PRODUCT CERTFICATION

Q.SMART has a very strong roadmap planned with even higher efficiencies


All aperture areas efficiencies

Q.SMART has a very strong roadmap planned with rapid cost reductions

� Cost reduction of more than 60% over last year due to:

� Scale-effects (ramp-up)

� Efficiency increase of > 1 percentage point

� Yield increase by 22 percentage points since January

2010

PRODUCTION COST PRODUCTION COST REDUCTION TO < 0.5 $/Wp


� Expansion of supplier base

� Process optimization

� Increased uptime

� Still significant cost-optimization potential for both fabs

after ramp-up

� Expansion of additional 500 MW with next-generation

production technologies would allow cost reduction to

< 0.5 $/Wp

The ugly side of product robustness of modules in field conditions in India, and also elsewhere


*

1.Solar Energy Centre at SolarCon 2010

2.SunPower at NREL International PV Module QA Forum Meeting 2011

There are three main factors for the underperformance of modules on the field

• The experience of manufacturers currently supplying modules is limited

1. Many industry participants are new to PV

2. Internal QA processes not at required standard


• The manufacturer’s attitude to quality varies and customer service

2. Internal QA processes not at required standard

• Newly understood phenomenon like Potential induced degradation (PID) are not accounted for, in manufacturing process

3. Lack of R&D for long-term performance

But wait, isn't product & performance guaranteed by manufacturers? Unfortunately “it depends”.

“The Limited Warranty does not apply to any PV Modules which have been

subjected to (…) electrical surges, lightning, flood, fire, vandalism, tampering,

accidental breakage, mold discoloration, or other events beyond <Supplier’s>

control, including without limitation any technological or physical event or

condition that is not reasonably known or understood at the time the Customer

purchased the PV Modules”


-- An extract from a warranty clause from a Tier-1 Chinese cSi module manufacturer

Fact: It could be worse with modules with Tier-2,3 manufacturers

Q-Cells has established one of Europe’s largest PV testing conditions in a manufacturing premise

The Module Test Line has the following facilities

� 16 climate chambers for reliability test (capacity for 240 crystalline modules or 720 thin-film modules)

� 4 light soaking + 3 UV-systems

� 2 flashers (VDE recognized) � additional tests ( outdoor exposure, mech. stress, hail impact, dyn. load, etc) � All tests and test equipment is approved and accredited from VDE, especially IEC61215,


� All tests and test equipment is approved and accredited from VDE, especially IEC61215, 61646, 61730 and UL1703

� All results and measurement data are recognized by VDE (TDAP)

Q-Cells modules have been one of the few to receive the VDE Quality Tested (VQT) certificate

• Identification� Easy to verify ID-Number: unique product

identifier and can be verified on-line � Separate VDE-Certificate for every product

containing the most important information.

� Benefit to customers� As a result of the certificate, Banks and

Insurance companies find it is easier to get


Insurance companies find it is easier to get financing for Q-Cells products

High reliability

Optimized durability

Low degradation

Continuous line monitoring

stringent product checks that are well beyond IEC tests

VQT is not just a product test, but also a test for the entire manufacturing process

Third Party Audit of Manufacturing Process

� Periodical fab audits by VDE

� Continuous in-line quality tests that are controlled and audited by the VDE

� Quarterly test for the correctness of the power data on the module via re-measurement

� Quarterly repetition of the test cycles on 20 modules from running production

� Quarterly climatic tests on 4 modules from running production


� Quarterly climatic tests on 4 modules from running production

In addition, Q-Cells continues to perform world wide tests on module performance in real life

WORLD-WIDE TEST SITES

� Testing of modules and complete PV systems under real conditions

� Comparing simulation and testing results from laboratory with measured data

� Developing improved simulation processes for accelerated material testing

� Show-case for customers of system components and live monitoring
