Introduction
• Solar Thermal power plants are used to generate electricity from the energy of the sun.
• Heliostats (mirrors) and a receiver located at the top of a tower are used.

Introduction
• Shading occurs when a heliostat casts its shadow on another heliostat located behind it.
• Blocking occurs when a heliostat in front of another heliostat, blocks the reflected suns energy on its way to the receiver.

Terms
• Heliostat - Movable mirrors that are used in the solar energy power plants.
• Grid - Pattern of mirrors represented in rows and columns.
• Cell - The number of mirrors arranged per square area in a structured way

Previous Capstone Work
• Implemented formulas to calculate the shading and blocking between the representative mirrors and the other mirrors.
• Developed a web application which calculates the levels of shading and blocking for a given grid arrangement at specified longitudes and latitudes.
• Stored the results obtained in a text file .

Problem Specification
• Verify the computation of shading and blocking for 8 mirrors done by the previous capstone team.
• Calculate shading and blocking for 24 mirrors.
• Use Java-3D software to show the graphical representation of levels of shading and blocking.
• Use slit mirror design to maximize the efficiency of heliostat setup.

Problem Specification
• Improve the previous capstone project by storing the results in a database
and provide an application to retrieve those results.
• Compute annual energy based on yearly insolation data .• Create a set of test cases.

Problem Specification• Calculate (x,y) coordinates of the neighboring mirrors to the central mirror
in the cell.
• Initially the minimal ∆R and ∆Az are calculated where ∆R = the radius of the circular rings in the field ∆Az = distance between the centers of two mirrors.

• ∆Az and ∆R are varied until we get minimal shading and blocking.

Implementation
• The mirrors are placed in a radial stagger way and the mirrors in each cell are
kept in the form of rhombus.
• The central mirror in a cell is considered as a reference mirror for calculating
shading and blocking.
• The distances between the mirrors are calculated with respect to the diagonal
length of the central mirror.

User Interface
Allows the user to populate the longitude and latitude values for a particular
location.
Enables the user to store the longitude and latitude of a new location.
A full scale web application instead of a webpage.
A more compact representation of the levels of shading and blocking through the
Java3D visualization interface.
