Bottom Line: A new, simple, and quick-calculation methodology to obtain a solar panel model, based on the manufacturers' datasheet, to perform MPPT simulations, is described.The method takes into account variations on the ambient conditions (sun irradiation and solar cells temperature) and allows fast MPPT methods comparison or their performance prediction when applied to a particular solar panel.The feasibility of the described methodology is checked with four different MPPT methods applied to a commercial solar panel, within a day, and under realistic ambient conditions.

ABSTRACT
A new, simple, and quick-calculation methodology to obtain a solar panel model, based on the manufacturers' datasheet, to perform MPPT simulations, is described. The method takes into account variations on the ambient conditions (sun irradiation and solar cells temperature) and allows fast MPPT methods comparison or their performance prediction when applied to a particular solar panel. The feasibility of the described methodology is checked with four different MPPT methods applied to a commercial solar panel, within a day, and under realistic ambient conditions.

Solar panel temperatures on May 13, 1971 (a), and May 14, 1971 (b), at the Goddard Space Flight Center (GSFC). These graphs were calculated according to ambient conditions for those days; see Figure 5 and (17).

Mentions: With the data of Figure 5 regarding sun irradiance and ambient temperature it is possible to calculate temperature of the solar panel with the equation(17)Tp=Ta+G800NOCT−20°C,where Ta is the ambient temperature, G is the irradiance level, and NOCT is the open-circuit module operation temperature at 800 W/m2 irradiance, 20°C ambient temperature, and 1 m s−1 wind speed. This last parameter is normally included in the manufacturers' datasheet. Although some authors take wind speed variations into account [49], in the present work they are not considered, as a constant thermal loss coefficient is assumed for wind speeds higher than 1 m s−1. Making use of (17), combined with the data from Figure 5, temperature of solar panels located at the Goddard Space Flight Center (GSFC) on March 13 and March 14, 1971, can be estimated; see Figure 6.
