The Ease And Convenience In Passive Solar Heating

Friday, July 30th, 2010

Who knew that the even the simplest concept of solar energy can be divided into a couple of other areas? In addition to heating using solar polymer heaters, there is such a thing as passive solar heating. However, you will find that this is not the more favored option when converting direct current to alternating current is concerned, if you ask for the popular opinion regarding this. However, when it comes to generating power and energy from the sun, this works just as efficiently and effectively. The fun fact is that maybe some of us are already using it without even knowing it! This may be due to the fact that, just as what its name suggest, this is a passive concept.

Passive solar heating is the process of using the sun’s natural energy for different means and purposes. This process is very convenient because maintenance and storage is not a problem.

How to Use Passive Solar Heating

The architecture and the construction of the house must be considered to extract the most benefits from passive solar heating. There are different structural issues that should be taken cared of. One of these is the places that get hit by the sunlight the most, or the number and type of windows that are directly exposed to the sun.

The way that the pieces of furniture and appliances are arranged must be considered too. Leaving a space for the sunlight to enter and to be absorbed is also important. Basically, the design of the house, or each room, must prioritize the sun and the amount of light it can shed on the structure.

To ensure more sunlight, the windows can be double-glazed with insulated frames. This way, the heat is stored when the sunlight hits the windows. The insulation also helps retain and store the heat. This is also a factor in reducing the requirement of heating for a particular room, which will only boost your home’s consumption of energy.

Why you should use passive solar heating

Passive solar heating gives a number of benefits, especially since the heat may be stored for quite some time. When the temperature tends to drop It can be very helpful during the winter months. This concept is also applied in keeping and maintaining greenhouses and solariums. With the help of solar tanks, water can also be heated through it.

Passive solar heating is also used when you employ solar lighting in homes and walkways. Charging batteries is also possible.

The heat in the windows cools off, as the day advances. With the help of solar mass, this may be prevented. The release of the heat is delayed by these materials. Commonly used materials are stones, rocks, water, an concrete. You can improvise by using jugs or bottles of water if you cannot get a hold of these. The smaller the container, the more heat will be absorbed and stored.

No one can deny that the sun provides different uses to man and to the environment. Passive solar heating is only one of them. Especially to those who need their homes heated, this is a very useful concept to people. It does not require much and is very practical, too. As a matter of fact, it can be as easy as putting drapes on your windows.

Take A Dip With Solar Swimming Pool Heaters

Friday, July 30th, 2010

It has been said time and again that the use of solar energy is advantageous and useful. It does not matter if the panels are installed in offices or on homes, they work perfectly the same. They work with just the same efficiency and they produce just as much electricity. Calculators have been working on solar energy for quite some time already. But, right now, every gadget, device, or appliance work and operate with it. Here is another good thing: they can be used as solar swimming pool heaters, too. And yes, taking advantage of this new technology had various benefits of its own.

In order to make solar swimming pool heaters, you need to gather a lot of parts. First, you need to gather the panels. In order to flow to the other parts, this part is where the water goes to. The water is heated by the sunlight because of this. To keep the pool clean for human use, of course, you need a pool filter. Any kind of obstruction, of course, needs to be removed. The water is deposited and transferred to the filtration and collection system using a pump. After the water is warmed and cleaned, it goes back to the pool through the pump. Lastly, a flow control device is assigned to take note of how much water is deposited to the solar collectors, so as to prevent it from overflowing. You can also choose to attach another valve to add reinforcement.

There are two types of solar swimming pool heaters. The two main types differ only in their composition. They may be glazed or they may be unglazed. You can choose between the two types, depending on how much you will use it and on where. The glazed ones cost more, most of the time. However, they have more uses. They are made by connecting a metal plumbing to an aluminum panel. The glaze is actually made from iron-tampered glass. For the unglazed types, the ultraviolet light is covered using durable rubber or plastic. You need to take good care of them to maintain their optimum efficiency, because they are less expensive.

The fact that solar swimming pool heaters can be made from scratch is a very good thing. Of course, this needs to be done with the right parts and materials. They work perfectly fine even if they could cost quite much too. However, before you start this task, you need to consider a few factors. First is the weather and sunlight availability. You should definitely mount them on the area that gets the most sun. Other considerations include the size of the pool, the frequency of use of the pool, and the preferred temperature of the water. You also need to make sure that the solar collector works as efficiently as possible.

By having solar swimming pool heaters installed in your house, you will rip the benefit that other heaters promise. Even if the temperature outside is not the best one to take a plunge, you will be able to wade in the water if you want to.

