Since the State Council issued the "Opinions on Promoting the Healthy Development of Photovoltaic Industry"(the "Opinions") (National Publication [2013] No. 24) in 2013, China's  photovoltaic technology develops significantly, market size expand rapidly, which provide strong market support to the photovoltaic industry. At the same time, there have also some problems, such as the backward production capacity can't exited timely, advanced technology products can't enter the market, the overall technology upgrade of photovoltaic industry is slow, and the photovoltaic power generation project have quality risks and so on. In order to promote the products application and industrial upgrading of the advanced photovoltaic technology, and strength the quality management of photovoltaic products and engineering, now make the following comments:

First, fully play the guiding role of the market for technological progress. Give full play to the decisive role of market forces in allocating resources, and improve photovoltaic product market access standards in order to lead photovoltaic technology progress and industrial upgrading. According to photovoltaic technologies and products at different development stages, it is required to adopt differential market access standards, support advanced technology products to expand market, accelerate the elimination of outdated technology products, and standardize photovoltaic technology and quality supervision and management. Gradually establish a cycle progressive mechanism of photovoltaic product, and accelerate technology advancement and industrial upgrading of photovoltaic power generation.

Second, strictly implement market access standards of photovoltaic products. Since the date of this document release, the new purchased photovoltaic modules of photovoltaic power generation projects should meet the related products technical requirements in "Photovoltaic Manufacturing Industry Standard Conditions"(2015 Version) republished by Ministry of Industry and Information Technology. Among them, the photoelectric conversion efficiency of polycrystalline silicon cells and battery pack assembly should no less than 15.5% and 16% respectively; photoelectric conversion efficiency of HCPV module should not less than 28%; photoelectric conversion efficiency of silicon, copper indium gallium selenide(CIGS), cadmium telluride (CdTe) and other thin film batteries' components should not less than 8%, 11%, 11% and 10% respectively; From the date of the project put into operation, the decay rate of polysilicon , monocrystalline and thin-film battery components should not higher than 2.5%, 3% and 5% in the first year, and the decay rate should not higher than 0.7% per year from the second year, and the attenuation rate should not higher than 20% in the project life cycle. Since the day of HCPV module put into operation, decay rate should not higher than 2% in the first year and the decay rate should not higher than 0.5% from the second year, and the attenuation rate should not higher than 10% in the whole life cycle. The index will be adjusted according to industrial development.

Third, implement the "leader" program. National Energy Board arrange a special market size for implementation of the "leader" program every year, and it requires the project to adopt advanced technology products. By 2015, the "leader" of advanced technology products should meet the following specifications: a photoelectric conversion efficiency of polycrystalline silicon cells and battery pack assembly, respectively, reach to over 16.5% and 17%; conversion efficiency of HCPV module photoelectric reaches to more than 30%; photoelectric conversion efficiency of silicon, copper indium gallium selenide, cadmium telluride thin-film batteries and other components, respectively, reach to over 12%, 13%, 13% and 12%. "Leader" program plans to implement by building advanced photovoltaic technology demonstration base and new technology demonstration. National Energy Board makes major technical indicators of progress demonstration project, construction specifications, operational management and information monitoring requirements. Provincial energy authorities select those investment enterprises which have high technical ability and investment management capacity through competitive selection mechanism, and the enterprise chose to the advanced technology product achieving "leader" requirements index through market mechanism.

Fourth, play the role of financial capital and government procurement in supporting the progress of photovoltaic power generation technology. Including the State-sponsored public projects to solve the people's concerns about no electricity and power shortage in remote areas, and photovoltaic poverty alleviation of public welfare project, national foreign aid projects, all types of photovoltaic energy demonstration projects implemented and organized by national authorities at all levels, photovoltaic projects supported by local governments using financial resources and photovoltaic projects in government agencies at all levels of building facilities installed, they all give priority to using "leader" of advanced technology products.

Fifth, strengthen the testing and certification of photovoltaic products. Strengthen photovoltaic product testing and certification capacity-building, and gradually increase photovoltaic product certification standards, improve the formulation capability of international standards and mutual recognition capability in photovoltaic industry. Photovoltaic module production enterprises should have the necessary product test and routine test ability for the components and materials used in product testing. The key products produced by the production company must pass a third-party's testing and certification, and the results must be published by of third-party testing and certification organization. The source information of polysilicon, solar cells, glass, silver, EVA, back and other key raw materials, should be clear in the product specification of the photovoltaic company, ensuring the photovoltaic products must go through testing and certification, and compliance products.

