1. Introduction
Solar power plants: It has a centralized receiver which produces electrical power by converting the sun’s energy in to high temperature heat using various mirror (heliostats) configurations
Central receiver technology for generating electricity has been demonstrated in the solar one pilot power plant at Barstow, California
2.1 Heliostats
The heliostat is composed of several mirror modules rather than having single large mirror
2.2 Receiver - Tower
The receiver, placed at the top of a tower, is located at a point where reflected energy from the heliostats can be intercepted more efficiently There are two basic types of receivers
1. External
2. Cavity
2.3 Field Layout
Best position for locating heliostat relative to the receiver
How high to place the receiver above the field
Field layout depends on the following loss mechanisms
1. Cosine effect
2. Shadowing and blocking
Shadowing and BlockingShadowing occurs at low sun angles when heliostat casts its shadow on a heliostat located behind itBlocking can be observed in a heliostat field by noting reflected light on the backs of heliostats
