PV Mounting body - Dissertation ExamplePV panels are installed at changeless angles. The angle is usually predetermined so that there is an optimum solar radiation being received, by the panel, throughout the year. Efficiency can be increase by attach the PV panels on a double axis, where two panels are mounted in such a way that they face away from for each one other, at an angle, as shown in figure 1 (Sampson 2009). This is opposed to a wholeness axis rise where the panel (or panels) is mounted on one military postureing of the mounting structure as shown in figure Double located rock and roll mounting formation is usually more expensive than single fixed tilt mounting system because double fixed tilt mounting structures require more materials than their single mounting counterparts do. However, double fixed tilt mounting system results to higher PV performance since the panels ikon to solar radiation is higher than in single fixed tilt mounting systems.Azimuth (Sun Tr acking) PV Mounting SystemThis mounting system aims at maximizing panels exposure to the sun, which results into an increase in power output. It is essentially a combination of the single and double axis fixed tilt mounting systems whereby an automatic adjustment system makes a single axis fixed tilt mounting system course like a double axis mounted fixed tilt mounting system. The automatic adjustment system changes the panels angle with find to the suns position, in the sky, and the PV array as shown in figure 3. There are two mounting arrangements under the azimuth mounting system single axis and double axis tracking system. In the single axis sun tracking system, the panel is adjusted with respect to the suns East-West movement only (single axis). On the other hand, in double axis tracking system, the panel is usually adjusted along two axes, the east-west suns movement and the seasonal shifts in suns position. In other words, the double axis tracking system adjusts the panels w ith respect to suns position in the sky throughout the year (Sampson 2009). Figure 3 Azimuth PV mounting system (Sampson 2009) The azimuth PV mounting system offers power advantages compared to the fixed tilt mounting system although it is much more expensive than the fixed tilt mounting system due to its complexity. Due to their low initial and operation costs, single axis fixed tilt PV mounting systems are often used for home application (Glasnovic and Margeta 2009 1144). In addition, single axis fixed tilt mounting systems are easy to install because they only require a mounting frame that is tilted at an angle and a PV securing system. However, power output is usually minimal, which may require people to use panels that are of a higher capacity than their domestic needs to ensure that enough power is collected during the exposure time, which is often a fraction of the daylight (Glasnovic and Margeta 2009 1144). Otherwise, power collected during
