Seasonal Solar Bracket Drawing

How do you pin-point the sun's position on a Sky Dome?

To pin-point the sun’s position on the sky dome, we need to make two measurements. The first measurement is the sun’s direction on a compass. A straight line drawn from the sun to the horizon intersects a specific degree on a compass. This angle is a measure of the sun’s azimuth or elevation.

How does a ground mount solar rack work?

This means you can find the angle that works best for your geographic location, elevation, and unique sun exposure. You also have the option to choose and install the Ground Mount Solar Rack as an adjustable system, which allows you to alter the angle according to the season and the sun’s position in the sky.

How does incoming solar radiation affect the seasons?

The amount of incoming solar radiation, or insolation, along with daylength influence the Earth’s seasons. In this lab, we will study the relationships between the Earth and the Sun and how those relationships influence the seasons we experience every year. This relationship results in what is known as the Annual March of the Seasons. Part A.

How can we chart the sun's position in a day?

With the help of these two arc lines, we can chart the sun’s position at any time in a day, during the year, at a given location on the earth’s surface. On December 21st, 9.00 a.m., the sun has risen in the east and is low in the southern sky. On June 21st, at the same time of the day, it is higher in the sky.

What is a solar window in the summer solstice arc?

Part of the summer solstice arc and winter solstice arc along with the 9.00 a.m. and 3.00 p.m. arc’s make the four sides of the rectangle. The area inside this rectangle is called the solar window for a given location. This solar window is very important because, it is between 9.00 a.m. and 3.00 p.m. that we receive the maximum energy from the sun.

What are the motion requirements for a solar tracker?

Since the solar path varies according to the location on earth, as shown in the example path charts in Fig. 3, the motion requirements for a solar tracker can significantly vary depending on where the panel is installed, with more demanding requirements closer to the Equator.
