Reliability Terminology and Formulae for Photovoltaic Power Systems   总被引:1,自引:0,他引:1  
Photovoltaic (PV) solar energy systems operate in a unique environment compared with most electronic and electrical power generation systems. The input stimulus, solar radiation, is both highly variable and noncontrollable. This presents a certain amount of difficulty in measuring and reporting reliability, maintainability, and availability characteristics. Many of the terms, definitions, and performance indices employed in other fields do not directly apply and need to be revised (tailored) to the PV technology. This paper proposes reliability and availability terms, definitions, performance indices, and mathematical expressions. The rationale for their relevance in photovoltaic solar energy technology and applications is given. There is a need to provide uniform terminology and formulae, for effective communication. Such communication promotes the orderly development of a uniform and effective reliability methodology for PV systems and components. The material draws extensively from ANSI/IEEE Standard-762, which defines reliability, availability, and productivity terms for electric power generation systems. This paper extends the standard terminology to include PV power systems. The unique characteristics of the PV array and the variability of input energy are described. The language will grow as PV technology and associated reliability and maintenance methodology are further developed.  相似文献

With manufacturing capacity ranking number 5 in the world in 2005, China is rapidly emerging as an important player in the global silicon solar cell and module market. Production capacity has been growing by more than 70% per year over the last 7 years and future ambitious plans for the further expansion of the domestic production are likely to transform China in one of the largest (if not the largest) PV hubs in the world. However China's ability to fulfil its goals is challenged in the short term by a global shortage of silicon and in the medium to long term by the ability of the government to stimulate innovation and to introduce the necessary incentives to grow the domestic market significantly given that 80% of the production is currently exported to Germany and the USA. The article addresses these issues by reviewing the recent technological and market trends in the Chinese PV industry. It also explains the major domestic manufacturing strategies and indicates the possible future direction of photovoltaic power generation in China. The study is based on personal interviews conducted in China from May to July 2005 with the major players along the solar supply chain, as well as with representatives of the Chinese photovoltaic R&D sector and policy makers.

When completed, the Bavarian Solarpark will count as one of the largest photovoltaic power plants in the world. With 57,600 solar panels covering a total of 25 hectares of farmland, the 10-megawatt peak station actually consists of three collector installations located within a 50 km radius. While the plant is expected to partially replace Germany's nuclear and fossil fuel power plants with homegrown solar PV plants, the losses due to transmission of central station solar power negate the benefits enjoyed by users of on-site solar generation. The ultimate goal, however, is to foster the growth of a global PV industry and to count on economies of scale to bring the price of PV down to levels that even developing countries can afford.  相似文献
