The document discusses solar tracking systems and their practical applications. A solar tracking system adjusts the orientation of solar panels to follow the sun's movement throughout the day, maximizing energy production. A single-axis tracker rotates panels along one axis, typically north-south, and can increase energy output by 10-25% compared to fixed panels. Solar trackers are used to align photovoltaic panels, reflectors or lenses toward the sun, since the sun's position changes with seasons and time of day. Their goal is to optimize the angle of collection and maximize captured solar energy.

2. TOPIC OUTLINE
What is Solar Radiation Data?
Practical Applications
A typical solar tracking system adjusts the
face of the solar panel or reflective surfaces
to align with the sun as it moves across the
sky. The system moves though one rotation
per day. It is this relatively slow motion that
enables the time-compression approach for
ALT.

3. INTRODUCTION
A solar tracking system maximizes your solar
system's electricity production by moving
your panels to follow the sun throughout the day,
which optimizes the angle at which
your panels receive solar radiation.
A single-axis tracker moves your panels on one
axis of movement, usually aligned with north and
south.

As the names imply, a single-axis tracker
rotates a row or many rows of panels
along an axis.
This design is suitable for moderately
sized residential solar installations all the
way up to very large utility scale
installations.
This design typically delivers from 10% to
25% more energy when compared to the
equivalently sized fixed-tilt ground
mounted solar energy system.

5. Solar trackers are devices used to
orient photovoltaic panels, reflectors,
lenses or other optical devices toward
the sun.
Since the sun's position in the sky
changes with the seasons and the
time of day, trackers are used to align
the collection system to maximize
energy production.
