Suite 1602-I, 16/F, Modern Communication Mansion 218 Hengfeng Road, 200070 Shanghai, China www.pro-q.com ©2009 Pro-Q Limited. All rights reserved. FOREWORD a. About This Audit Supplier auditing is part of the due diligence necessary to minimize risks due to exceptions occurring during development and/or operation of a solar system (loss of productivity, system halt etc.) and therefore also maximize its return. Due to the specific nature of a solar module, the buyer’s due diligence must focus on the following issues: 1.Reliability: the module will not incur in premature failures; 2.Durability: the decay in time of the module’s output is consistent to the one declared by the manufacturer; 3.Warranties: since modules come with warranties over their reliability and durability, the issuing party will exist and be capable of responding for such liabilities over the lifetime of the warranties (typically 20 or more years). In order to address such concerns, our audit focuses on the following areas: 1.Quality of the product: a.Materials; b.Production technology; c.Quality systemregardless of the quality expected from materials and production technology, the supplier must be able to intercept quality faults, cure: them, and continuously improve its own process in order to minimize further occurrences of any such fault. d.Packaging and loading: the supplier must be able to guarantee optimal packaging solutions in order to minimize occurrence of damages to finished goods during transportation; 2.Quality of the supplier organization: a.Financials; b.Market-side competitiveness: the supplier is able to attract customers and keep utilization of its production capacity at an ideal level–In the present as well as in the future; c.Supply-side competitiveness: the supplier is able to attract suppliers of quality materials, guarantee the required volumes, and obtain competitive pricing; d.Organization; The quality of the product is intended to assess, to best effort, the reliability and durability of the module, where the quality of the supplier organization is intended to assess, to best effort, the likelihood that the supplier will be able to deliver on its warranties, as in the following diagram.

As of the nature of an audit, many areas cannot be judged on a closed formula. The inspector is called to provide his/her own professional opinion on a number of issues. A number of Poor / Average / Above Average marks are assessed on the basis of such professionalism and expertise. 2.Relativity. Assessments of Poor / Average / Above Average are relative to current industry benchmarks. As benchmarks are in continuous change, the validity of such assessments is most reliable within a reasonable period of time following the date of the inspection. Such period of time varies according to the industry developments. 3.Completeness. The inspector might not be able to complete selected areas of this audit due to higher or lower supplier cooperation during the inspection. This latter is also assessed in the audit and should be part of the overall evaluation of the supplier.
