Solar energy conversion technologies may be broadly classified into solar photovoltaic (PV) and solar thermal energy systems. Solar PV systems convert solar radiation into electricity directly and thermal systems convert solar radiation into heat.
The main applications of solar-thermal conversion technology in wastewater purification, seawater desalination, sterilisation and power generation were discussed. This work also summarised the two collection methods of fresh water after SCSG steam production and highlighted their advantages and disadvantages.
Heat energy is preferred as compared to electrical energy to meet the energy requirement of various applications in the process industries. Therefore, the solar thermal energy system is considered to be one of the attractive solutions for producing thermal energy for process heat applications.
The thermal conversion process of solar energy is based on well-known phenomena of heat transfer (Kreith 1976). In all thermal conversion processes, solar radiation is absorbed at the surface of a receiver, which contains oris in contact with flow passages through which a working fluid passes.
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.
In this article, an extensive review of various solar thermal energy technologies and their industrial applications are presented. The following industries are covered: power generation, oil and gas, pulp & paper, textile, food processing & beverage, pharmaceutical, leather, automotive, and metal industries.
Energy Transfer and Conversion Methods
Historic Energy Conversion Sequences • Biomass → heat (esp. cooking) • Solar → heat, dry clothes, dry food – Solar is still main light source, no need for conversion – Solar is source of biomass, wind, hydro, etc. • Biomass → farm animals → horsepower, food Later, people also did these conversions: • Coal → heat

Energy Transformation (Conversion): Definition and Examples
Energy transformation or energy conversion is the process of transforming energy from one form to another. According to the law of conservation of energy, energy can neither be created nor destroyed. In other words, energy does not appear out of anywhere and disappears into nothing. It transforms from one form into another.

Solar Thermal — Conversions
Solar thermal generates energy indirectly by harnessing radiant energy from the sun to heat fluid, either to generate heat, or electricity. To produce electricity, steam produced from heating the fluid is used to power generators.
