Active And Passive Solar Energy

Passive solar systems include these features.

Active and passive solar energy.

In contrast to active solar systems passive systems operate without the reliance on external devices. It also does not need power coming from an external conventional source. Unfortunately passive solar energy relies more on the weather. Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy.

Rather such as in greenhouses solariums and sunrooms solar energy captures sunbeams through glass windows that absorb and retain heat. Active solar energy systems include the use of photovoltaic panels and solar thermal collectors to harness the 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. 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.

Passive solar energy systems include orienting a building to the sun. Unlike passive solar heating active solar heating uses mechanical and electrical equipment to enhance the conversion of solar energy to heat and electric power. Passive solar energy on the other hand is typically cheaper than active solar energy. Remember passive solar simply means that the sun s heat or light isn t processed into something else.

Passive solar systems passive solar panels depend heavily on the design construction and building of your home. Active solar energy systems use the same principles as passive systems except that they use a fluid such as water to absorb the heat. A solar collector is a device used. Passive solar energy does not require mechanical equipment and electronic devices to gather and distribute solar energy.

You may also have the potential of overheating a building if you re located in a warm climate because you can t regulate the temperature as well. 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. 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.

They use passive collectors to convert rays into the sunlight.
