Home Sweet Solar Home – Making Homes Better With Solar Technology

Executive Summary about Solar Home by Anne Clarke

By now many people know it is possible to generate energy without the use of dwindling traditional resources. This stimulated atmospheric cycle is the product of a solar biosphere that remains in constant, gradual motion. You can draw energy directly from the sunlight, you can save money on energy costs, and you can be a big part of the effort to protect our planet. Remember, though, solar panels are not the only type of solar technology available that can harvest a decent alternative to electricity from the sun. There are wind turbines, solar panels, biospheres, and many other innovative solar power mechanisms that have made headway in an extreme scientific objective to help protect the earth. Despite what many people might believe, there are solar solutions available as alternative energy sources that virtually anyone can choose over electrical energy. Soon construction companies for homes, office buildings, apartment complexes, and more will adopt new methods of design that will dovetail more easily with solar technology.

What Is So Fascinating About Solar Pump

Solar-powered water pumps are an effective alternative to conventional gas or electric pumps. Modern pumps are powered by solar energy effectively in the world, including India, where they are often used for irrigation and drinking water.

The main advantage of solar pumps is that they work for free. A solar array connected to the pumping mechanism gains all the required power from simple sunshine. This also means that the system independently. There is no need for complicated wiring for the electricity and outside fuel is not needed.

The amount of pollution caused by the use of conventional pump has also completely eliminated. This is a big advantage, especially when used for irrigation on the farms where pollution can possible on site damage. Keeping the fossil fuels from the equation for the pumping of water will reduce potential contamination. In addition, the use of solar energy offers many benefits for agriculture, the farmers, for example, a solar pump used in an area of low-lying, which often flooded or to move the water used to feed animals and plants.

For any system of water pump, both large and small, the installation of solar systems is one of the easiest and most profitable. No long procedures for determining the wiring of the solar panels, and there is no need for extra fuel. Many of these systems, also the digital monitoring and control instruments adding for convenience.

Worldwide, the solar energy is one of the best ways of powering pump instrument. Simple installation, low maintenance, and reducing pollution are just some of the many benefits.

Solar Cell

November 24, 2009 By: Admin Category: Solar Cells

What Does Solar Cell Mean?

You may have seen a calculator that has a solar cell? calculator that does not need batteries, and in some cases do not even have the off button. As long as you have enough light, so the calculator can be on at any time and forever. You may have seen larger solar panels, such as in housing or traffic lights, haven’t you? In this article I will review how solar cell work so it can deliver the energy and drive an electronic device.

Today the demand for electricity has become a major requirement in all corners. The presence of power plants sometimes do not solve the need for electricity especially in remote areas where the terrain is always an excuse. Here an alternative energy that can be easily found in nature and can be used as an alternative free energy replacing conventional electricity, because it can turn on household electronics such as televisions, radios and lights.

Solar cells made from pieces of a very small silicon coated with special chemicals to form the basis of solar cells. Solar cells generally have a minimum thickness of 0.3 mm is made from semiconductor materials incision with positive and negative poles. Each solar cell produces usually voltage 0.5 volts. Solar cells is an active element (semiconductor) that utilizes photovoltaic effect to transform solar energy into electrical energy.

Solar cells contain a connection (junction) between two thin layers made of semiconductor materials, each of which is known as a semiconductor type “P” (positive) and semiconductor type “N” (negative).

N-type semiconductor made of silicon crystals and there are also some other materials (typically phosphorus) within the limits that these materials can provide an excess of free electrons.

Electrons are sub atomic particles are negatively charged, so that the silicon alloy in this case known as N-type semiconductor (Negative). P-type semiconductor made of silicon crystal in which there is a small amount of other material (typically boron) which caused the shortage of material free electrons. Lack or loss of electrons is called a hole. Because there is no or lack of electrons electrically negative charged then the silicon alloys in this case as a semiconductor type-P (Positive).

Composition of a solar cell, the same as a diode, consisting of two layers, called PN junction. PN junction obtained by staining a pure semiconductor silicon (valence 4) with the impurity valence 3 on the left side, and one on the right impurity stained with valence 5.

The effect of the electric field in a PV cell

Operation of a PV cell

Basic structure of a generic silicon PV cell

Thus formed on the left side that is not pure silicon again and called P type silicon, while the right side is called silicon type N. In the pure silicon there are two kinds of electrical charge carriers are balanced. Positive electric charge carriers called holes, while the negative are called electrons. After a desecration process, in the P type silicon formed holes (positive charge carriers) in a very large number compared with the electron. Therefore, in the P type silicon holes are majority charge carriers, while the electrons are minority carriers. Conversely, in the N type silicon is formed of electrons in a very large number so-called majority carriers, and holes called minority carriers.

