Industry vision on standardisation

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

Status of the European standardisation• PV Industry is mature and PV components

are now on the market, so Standards MUST ensure fair competition

• European procedures need to be improved and made faster.

• No sufficient feed back to the Industry on what the standard institutions are developing (testing procedures)

• Unclear added value for the end-users

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

Industry questions

1. Re-viewing from standardisation institutions of their procedures and practices taking into account industry needs

2. And so, answer relevant questions raised by the industry:– Does standardisation is an added value for the PV

industry in the field of the international competition?– Where are the limits of standardisation in PV?– What are the ways for improvement of procedures– How to solve identified bottlenecks?

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

How to answer these questions• Prioritize on the Industry needs

• Integrate the Industry inside the standardisation process

• Consider the market situation and its growth

• Establish confidence between standardisation institutions and industry

• Consider the international dimension

Recommendations

• Improve communication issues between the stakeholders (institutes, industry, governments representatives, etc.)

• Establish clear and comprehensive procedures (e.g. CENELEC)

• Develop only useful standards for the industry

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

Industry recommendations

• Make procedures more transparent• Diminish the time needed for the

development of standards• Harmonisation of testing procedures• Unify standards and certificates at

the international level

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

Conclusions of the first dialogue between Industry and Standards Institutes• The main conclusion is for mandatory

standards to improve the procedures and for non-mandatory targets to produce specifications by and for the industry

• Based on the experience of the semiconductor Industry, EPIA asks the support of SEMI (Semiconductor Industry organisation) and the collaboration of DKE (German National Technical Committee)

20th European PV Solar Energy Conference and Exhibition, 6-10 June 2005, Barcelona

SEMI Experience on non-mandatory standards (specifications)

• Industry expansion strained supply chain and led to silicon shortage

• The great variety of tools, processes, and materials in use led to over 2,000 different user-created specs for Si wafers – and still no standards!

• A SEMI® sponsored silicon wafer standardization effort was undertaken to eliminate the waste of having non-standard wafer sizes that nobody else could use

In the Seventies

SEMI Experience on specification

Growth and Expansion

• Success of the silicon standardization effort provided the momentum of the SEMI®

standards program for the next several decades

• New areas for standardization were added : Chemicals, Equipment, Packaging, Photomasks, etc.

Conclusion

• Industry Commitment and Support (industry participation of both suppliers and users)

• Timing (Excellent when compared with mandatory Standardization procedure, SEMI Specifications can be developed and published in 9 months!)

• Development of the ‘right’ specifications and measurement procedures

• Usage of the specifications (Well acceptance by the suppliers and the users)
