Module block fault locating strategy for large-scale photovoltaic arrays

Energy Conversion and Management, 2020
Abstract In practical grid-connected photovoltaic systems, faulty modules for small-scale photovoltaic arrays need to be accurately located, while the same strategy to locate each faulty module for large-scale arrays would imply high investment cost due to a large number of sensors needed.

A cell-to-module-to-array detailed model for photovoltaic panels

Solar Energy, 2012
Abstract This paper presents a modified current–voltage relationship for the single-diode model. The single-diode model has been derived from the well-known equivalent circuit for a single photovoltaic (PV) cell. A cell is defined as the semiconductor device that converts sunlight into electricity. A PV module refers to a number of cells connected in

Static concentrator photovoltaic module with prism array

Solar Energy Materials and Solar Cells, 2001
To obtain cost-effective photovoltaic modules, we have developed static prism-array concentrator modules consisting of prism concentrators about 4 mm thick assembled unidirectionally under a 3.2-mm-thick cover glass. Calculating the optical collection efficiency for the annual solar irradiation in Tokyo, we found that the theoretical efficiency of the ...

A proposed photovoltaic module and array mathematical modeling destined to simulation

2009 IEEE International Symposium on Industrial Electronics, 2009
Photovoltaic applications are increasing rapidly, thus, an accurate photovoltaic module modeling is requested in order to allow photovoltaic plants simulations. This paper presents a mathematical modeling to describe numerically photovoltaic modules and arrays, taking into account the radiation and temperature effects on output voltage, current and ...

Self-Cleaning Microcavity Array for Photovoltaic Modules

ACS Applied Materials & Interfaces, 2018
Development of self-cleaning coatings is of great interest for the photovoltaic (PV) industry, as soiling of the modules can significantly reduce their electrical output and increase operational costs. We fabricated flexible polymeric films with novel disordered microcavity array (MCA) topography from fluorinated ethylene propylene (FEP) by hot ...
