Solar Power Batteries

Any discussion regarding the effectiveness of solar power and its efficiency should first of all be qualified by the fact that we're talking here about a technology that is in its relative infancy and is improving all the time.

That having been said, it's fair to say that, while massive improvements have been made in the overall efficiency of solar panels, there's still a long way to go.

Let's take a look at how solar panels work and get some background as to why this is and what can be done to improve solar panel efficiency.

The Secret's In The Cell

The solar cell is the basic building block of a solar panel and is where all the action takes place as far as the conversion of sunlight into electricity is concerned. A cell consists of a negative and a positive silicon wafer, which work together in reaction to the sunlight striking them to cause electrons to literally jump out of the wafers to create a DC (Direct Current) electrical circuit. This is known as the photovoltaic (PV) effect.

Several cells (normally 30-40) are wired together to create a panel and the electricity generated by each cell is accumulated to supply enough power from a panel to power a small electronic device or charge a battery, but not enough to supply the power needed to run a household or business. To do that, a number of solar panels are wired together to supply the kind of electricity needed to run household appliances, etc.

What's Meant By Solar Cell Efficiency?

When we talk about the efficiency of solar cells and, consequently, solar panels, we're actually referring to the amount of sunlight that the cell converts to usable electricity. The efficiency of cells has come a long way since the early days of PV when cells were 1-2% efficient (i.e. about 1-2% of sunlight was converted into electrical energy). Nowadays, cells are between 7% and 17% efficient, which is a massive improvement, but that still means that 83-93% of the available sunlight remains unused.

The efficiency of a solar cell is dependent on several variables, including cell type and temperature. The higher the temperature of a cell is, the lower its output and, as a result, the lower its efficiency. The type of cell used will also affect its efficiency, with monocrystalline being the most efficient (14-17%), polycrystalline next most efficient (13-15%) and amorphous (or thin film) the least efficient (5-7%), with the relative cost of each directly proportional to its efficiency, i.e. monocrystalline being the most expensive while amorphous is the least expensive.

How About Giving Me 100% Efficiency?

Unfortunately, despite advances being made in production processes, and work being done to improve cell efficiency, even at its best the maximum efficiency level that can be achieved for crystal silicon is still only around 28%. This is due to certain physical limits caused by the materials themselves, in addition to certain loss mechanisms such as the fact that photons having too little energy end up not being absorbed, and excess energy from the photons is converted into heat.

So, even with the best will in the world, 100% efficiency is simply not achievable. Certain techniques are being used to improve cell efficiency, such as reducing reflection loss through surface structuring, or stacked (or tandem) cells, or concentrator cells, so there's plenty of room for optimism for the future efficiency of cells.

But, even with the restrictions on the potential efficiency of solar cells, the fact that we're able to produce usable electricity from such an unlimited source of energy as the sun is nothing less than miraculous in and of itself. Add to that the fact that this is clean, renewable energy with no carbon emissions or harmful effects that can reduce and potentially help eliminate our dependence on dangerous fossil fuels and it's clear that solar is a wonderful and effective technology whose time has come.

How Much Do Solar Panels Cost

In general, solar energy can be described as the energy that is received from the sunlight and converted by a mechanical source for home use. It's cheaper and reliable for operations since the sun is readily available. On the other hand, solar panels are the mechanically built materials whose main purpose is to convert solar energy to electrical energy. They are built from an element called silicon. It is the core duty of the silicon element to covert the solar energy to electricity. The solar power can either be directly or indirectly gotten from the sunlight. When it's cloudy the intensity of the solar power delivered perfectly, the photovoltaic solar materials deliver sun rays into electricity and the solar thermal receiver changes the solar power into heat solvents, such as oil and water. This type of power is used in, iPod chargers, charge batteries water heaters, cell phone chargers and spacecrafts.

How do solar panels work? They practically work on the photovoltaic invention. Its name is derived from the technology used, which is also known as PV, which is made from silicon element. They are basically semiconductors made from sand built into large computer chips. When sun rays falls on the PV materials, the PN junction in it with its metal conductor helps produce electricity. At this juncture, the PN junction is the positive and negative charges that assist to produce electric current. Solar energy is available in different systems, grid connection, inverters and power storage. In a different system, the PV takes up large space up the roof to produce more energy. It can also be built on land space and produce up to 5-9 Megawatts per hour. They can also be useful in street lighting.

How are solar panels made? They are basically made from three-dimensional points; the crystalline silicon production, the crystalline silicon panels and the amorphous silicon panels. This stand of the solar-energy production is what is used in the present. In the crystalline silicon production, for example, when the silicon element is melted and cut it is named the poly crystalline silicon. In its other mode when it is built and cut, it becomes mono-crystalline silicon. In both cases, they are about; a hundred percentage pure silicon. In the second case of the crystalline silicon panels, they are normally broken into pieces and then sliced, finally being polished with doping materials. This changes the state of electric charge inside them to cells. The amorphous silicon panels are made from silicon alloys combined with multilayer cells for energy production. This combination explains how the solar power is made.

What are latest technologies of solar panels? The newest technology of solar energy has emerged in a wide range of things. This starts with the green power alternatives which is common for home use. The other aspect of it is the Power cooling and heating systems in homes. The high-technology appliance and periodic lighting at home is the other good examples of solar-energy development. New personal computers development for smart homes is also left out of the latest ideas of the solar power.

