The efficiency of low temperatures solar thermal systems such as flat plate collector (FPC), evacuated tubular collector (ETC), solar pond (SP), and solar chimney (SC) are in the order of 15–40% and the medium temperature solar systems such as linear Fresnel reflector (LFR) and parabolic trough collector (PTC) are in the order of 50–60%.
Their results revealed that the electrical and thermal efficiencies of the combined system were 6.7 % and 33 %, respectively, compared to 7.2 % for a conventional standalone PV panel and 54 % for a conventional standalone solar-thermal collector.
Kalogirou (2003) analyzed the characteristics and economics of solar thermal energy systems such as flat plate, evacuated tubular, compound parabolic, and parabolic trough collectors for industrial applications such as paper, textile, chemical, food, and beverage industries (temperature range from 60 °C to 260 °C).
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors.
In the world of renewable power generation technologies, solar thermal power generation faces stiff competition from solar PV and wind energy systems. The latter two systems are not just more technologically mature, but also cheaper than the former.
The integration of solar thermal energy systems with the industrial processes mainly depends on the local solar radiation, availability of land, conventional fuel prices, quality of steam required, and flexibility of system integration with the existing process.
