Solar energy is solar radiation or sunlight that’s given off by the sun. Alexandre Edmond Becquerel discovered the photovoltaic effect which is how electricity can be generated from sunlight, but the solar cell wasn 't invented until 1941 by Russell Ohl. which creates electricity or heat. Solar power cells convert solar radiation or sunlight into electricity, using the energy of photons to make an electric current within the solar panel. The electric current then flows out of the solar panel into an inverter that converts the DC power into an AC power, which is then used by the population. There are two types of these solar panels, there’s a passive and an active. Passive solar panels convert solar radiation into usable heat for air and water. These panels are best used for heating purposes such as a greenhouse’s, sunrooms or solariums. The other type of solar panel is active solar panels which are used to product heat and electricity using technology called solar photovoltaic. These solar panels are mostly used to furnish electricity to homes and buildings, while the larger models power for the entire community.
Solar energy is getting so big that the Department of Energy promised to fund seven million to emerge solar technology. The main reason solar energy is getting so big is because of the advantages of the use of solar energy. The main advantage of solar energy is that the power source is infinite unlike fossil fuels which are limited. Scientist currently predicts that in the next forty to fifty years fossils fuels will expire. Also solar energy is cleaner, rather than fossil fuels, solar energy doesn’t give off pollution and also is water efficient. Nuclear power plants and gas power plants use...

...nt is IVANPAH, in California which was operational 2013. It took 2.2 billion dollars to make and it took three years to makes. Some of the plants have reflectors and solar receivers such as IVANPAH which increases the cost of the plants, but increase the efficiency. To decrease the price of these cost some scientist suggest using different materials for solar cells, which lower the fabrication cost, but most solar cells designs require high purity to create which it’s the reason there so expensive.
The price of electricity isn’t as much of an issue, the price per kilowatt of solar power is 0.30, but the price is getting cheaper. The price is predicted to be at 0.10 cents per kilowatt in 2015 and will be possible be able to compete with the price of fossil fuels. In 2018 experts predict the cost of solar power drop below retail electricity rate in the United States.

The Energy Of Solar Energy Essays

- Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy, which is not such a bright idea since nonrenewable resources, such as oil, coal, and gas, are limited (Eia 1). Most significant uses of coal are in steel production, electricity, cement manufacturing, and as a liquid fuel. Solar energy is one of the least used energy sources we have access to in the world; it is also one our mother Earth is relying on to save the nonrenewable fuels, such as fossil fuels....   [tags: Sun, Solar energy, Photovoltaics, Energy]

Essay on Solar Power And Solar Energy

- The sun is a vital part of life on Earth. Plants need sunshine to survive and proceed with photosynthesis, the water cycle is powered by the heat the sun gives off, and walking outside on a sunny day can cause people to feel rejuvenated. In addition, the light that the sun gives off has the potential to become the predominant source of energy for society as it exists today. This is because solar power is a form of energy that can be harnessed in a variety of different ways, has the ability to provide for a diverse range of needs, is becoming more affordable at a rapid rate, and is completely renewable....   [tags: Sun, Solar energy, Fossil fuel, Solar power]

Essay on Science Research Project (Solar Energy)

- According to my research about solar energy I recommend that FPL develop more solar energy production facilities and assist individual homeowners in applying solar panels to their homes. My recommendation is based on many factors. One of the major factors for considering solar energy is that Florida is almost always sunny. There are about 8 hours of sunlight for a normal day and it seems logical to harness the sun’s energy for our needs. When storing solar energy it makes more sense to connect to a utility grid and sell the excess power to a utility company because the batteries that store solar energy are very expensive and large....   [tags: Solar Energy]

The Effect Of Solar Energy On The Environment Essay

- “In Table 1 basic criterion are collected to get a better overview of the main characteristics of each source. The overall status of solar energy is positive because of the high amount of energy available, variations of gained energy types and low impact on environment. Very important, in this case, is the establishment in small scale, in means of good possibilities to use this source for personal use. The price factor shows the average situation now, but it is variable with the tendency to decrease for most of the sources with the lapse of time....   [tags: Solar cell, Photovoltaics, Solar energy]

Future Of Solar Energy Technologies Essay

- Future of Solar Energy Solar energy technologies (SETs) supply energy with less environmental hazards than oil, natural gas or coal. SETs are often overlooked because of initial start-up costs and aesthetics. As technology progresses, the costs are projected to decrease, thus becoming more accessible for businesses and homeowners alike. Even in the states that are prone to prolonged overcast or cloudy weather, the use of solar energy is still viable because it will cut down on the need for pollution-excreting fossil fuel power plants....   [tags: Photovoltaics, Solar energy, Fossil fuel]

Disadvantages of Solar Energy Essay

- At the bottom of water is plant matter. That is what coal starts off as. It is covered in sediments and eventually goes through metamorphosis. After metamorphosis, it eventually becomes coal, which is one of the three most important resources on Earth. Another resource is solar energy, which is now being widely used in a variety of ways. Panels and sun light are what is used to collect this type of energy efficiently. The third type of energy resource is water. This type of energy can be conserved when a plan is implemented....   [tags: energy resource, environment, solar energy]

Solar Energy Essay

- Someday, our energy sources are going to run out. What will we do. What can we do. Our major source of energy now is fossil fuel. If that were to run out, there must be an alternate way to get energy. Because of this problem, there has been a lot of research going on. Through that research, alternate ways to get energy have been developed. They include wind energy, solar energy, nuclear energy, tidal energy and many more. In this paper I will focus on the aspects of solar energy. I will look at the history of solar energy, cover the advantages and disadvantages of solar energy and then finally I will talk about the concept of solar energy (how it works) and ways that solar energy can be use...   [tags: Energy Sources, Solar Power]

Essay on Solar Energy

- Solar Energy There is a bright future for solar power (no pun intended). On the average sunny day the sun shines approximately 1,000 watts of energy per square meter, enough energy to power all of our electricity needs and excess(“How”). This plethora of power and will be utilized in the future because we can't afford not to. It is predicted that in 100-500 years our fossil fuels will be depleted: this means that alternative sources of energy will be a necessity (Exxon). We consider solar power a renewable resource because it is conitinuosly supplied to us by the sun....   [tags: Renewable Energy, Solar Power, Environment]
