The top or sunny side has a glass or plastic cover to let the solar energy in.
Active solar energy examples.
The inside space is a black absorbing material to maximize the absorption of the solar energy.
Active solar heating systems use solar energy to heat a fluid either liquid or air and then transfer the solar heat directly to the interior space or to a storage system for later use.
Again passive solar tracking would rely on the inherent thermo dynamic properties of the materials used in the system rather than an external.
Solar trackers used to orient solar arrays may be driven by either passive or active technology and can have a significant gain in energy yield over the course of a year when compared to a fixed array.
On the other hand by means of thermal solar panels we transform radiation into heat energy.
Flat plate collectors are usually placed on the roof or ground in the sunlight.
If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat.
Passive solar energy is the technique that allows you to harness solar energy directly without having to process it.
These equipments can be fans water pumps etc.
This use of solar energy is often called passive solar.
Active solar heating systems operate as follows.
Passive and active while there are many different ways to use the sun rsquo s heat how that heat is used and transferred determines whether the system is active or passive.
