Medium temperature solar thermal applications have received remarkable interest in the recent years in both residential and industrial sectors. Solar concentrating systems can serve properly such applications with a temperature range of 80–250°C, taking advantage of their sun light focusing characteristic and high thermal and optical performance.
Almost all industrial process heat demand requires heat in temperature ranges that can be provided by a solar thermal system. Typical applications and the most promising sectors of industry suitable for solar thermal systems for industrial applications are listed in Table 1. Most applications are in the low- to medium-temperature ranges.
Other common and successful solar thermal applications include solar cookers, solar distillation and desalination systems, district heating, swimming pools heating, solar ponds, solar chimneys and high-temperature solar thermal power plants for electricity generation.
For medium temperature process heat applications, some advanced FPC designs with ultra-high vacuums are available to provide temperatures up to 200°C. However, the main technology used for medium temperature heat are solar concentrator technologies.
Prime ap-plication areas for solar thermal systems are in the food, beverage, transport equipment, textile, machinery, and pulp and paper industries, where roughly 60% of the heating needs can be met by temperatures below 250°C (PO-SHIP, 2001).
Integration of solar heat systems into industrial applications requires storage and control strategies to handle the non-continuous supply of solar energy (Atkins, et al., 2010; Schramm and Adam, 2014).
