It also does not need power coming from an external conventional source.
Active and passive solar energy pdf.
Passive solar systems include these features.
In contrast to active solar systems passive systems operate without the reliance on external devices.
A passive solar system does not involve mechanical devices or the use of conventional energy sources beyond that needed to regulate dampers and other controls if any.
How passive solar energy works.
Passive solar energy works by absorbing solar radiation and retaining heat through the use of thermal mass.
It is also helpful to understand specific savings in cost for buildings that use passive solar energy.
Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy.
This is a term that refers to any material that stores heat.
Passive solar energy does not require mechanical equipment and electronic devices to gather and distribute solar energy.
Examples of passive solar energy use include the following.
Thermal solar panels which are used to pre heat water for use in the home thereby lowering energy bills can also be a form of passive solar depending on the set up.
Remember passive solar simply means that the sun s heat or light isn t processed into something else.
