Solar Radiation Concentrating Technologies use large mirrors to concentrate sunlight onto a relatively small-aperture receiver. Solar Radiation Concentrating Technologies use large mirrors to concentrate sunlight onto a relatively small-aperture receiver. Linear Fresnel Reflector Systems use long, narrow, flat or slightly curved mirrors that reflect Sun’s rays onto a fixed linear receiver mounted above and along them. Even in small scale, they usually adopt one-axis tracking mechanisms. Therefore, as incident solar rays are generally oblique, it is inevitable for these Systems to not have optical losses: cosine effect, end losses, shading or blocking effects. Thus, although they have some advantages compared with other technologies (simplicity, robustness and low capital cost), they also have important drawbacks and limitations that significantly limit their efficiency.
