F24S

SOLAR HEAT COLLECTORS; SOLAR HEAT SYSTEMS (for producing mechanical power from solar energy F03G6/00)

Introduced: January 2018

Description

F24S covers solar thermal collectors and complete solar heating systems designed to capture and utilize solar energy for heating applications. This includes flat-plate collectors, evacuated tube collectors, concentrating solar systems, and integrated solar heating installations for residential, commercial, or industrial use. The classification encompasses both the collector components themselves and system-level technologies such as heat storage, circulation systems, and thermal control mechanisms. Adjacent photovoltaic technologies (F24J) and other renewable heating methods are classified separately.
