Solar Panel Orientation And Tilt

The tilt angle or elevation angle describes the vertical angle of your solar panels.

Solar panel orientation and tilt.

On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The following table gives the best dates on which to adjust. The decision of azimuth. The angle of the sun varies throughout the year as illustrated in figure 9.

Solar panels should face directly into the sun to optimize their output. Orienting the pv panel in a direction and tilt to maximize its exposure to direct sunlight will optimize the collection efficiency. The panel will collect solar radiation most efficiently when the sun s rays are perpendicular to the panel s surface. The angle or tilt of a solar panel is also an important consideration.

Solar panels should always face true south in the northern hemisphere north in the southern hemisphere tilted from the hoizontal at a degree equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. In this case for the solar panels to get their best performance a steep angle of 60 is best. An additional 3 5 though can be gained by evaluating this more carefully.

If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you. In china usually the azimuth of solar panel is orienting due south to guarantee the maximum power generation from solar. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. The angle that a solar panel should be set at to produce the most energy in a given year is determined by the geographical latitude.

For the best results solar panels should be oriented towards the south. The tilt is 0 if solar panel parallel to horizon to design the tilt is 90 if the solar panel is vertical to design. What angle for solar panels should be chosen to maximize the production all year long. Azimuth angle is their horizontal facing in relation to the equator.

This is because the sun is always in the southern half of the sky in the northern hemisphere. During the spring the best angle is 45 and during the summer when the sun is high in the sky it s best to have a low tilt at 20. The orientation of solar module may be defined by two parameters namely azimuth and tilt angle figure 2. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.
