The AIST 1 MW PV facilities consist of a total of 211 inverters of the 4-kW type designed principally for residential uses, and tens of inverters of the 10-kW unit designed principally for industrial uses. These inverters are connected to low-voltage (200 V) distribution line in AIST. There are 13 kinds of PV modules from 5 different technologies and tens kind of PV inverter from several manufactures. Benchmarking these PV components reveals the differences of the performance and reliability among other PV components under actual conditions. During the first two years, there were several failures in the system components, mainly caused by improper installation works. But the PV facilities showed proper performance ratio (around 70%) and perfect availability in total. The mean time of failure was 7.9 times. More than 64% of individual PV systems had no failures. The mean time to repair was only 3.3 days

The use of appropriate performance parameters facilitates the comparison of grid-connected photovoltaic (PV) systems that may differ with respect to design, technology, or geographic location. Four performance parameters that define the overall system performance with respect to the energy production, solar resource, and overall effect of system losses are the following: final PV system yield, reference yield, performance ratio, and PVUSA rating. These performance parameters are discussed for th...

ABSTRACT: large-scale Spanish photovoltaic plants is presented. 20 installations, totalling more than 90 MW, are analysed for a period of up to 4 years. We suggest a procedure to assure the consistency of the data coming from the field and a method of calculating the energy availability rate of the installations, both of them in a way that is independent of the operator of the plant. The operational results are final yields of more than 1,500 kWh/kW for static installations and more than 2,100 k...

Although the solar energy industry has experienced rapid growth recently, high-level management of photovoltaic (PV) arrays has remained an open problem. As sensing and monitoring technology continues to improve, there is an opportunity to deploy sensors in PV arrays in order to improve their management. In this book, we examine the potential role of sensing and monitoring technology in a PV context, focusing on the areas of fault detection, topology optimization, and performance evaluation/data...

Photovoltaics (PV) is an important and rapidly growing area of research. With the advent of power system monitoring and communication technology collectively known as the “smart grid,” an opportunity exists to apply signal processing techniques to monitoring and control of PV arrays. In this paper a monitoring system which provides real-time measurements of each PV module's voltage and current is considered. A fault detection algorithm formulated as a clustering problem and addressed using the r...

Currently, the know-how and experience concerning the behavior and reliability of large tracking photovoltaic (PV) plants is scarce. Information such as the availability rate is rarely known. Acciona Solar PV plants installed in Navarra (Spain) in the frame of the Spanish utility grid constitute a representative source of information. The scope of this study is to analyze in detail the behavior along 2006 of six of these plants, located in Arguedas (two plants of a rated nominal power of 940 kWp...

This paper introduces a method for designing a standalone photovoltaic system to improve the load point reliability, extend the operation life, and minimize the design cost. This approach examines the impacts of solar panel sizes, tilt angles and battery volumes toward load point reliability, as well as the expected system life, by using real insolation data in a given location and random load burdens. The reliability evaluation incorporating solar insolation variations and load point uncertaint...
