Photovoltaic panel parameter determination method

How to estimate unknown parameters of a PV cell/module?

In most of the studies the unknown parameters of a PV cell/module are estimated by minimizing an objective function. Usually, the objective function in most of the studies, minimizes the error, existing between desired and estimated characteristics, through some optimization techniques such as, Newton Raphson or Metaheuristic algorithms.

What is the mathematical structure of solar PV?

Several mathematical structure of solar PV, including single exponential model (SEM), double exponential model (DEM), fuzzy logic models, and ANN based model have already been studied in the research for the exact analysis of solar PV 1, 4. However, each of these models has their own merits and limitations.

How accurate is a current–voltage measurement method?

This method is accurate even in the presence of noise errors in measurement. The estimation of physical parameter values for PV modules or solar cells based on current–voltage experimental characteristics is very important in performance assessment and in simulation, design, and quality control studies.

How many state points does a photovoltaic cell have?

Peng, L., Sun, Y. & Meng, Z. An improved model and parameters extraction for photovoltaic cells using only three state points at standard test condition. J. Power Sourc. 248, 621–631 (2014). Huang, P. H., Xiao, W., Peng, J. C. H. & Kirtley, J. L. Comprehensive parameterization of solar cell: Improved accuracy with simulation efficiency.

What are the unknown model parameters of SEM?

where VT is the thermal voltage (= KT / q ), K is the Boltzmann constant, T is the temperature in Kelvin and q is the electron charge. The five unknown model parameters of the SEM are Ipv, Is, Rs, Rsh, and A. The major of estimation of these unknown parameters is the non-linear characteristics of (1).

Are solar PV systems a good source of electricity?

Nowadays, the solar PV systems are being recognized as the immerging and promising potential source of electrical power generation due to their characteristics, namely nondepletable, indigenous, flexible size, and virtually non-polluting.
