Solar energy is defined as energy obtained from the sun's radiation. The two main forms of solar energy include active solar energy and passive solar energy.Know More
Active solar energy involves equipment or an action to convert solar energy into a useful form. One example of active solar energy is the use of solar cells to convert energy from the sun into electrical energy that can be used in the home.
Passive solar energy does not require any specific action or equipment. An example of passive solar energy is strategically placing windows in a home to allow sunlight to enter and provide heat.Learn more in Environmental Science
Photovoltaic solar power is produced when photons contained in sunlight strike silicon or another conductive surface in the solar panel. The photons excite the silicon molecules, causing them to move around, which then generates a small current of electricity.Full Answer >
Some examples of solar energy applications include solar powered window blinds, bulbs, refrigerators, radios, calculators, greenhouses, swimming pools and air conditioning systems. These are just a few of the applications that use this form of energy.Full Answer >
Some of the benefits of solar energy include the fact that it is entirely renewable and unlimited, produces low emissions, is economical and provides jobs. Like all forms of energy, it has benefits and drawbacks.Full Answer >
Water-holding capacity is defined as the water retained between field capacity and wilting point. Field capacity is the saturated state of water in the soil that can drain freely due to the force of gravity. Wilting point is the soil water level after its absorption by a plant.Full Answer >
