EVALUATION OF A PARABOLIC TROUGH COLLECTOR PERFORMANCE

2012
In this paper the collector erected at the Archimedes Solar Energy Laboratory is initially presented followed by the performance evaluation of the collector. The collector is made by Nep Solar from Australia. It has an aperture area of 14.4 m2, a concentration ratio of 13.7 and can be operated up to 200°C.

Designing an Innovative Secondary Optics for Parabolic Trough

Proceedings of the ISES Solar World Congress 2015, 2016
A secondary optics for CPV parabolic troughs was developed to reduce the photovoltaic cells number. The proposed solution is a cylindrical Fresnel lens that transforms the focal line into a series of focal points. Its insertion inside the Concentrating PhotoVoltaic trough increases the solar concentration keeping unchanged the total collection ...

Basic Control of Parabolic Troughs

2012
The chapter outlines the main features of the different modeling and basic control approaches used during the last 25 years to control the distributed collector systems (DCS). The DCS may be described by a distributed parameter model of the temperature.

Optical performance of a composite parabolic trough

Applied Energy, 1985
Abstract The effects of receiver misplacement and the trough pointing towards the sun on the concentration characteristics of a composite parabolic trough are discussed. Results from some numerical calculations are presented graphically and discussed.

Optimization of parabolic trough solar collectors

Solar Energy, 1982
Abstract The results of a detailed optical analysis of parabolic trough solar collectors are summarized by a few universal graphs and curve fits. These graphs enable the designer of parabolic trough collectors to calculate the performance and optimize the design with a simple hand calculator.
