High-temperature collectors are parabolic dish and trough collectors used primarily by utilities and nonutility power producers in the generation of electricity for the grid. High-temperature solar thermal collectors, which operate at temperatures higher than 180°F, are used primarily for R&D projects.
From 2002 to 2007 the thermal performance of solar collector has been increased by 29%, 39%, 55% and 80% for a mean solar collector fluid temperature of 40 ̊C, 60°C, 80°C and 100°C respectively. The increase of thermal performance is more significant for an increased solar collector fluid temperature.
The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non- water heating devices such as solar cookers or solar air heaters. Solar thermal collectors are either non-concentrating or concentrating.
High-temperature solar is concentrated solar power (CSP). It uses specially designed collectors to achieve higher temperatures from solar heat that can be used for electrical power generation. In this chapter, we discuss different configurations of concentrating collectors and advancements in solar thermal power systems.
The collector is tested with four mean solar collector fluid temperature levels: 22 ̊C, 40-49 ̊C, 68 ̊C and 87-89 ̊C. During the measurement, the average ambient air temperature is 14.7 ̊C. The average wind speed at the same height of the collector panel is 1.2 m/s.
Flat plate solar thermal collectors can deliver medium-temperature hot water suitable for delivery to radiant slabs. Concentrating collectors can provide hotter temperature water for baseboard radiators.
