Solar Energy Power Plants.A parabolic through consists of a linear parabolic reflector that concentrates sun-light onto a receiver positioned along the reflector's focal line. The reflector follows the sun during the daylight hours by tracking along a single axis. The solar light is absorbed by the parabolic bended, single-axis reflectors and subsequently concentrated on the receiver-tube. As a direct result, the solar light tops the normal efficiency by 80. Caused by the reflection, the solar energy turns into thermal energy. The heat transfer fluid (usually oil), which is flowing through the receiver tubes, is then heated by the sun and reaches a temperature of 400°C. Therefore, the solar energy reaches the block-unit power station as thermal energy, where it is transformed into electrical energy. |
