The Advantages And Disadvantages Of A Solar Power Fan
The actual term solar power is used to describe not only one issue, but rather a number of methods that involve the harnessing of energy from the light of the sun. There are many different and incredibly resourceful matters that solar power can be and is used for, and the actual subject of solar power is becoming one of quickly increasing popularity. A solar power fan is one of the available uses for solar power, however, as with anything else, a solar power fan does have both its advantages and disadvantages.
What Is A Solar Power Fan?
A solar power fan is a fan for those home owners who do not want to use a fan that is run by the more conventional method of electricity. A solar power fan is, instead, powered directly by sunlight, and the fan will stop at sunset when there is no longer enough sunlight available to power the motor any further. There are both advantages and disadvantages to a solar power fan, and both halves which must be taken fully and thoroughly into consideration before can truly shape an opinion on a solar power fan.
What Are The Advantages?
There are certain advantages to this type of solar powered fan, such as the fact that you do not have to power the fan at all with your own electricity. As well, you do not have to run any electrical wiring to the fan. This can save a lot of time and money as an end result, and is considered as an extremely positive set of factors to the environmentally concerned person.
What Are The Disadvantages?
As with anything, however, there are also disadvantages that come with the solar powered fan, such as the fact that the fan must run on solar power. Thus, the motor is simply not as powerful and it also is much smaller. The fan also covers a lot less space than a regular fan, so you might find that you will have to supply yourself with two of these fans, when you would only need one of the regular forms. As well, the actual cost of a solar powered fan is higher than that of an electrical fan, primarily due to the fact that there is the cost of the solar cell which is additional.
Obviously, you must weigh the advantages and disadvantages out, and the final decision is truly dependent upon your own personal preference.
The Advantages And Disadvantages Of Solar Power Cars
What Are Solar Powered Cars?
Solar powered cars are electric vehicles which are powered by solar energy that is obtained from solar panels on the surface of the car. Basically, photovoltaic cells then convert the sun’s energy directly into electrical energy. Solar powered cars are can operate for limited distances without the sun, but they are still not considered as a practical form of transportation.
Solar powered cars were first built by universities and manufacturers, and development continues on solar cell design and car power supply requirements such as heater or air-conditioning fans.
The solar array on solar powered cars consists of hundreds of photovoltaic cells converting sunlight into electricity. Cars, unlike many other objects that use solar energy, can use a variety of solar cell technologies, which most often involves polycrystalline silicon, monocrystalline silicon, and gallium arsenide. Solar cars usually have incredibly distinctive shapes, as designers aim to minimize drag, maximize the exposure to the sun, minimize weight and still make the vehicles as safe as possible.
The Advantages And Disadvantages
There are both advantages and disadvantages to solar cars, and all of these should be taken carefully and thoughtfully into consideration. Some of the advantages include, for one, that of safety and convenience, for instance there are batteries available on most solar cars which store electrical energy that is to be used later by the electric motor when the demand for electric power exceeds that of the output of the onboard generating device.
There is also the advantage involving efficiency, which relates to the fact that all solar cars are able to produce their full rated power at any speed, unlike that of regular automobiles. Another prime advantage of solar cars is that they are positive in regards to the economy. This is because an electric motor and an electric generator are the same device, basically, and electrical current is fed into such a device, causing it to act as a motor and, thus, creates mechanical power.
There are certain disadvantages, too, such as, most of the solar cars available do not have the power or speed of many of the regularly available cars and vehicles and, as well, the battery on the solar car may have to be used far too frequently depending on the weather, for instance if it is dark out for several days, you will have to rely on the battery of the car in order to make it work. This can seem as a hassle to many people, which is a large explanation towards why solar cars still aren’t that popular today.
The Basic And Most Primary Advantages And Disadvantages Of Solar Power
What Is Solar Power?
Solar power is an incredibly and dramatically important issue, and there are many important issues in regards to the matter of solar power. Solar power technologies use the sun’s energy and light to provide heat, light, hot water, electricity, and even cooling for such things as homes, businesses and industries. There are several primary solar technologies that are used, which include that of: photovoltaics, passive solar heating, concentrating solar power, and solar hot water and space heating and cooling.
Photovoltaics are solar cells which are used to directly convert sunlight into electricity. These solar power cells are made of semi conducting materials, and crystalline silicon is the leading commercial material for photovoltaic cells, which can be used in itself in many forms, including that of: single-crystalline or monocrystalline silicon, multicrystalline or polycrystalline silicon, ribbon and sheet silicon, and thin-layer silicon.
Passive solar power heating involves that of buildings which are designed for passive solar and daylighting incorporate design features such as that of south-facing windows and building materials that absorb and slowly release the sun’s heat. In passive solar heating, there are no mechanical means at all used, and passive solar designs can also include that of neutral ventilations for cooling.
The concentrating of solar power involves that of technologies which use reflective materials such as mirrors in order to concentrate the sun’s energy this then concentrated form of energy is converted into electricity. Solar hot water heaters on the other hand, use the sun to either heat water or a heat-transfer fluid in collectors. A typical solar hot water and space heating and cooling system will reduce the need for conventional water heating by about two-thirds, which is obviously considered as being quite dramatic.
Solar power, besides providing heat and light, is also what causes the wind that we feel on Earth. This is because winds are created when various layers of that atmosphere absorb different amount of heat and therefore expand differently, thus creating regions of lower and higher pressure, which results in masses of air that circulate both at ground level as well as that of higher altitudes. Solar power is also responsible for fossil fuels such as that of petroleum and coal, as these substances are the result of large masses of decayed plant matter, which during their own lifetime, had absorbed solar energy.
