6 Frequently Asked Questions about “Photovoltaic cell scale classification standards”
What is the world photovoltaic scale (WPVS)?
This paper presents an overview of the World Photo-voltaic Scale (WPVS) international reference cell calibra-tion program. The WPVS provides a scale for PV performance measurements that has been established through round-robin calibration of a group of primary refer-ence cells and is traceable to Système International (SI) units.
What is a photovoltaic reference device?
This standard covers photovoltaic reference devices used to determine the electrical performance of photovoltaic cells, modules and arrays under natural and simulated sunlight. The main technical changes with regard to the previous edition are as follows:
What are the regulatory levels for photovoltaic systems?
At least three regulatory levels for the production, installation, operation and end of life of photovoltaic systems can be considered. Additionally, the Life Cycle Assessment methodology is also regulated by standards. In this chapter, the three levels are presented.
What standards are available for the energy rating of PV modules?
Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
Does photovoltaic calibration involve electrical and radiometric measurements?
Photovoltaic calibrations involve both electrical and radiometric measurements. Electrical traceability is routinely achieved through calibration of instrumentation to SI trans-fer standards, but radiometric traceability is not as easily attained.
How many IEC standards are there for photovoltaic technology?
There are currently 169 published IEC standards by TC-82 related to photovoltaic technology, and work is in progress for 69 more (new ones or revisions). This set of standards is the most broadly used by the scientific community and technicians in research centres and companies.
