光伏项目决策：质量、性能和经济价值

2026 What is IEA PVPS TCP? TheInternational Energy Agency (IEA), founded in 1974, is an autonomous body within the framework of the Organization for EconomicCooperation and Development (OECD). The Technology Collaboration Programme (TCP) was created with a belief that the future ofenergysecurity and sustainability starts with global collaboration. The programmes are made up of 6,000 experts across government,academia,and industry dedicated to advancing common research and the application of specific energy technologies. The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of theTCPs within the IEA and was established in 1993.The missionof the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstonein the transition to sustainable energy systems.”Toachieve this, the Programme’s participants have undertaken a variety of joint researchprojects in PV power systems applications. The overall programme is headed by an Executive Committee, comprised of one delegate fromeach country or organisation member, which designates distinct ‘Tasks,’ that may be research projects or activity areas. The 28 IEA PVPS participating countries are Australia, Austria, Belgium, Canada, China, Denmark, Finland, France, Germany, India, Israel,Italy, Japan, Korea, Lithuania, Malaysia, Morocco, the Netherlands, Norway, Portugal, South Africa, Spain, Sweden, Switzerland, Thailand,Turkiye, the United Kingdom and the United States of America. The European Commission, Solar Power Europe and the Solar EnergyResearch Institute of Singapore are also members. Visit us at:www.iea-pvps.org What is IEA PVPS Task 13? Withinthe framework of IEA PVPS, Task 13 aims to provide support to market actors working to improve the operation, the reliabilityand thequality of PV components and systems. Operational data from PV systems in different climate zones compiled within the project will helpprovide the basis for estimates of the current situation regarding PV reliability and performance. The general setting of Task 13 provides a common platform to summarize and report on technical aspects affecting the quality,performance,reliability,and lifetime of PV systems in a wide variety of environments and applications. By working together across national boundaries, wecan all take advantage of research and experience from each member country and combine and integrate this knowledge into valuablesummaries of best practices and methods for ensuring PV systems perform at their optimum and continue to provide competitive return oninvestment. Task 13 has so far managed to create the right framework for the calculations of various parameters that can give an indication of the qualityof PV components and systems. The framework is now there and can be used by the industry who has expressed appreciation towards theresults included in the high-quality reports. TheIEA PVPS countries participating in Task 13 are Australia, Austria, Belgium, Canada, Chile, China, Denmark, Finland, France,Germany,Israel, Italy, Japan,Morocco,the Netherlands, Norway, Spain, Sweden, Switzerland, Thailand, and theUnitedStates of America.
