U.S. China Renewable Energy Partnership
• One of seven bilateral initiatives announced by Presidents Obama and Hu in
Beijing November 2009
• Created by Memorandum of Cooperation for “Establishing a U.S. China
Renewable Energy Partnership” for bilateral cooperation in renewable energy
• Managed by U.S. Department of Energy and Chinese National Energy
Administration through National Renewable Energy Laboratory in U.S. and
Energy Research Institute in China
• Five active areas of cooperation established each with its own working group
• Policy and financing
• Wind joint research cooperation
• Solar joint research cooperation
• Grid integration
• Standards, testing, and certification
• First Annual Renewable Energy Industries Forum held in Beijing May 2010
• Second Annual Renewable Energy Industries Forum held in Washington D.C.
Sept 2011
• Working Group Meetings of Standards Testing and Certification: CGC, NREL,
CEPRI, UL, INTERTEK

Standard Area IEC Working
Group/Other
Description
New PV Module Rating System and
QA Standards
WG-2 NREL and Japan-AIST initiative for new rating system
for assessing PV module performance for development
of QA standards
PV Module Materials Standards WG-2 New standards for materials in PV modules including
encapsulants, backsheets, edge seals and adhesives;
and testing methods for TCO and antireflective coatings
on glass. China is also interested in i) light induced
degradation, ii) curing EVA; and iii) nominal operating
cell temperature for BIPV systems.
Inverter Qualification Tests WG-6 Revision of IEC 62093 standard (inverter standard and
qualification test)
Module System Bias Voltage Test
Method
Test method for system bias voltage stress effects and
module system bias degradation mechanisms and tests
as part of the Revisions to edition 3 of IEC 61215
PV System and Grid Integration
Standards
WG-3 Systems acceptance and grid interconnection standards
Accelerated Aging Standards WG-2 Accelerated aging for PV modules; specific interest of
CGC
Grid Interconnection Standards IEEE Standards for grid connection for experimental testing
and verification of all aspects of grid equipment; power
quality; relay protection; voltage/active power; security;
stability; anti-islanding

• PV Module QA Standards
– New PV module rating system for assessing module durability in variable climatic conditions
– Quality assurance standards development
– Go beyond IEC qualification test standards
– NREL in US and AIST in Japan; support generated from several China companies/organizations
– PV Quality Assurance Task Force
