What is PD IEC TS 62989-Concentrator photovoltaic systems?
PD IEC TS 62989 encompasses key characteristics of primary optical elements (lenses and mirrors) and lens or mirror parquets for concentrator photovoltaics including optical performance, mechanical geometry, mechanical strength, materials, and surface morphology. PD IEC TS 62989 identifies the essential characteristics, the corresponding quantities of interest, and provides a method for measurement of each quantity.
PD IEC TS 62989 allows lens and mirror manufacturers, concentrator module manufacturers, test laboratories, and other interested parties to define lens/mirror qualities and inspect lenses and mirrors. There are no pass/fail criteria associated with the document.
Who is PD IEC TS 62989-Concentrator photovoltaic systems for?
PD IEC TS 62989 on concentrator photovoltaic systems is useful to:
- Concentrator module manufacturers
- Lens and mirror manufacturers
- Photovoltaic cell manufacturers
- Test laboratories
- Entities involved with solar energy engineering
- Solar power plants
- Solar cell and panel manufacturers
Why should you use PD IEC TS 62989-Concentrator photovoltaic systems?
Concentrator photovoltaics is a photovoltaic technology that uses sunlight to generate electricity. Unlike traditional photovoltaic systems, it focuses sunlight through lenses or curved mirrors onto small, extremely efficient multi-junction (MJ) solar cells.
PD IEC TS 62989 defines the test conditions rather than to specify the precise setup of a measurement apparatus. For example, this enables laboratories to acquire reliable and comparable measurement results irrespective of the existing large variety of experimental setups for focal spot characterization. High priority is given to comparable and reproducible measurements of the irradiance distribution in the focal plane and of the optical efficiency. This requires trade-offs that reduce the similarities to outdoor conditions.
PD IEC TS 62989 thus allows lens and mirror manufacturers, concentrator module manufacturers, test laboratories and other interested parties to define lens/mirror qualities and inspect lenses and mirrors.
As a result, compliance to PD IEC TS 62989 can help enhance performance and energy efficiency of concentrator photovoltaic systems.
