Solar Pool

July 14, 2011 By: Admin Category: Solar Heater

Solar Swimming Pool

Shallow water in a pond or lake tend to be more heat than the water that is in a deeper place. This occurs because the sun can warm a basic pond or lake in the area that is more shallow, and that means water that is above become hot.

With the same principle, the sun can be used as a water heater in the building and swimming pool. Most of the water heating system that uses the sun as a source of heat, consists of two main parts: the sun collectors and storage tanks. Collectors that are commonly used flat plate collectors. Collector consists of thin flat box with a transparent top cover part and facing towards the sun. Small pipes that is in the box bring liquids, which can be water or other liquids, to be heated. Pipes is paired on the black plate that serves to absorb heat from the sun. After a heat form in the collector, the liquid is in the pipes will be hot.

Solar Applications

June 21, 2011 By: Admin Category: Solar Power

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

AQUASUN by Solaris Synergy and EDF Group

One of the things that a potential obstacle in the development of solar energy is limited space. All existing solar panels in a solar power generation should receive sunlight for at least the same intensity to produce electrical energy optimally. Therefore, all the solar panels should be installed in rows, which mean that also require large open space.

In addition, the performance of solar panels that are widely used today are still influenced by the temperature generated by the environment and direct sunlight. The higher the temperature, the performance of a solar panel will also decrease.

Top Guide Of Home Solar

Home solar power could actually fun, modern, and even interesting. Limited electricity does not mean sacrificing convenience and comfort provided by the air heater, water heater, and air conditioning.
The design of home solar will save electricity because the walls, windows and floors designed to absorb and store heat energy during the winter and distribute them. And dissipates heat during the summer. Therefore comfort provided by the heating and air conditioning can be displaced.

Here are five basic elements that must be interconnected with each other in designing a home solar.

Collectors

The large glass windows that are directly related to the sun should be facing 30 degrees to the north and should not be obstructed by other buildings or log starting at 9 am to 3 pm.

Absorbent

Walls, floors and partitions are objects that can absorb and store heat.

Thermal mass

Thermal mass is a material that can store heat from solar energy and is located behind the surface of objects that can absorb heat like the floor.

Distribution

Heat that has been collected and stored, then distributed or in circulation from one room to another. Method to distribute this is conduction, convection and radiation.

Setting

Control tools should be used to utilize energy use that has been collected, such as a thermostat to check the temperature so that it can turn on and off the fan.

How to Take Care for Solar Water Heaters

Various household needs to be more practical because the presence of technology. One technology that is now beginning to be the belle of the houses is the water heater technology.

At least there are three types of water heaters available on the market. The third type is the water heater with electric power, gas, and solar. If you want to purchase one of the three types of water heater, do not forget to consider safety factors, thrift, and comfort, You can see these factors from the various features on it. Solar Water Heater more practical and energy efficient because it uses solar power.

Choosing a water heater with superior features make your water heater work maximum and durable. In addition, there are two ways to keep the water heater remains preserved.

First, consider whether the magnesium anode in the tank is still working to keep water pH neutral in the number 7. Usually, the areas of clean water, magnesium anode can hold up to 5 years. However, in areas that lack clean water, the magnesium anode should be replaced once every year.

If not replaced, the water in the tank will become acidic (if pH above 7) and becomes alkaline (if pH below 7) is harmful to health. In addition, the tank will gradually run into corrosion that can lead to leakage.

Second, check the safety valve periodically. Safety valve is a kind of excess pressure safety device on the tank. This tool will keep the tank temperature remains stable. To avoid blockage of water, raise the safety valve lever periodically.

Solar Water Heating

November 15, 2009 By: Admin Category: Solar Heater

Benefits of Solar Water Heating

The fuel needed to heat water can be reduced by solar water heaters because it capture renewable energy, the sun. Many solar water heaters use a small solar electric (photovoltaic) module to power the pump needed to circulate the heat transfer fluid through the collector. Use of these modules allows solar water heater to operate even during a power outage.

Solar water heaters can also be used for hotels and motels, car washing, swimming pools, restaurants, and others.

There are many designs for solar water heaters. But, in general consists of three main components:
1. Solar collectors, which convert solar radiation into heat.
2. Heat exchanger / pump module, which transfers heat from solar collectors into drinking water.
3. Storage tank to store solar hot water.

The most common types of solar collectors used in solar water heaters is a flat plate and evacuated tube collectors. In both cases, one or more collectors are installed on the south facing slope or roof and connected to the storage tank. When there is enough sunlight, a heat transfer fluid, such as water or glycol, is pumped through the collector. When the fluid through the collector, he is heated by the sun. Fluid which is heated and then circulated to heat exchangers, which transfer energy into the water tank.

