According to the Law of Reflection, the angle of reflection equals the angle of incidence.

The most detailed expression of the model fits with high degree of accuracy the local AAL data, the second version consists of a global term plus a local weather-descriptive one, and the third version is a universal global model dependent only on the latitude and the PV module tilt angle. The second ray reflects off the boundary before propagating to point 2. The model has three different versions that are to be used depending on the availability of the local radiation data. To calculate the angle of refraction of an incident ray entering a raindrop enter: The refractive index of air for a ray with wavelength 589.29 nm.

From the analysis of the results, we propose an easy-to-use mathematical expression for the calculation of AAL. From the law of reflection, thetaithetar, where thetai is the angle of incidence. In this paper we have used this model to calculate AAL in an hourly basis at 79 different sites all over the world and considering ten different tilt angles, from horizontal to vertical, for south (north) oriented PV modules at north (south) hemisphere sites. The angle of reflection thetar of a ray or beam is the angle measured from the reflected ray to the surface normal.

I am told that the phase angle of 39.81 is derived from the complex reflection coefficient, and I understand that the reflection coefficient must be complex, but I simply calculate it as 0.128 and dont understand how to derive it as a complex number. Instantaneous angular losses (AL) can be calculated by using an analytical model, formerly developed by the authors, that has proved to be in good agreement with the experimental data. However, my professor has given the answer as 39.81.

The way to use these programs is shown below: For s-polarized. The objective of this work is to obtain a universal model for calculating the annual angular reflection losses (AAL) of PV modules working in real conditions, useful in the prediction or assessment of the annual performance of PV systems. They calculate the amplitude reflection/transmission coefficients, reflectance and transmittance.
