Types of solar concentrators with examples
However, their efficiency is somewhat lower, as the flat design does not concentrate light as precisely as a parabola. These concentrators require less maintenance, but like parabolic troughs, they depend on direct sunlight. Linear Fresnel concentrators typically reach temperatures between 250°C and 300°C and are of a somewhat simpler design.