What To Know About Silicon Solar Cells

Friday, July 30th, 2010

A lot of solar panels, nowadays, consist of crystalline silicon solar cells. There are actually different kinds of solar cells, but they are the ones that are most commonly used. The primary function of these solar cells is to produce electricity that will power the whole household from the light of the sun. In order for them to work properly, they need to be covered with a semiconductor. They are often covered with silicon, and are connected in series, which are, then, connected to form arrays that will produce voltage. Once these are properly assembled, they are put behind a glass to “get” the sunlight. After the light absorption, the electrons are agitated and activated. As a result, energy is produced and then converted into direct electricity current.

There are three types of silicon solar cells. These types are the following: the ingot, the ribbon, and the wafer. They are very much appropriate to use and are quite thick. Because they actually do not cost much money, many people choose to use these solar cells. People who wish to have their own solar panels installed but cannot afford them, may choose to use these types of solar cells instead. Even if they are less efficient than the other types, they work out just fine. Perhaps, it can be attributed to the inexpensive and cheap materials that are used in its composition.

In fact, there are different “generation” types of silicon solar cells. Silicon cells are sliced into wafer-like shapes and piled on top of each other to create the first generation. This is perhaps the most common, because of its bulky size. The next of these types is known as the second generation. Despite the fact that they are composed more complexly, solar cells that belong to be in this type are generally more efficient. The third generation is known for not using silicon as a semiconductor. On the other hand, solar cells that do not use silicon are still not available for mass consumption.

If you compare silicon solar cells with organic photovoltaic cells, you will find that there is stiff competition between the two. The latter has the upper hand, if production efficiency is the main concern. In a short period of time, there are more photovoltaic cells and polymer cells produced. Compared to the number of silicon cells made in a year, there are bigger square meters of solar cells produced in an hour. But silicon solar cells are much better in terms of efficiency of performance. This is mainly due to the durability and the lifespan of these cells. It is found that silicon cells do not lead to events in the environment, such as oxidation and change in temperature, and can last 10 times longer than an organic photovoltaic cell can.

To lower the cost of buying individual solar cells, silicon cells were originally invented. To be able to develop solar cells made in thinner forms, more studies have been spearheaded. However, these proved to be less efficient. At present time, increasing the performance of these thinner cells have proven to be a challenge, because they are not competitive enough to be run with the others.

The Beauty Of Solar Energy Benefits

Friday, July 30th, 2010

It cannot be denied that nowadays more and more people are choosing to go green and use solar energy instead. As a matter of fact, there is no problem with that. Even better, there are various solar energy benefits that may be extracted from using these alternative sources of energy. The benefits are, in fact, endless and they are strong enough to serve as evidence that solar energy is the future.

First and foremost in the solar energy benefits is it helps a person save money. Think about it, there is no cost in utilizing the energy provided by the sun. It is very much free. The government also offers different incentives that will further reduce the cost of your electric bill. Furthermore, utility companies practice net metering, which involves buying the excess energy that your panels generate for you and crediting it to your account. Fuel is also not required by solar energy, which further limits your expenses. Using it is not dependent on fuel price fluctuations since it does not need fuel to function.

Being friendly to the environment is the second among the solar energy benefits. This should be a relief, seeing that the environment is on the edge of destruction and death. While gas, oil and fuel are not clean and renewable, solar energy is. It does not release harmful gases like carbon dioxide, nitrogen oxide and mercury. This means that this does not add up to the factors that cause environmental dangers such as acid rain and global warming. The emission of toxic greenhouse gases is also lessened.

The next among the solar energy benefits is its semi-independence. Different pieces of furniture and appliances are powered by the energy from the sun. Paying your electricity bill will also be much easier. This also eliminates the need to constantly worry about the power supply. Using solar power does not necessarily need gas grids. It can work perfectly on its own, so one can just tuck it away to another place with ease. One does not need to depend on other sources of energy, which also depend on environmental and natural events, With solar energy powering your household. This makes it a heavily stable energy source.

Another example of the solar energy benefits is its low maintenance cots. They can also last for a very long time and they are completely free of charge. One still gets to experience complete peace in the house because they operate silently. Because it does not emit any foul odors and smells, it is not distracting at all. You can easily have more panels installed if you need a bigger amount of solar energy in the future.

The benefits that solar energy will bring will continue to pile up after further studies are done regarding the matter. As of now, it seems like this resource does not pose any threat. Even if it eventually does, it is not destructive like the other energy sources. Recent times have definitely seen an increase in the use of this foolproof energy.
