A direct solar collector directly absorbs and converts sunlight into usable heat energy, while an indirect solar collector uses a heat transfer fluid to transfer heat from the collector to a separate system or storage medium.
A direct solar collector absorbs and converts sunlight directly into heat energy, while an indirect solar collector uses a fluid or other medium to transfer the captured energy to another location for conversion or storage.
A direct solar collector absorbs solar radiation and converts it into heat energy directly, while an indirect solar collector uses a heat transfer fluid to absorb solar radiation and then transfers that heat to another medium for utilization.
