 The current experiment intends to study several factors that affect the characteristics, efficiency and power output of a particular photovoltaic panel. To achieve this, a fixed LED panel containing several RGB LEDs was used as the source of radiation for a photovoltaic panel, which can rotate and, consequently, vary the angle it makes with the LED panel. Furthermore, the load resistance connected to the photovoltaic panel can also be varied, enabling the study of how this quantity affects the voltage, current and power yielded by the photovoltaic panel.

 By changing the angle and keeping constant the lighting conditions, it is possible to verify how the power produced by the panel varies depending on the lighting angle. It is important to highlight that, in the experiment, the rays do not strike in parallel as in the solar radiation, so it is possible to define an effective angle that involves a slower tempo than the real angle.
-To determine the effective value of radiation, when adjusting a first sinusoidal model (using, for example, the cosine of the angle), the multiplicative factor of the angle must be discovered by the appropriate adjustment of the function. It is suggested to use a function <math> P_{ger} = A\cos(gain\cdot \theta)</math>, where the gain is of the order of unit but always greater. Looking at figure 3, with the panel at 90º, it still receives light. If the rays were parallel, it would be completely obscured.
