IED has developed a simple method of quality control integrated all along the design and implementation process of the 3000 SHS project in Mauritania. PV applications are rather new in the country and stakeholders were at the beginning not much concerned by quality issues. Working together with a local partner (subcontracted under this project), IED has adapted the QA approach to the local conditions, validated the test procedures and implemented the quality control procedures.
This programme was launched in early 2003 with special attention on quality issues, starting with appropriated specifications in the call for tenders, followed by preliminary testing on proposed components, both at international and national level, quality of local private operators, quality control and testing at delivery stage and specific procedure for field commissioning and testing of installed systems. Special support to the end-users and the private sector from the component suppliers to the local service providers is definitely crucial for the sustainability.
Local discussions have been initiated about implementation of national quality standards, testing centre and training accreditation not existing yet. IED has evaluated the operating status and performances of the SHS installed in Mauritania and compared quality control approach with other partners� experiences to establish general guideline.
The Peruvian Ministry of Energy and Mines (MEM) is implementing a PV program in the Amazon region, which is part of a GEF funded project; the objective is to install 1000 Solar Home Systems using a financial scheme based on an Energy Service Company.
The IES is advising in the tender documents: all the aspects related with the technical prescriptions and the methodology to test the fulfilment of the technical conditions. A practical seminar for test laboratories was organised in April of 2003 in Lima. About 25 technicians coming from six different Peruvian organizations dealing with the subject were participating. At the end of last year, the tender process was finished.
The next step was to advise about the capacity of three local laboratories, which are competing to undertake the certification process. In March of the present year we have visited the three laboratories to evaluate their facilities and technical skill. Two laboratories were selected; after the electrical tests of the same SHS, which will be made by the two Peruvian laboratories and the PV Systems Laboratory at IES, the MEM will choose the certification laboratory. However, due to internal problems the program was suspended by the MEM and a new tender process has been activated in the last year.
This is the final report of the first work package of the TaQSOlRE project called: Analysis and evaluation of solar rural electrification markets. In this first report of the TaQSolRE project, an analysis of the current status of solar rural electrification in developing countries is presented, focussing on quality aspects. It is based almost exclusively on an extensive literature review. At the end of 2003, an estimated 3.4 million households benefit from solar rural electrification, of which 2.4 million through solar home systems.
Combining survey results from different sources, it was found that 63% of the installed solar home systems are still working well, and 15% is not working at all. An overview is presented of field findings regarding the different technical- and non-technical problems causing these early failures of solar systems. Quality assurance activities have been implemented to a certain extent in a number of countries. But their impact on actual quality levels still remain under discussion. The document contains useful information for everyone professionally involved in quality aspects of solar rural electrification. It is especially useful in the planning stages of rural electrification projects. Designers of balance of system hardware will find data and background information on technical failures.
The proposal document �Quality control for stand-alone inverters: Technical Standard and certification tests� is intended to provide a quality reference for procurement specification issued by National Governments, donors and investors.
In addition, it is intended to be useful as a design guideline for manufacturers and installers. It should be understood as a follow-up of the �Universal Technical Standard for Solar Home Systems�, which applies exclusively to entirely DC SHS. Besides, this standard for inverters is restricted to only deal with the AC part, i.e., inverter and AC load.
The document contains a discussion of inverter performance at the lights of the following criteria: reliability, safety, energy performance, user friendliness, and installation and maintenance.
The document was circulated among external experts in the subject, but we are receiving few comments. There are not many people with enough skill, who is disposed to review it in depth.
The document entitled �Guidelines for Commissioning PV Stand-Alone Systems�, deals with specifications for commissioning PV systems, as a complement of a previous PV component quality control stage. Together with the list of requirements, explanations about their need are supplied. It has been written focusing on its usefulness for institutions but also, and mainly, for technicians. This document has to be seen as a part of complete
Quality Assurance procedures implementation, which should cover pre-installation, installation and post-installation stages. Its impact on PV stand-alone systems performance would be detected only in the long-term. To contribute on the extension of this kind of practices within installers and promoters would be a positive result. These guidelines constitute deliverable nº 5 of the project.
The PV reliability database is hosted on the TaQSolRE website (http://www.taqsolre.net). The objective is to gather first hand reliable data from various countries (eight at present) in which the project partners have presence and create the database from which inferences regarding quality assurance, reliability and user satisfaction can be drawn. At present the tool to analyse the data is also made available on the web site through standard and user defined simple queries. It is available to any user after filling up a simple on-line registration form (one time).
As the number of visitors (users) to the web site increases, it is expected that contributions in the base data may also be available from some reliable and serious users. The TaQSolRE partners may decide to incorporate such data on the web site after assessing its authenticity. As the data sample size increases, statistically significant information regarding mean time between failures, most frequent failures, quality assurance procedure applied versus the mean time between failures, etc. can be extracted.
This theoretical research (deliverable 8) item is centred on the technical approach for improving stand-alone PV system quality through dependability analysis, based on field and laboratory experience. Dependability issues cover reliability, maintainability and availability concerns. The effects of component failures and the lack of energy (loss of load probability) of PV systems with real components are analysed, which is an advance step on traditional reliability studies. The end-users of this result are mainly researchers and PV program designers (systems and maintenance). First results were presented at Paris 19th PVSEC held on June 2004. A more advanced research has resulted in a scientific article accepted for publication in the international journal Progress in Photovoltaics, in april 2006.
The TaQSolRE website (http://www.taqsolre.net) objective is to create a PV reliability network to disseminate results and to contribute to a better knowledge and understanding of the quality aspects of PV stand alone systems. Quality Assurance Procedures and Best Practices to deal with the energetic reliability of PV Stand-alone systems are presented on the web-site.
The site includes a web based data base created based on the first hand survey done by the TaQSolRE partners. A tool to analyse the available data is also made available on the web site through standard and user defined simple queries. As the number of visitors to the web site increases, it is expected that contributions in the base data may be available from some reliable and serious users. It may be incorporated on the web site after the TaQSolRE partners form a consensus on it. The web site also serves as an outlet for all the public domain documents generated under the present project.
The site was launched in the tenth month of the project and is continuously being improved based on the user inputs. At present, it contains information about stand-alone solar systems from eight countries around the world. All deliverables and articles developed within the project are available, together with other external related documents.
