Solar energy part of our clean energy future. Solar Energy is the most abundant energy source on Earth. It can be captured and Used in many ways, and as a renewable energy source, is a significant
What is Solar Energy
Solar power can be harnessed and converted into usable energy using photovoltaics or solar thermal collectors. Although solar power only accounts for a small number of overall global energy usage, the decreasing cost of installing solar panels means that a growing number of people in more places can take advantage of solar power.
Solar is a clean, renewable energy source, and figures to play a significant role in the global energy future. Where does all this energy come from? Our sun, unlike any star in the galaxy, is similar to a large nuclear reactor.
Deep in the Sun’s core, nuclear fusion reactions produce massive amounts of energy which radiates outward from the Sun’s surface and into space in the form of heat and light. The sun does more than for our world than just provide light during the daytime – every particle of the sun (called a photon) that reaches Earth contains energy that fuels our world.
Solar power is the ultimate resource accountable for all our weather systems and energy resources in the world, and sufficient solar radiation strikes the surface of the planet every hour to fill our global energy demands for an entire year.
Harnessing The Power Of The Sun
There are many ways to use energy from sunlight. The two main ways to use power from sunlight are photovoltaics and solar thermal catch.
Photovoltaics are far more common for smaller-scale electricity projects (such as residential solar panel installations), and solar thermal capture is typically only used for electricity generation on massive scales in solar utility installations.
In addition to generating power, lower temperature variations of solar thermal projects may be used for cooling and heating. Solar is one of the fastest growing and cheapest sources of electricity in the world and will continue to spread quickly in the next few years.
With solar panel technology is improving every year, the financial advantages of solar enhance, adding to the ecological perks of deciding on a clean, renewable energy resource.
Solar panels convert solar power into usable electricity through a process called the photovoltaic effect. Incoming sunlight strikes a semiconductor material (typically silicon) and knocks electrons loose, setting them in motion and creating an electric current then can be captured using the wiring.
This current is called direct current (DC) power and have to be converted into alternating current (AC) power with a solar inverter. This conversion is necessary because the U.S. electrical grid works using AC electricity, as do many household electrical appliances.
A frequent method for property owners to benefit from solar power is using a photovoltaic (PV) solar system. Using a solar PV system, solar panels convert sunlight directly into electricity which can be used immediately, stored in a solar panel, or delivered to the electrical grid for a credit on your electric bill.
Solar power could be captured at many scales using photovoltaics, and installing solar panels is an intelligent way to save money on your electrical bill while reducing your reliance on nonrenewable fossil fuels.
Large companies and electric utilities may also benefit from photovoltaic solar power production by installing large solar arrays that can power business operations or provide energy to the electrical grid.
Solar Thermal Energy
A second way to use solar energy is to capture the heat from solar radiation directly and use that heat in a variety of ways. Solar power has a broader range of uses than a photovoltaic system, but using solar thermal energy for electricity generation at small scales is not as practical as using photovoltaics.
There are three general types of solar thermal energy used: low-temperature, used for heating and cooling; mid-temperature, used for heating water; and high-temperature, used for electrical power generation.
Low-temperature solar thermal systems involve heating and cooling air as a means of climate control. An example of this type of solar energy usage is in passive building design. In properties built for passive solar energy use, the sun’s rays are allowed into a living space to heat an area and blocked when the area needs to be cooled.
Mid-temperature solar systems include solar hot water heating systems. In a solar hot water setup, heat from the sun is captured by collectors on your rooftop. This heat is then transferred to the water running through your home’s piping so you don’t have to rely on traditional water heating methods, such as water heaters powered with oil or gas.
High-temperature solar thermal systems are used for generating electricity on a larger scale. In a solar thermal electricity plant, mirrors focus the sun’s rays on tubes containing a liquid that can hold heat energy well. This heated fluid can then be used to turn water into steam, which then can turn a turbine and generate electricity. This type of technology is often referred to as concentrated solar power.
