Compare And Contrast Passive And Active Solar Energy

In comparison to active solar systems passive systems need much less costs for maintenance and operating certainly under the conditions of their constant optimization for better performance.

Compare and contrast passive and active solar energy.

Active solar heating is often used as a retorfit into existing buildings. Passive energy systems use the sun s energy for heating and cooling purposes. The active part is pumps and fans that direct and concentrate the heat in a thermal mass where it can be actively accessed and distributed. Passive solar systems operate without reliance on external devices.

All over the country people are installing solar panels on their roofs to produce their own electricity and save some cash. The passive solar energy system works best for heating and cooling systems especially with small homes. They use passive collectors to convert rays into the sunlight. Passive solar systems include these features.

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. Energy conservation reduces the needed size of any renewable or conventional energy system and greatly enhances the economics so it must be performed first baker 2003. 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. 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. 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. The difference between active vs passive solar can get confusing.

Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy. Passive solar energy unlike its counterpart requires no external devices to collect or store solar heat. It relies entirely on itself and thermodynamics to collect solar heat and turn it into power.
