Learn The Advantages And Disadvantages Of Solar Energy As A Source Of Alternative Power
December 26, 2009 by Go Green Tips · Leave a Comment
Solar power is gaining popularity throughout the world as a free source of energy. Unlike other energy sources, solar energy is energy from the sun which means it is free. This free energy is converted into usable power using solar panels. These solar panels can either be homemade or purchased from solar panel dealers. Solar generated power is gaining popularity not only because it is free, but more so because it is renewable. As long as there is enough sunlight, there is free power.
Besides being renewable, solar generated power is clean energy. In today’s world where global warming is becoming a challenge, solar power is one of the easy solutions. Since there are no waste products emitted from solar panels, solar energy is considered the most environmental friendly source of power in the residential homes.
Solar power is considerably cheap as a source of energy at home. The only major expenditure is the initial installation cost. However this can be minimized by building a solar power generator at home using Do-It-Yourself (DIY) guide. There are several easy to follow DIY manualsreadily available online, the only advise is to find the most reliable one. Once the original cost is covered, there is hardly any other maintenance expense needed.
Another solar energy advantage over other sources of energy is ease of access. In other words, solar energy can be harvested anywhere in the world as long as there is sunlight. This makes it possible to be used in the most remote parts of the world where there is no electricity. Since solar panels can be built or installed within few days, one can use solar generated power on both permanent and temporary residential buildings and structures. It can also be scaled up to meet the changing needs of a home.
In areas where there is sufficient sunlight, it is possible to build large enough system to generate power in excess of what is necessary to run a home. In such a case, the surplus can be sold to the power companies or other residents hence becoming a source of income.
Despite the solar energy advantages above, there are some disadvantages as well. Since solar generated energy relies on the energy from the sun, it may not be the best energy source choice for areas with insufficient sunlight throughout the year e.g. extreme North or south of the equator. In such situation other renewable energy options such as wind and magnetic power generators may be ideal.
The primary cost of installation for large home buildings may be high in the short run especially for low income people. In such case, it may be better to build solar panels at home one by one until the energy needs for the home have been met. Another option is to look for funding from the bank or government grants for home improvements.

Why You Should Choose To Use Solar Power

Life on earth is fueled by the light and heat from the sun. Approximately, 3850 Zettajoules (ZJ) per year is the total amount of solar energy available to the earth. The suns energy travels to the earth by way of electromagnetic radiation like radio waves but the frequency range is different. Some of this energy is absorbed as it comes thru the atmosphere. Heat and light are the primary forms of solar energy.
Solar energy has many advantages over conventional energy. The energy from the sun is free the only expense is from recovering the energy. The cost of recovering the suns energy is recovered faster than with conventional energy. The recovering units don’t have to be connected to natural gas or power grids, they stand alone. The supply of solar energy is limitless. It has no emission gases to harm the earth’s atmosphere.
There are several ways to recover solar energy:
Focusing collectors: This has a movable mirror, known as heliostats, is pointed to the sun and can provide a temperature around 4000 degrees C. This degree temperature is used for a solar furnace in industries and research. These solar furnaces don’t contaminate our environment. The heliostats can focus the energy to a boiler that turns water into steam. To generate solar electricity, focusing collectors can be used.
Flat plate collectors: These collectors can be used in schools and homes to provide heat using water that is heated in pipes. They cannot provide as much heat as the focusing collectors because they are smaller.
Solar distillation: Solar distillation is about the same as flat plate collectors but provides distilled water instead of heat. Sea water is put in tanks or ditches on the roof of a house and the heat from the sun heats and evaporates the water and turns the water vapor into liquid water that is distilled.
Solar electricity: By using focusing collectors and Photovoltaic cells, made of thin pieces of semiconductors, convert radiation from the sun into electricity.
Solar energy would not be affected by the supply and demand of fuel for it is free and it doesn’t polute the atmosphere. It is natural and pure. It would provide us with better health.
There are several ways that we can work together in order to get the best of natural and renewable resources. Using solar power is not only helpful but it is inspiring to others. The expenses to using the solar energy are less than the cost of using other resources for heat, including electricity and gas. When you use electricity and gas you may have a low cost up front but in the end you end up paying for it from now on. With solar power you may have an initial investment to turning your home into solar power but after that you have no reason to pay for it any further, unless you use electric or gas for a back up heating source. Solar power was available yesterday, it’s available today and hopefully it will be available for us in the future.

What Is Solar Energy

In order to know where to find solar energy you must first know what solar energy is. Solar energy is energy from the sun. When the sun is shining solar energy is being produced as it sends the heat radiating to the earth. You can find solar energy anywhere or anything that the sun can shine on. There is a way that you can save the sunlight in order to provide heat during the cold, which is what millions of people have done throughout the years. It started thousands of years ago when people where able to use a thick lens or magnifying glass on an object that would attract the sun rays on that particular object and could get so hot it would catch fire. This gave a new prospective on how strong the heat from the sun really was.
The problem with capturing the suns heat is the fact that when it reaches the earths surface it does not go to one particular spot. It is spread evenly over the earth where the sunlight is able to reach. When this happens you may find it difficult to heat something using only the sunlight. Although the area or object may be hot if left in the sun too long it will not reach the full heating potential of the sun’s light.
In order to use the heat efficiently to heat a room after the sun goes down or when the sun is unable to shine because of clouds you will need to use a source that will attract the heat to one particular area. This source is called a solar collector. The solar collector attracts a lot of sunlight to one particular area allowing the sun to pass through the source and into the space. The objects in the space absorb and hold the heat from the sunlight and trapping it so it will not get back out with the help of the source. Glass is a great solar collector because it allows the sun to pass through it and into the space but the heat from the sun can rarely escape leaving the space under the glass to become warm or hot from the heat. The objects in the space help to hold the heat as it comes in so that the space will stay warmer longer. This allows the area to be heated using solar power.
Because glass is a natural solar collector it makes it great to put into a greenhouse or a sun room. The glass attracts the sunlight and traps the heat inside so that they temperature in the greenhouse or sun room remain warm even at night when the temperature outside may be cold.
Solar energy can be found anywhere the sun shines but in order to fill the heat you must have direct sunlight for an extended period of time. If you just use the morning sun to heat your home your house may not stay warm through the night.
