Reason to Lister: Natural resources will not. Solar Power: An Alternative Energy Source Since first discovered in the s, the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells, the methods of using solar power are becoming more efficient and cost-effective.

Solar technology is currently being used by homes and businesses, but is still too expensive and risky for many residents. Researchers are still making advances to solar.

Solar Energy in the United Arab Emirates Essay

The capacity of solar radiation a place receives depends on a variety of factors such as geographic location, time of day, season, and local weather. According to Knier n. Photo voltaic cells generate electricity directly using solar cells and concentrated. He invented the first photovoltaic cell. Since then his studies and works have been perfected on and continue to change the world in which we live for the better.

What is Solar Energy?

Photovoltaic cells have constantly been evolving ever since. In , Charles Fritts built the first solid state photovoltaic cell using materials such as gold and selenium. With further advances to. Solar energy is capable of providing a cleaner energy than most forms of energy generation, and solar energy is able to be generated economically.

Solar energy reduces the amount of harm to the environment from energy generation, by providing a cleaner alternative. Solar energy also provides jobs for construction and installation of solar powered technologies. The cost of installing solar panels can vary greatly, but its long term benefits outweigh the costs. Typically a solar panel system is.

Ever since , SolarCity was the leading company for solar energy in California and holds its place as the number one residential installer in for the United States and also a second place for solar installation for the country. It is a very simple technology which can cut short on the cost of energy consumption and make the earth a better place for us to live in. Also read: Biotechnology: pros and cons. As we can see, solar energy is really the future for us. Although it has few cons, but these can be overcome easily with the advancement in technology.

World should make efforts to use solar energy in more efficient way. It will decrease the environmental harm which is caused by other energy creation process like coal etc. Solar energy is the need of the hour. The glass provides electrical insulation. It is also good protection from weather and other damaging forces. When minimal energy is needed, such as that necessary to power a small appliance, a single PV solar panel is sufficient.

If the power will not be supplied to the power grid, the solar panel s is connected to a charge controller, and battery. If it is intended for on-grid use, the solar panel array will be connected to an electrical inverter. PV solar power is solar energy in the form of sunlight, which has been collected by a photovoltaic module, and converted into usable electricity.

Strengths And Weaknesses Of Eliminative Materialism Philosophy Essay

Conventional silicon solar panels convert about 14 to 17 percent of sunlight into usable electricity. Late in , however, a new solar cell was introduced. Solar panels that utilize the new cell can convert into electricity 22 percent of the sunlight they collect. Theoretically, the maximum that the cells of a solar panel can convert is said to be around 26 to 27 percent of incoming sunlight.

Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a certain part of the sunlight is absorbed by those silicon cells.

The electrons begin to flow, and this creates an electrical current. Metal contacts built into the top and bottom of the PV cells draw off that current and it is sent to the grid or battery.

Advantages and disadvantages of solar energy | My Essay Point

It is now usable electricity. The power grid sends it on its way, if you have used an on-grid connection. If you are using a battery, it is stored in the battery awaiting your need. PV solar power is being used increasingly with great success, and while it is true that cloud cover can affect it, the cloudy country of Germany leads the world in successful use of solar panels.
