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.
Active solar energy examples.
The inside space is a black absorbing material to maximize the absorption of the solar energy.
Again passive solar tracking would rely on the inherent thermo dynamic properties of the materials used in the system rather than an external.
The top or sunny side has a glass or plastic cover to let the solar energy in.
These equipments can be fans water pumps etc.
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.
Concerning active solar energy photovoltaic panels we transform sunlight into electrical energy.
Passive solar energy is the technique that allows you to harness solar energy directly without having to process it.
Active solar heating systems operate as follows.
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.
Humans can capture solar energy directly from the sun through passive and active solar energy systems ancient people used passive solar energy systems by building their houses out of stone or clay which absorbed the sun s heat during the day and stayed warm after dark providing heat throughout the night.
Active solar energy classifies technologies related to the use of solar energy that use mechanical or electrical equipment to improve performance or to process the energy obtained by converting it into electrical or mechanical energy.
