Typically, solar panels are installed on rooftops or mounted on frames, allowing them to be adjusted to the desired angle. The optimal orientation depends on factors such as the geographical location, season, and time of day. When solar panels are angled towards the sun, they are able to capture the maximum amount of sunlight, resulting in higher efficiency. Conversely, if their orientation is not proper, they will receive less sunlight and produce less electricity. In the northern hemisphere, solar panels are commonly installed facing south in order to capture the most sunlight throughout the day. Conversely, in the southern hemisphere, solar panels are oriented towards the north. This orientation allows the panels to receive sunlight for the longest duration during the day. The tilt angle of solar panels also affects their performance. Typically, the ideal tilt angle is equal to the latitude of the installation location. However, this angle can be adjusted to optimize energy production in different seasons. For example, in winter, the panels can be tilted at a steeper angle to capture more sunlight, while a shallower tilt angle in summer can prevent overheating. Improperly oriented solar panels can significantly reduce their performance, resulting in lower energy output. Therefore, it is crucial to consider the orientation and tilt angle when installing solar panels to ensure maximum efficiency and optimal energy production.
