CB认证护航光伏系统投资

Shine Magazine/光能杂志 & www.solarbe.com/索比太阳能光伏网记者 Clara Chen (陈瑜）编译

人们对环保能源的需求和政府对光伏业的补贴政策，使光伏市场迅速成长。为了验证补贴的可行性，政府要求光伏组件具有安全高效的特质，这使提高组件性能的动力达到空前的高度。

光伏组件认证

测试实验室的迅猛发展，更是说明了质量，安全和组件性能验定的重要性。经过认证的光伏组件在市场中有公认的使用寿命长的特质，而且它们鲜有对组件性能不利的瑕疵。组件的测试过程历来也非常的迅速和彻底。而CB认证作为成员国公认的第一个国际认证体系，为各国的国家认证提供了极为便利和标准的认证途径。因此通过CB的努力，检测认证的优势也在与日突显。通过CB认证的高质量组件不但在市场上拥有良好的声誉，CB也为其带来了更大的市场占有率。

保护光伏系统等于有了品质的保证

除了光伏组件认证能够为您提供检测光伏系统的服务外，还有质量认证，资格预审认证，以及工具设施和大型系统认证。资格预审认证能够帮助制造商在第一时间内检测到潜在的设计缺陷。产品的设计缺陷是企业进步的绊脚石，它不但容易导致企业失信于客户，还对制造商的声誉有着莫大的影响。对进口商和经销商来说，供应链的质量检验保证了责任监控的完整。而且，为了保证装船货物和被检验样品的质量相同，装船前的监控和装卸安全检查也是必不可少的步骤。

光伏系统标准和安全测试

光伏系统有三个标准：

IEC 61730的第1步和第2步是所有组件的安全标准。

IEC 61215是针对多晶硅组件的性能和类型的资格认证。

IEC 61646是薄膜组件的性能和类型的资格认证

光伏组件的安全鉴定包括诱电性电阻以及对电流冲击和渗漏物的防护。另外，组件表面抗压测试，接地，潮湿和冰冻条件的独立检测等，都是严格测试安全鉴定的标准。

性能测试专注于效率和耐久性。例如紫外线阻力，抗人为破损能力，冰雹等不利的自然条件，都在测试范围内。

光伏系统需遵循RoHS和REACH条款的约束，这非常重要。如果在恶劣的气候条件下使用组件，例如阿摩尼亚电阻，雪载重或是沙漠环境，我们建议客户寻找额外的性能认证和担保。此外，如果是在沿海地区安装的光伏组件，那具有抗盐雾腐蚀能力的组件将是最好的选择。

一站式质量保证

SGS拥有包括制造商，进口商，和经销商在内的整个光伏产业链。而且SGS拥有多个通过ISO17025的质量体系认证的光伏测试实验室，以满足不同地域和市场的需求，提供全方位的光伏测试和认证服务。

SGS太阳能测试中心位于德国德累斯顿，是一家具有代表性的提供光伏测试服务的专业机构。以IEC 62109和SGC-CEBEC为主的逆变器测试系统可以为大型光伏系统提供测试认证服务。SGS还提供“并/离网认证”，确保电压在中压网络连接中的波动限制在范围内。此外，SGS的SSC（系统和服务认证）部门也为那些接入或附加了光伏系统，抑或有类似重大修改的电力系统提供验证。

PV Systems Investments Protected by CB Certification

The growth of the photovoltaics market has been driven by the demand for greener power sources and by increased government subsidy. To justify the subsidies given, governments require certified testing of photovoltaic modules for safety and quality. The incentive to improve performance could not be greater.

Photovoltaic Module Certification
The growth of testing laboratories testifies to the importance of quality, safety and proven performance in the manufacture of photovoltaic modules. Certified PV modules reach the market with both a proven life span and the guarantee of a lack of defects that could potentially have a detrimental effect on performance. The testing of PV modules is also now as quick and thorough as it has ever been.
CB certification is recognized by all CB Scheme member countries and often offers a shortcut to other national approval marks. Thus the benefits of certification are increased through CB certification and in addition, the CB certified PV module can enjoy the good reputation and greater market access that the CB Scheme offers to CB qualified products.

Protecting PV Systems Means Assuring Quality
Other services apart from PV module certification assure the high quality of PV systems (BOS) - these include quality testing, pre-qualification testing and the certification of facilities and large systems. It stands to reason that pre-qualification testing can help identify potential design flaws for manufacturers in the vital, early stages. Design flaws impede progress, increase customer frustration and often affect manufacturer reputation. For importers and distributors, quality testing along the supply chain is integral to the control of and monitoring of liability. In addition, pre-shipment controls and load and unload inspections are essential in the country of manufacture in order to ensure the compliance of the products for shipping with the quality of certified samples.

PV Systems Standards and Safety Tests
PV systems are subject to three standards: IEC 61730 part 1 and 2 are the safety standards for all module technologies; IEC 61215 is specific to polycrystalline silicon module performance and type qualification; and IEC 61646 covers Thin Film modules’ performance and type qualification. Safety tests verify critical features of PV modules, including dielectric resistance as well as resistance to current surges and leakages. Other safety critical components that undergo rigorous testing include access to elements under tension, grounding, and the measurement of insulation for both humid and freezing conditions.
Performance testing focuses on efficiency and durability, so for example, power efficiency, UV resistance, resistance to breakage caused by persons, objects or adverse weather conditions such as hail and so on are all measured. Compliance with directives such as RoHS and REACH is considered very important and PV systems can also certify for conformity with these pieces of legislation.
If PV modules are to be utilized under severe weather conditions, customers are advised to seek additional performance certifications and guarantees, including for example, ammonia resistance, heavy snow load or desert resistance. In addition, if the PV module is to be installed in a coastal region, tests against salt mist corrosion resistance are also highly recommended.

One Stop Quality Assurance
SGS can support the manufacturers, importers and distributors of PV modules throughout the entire life cycle of PV modules and systems. SGS offers various PV testing laboratories in key locations and markets, with all being ISO 17025 accredited and all offering the full range of PV testing and certification services. The SGS Solar Test House in Dresden, Germany is a particularly fine example of SGS’ expertise in PV module testing services. Power inverters are covered by IEC 62109-1 and SGS-CEBEC offers safety testing for these as well as large PV systems. SGS can also offer ‘connection/disconnection from grid’ certification, ensuring that voltage fluctuations remain within required limits when connection is made to networks of medium voltage. Through its SSC (Systems and Services Certification) division, SGS also verifies electrical installations that have adopted or added photovoltaic systems or have undergone other such major adaptations.
