About Photovoltaic panel parallel resistance
This is also identified as real single diode model with series resistance (Rs) and parallel resistance (Rp). Ideally Rs and Rp are ignored but in reality it is not possible to overlook these resistances, because efficiency of the PV solar cell is affected by these parameters ( Villalva et al., 2009 , Pandiarajan and Muthu, 2011 , Rekioua and .

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.
The block provides the following relationship between the parallel resistance R p and the solar cell temperature T: R p ( T ) = R p * ( T T m e a s ) T R P 1 where TRP1 is the Temperature exponent for Rp, TRP1 parameter value.
The following figure shows a schematic of series, parallel and series parallel connected PV modules. PV Module Array. To increase the current N-number of PV modules are connected in parallel. Such a connection of modules in a series and parallel combination is known as “Solar Photovoltaic Array” or “PV Module Array”.
The investigated study reveals the significant impact of temperature on the efficiency of solar PV systems. Furthermore, it shows that the parallel configurations (Total-Cross-Tied, Honey-Comb, and Bridge-Linked) of photovoltaic panels enhance the photovoltaic system's performance, contrary to the serial configurations (Series, Series-Parallel).
