Over the past five years, the cost of solar panels has dropped drastically and, in concert, the number of installed modules has risen exponentially. However, solar electricity is still more than twice as expensive as electricity from a natural gas plant. Fortunately, wire array solar cells have emerged as a promising technology for further lowering the

Photovoltaic array loss mechanisms
Solar Cells, 1986Loss mechanisms which come into play when solar cell modules are mounted in arrays are identified. Losses can occur either from a reduction in the array electrical performance or with nonoptimal extraction of power from the array. Electrical performance degradation is caused by electrical mismatch, transmission losses from cell surface soiling and ...

Retractable planar space photovoltaic array
IEEE Conference on Photovoltaic Specialists, 2002An advanced array design based on the recently developed HS-601 oriented flatplate array is described. The advanced design incorporates the use of high-efficiency gallium arsenide on germanium dual-junction solar cells that have BOL (beginning-of-life) efficiencies of greater than 22%. Reflections off deployable flatplate shutters increase the sunlight

1985
Two basic types of photovoltaic (PV) array simulator have been designed and tested. The first involves the use of a pilot panel and variable light source. It is implemented with analogue circuits. A stability analysis based on Popov's method is presented for this simulator with resistance-inductance (R-L) loads.

Fault diagnosis in photovoltaic arrays
2015 International Conference on Clean Electrical Power (ICCEP), 2015This paper proposes a simple automatic technique for fault diagnosis in photovoltaic (PV) arrays, based on the analysis of the an omalies observed in the I-V characteristic. Firstly, the I-V characteristic of the PV array is simulated using Matlab/Simscape tool for different faulty conditions; which is experimentally validated by generating different ...

Photovoltaic Array Reliability Optimization
IEEE Transactions on Reliability, 1982Several statistical reliability studies have been conducted in areas of photovoltaic component design covering cell failure, interconnect fatigue, glass breakage and electrical insulation breakdown. This paper integrates the results from these studies and draws general conclusions relative to optimal reliability features for modules.

Connection losses in photovoltaic arrays
Solar Energy, 1980Abstract The short-circuit current, open-circuit voltage and connection losses of arrays of solar cells, either for normal or concentrated sunlight are analysed under either series of parallel connection. The parameters of the individual cells are considered as random variables.

Performance prediction of photovoltaic arrays
2017 52nd International Universities Power Engineering Conference (UPEC), 2017The most important investment decision when it comes to implementing photovoltaic (PV) array(s) either for commercial or private application, is the levelized cost of energy (LCOE) calculation. Whereas LCOE, used as an assessment tool, to calculate the cost effectiveness of energy generation in relation to the return over investment in a prescribed ...

Self-Cleaning Microcavity Array for Photovoltaic Modules
ACS Applied Materials & Interfaces, 2018Development 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 ...
