Passive And Active Solar Energy Technology

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.

Passive and active solar energy technology.

An interesting hybrid method is to use a solar panel to operate pumps or fans. Passive solar systems operate without reliance on external devices. Passive solar energy is a technique in which solar energy is used in a natural way. 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.

The future of active vs passive solar. From solar pool heating systems to solar water heating systems active solar energy is a cost effective way for homeowners to take advantage of solar energy this solar energy technology is called active because you are actively gathering and using energy from the sun for your solar home heating needs. Passive solar energy passive solar technology does not require the use of specialized mechanical devices or equipment to convert the sun s energy to power. Passive solar technologies use sunlight without active mechanical systems as contrasted to active solar such technologies convert sunlight into usable heat in water air and thermal mass cause air movement for ventilating or future use with little use of other energy sources a common example is a solarium on the equator side of a building.

Maybe a future president will one day put thermal solar panels or even some new solar technology we aren t aware of on the white house again just like jimmy carter did 40 years ago. Active solar thermal energy through small pumps and fans can have significantly higher solar saving fractions than passive solar energy technology due to improved heat transfer and transport. Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy. Again passive solar tracking would rely on the inherent thermo dynamic properties of the materials used in the system rather than an external.

Passive solar technologies offer significant savings especially when it comes to space heating. It also does not need power coming from an external conventional source. Passive energy systems use the sun s energy for heating and cooling purposes. Technology to harness the power of the sun can be either passive or active in design and either can be effective in making a home or business more energy efficient.

Passive solar systems passive solar panels depend heavily on the design construction and building of your home. While thermal solar is out of vogue right now as solar technology moves forward you never know what will happen.
