Although crystalline PV cells dominate the market, cells can also be made from thin films—making them much more flexible and durable. One type of thin film PV cell is amorphous silicon (a-Si) which is produced by depositing thin layers of silicon on to a glass substrate. The result is a very thin and flexible cell which uses less than 1% of the silicon needed for a crystalline cell.

Learn MoreAt 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.
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.
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.
Limited the documents applicability to PV modules rated for 1500 V or less maximum system voltage. Provides details on how to qualify modules at all voltages up to 1500 V. Added restrictions that this standard does not cover PV modules that incorporate electronics. This will be the subject of a new standard that is now in development.
Important factor focused in the revised version of the standard is to define the Overvoltage category for the PV Modules in line with the IEC 60664. PV installations must comply with these requirements, and PV modules are defined as Overvoltage Category III equipment, as per IEC 60664.
At a commercial Solar PV Plant, DC voltage in a string of a PV Modules may go up to 1500 VDC in accordance with NEC. Therefore, IEC 61730-1, Part 1: Specifies and describes the fundamental construction requirements for PV modules in order to provide safe electrical and mechanical operation.
