Passive And Active 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.

Passive and active solar energy. Passive solar systems operate without reliance on external devices. If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat. It also does not need power coming from an external conventional source. They can be huge large scale monstrosities that create electricity as well.

Passive solar systems passive solar panels depend heavily on the design construction and building of your home. Well this term refers to the direct use of solar energy for heating purposes. If you use the sun s heat to warm a water tank that would be passive solar. Passive energy systems use the sun s energy for heating and cooling purposes.

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. A solar collector positioned on the roofs of buildings heats the fluid and then pumps it through a system of pipes to heat the whole building. This can also include electronic controls and other systems commonly found on active solar technologies. They use passive collectors to convert rays into the sunlight.

Unlike passive solar heating active solar heating uses mechanical and electrical equipment to enhance the conversion of solar energy to heat and electric power. Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy. Active solar energy systems use the same principles as passive systems except that they use a fluid such as water to absorb the heat. Passive solar energy does not require mechanical equipment and electronic devices to gather and distribute solar energy.

It is different from active solar energy in that passive solar doesn t involve the use of any mechanical or moving parts. How passive solar energy works. Passive thermal solar just uses water and sunlight. Active thermal solar isn t limited to small rooftop systems.

If you were to pump that water through your walls to heat your home that would be active solar heating. Active thermal solar uses pumps antifreeze and a heat exchanger and is generally a lot more complicated. A solar collector is a device used.
