Active And Passive Solar Energy

If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat.

Active and passive solar energy.

A solar collector is a device used. Solar energy system are broadly characterized as either passive solar or active solar depending on the way they capture convert and distribute solar energy. Unfortunately passive solar energy relies more on the weather. Remember passive solar simply means that the sun s heat or light isn t processed into something else.

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. In contrast to active solar systems passive systems operate without the reliance on external devices. Rather such as in greenhouses solariums and sunrooms solar energy captures sunbeams through glass windows that absorb and retain heat. Passive solar energy does not require mechanical equipment and electronic devices to gather and distribute solar energy.

It also does not need power coming from an external conventional source. 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 energy systems include orienting a building to the sun. 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. They use passive collectors to convert rays into the sunlight. Passive solar systems operate without reliance on external devices. 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 solar systems include these features. Passive solar energy on the other hand is typically cheaper than active solar energy. Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy. Passive solar systems passive solar panels depend heavily on the design construction and building of your home.

Unlike passive solar heating active solar heating uses mechanical and electrical equipment to enhance the conversion of solar energy to heat and electric power.
