IEC TS 63049
Terrestrial photovoltaic (PV) systems – Guidelines for effective quality assurance in PV systems installation, operation and maintenance
|Publication Date:||1 September 2017|
|ICS Code (Solar energy engineering):||27.160|
This document provides the minimum activities deemed necessary to implement an effective Quality Assurance program for the managing and reducing of risk in the installation and operation of photovoltaic (PV) systems. This document defines requirements for certifying that an entity has and uses a Quality Assurance program to prevent, or reduce errors and learns from any new errors in:
a) installation, and
b) operation and maintenance of a PV system.
The object of this document is to provide more confidence in the performance and reliability of certified PV systems. By being installed and operated under a Quality Assurance program in accordance with this document, PV systems are expected to operate as designed and as expected based on product warranties.
This document is developed to facilitate implementation of the quality control scheme under the IECRE program, for those who choose to use the IECRE program ("IEC system for certification to standards relating to equipment for use in renewable energy applications").
NOTE This document has been written primarily to apply to large PV plants and similar schemes. Requirements for residential systems and smaller scale installers are being considered for a future version of this document. This document also assumes these requirements apply to the prime contractor who, in turn, is responsible to hold subcontractors and other service providers to the intent of these requirements.
This document is applicable to all PV systems independent of design and technology, i.e. flat panel, Concentrator Photovoltaic (CPV). Quality controls for CPV and nonconventional flat-plate systems will differ somewhat from those of more conventional designs; this document has not considered these differences and is expected to be generally applicable to all PV systems.
This document covers processes starting from the shipment of components out to the installation site and including the transport, unpacking, racking, construction, module installation process and processes associated with operation and maintenance of the PV system.
Compliance to a Quality Management System (QMS) such as ISO 9001 will meet many requirements in this document. The requirements that are unique to this document can be combined with the ISO 9001 audits for those organizations that are already registered to ISO 9001:2015. For the organizations who do not have ISO 9001 registration by a certified body, the entirety of this document applies.
Assessments with respect to this document may be completed to certify a Quality Assurance program for the installation process, for operations and maintenance processes or for both processes.
Clause 4 describes requirements for the installation process; Clause 5 describes requirements for operation and maintenance.
Maintenance of PV systems is often lumped into the catchall term "operations and maintenance" (O&M) This document does not address business or management operational processes (e.g. forecasting, utility pricing incentives, etc.) or other considerations driven by factors outside of basic system working condition, safety and performance.