In the silicon rod there was interaction between the P and the N. Therefore called the PN junction. When present, the P associated with the positive pole of a battery, while the negative polar associated with the N, then there is a relationship called “forward bias”.

Under forward bias, electrical currents arise in a series due to both types of charge carriers. So the electric current flowing in the PN junction is caused by the movement of electron and the movement of holes. An electric current is flowing in the direction of holes movement, but opposite direction with the movement of electrons. Just to further explain, electrons moving in the conductor material can lead to electrical energy. And electrical energy is called as an electric current that flows in the opposite direction to the movement of electrons.

But, if the P associated with negative pole of batteries and the N associated with positive pole, then now formed a relationship called “reverse bias”. In these circumstances, the hole (positive charge carriers) can be connected directly to the positive pole, while the electrons are also directly to the positive pole. So, clearly in the PN junction there is no movement of majority charge carriers either the holes or electrons. Meanwhile, the minority charge carriers (electrons) in the part P moves trying to reach the positive pole of the batteries. Similarly, the minority charge carriers (holes) in the N also moved to reach the negative pole. Therefore, in a state of reverse bias, in the PN junction there is also output current even in very small amounts (micro amperes). This current is often called the reverse saturation current or leakage current.

.
Anything interesting in reverse bias. When the temperature of PN junction raised they will be able to enlarge leakage current. Means that if given the energy (heat), the minority charge carriers in the PN junction grows. Because the light is one form of energy, so if there is light that hit a PN junction may also produce enough energy to generate charge carriers. This symptoms are called photoconductive. Based on the photoconductive symptoms made of photodiode electronic components from PN junction.

In reverse bias, with increasing intensity of light that hit photodiode can increase the level of leakage current. Leakage currents can also be enlarged by increasing the battery voltage (reverse voltage), but the addition of leakage currents were not significant. When the batteries in the reverse bias circuit is removed and replaced with a load of resistance, the provision of light that can cause charge carriers both holes and electrons. If the illumination light is increased, current output was greater. Such symptoms are called photovoltaic. Light can provide enough energy to enlarge the number of holes in the P and the number of electrons on the N. Based on the symptoms of this photovoltaic electronic components can be created photovoltaic cell. Because usually the sun as a source of light, the photovoltaic cell is also called the solar cell (solar cells) or a solar energy converter.
So the solar cell is essentially a large photo diode and designed by referring to the photovoltaic symptoms so that could produce the greatest possible power. P type silicon is the very thin surface layer so that light can penetrate directly reach the junction. Part P is given ring-shaped nickel layer, as a positive output terminal. Under the P is the N type that is coated with nickel as well as the negative output terminal.

To obtain a large enough power required much of solar cells. Usually, solar cells arranged form the shape of the panel, and is called the photovoltaic panels (PV). PV as a source of electric power was first used in satellites. Then PV as an energy source for cars, so there are solar electric car. Now, in foreign countries, PV has started to be used as a roof or wall of the house. Sanyo has made even a semi-transparent PV that can be used as a substitute for glass.

After getting the output of the solar cell is a direct electrical current can be used to load utilized. But also the electric current can be used as a charge stored by the battery to be used when needed, especially at night because there was no sun.

If the solar cell is used for storage into the battery, then the resulting voltage magnitude must be above the battery specification. For example the battery used is 12 volts, the voltage produced by solar cell must be above 12 volts in order to perform charging.

We recommend that before carrying out the charging battery should be empty because the incoming flow will be filled with the maximum. The unit capacity of a battery is the Ampere-hour (Ah) and these characteristics are usually found on the label of a battery. For example a battery with 10 Ah capacity will fill up for 10 hours with the solar cell output currents of 1 Ampere.

Solar Residential Energy: What is it for?

Solar energy: this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar residential equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar residential energy has.

Why is the solar residential energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar residential energy is used, the electrical bills tremendously go down as compared to the other type of residential energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar residential energy?

Another major advantage of the solar residential energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your residential are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off light and they need not be turned off as well when they are no longer needed.

As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.

A List of the Benefits of Solar Residential Energy

Why is the solar residential energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:

Solar residential energy is environmentally friendly. As mentioned a while ago, solar residential energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.

Solar residential energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills.

Solar residential energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar residential energy.

Making use of the solar residential energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.

Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.

Some Common Disadvantages of the Solar Residential Energy

Of course the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar residential energy:

The employment of a solar residential energy can be expensive at first. But as time passes by, it becomes light to the pocket.

The strength of the solar residential energy will relatively depend on the location of your residence in relation with its facing to the sun. Also, the area of your residence is another point to consider. You will need large areas to install the solar panels.

The Various Solar Energy Items

There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.

What You Must Do

Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar residential energy. But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all. If you don’t have enough money to fund these items you can always start small.
