Effect of temperature and radiation on the parameters of photovoltaic modules

Abstract

This work evaluates the influence of temperature and irradiation on the behavior of mono-crystalline silicon, poly-crystalline silicon, and Copper Indium diselenide (CIS), modules which have been exposed to real conditions. An outdoor experimental setup has been installed, at a Mediterranean site in north latitude 38 °, in order to collect results from current-voltage measurements that corresponded at constant radiation level in order to evaluate the effect of temperature and results from measurements realized at about the same temperature in order to study the effect of irradiation. The results present that the daily generated power normalized to the manufacturer's value is positively influenced by the irradiation and not by the negative effect of temperature. The performance of mono and poly Si appears superior to that of CIS early in the morning, while this advantage is diminished during midday, when the temperature and irradiance are highest, as CIS performance becomes comparable to the other two. However, the temperature affects the efficiency and fill factor for the mono and poly-Si modules recording the lower values on higher temperatures, while it does not the same for the CIS modules. This experimental study can provide information for locations with similar climatic conditions because it helps to take into account variation in temperatures together with variation in radiation and to avoid under-designing of photovoltaic systems and system malfunction.

“…However, as a result of the higher temperatures and radiation, this was diminished by midday. It was also observed from these tests that the short-circuit current (I sc ) increased for the three types of modules only when temperatures increased, and that increasing irradiance had a positive effect on the I sc , open circuit voltage (V oc ), and maximum output power (P max ) in all modules [13].…”

Tests were performed on 92 series-connected cells under the influence of variable irradiation and temperature [14].…”

“…The impacts of changes in solar irradiation on seven parameters of the two-diode model have been studied, based on the levels of solar irradiation at the standard maximum power point (MPP) test conditions. Computing the values of the seven parameters at various levels of irradiation was carried out using the Runge-Kutta-Merson numerical analysis method [12].The effects of irradiance and temperature on the behavior of single-crystal silicon (mono c-Si), polysilicon (poly-Si), and copper indium diselenide (CIS) solar cells were studied in [13]. The results showed remarkable superiority of mono c-Si and poly-Si cells in the early morning compared with CIS modules.…”

Performance Evaluation of Various Photovoltaic Module Technologies at Nawabshah Pakistan

“…The PV module temperature coefficients reported by different researchers and manufacturers for polycrystalline modules were minus 0.40 %/°C (King et al 2002) and 0.64 %/°C (Perraki and Kounavis 2016). Whereas, for monocrystalline modules were minus 0.39 %/°C (Perraki and Kounavis 2016) and 0.50 %/°C (King et al 2002). Similarly, for amorphous modules were minus 0.10%/°C (Gaur and Tiwari 2014) and 0.25 %/°C (King et al 2002), and for thin module was minus 0.24 %/°C (Clean Energy Project Analysis 2004).…”
