Unglazed Solar Collector
The unglazed solar collectors (for 35–40°C) are typically used for low-temperature heating applications (e.g., swimming pool heating) and therefore, not recommended for industrial applications. A liquid flat plate collector can be used for temperature applications up to about 80°C and an evacuated tube collector can reach up to about 120°C.