Sixth, strengthen the quality management of engineering products. The key parts such as photovoltaic modules, inverters and so on in photovoltaic power generation project, should be certificated by certification agencies which are approved by CNCA, and the real product should be in consistent with the certified product. Each photovoltaic technology development and investment companies should establish a quality and technology management system about the key equipment of the photovoltaic power generation. The technical indicators should be clearly required in the process of bidding product, product arrival and acceptance, project final acceptance. 

Seventh, strengthen technical monitoring and supervision. National Energy Bureau, Industry and Information Ministry and State Recognition Supervision Committee and other departments regularly organize technical quality examination for the photovoltaic products in the market.  It focuses on examination of photovoltaic products quality and key technical performance, and improves the technical quality of the management policy, publishes the result of the examination to the public. For those enterprises whose products are not meeting the market access standards, the result will be announced in public. The "leader" project implemented and organized by government, are evaluated and monitored by the third-party testing and certification organization in the whole process. At the time of project completion, examination will be put to make sure whether it is achieve the index of commitments or not, evaluation results will be evaluated and published one year later after the project put into operation.

Eighth, improve photovoltaic power generation running information monitoring system. Industry technical support units should be in accordance with the relevant requirements of industry management to carry out the operation information statistical work of the construction of grid connected photovoltaic power generation project. Power grid enterprises should establish and improve network operation and information monitoring system to monitor the output power and power generation data, maintaining the continuity and integrity of operational information, with the development of photovoltaic technology's quality inspection and evaluation of information service work. Project unit should submit basic information about photovoltaic power generation facilities to the National Renewable Energy Information System, including PV module type, size, power rating, mounting, inverter type, the system maximum output power. In case of project facilities maintenance and fault failure occurrence, the project unit should be promptly informed of the situation to grid companies according to the operating procedures.

Main technical indicators Description


The Photoelectric Conversion Efficiency of Photovoltaic Modules

Photoelectric conversion efficiency definition.

PV module photoelectric conversion efficiency means:  In the standards situation (AM1.5, module temperature 25 ℃, irradiance 1000W / m²) , the power ratio maximum output power of PV modules / Solar light power on the component.


Determination of photoelectric conversion efficiency: The photoelectric conversion efficiency of photovoltaic components is tested in accordance with method of GB / T 6495 by the third party testing laboratory which are identified by the national qualification (CMA). and the standards can be revised in temperature and irradiancy according to GB / T 6495.4 when necessary.

Batch production of photovoltaic components must be certificated by certification body which is approved by the national certification and Supervision Committee, and each component of the single component product's deviation between actual power and the nominal power shall not be higher than 2%. The photoelectric conversion efficiency of the crystal silicon components of several commonly used standards is corresponding to the peak power technology index:


For non-standard crystalline silicon photovoltaic modules (such as double glazing assembly), the conversion efficiency may not be suitable to the above formula, but the efficiency of the battery piece should be in accordance with the requirement of the photoelectric conversion efficiency of the battery piece in the "Photovoltaic Manufacturing Industry Standard Conditions", and it's also should be certificated by certification bodies which are approved by the state commission.


For concentrator photovoltaic modules, the standard test conditions are: AM1.5, module temperature 25 ℃, irradiance 1000W / m², and assembly area corresponding to the lens area.


The Attenuation Rate of PV Modules

Definition of attenuation rate of PV modules

Photovoltaic component attenuation rate means the ratio between the maximum output power under the standard test conditions (AM1.5, component temperature of 25 DEG C, irradiance 1000W/mL) and the maximum output power of the initial operation.

The determination of the attenuation rate of PV modules can adopt Accelerated Aging Test Method, Field Comparison Test Method or other effective methods. Accelerated Aging Test Method is using environmental test box to simulate outdoor actual operation of irradiance, temperature, humidity and other environmental conditions to achieve accelerated aging of components attenuation in a relatively short period of time through the double or strict control of the relevant parameters. After the Accelerated Aging Test, it followed by the Power Test under the standard testing condition, and according to the attenuation rate formula, the attenuation rate of photovoltaic components power generation performance can be determined.

Field Comparison Method: Extracting a sufficient number of components for sample according to the project installed capacity since the assembly operation, and then it can test the initial maximum output power according to the method of GB / T 6495.1 standards by the third party laboratory which are approved by national qualification accreditation. and measure the maximum output power again after running up a year produced in the same batch of other components installed in the same environment. Comparing with this two time's maximum output power, according to the attenuation rate calculation formula, determine the decay rate of the power generation performance of photovoltaic modules.
