“…Applying Kirchoff's current law at Node 1 in Fig. 2 b , the output current of the PV panel is expressed as [23–25]

I_{PV} = I_{LG} - I_{D} - I_{R_{SH}},

where I LG is the light generated current, I D is the diode current, and

I_{R_{SH}}

is the current of the equivalent shunt resistance. These parameters are given as

I_{LG} = I_{SCR} \frac{G}{1000 normalW / m^{2}} + J_{normalo} (T_{normalc} - T_{ref}),

I_{D} = I_{o} (][, \exp (}{, \frac{q false(V_{PV} + N_{s} R_{s} I_{PV} false)}{n k T_{c} N_{s}}) - 1),

I_{R_{SH}} = \frac{V_{PV} + N_{s} I_{PV} R_{s}}{R_{SH}},

where I SCR is the short circuit current at the reference state; G is the solar irradiance; J o is the temperature coefficient; T c is the cell temperature; T ref is the reference temperature; I o is the inverse saturation current; q is the charge of electrons; N s is the number of PV cells in series; n is the diode quality factor; k is the Boltzmann constant; R s is the equivalent series resistance; I PV is the PV panel current and V PV is the PV panel voltage.…”

“…Despite of the availability of other MPPT techniques, Perturb and Observe (P&O) algorithm is still the most common and broadly used due to its simplicity and low cost implementation [1], [3][4], [13][14][15][16][17][18]. Besides, it can be used practically in microcontroller or Digital Signal Processing System.…”

Solar energy is becoming popular and has drawn lots of attention from researchers nowadays. However, the output power of the photovoltaic (PV) arrays varies with solar irradiation and temperature, which affect the efficiency of PV arrays. Therefore, Maximum Power Point Tracking (MPPT) IntroductionFulfilling the energy demand from the people all over the world would be not enough if the energy sources are only limited to utilization of non-renewable sources such as fuel, gas and coal. Besides, most non-renewable energies cause pollution and less non-environmentally friendly. Hence, renewable energies are introduced in the past two decades to fulfill the energy demand. One of the popular renewable energies is solar energy which is extracted by converting sunlight into electrical power using the photovoltaic system. However, the conversion efficiency is relatively low with the range of only from 12% up to 20%, and it is highly dependent on the solar irradiation and panel temperature [1]. Thus, in this paper, Maximum Power Point Tracking (MPPT) control technique is explained which can increase the efficiency of the overall Photovoltaic (PV) system by extracting the maximum available power from the PV arrays [1][2][3].There are many MPPT techniques that have been introduced and elaborated extensively by researchers. Reference [4] stated that at least 19 distinct methods have been promoted, developed and implemented to improve solar photovoltaic. Each method differs in theirs complexity, number of sensors used, cost and effectiveness.The simplest technique that can be used is fixed duty cycle method [5] since it does not need any feedback to be implemented; but when the operation environment changes, the efficiency will become low. Fractional open circuit voltage (OCV) and fractional short circuit current (SCC) are also said to be the easiest offline methods for MPPT [3,4], [6][7][8]. As for the OCV method, the voltage at MPP (V MPP ) is approximately equal to the open circuit voltage (V OC ) of PV array with the factor of k 1 such that V MPP ≈ k 1 V OC , where k 1 ranges between 0.71 and 0.78 [9]. Similar with SCC method, the current at MPP (I MPP ) is approximately linearly related to the short circuit current (I SC ) of PV array, such that IMPP ≈ k 2 I SC, where k 2 ranges between 0.78 and 0.9 [4]. Regardless of their simplicity, the Maximum Power Point (MPP) obtained from these methods is not true due to the imprecise MPP tracking. Plus, the constants k 1 and k 2 are not valid during partial shading condition. It have been improved by sweeping the PV array voltage or current in order to update k 1 and k 2 , respectively. However, sweeping leads to complexity and incurs more power loss.
