Customer ServicePhotovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.

Customer ServiceAl-Sayyab et al. found the optimum tilt angle for the photovoltaic cell located in northern Iraq for Arbil, Dahuk, Sulaymaniyah, and Kirkuk; the tilt angle varied in the range from0°to 90°. The results show the optimum tilt angle for Arbil is 34°, Dahuk is 34°, Sulaymaniyah is 33°, and Kirkuk is 33°.
This angle is only measured in the horizontal plane; in other words, it neglects the height of the sun. Angle of Incidence, θ: This is the angle between the line that points to the sun and the angle that points straight out of a PV panel (also called the line that is normal to the surface of the panel). This is the most important angle.
The tilt angle, defined asthe angle of PV arrays with respect to the horizontal, is a dominant parameter affecting the collectable radiation of a fixed PV array. Many studies focus on the effect of photovoltaic cell orientation and tilt on its performance; Soulayman et al. showed that optimum tilt angle is almost equal to the latitude.
Angle of Incidence, θ: This is the angle between the line that points to the sun and the angle that points straight out of a PV panel (also called the line that is normal to the surface of the panel). This is the most important angle. Solar panels are most efficient when pointing at the sun, so engineers want to minimize this angle at all times.
The critical angle for these rays is equal or above 21°–37°, depending on the material, structure, encapsulation and coating of the device. The MELA increases the solar conversion efficiency by increasing the optical interaction length within the solar panel by redirecting rays to induce total internal reflections.
However, exact orientation is of prime importance to allow a PV system to receive maximum irradiation . Two main angles are used to define array orientation: tilt angle and azimuth angle, wherein tilt angle is the vertical angle between the horizontal and the array surface .
