“…On the contrary, Fig. 3 shows that the change in solar radiation directly affects the short circuit current while there is no significant impact on the open circuit voltage (Bharath et al, 2016;Selmi et al, 2014). Accordingly, the approximate short circuit current at any solar radiation (G) can be given as Tan et al (2013) and Rahman et al It is evident from the previous discussions that the short circuit current represents an excellent factor which can be utilized to estimate the solar radiation required for monitoring and controlling of the PV system.…”

This study presents an accurate solar radiation estimation method based on the relationship between the solar radiation and the short circuit current of the PV panel. In order to avoid the interruption of the generated power of the PV panel during the solar estimation period an auxiliary PV panel fixed in the same alignment with other PV panels is used to estimate the solar radiation. The proposed method is implemented and tested using a 3W poly-crystalline PV panel PSP3 and a microcontroller (Arduino Uno). Test results verified the accuracy of the proposed method for several solar radiation cases.

“…The first continuously track voltage and current, in order to dynamically adjust the power operation point, without the need for any empirical information. Algorithms like perturb and observe (P&O), incremental conductance (IC), or hill climbing (HC) belongs to this category [47][48][49] and are characterized by high hardware, complexity, continuous functionality, and high efficiency, especially if the behavior of the energy source is unknown. Other MPPT techniques like fractional open-circuit voltage (FOCV) or fractional short-circuit current (FSCC) requires less complexity and measured data, without the need of continuously track the input voltage and/or current since they rely on a priori information about the source [50,51].…”

In this work, an identification technique of a simple, measurements-based SPICE (Simulation Program with Integrated Circuit Emphasis) model is presented for small low-cost Peltier cells used in thermoelectric generator (TEG) mode for low-temperature differences. The collection of electric energy from thermal sources is an alternative solution of great interests to the problem of energy supply for low-power portable devices. However, materials with thermoelectric characteristics specifically designed for this purpose are generally expensive and therefore often not usable for low cost and low power applications. For these reasons, in this paper, we studied the possibility of exploiting small Peltier cells in TEG mode and a method to maximize the efficiency of these objects in energy conversion and storage since they are economical, easy to use, and available with different characteristics on the market. The identification of an accurate model is a key aspect for the design of the DC/DC converter, in order to guarantee maximum efficiency. For this purpose, the SPICE model has been validated and used in a design example of a DC/DC converter with maximum power point tracking (MPPT) algorithm with fractional open-circuit voltage. The results showed that it is possible to obtain a maximum power of 309 µW with a Peltier cell 2 × 2 cm at a ΔT of 16 °C and the designed SPICE DC/DC converter performance proved the improvement and optimization value given by the TEG model identification.

Quite often PV modules operate in mismatch conditions, that are caused by: technology, design, installation and operative conditions. As far as the operative conditions are concerned, shading mainly causes uneven distribution of irradiance on PV cells, in turn shading creates not uniform distribution of temperature on the PV modules. There are also situation where the uneven distribution of temperature is a design input such as in the solar hybrid photovoltaic/thermal (PV/T) system. In this context a Matlab/Simulink model of a PV array able to cope with these problems has been developed. The model has been tested both numerically and experimentally. Finally an application of this tool to the analysis of a PV/T system is reported and discussed. The evaluation of power losses is used to choose an optimal design of a PV/T system.
