table 7.4.1 shows the test parameters of the Ammonia corrosion test procedure.
