6 FAQs about [Photovoltaic panels series and parallel internal resistance]

What causes series resistance in a solar cell?

Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.

What are series and shunt resistances in solar cells?

Series and shunt resistances in solar cells are parasitic parameters, which affect the illuminated current–voltage (I–V) characteristics and effi ciency of cells. Very high values of series resistance (R s) and very low values of shunt resistance (R sh) reduce short-circuit current density (J sc) and open-circuit voltage (V oc), respectively.

How to analyze series resistance of solar PV modules?

The methods under consideration are: single slope method, one curve illumination method and mesh analysis. The interpretation of series resistance is done for 18 different solar PV modules containing CdTe, CIGS, mono-crystalline and multi-crystalline silicon modules. The reliability of this method under outdoor operating conditions is also studied.

What is a solar panel resistance?

Resistance is the opposition that a substance offers to the flow of electric current. There are various solar panel output parameters that can be measured and obtained during flash test, helping to judge on the performance quality of a solar panel.

How does series resistance affect the IV curve of a solar cell?

However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance. A straight-forward method of estimating the series resistance from a solar cell is to find the slope of the IV curve at the open-circuit voltage point.
