Determination of error tolerances for the optical design of parabolic troughs for developing countries

Parabolic trough concentrators—design, construction and evaluation

A method for the design of parabolic trough collectors for different environments (economic, technical, geographic) with different constraints and set or objective, it presented This method, in addition to the usual performance related parameters, has Options to include and process qualitative and/or quantitative intimation about the technology level of the environment and type of application, thereby, enabling the designer to cope with change in an efficient manner.

Reexamining the Prospects for Solar Industrial Process Heat

The potential performance of single-axis tracking parabolic trough solar collectors as a function of optical energy distribution and receiver size has been calculated for eleven sites using typical meteorological year input data. A simulation based on the SOLTES code was developed which includes the three-dimensional features of a parabolic trough and calculates the thermooptical tradeoffs. The capability of the thermooptical model has been confirmed by the comparison of calculated results with the experimental results from an all-day test of a parabolic trough. The results from this eleven-site analysis indicate a potential performance superiority of a north-south horizontal axis trough and, in addition, a high quality (optical error, sigma/sub system/ less than or equal to 0.007 radian) collector should be of the same geometric design for all of the sites investigated and probably for all regions of the country.
