Novel modeling approach for photovoltaic arrays
2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS), 2012This paper proposes high accuracy modeling approach for photovoltaic (PV) arrays. I–V characteristic of PV cell is described by nonlinear equation that's complicated to be solved by the ordinary mathematical methods. The main theme of this contribution is to use a robust algorithm to solve for all single diode model parameters.

Temperature dependence in modeling photovoltaic arrays
2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013Photovoltaic (PV) array output varies with environmental conditions. In this paper, an improved algorithm is proposed to model PV arrays at temperatures different than the nominal temperature. The proposed model is validated with experimental data of Kyocera KC200GT multi-crystalline silicon solar array.

Pspice Modelling of Photovoltaic Arrays
International Journal of Electrical Engineering & Education, 1995PSPICE modelling of photovoltaic arrays A detailed model of a photovoltaic array written in PSPICE is presented in this paper. The powerful graphics post-processor that accompanies the software program is used to display array characteristics as a function of certain parameters such as insulation and temperature.

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

Simulation of large photovoltaic arrays
Solar Energy, 2018Abstract Large photovoltaic arrays are becoming common as the world moves to replace fossil-fuelled electricity generators. As the array size and project cost increase, it becomes increasingly important to know accurately what the array’s performance will be before it is built.

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.

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.

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 ...

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 ...
