Global warming, energy crises and greenhouse effects are worldwide concerns. All countries are insistently pursuing other safe alternatives of energy sources. Solar system is on top priority list among other alternative sources of energy. Countries are investing extra money in the field of research for the development of a solar energy system.

Solar system produces 0.1 percent of electricity in U.S.A. It will increase up to 10 percent. It offers competitive cost than other sources of energy.

Competitive Costs

Some factors influence the costs of a solar system. The Size of a system, required energy and a location of installation, set price of a solar system. Average cost of an installed system roughly estimated about $36,000 for a home of 2500 square foot.  This estimated cost is about 4 Kwh at $9 per watt. This estimation is not accurate. It just provides an idea of the cost.

Determine Size Of Solar System

The size of a home does not determine the size and the consumption of a solar system. Just call a representative and ask him to calculate the size of a solar system for your home. He will call your utility power company and get your monthly or daily electric usage in kilowatt hours. This information is also available in the copies of electric bills.

Tax Credits And Rebates

High Costs of Electricity in USA dissatisfy thousands of utility consumers. They enjoyed tax credits and generous discounts. Credits and discounts are available for the installation of solar electric system for household and business venues. The State of California for instance offers 15% tax credit and $4000.00 (per kilowatt) as a cash rebate for the solar electric system.

Photovoltaic panels

New solar system generates free energy from the sun and runs TVs, refrigerators, pumps, computers and many other appliances. Photovoltaic panels produce power directly through sunlight. Photovoltaic panels use semiconductors made up of various components. These panels are first preference of residential solar system.

Solar Thermal Collectors

This is another way of trapping, absorbing and transferring heat from sunlight in the form of warm water or air.  Solar energy system has a long way to go. It moves in a right direction with better incentives.

Configuration Of Solar Electric System

When one creates a solar energy system, the important thing that is kept in mind is the method of collection. This is very important because if you want your solar energy system to be successful it must have an efficient collector which is able to collect energy from the sun in the best way possible. In the market one can find mainly three different types of collectors but the most popular and the most widely used collector in the market today is the Flat Plate collector.

What is A Flat Plate Collector?

What is A Flat Plate Collector

A flat plate collector basically consists of a rectangular box which is covered by a plastic glazing or a glass, and underneath this covering lays a metal plate. The heat is trapped in the rectangular box with the help of the plastic glazing or the glass covering. This heat is then absorbed by the metal plate which is colored to absorb maximum heat. This absorbed heat is then transferred to tubes which contain air or water. These tubes then carry this absorbed heat around the house and keep the house warm without the need of any heavy electrical appliances

Air and Liquid systems

There are two types of systems. One system contains air in the tubes and the other system contains liquid in the carrying tubes.

Air Systems

Air systems in which heat is carried around with the help of air are not very efficient. Read the full story

It may be true that electricity is not the basic necessity of life but its deprivation can cause us difficulties in accessing the basic necessities of life. Where there are no power lines life becomes quite difficult to spend, but now thanks to the sun we can now take benefit of solar energy.

Solar pumps are a clean and very simple alternative to fuel-burning generators and of course windmills. Solar pump has the ability to produce more water as compared to a windmill or generator even in the harsh climate. Solar pumps are basically designed in such a way that they utilize DC power supply from the panels consisting of photovoltaic cells. Solar pumps can also be modified to operate on AC power supply.

Solar Pumps

Solar Pumps

Solar water pumps are designed in such a way that they only use DC electric supply from a panel consisting of photovoltaic cells. They must operate at low power during the low light conditions. They must not be stalled or over heated.

Low pumps utilize low volumetric mechanisms due to which the water is sealed in the cavities and forced upward. Where there is a need for high volumes of water then centrifugal pumps are used.

Surface pumps are mounted on the ground level, whereas submersible pumps are lowered into water. Submersible pumps are quite common in deep water wells.

Pump Controller

Pump controller is also known as the current booster. It is an electronic device utilized by most of the solar pumps. It works like an automatic transmission device.

It helps the pump to start and preventing it stalling in case of weak sunlight.

Solar Tracker

Solar pumps are also fitted with solar trackers. Solar trackers adjust the PV array according to the position of the sun, thereby increasing the energy gain up to 55%.Where there is availability of more peak sun hours then overall cost can be reduced by employing a smaller pump and a smaller power supply.

Tracking is efficient most when the weather is clear and sunny, at the same time it is less effective as the weather turns cloudy and cold.

Storage

The most important part is that of storage. Storage depends upon the climate and the usage of water. It may be possible that only three to four days storage may be required. For the sake of simplicity and economy some systems use water storage rather than batteries. A float switch is fitted in the pump which turns the pump off when the water tank is filled, so as to prevent the overflow and wasting of water.

Advantages Of Solar Pumps

Comparison of a solar pump and a windmill is quite meaning less as the solar pumps are quite easy to install and maintain as compared to the windmill and also they are less expensive.

Livestock Watering

Solar pumps are used for watering the livestock. Cattle ranchers enthusiastically use solar pumps. Read the full story

The main focused area of solar gable fans is the top floor ventilation. It contributes to the air flow throughout the entire home during the ventilation process. The solar gable fans are installed on the exterior of the gable end on the top hat portion of the gable exterior wall that extends up above the wall end of the home and onto the end of the supporting device that is holding up the roof. The end of the attic is signified by the gable ends and gable ends are the best place for a fan. Most often gable ends are also installed with the vents to allow air flow through the attic.

