Active Solar Energy Examples

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.

Active solar energy examples.

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. These equipments can be fans water pumps etc. Concerning active solar energy photovoltaic panels we transform sunlight into electrical energy. 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.

If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat. 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. Flat plate collectors are usually placed on the roof or ground in the sunlight. 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. 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. Again passive solar tracking would rely on the inherent thermo dynamic properties of the materials used in the system rather than an external. This use of solar energy is often called passive solar.