The topic of global warming is getting wide acceptance with more and more countries making the attempt to delay the insidious effects of this phenomenon. Today's scientists and conservationists are proposing choices for people that can be employed in their everyday life. Using solar power install or the power of the suns heat is one such endeavor. Solar energy is considered to be one of the most compelling forms of all energies on earth. It is derived from the sun, which has been producing energy for billions of years. Solar energy reaches the earth in the form of solar radiation and is changed directly or indirectly into various forms of energy like electricity and heat.

In spite of it being one of the essential sources of energy, solar energy has some drawbacks. They are:
1. The irregular and flexible manner of its reaching the earths surface
2. There is a need for a large area to collect it.

Some of the advantages of using solar power kits or energy are:
* Solar energy can be used for multiple purposes from heating water for use in homes to drying farming products and even generating electrical energy.
* Solar power is an inexhaustible resource, and it will take another billion years for the sun to disintegrate if ever it does. As a result, solar power kits will be able to provide us with enough power to meet day-to-day demand like electricity for homes, cooking etc and can be applied for commercial applications as well.
* One of the strongest advantages are that solar power is non-polluting, an environmental dream. As likened to any other energy resource such as oil or coal, solar power will not give off greenhouse gases into the air and therefore, is considered environmentally friendly.
* Solar power is for free. As equated to oil or coal, which you have to buy, using solar power kits will cost you much less or almost zero in the long run.We are quite aware of the ability of oil prices to fluctuate wildly but by being able to switch to solar power install this may put a brake on such moves. Initially, you might have to invest a little on the solar power kits. The upkeep of solar cells or panels is zero. Apart from this, the life of the solar power kits is much longer and usually panels come with lifetime warranty (20 to 25 years). You can use solar cells to heat water or to even power a car. The solar cells can convert sunlight into electricity and are often known as photo-voltaic cells.

In today's political and environmental climate things are extraordinary and the situation at hand with global warming can be best be described as grim. You can use solar power kits for various functions. Some of the uses of solar energy by organizations and individuals are as follows:
1. Companies are trying to apply photo-voltaics cells in electric utilities. Photovoltaic is a process through which solar energy can be converted into electricity directly.
2. Electricity can also be created directly from steam generators using solar thermal collectors that can heat working fluid.
3. There are many companies globally who have begun to implement Solar PV modules, which can easily be fitted on to existing roofs. Solar power kits can be linked to a buildings grid supply for yielding electricity, which can be utilized by all on the premises.

Photovoltaic Energy
Photovoltaic energy can convert sunlight into electricity by using photovoltaic (PVs) cells. These cells are usually known as solar cells. Photovoltaic cells are non-mechanical devices that are made primarily from silicon alloys. Sunlight is essentially composed of millions of extraordinary particles of solar energy also known as photons. Each photon contains a different degree of energy that corresponds to unique wavelengths within the solar spectrum. When a photon strikes a photovoltaic cell, they will either get absorbed, reflected, or pass right through. The photons which get absorbed can provide enough energy to generate electricity. When the required amount of energy gets absorbed by a semiconductor, then the electrons get dislodged from their material atoms. Photovoltaic cells are being increasingly employed in driving solar powered products.

Very simply put, 'Solar energy' is energy that is derived from the sun. Our sun is an easy source of energy; it gives off heat and light. The sun is a plentiful and inexhaustible reservoir of power. Therefore, it should be our aim to exploit this FREE resource for the worlds benefit and the improvement of our environment.

Building your own solar panels has never been easier. With new building techniques, making your own power is now a reality. Today we have better quality solar cells that can be purchased at reasonable prices to keep your building cost to a minimum. If you are wondering what it takes to build your own solar panels, then look at the list I have compiled for you. Here are the items you will need to make your own solar panels.

  • Solar cells-You will need at least 36 solar cells to start with. I purchase my cells from a company in California called Everbrite©. They have reasonable prices, plus when you order your cells you will receive extra cells because at first you will break one or two. You can order your solar cells in kits that include everything you need to get started.

  • Aluminum frame-I like to beef up my solar panel by purchasing 1/8" aluminum angle in at least 1" dimension, so that they will last for thirty years or more. The frame is to be the strongest part of your panel, so no skimping here.

  • Tempered glass-One thing that I learned about building solar panels, tempered glass is the best for making a system that will last and withstand all types of weather from hail storms, heat, and cold. I recommend 1/4" for strength and durability. Another good point to make here is that all your soldering can be done on this tempered glass which makes an excellent heat sink.

  • Encapsulate liquid-The best way to mount your finished solar cells to the glass is by using a special epoxy designed for manufacturing of solar panels. I used encapsulate from Dow© chemical called Sylgard, which comes in two parts, an A and B which when mixed will bond your cells to the glass, completely covering them from the elements. It is important to let stand for at least four days to cure.

  • Soldering tools-What I have found is that a soldering iron of 40 watts works best for soldering your tab and buss wires to your cells. It is good to have extra soldering tips available, because you will be replacing them at one point during your soldering process.

  • Hardware-You will need miscellaneous hardware such as 1/4" machine screws, 1/4" nuts, 1/4" lock washers, small angle brackets to join your corners of the aluminum frame together, and angle brackets to hold your glass in place.

Anyone can build their own solar panels for home with the proper instruction and training. Visit Earth Power Energy Systems to see other tips about building your own renewable energy systems.
