Solar heat systems are arrangements that use renewable solar energy from the sun and convert it into the form of heat and electricity.
Solar collectors are present in the active system but are absent in the passive system.
What are the two types of solar heating systems?
The active system of solar heating uses the solar energy to heat and directly passes the rest to the storage. They use the solar collector to collect solar energy by absorbing the radiation from the sun.
The passive system includes installations and designs that do not collect the heat and utilize the heat directly for use. The system lacks mechanical parts.
Therefore, option D is correct.