Electric Attic Fans vs Solar Fans

Electric Attic Fans vs Solar Fans

In certain cases, electric attic fans are also deployed on gable ends in order to increase the air flow and to ensure better ventilation. However, conventional fans that are wired into the electrical system of the home, increase the utility bills and add tax that electrical system. On the other hand, solar gable fans have proved to be a feasible alternative. These fans offer al the benefits of the electric fans and the best thing about gable fans is that they don’t carry the drawbacks like the conventional electric fans. Most homeowners can choose to deploy the fan without any external help because the installation of fan does not require wiring. Read the full story

Solar Pool Heaters are Cost-Effective

Solar Pool Heaters are Cost-Effective

The only expense that is required to use to solar pool heaters is applied at the time of the installation. Solar pool heaters cost you only the initial cost of these heaters. After that it doesn’t cost you anything to run and operate solar pool heaters because these heaters run solely on sun energy that is free.

Working of Solar Pool Heaters

The solar pool heaters work on a very simple principal. After that is stored in a collector is heated by the sunlight. This heated water is pumped back into the pool and increases the overall temperature of pool.

Solar pool heaters work only in the presence of day light, so it means that they will also work during cloudy days. But in the presence of direct sunlight, solar pool heaters are stronger and more effective. If you are living in an area where most of the time days remain gloomy then you need to install additional solar panels. It is important to increase the strength of solar pool heaters.

The Need Of Solar Power

Solar power is basically a clean renewable energy. About 50 years ago, it was not of major concern. But these it can be considered as something, which can save this planet. Green house gases are produced as a result of our requirement to fuel our homes, cars, boats and other things are speeding up the climatic changes.

Natural resources of the planet are depleting and also getting destroyed because of our extreme and unnecessary use of energy. So in order to produce energy, we have to find new means. By employing the energy of the sun, we can provide energy to these items, but in such a manner which has a positive influence and is friendly as well. And since the sun will always be there, so it ensures the clean energy use for the foreseeable future as well.

Cost Of Solar System Panels:

There is no cost for solar power as energy from the sun has no charges. The cost is only in terms of the products required for the collection and distribution of energy. Unluckily, the prices of these solar panel systems are very high and in most of the cases cost-prohibitive. Even those people in turkey, who are residing in caves, are using solar panels for the sake of creating energy and heating their water. Read the full story

Typically, one sort of energy, known as “free of cost energy” is a widely discussed issue now a days. With the advent of appropriate scientific developments we can extract the energy directly from the atmosphere, and which is unlimited in supply. The discussions are mainly about its availability or non-availability, and if available the supply is unlimited or not, and if it is available the costs involved in making it available.

What it Free Energy

The discussions also involve the verification of the claims of its supporters that it would be efficient to consume resources to investigate and cultivate it, as a probable alternative energy source.

The Basic Concept

The term “free energy gadget” has multiple notations when we talk about it. One of the possible outcomes of such a gadget is that it accumulates energy from a source which is not scientifically proven, and transfers it to the other source. And off course, it is free of cost too. It may also be some sort of a machine which accumulates cost free energy or a famous uninterrupted motion vehicle. Such an uninterrupted motion vehicle as its name suggests, it will move everlastingly and will never need to be refueled. It looks beyond the reality now. But it is not beyond the reality to develop such scientific techniques which may convert energy hovering in the environment.

Keeping in view the importance of geothermal energy we shall put all efforts to cultivate geothermal energy techniques. This is a field which has marvelous growth opportunities and it simply harvests the natural energy present under the surface of our planet Earth. There are huge reserves of geothermal energy under the surface of earth. What we have to do is go for it and connect to pipe it up.

The Science of Geothermal Energy

The temperature at centre of our planet the Earth is more than 60 times greater than the boiling point of water. Such a huge temperature generates massive pressure deep under the surface of earth. The vast pressure contains immense quantity of energy in the form of heat and pressure. The pressure so generated develops channels to come out of surface of earth. We can observe this energy when hot fluids called magma flare-up from volcanoes. The idea of geothermal energy is to convert this energy into electricity which we can use for our domestic and industrial consumption. A vast quantity of magma is present deep under the surface of earth. We have to locate such sites where the deposits of magma are large enough to run our project economically. Than we have to develop the channels to release underground pressure. Erect a power generation plant and produce power.

Geothermal energy is the heat available from the earth. Now this heat can come from two main sources. One, the heat coming from the sun and the other is heat coming from the center of the earth itself.Theoretically speaking the geothermal energy is enough to meet all the energy demands of humans. But this whole heating potential is not extractable.

Geothermal Energy Due to Sun

The top surface of the earth is baked by the sun during the day. The earth conducts this heat underneath the surface. The effect of this is more pronounced during the winters – when the temperatures a few meters underground are 10-15 degrees Celsius.

Geothermal Energy from the Earth’s Core

Geothermal Energy from the Earth’s Core

The other source of geothermal energy is the hot center of our earth. The center of the earth has very high temperature of up to 6000 Celsius. Places which are more prone to volcanic eruption are mostly suitable for extracting geothermal energy. The hot pools and geysers are other apparent forms of geothermal energy at our disposal. The geothermal energy from the center of earth can be extracted by digging for deep pipelines which will require more cost.

Comparison of the Two Sources

The geothermal energy due to absorption of heat from sun rays is more uniform and can be used anywhere. This heat is mostly used to warm up the homes in cold countries.