When the owner of the home using hot water, cold water from the main water into the bottom of the solar storage tank. Solar hot water at the top of the storage tank flows into the conventional water heater and then to the faucet. If the water at the top of the solar storage tank hot enough, no further heating is required. If the solar-heated water is not too hot (because the clouds long enough), a conventional water heaters heat water until the desired temperature.

What To Expect From Solar Power Home?

Many people, especially those who are beginners in solar technology may wonder how solar panels work. But first, what is the home solar panels? This is a solar-powered gadget that collect and use the energy from the sun through its rays and convert it into power.

Some people use solar panels home gadgets to act as an alternative source of energy for their small household, effectively complements the consumption of electricity from local utilities.

There are still homeowners who invest in residential solar panels are fully able to provide power to the house, run all appliances, water heaters and swimming pool. However, the cost is very expensive if you intend to own and install your own home solar panels that will work as the only source of daily strength. A solar panel unit actually has a very high price from a few thousand dollars.

How solar panels work can be answered simply. He has a photovoltaic cell in a panel that primarily works by collecting energy from sunlight that falls on them, then solar energy is converted into electrical energy for use at home.

You may very well consider this gadget as an investment, because you need to shell out large enough amount of money to buy and install them as your resource. It is a serious investment even if you only need to spend the money early, the amount needed is really great. After purchase you do not have to worry about this as the sun runs his own gadgets, making endless supply of electricity to your residence with the help, of course, the sun.

Many supporters of a clean environment and recommended the use of green house solar panels, if only because the energy that collects and converts power from the sun. Therefore, the power generated is clean and not harmful to the environment of the world. Likewise, you do not have to worry about running out of the sun’s energy for endless supply. Solar energy is a clean renewable energy, and is considered the best alternative energy is there.

Collector Solar

July 08, 2009 By: Admin Category: Solar Accessories

Flat Collector

Flat collectors, and even concentrator is a tool used to collect solar radiation energy so that thermal energy produced can be used in more practical for a variety of processes. Flat solar collector consists of a transparent cover, absorber and insulator. Solar radiation that falls on the surface of the transparent material in the short wave will be forwarded by transparent material and then absorbed by absorber. Black color have an ability to absorb a larger radiation so that most of the sun radiation will be absorbed. Absorption of this radiation will create a high temperature absorber. Heat radiation emanated by absorber but in the form of long waves. Most of the transparent material has an opaque nature of long wave radiation and therefore part of the long wave radiation reflected back by this transparent material to the absorber. Some radiation is absorbed will be reflected back and the rest will experience the same process that is part reflected back to the absorber. Thus, the loss of heat due to radiation can be minimized by flat collector. In addition, the transparent cover also functions as a heat loss barrier carried by the air above the absorber to the environment.

Heat from the absorber is used through heat exchanger to the media of heat carrier. Media of heat carrier commonly used can be air or water. When using water as the media, absorber will conduct heat to the surface of the outside pipes. Then take heat conduction from the outside surface to the inside surface. With the process of convection, heat will move from the inside surface to the water that flows in the pipes, so the water temperature will increase. Water with a high temperature and then used in the other parts of the outside collectors flat. A similar process occurs when air is used as a medium of heat, but in this case the pipe is rarely used. The air above (or below) the absorber heated through convection due to direct contact with the absorber. High temperature air is then flowed out of collectors than used in processes that require hot air.

The performance of a solar collector will depend on the absorptivity characteristics of the absorber, transmissivity of transparent material, overall heat transfer coefficient of the insulator, the transparent material and the absorber.

Absorptivity is the portion of light that is absorbed by an object; transmissivity is the portion of light that is forwarded by an object, while the overall heat transfer coefficient is a power of heat transfer or the opposite of heat resistant.

Active and Passive Solar Heat

Utilization of solar energy in architecture can be done in two ways: passive and active. Utilization of passive do when solar power does not need to converted first into electricity. Deep utilization of the passive is also included on space heating (using the greenhouse gases) for the region with temperature of the air low, and water heating. Also, techniques to prevent heating the air in the room on the building in the area, including Tropical into the use of the passive type, where component of sunlight, which consists of: light and heat, only used on components’ light ‘it – the need for natural lighting in buildings.

Passive design strategies will be very different between the buildings that are on climate Tropical and climate Sub Tropical / cold. At the Tropical climate, direct radiation from the sun tend to be avoided by building in order to heat gain in the building to be low, so the increase of air temperature in the building can be prevented. While in Sub-Tropical climate, the design strategy is a passive step of the Tropical climate strategy in the acquisition of heat sun tend to be maximized (except in the summer), solar radiation through that fall directly on the building so that temperature increase occurs in the building, considering the air temperature around is low.

In utilizing the solar actively using the photovoltaic, should also simultaneously architect implement the strategy of passive design. Without the application of passive design strategies, energy use in buildings very likely remain high when visual and thermal comfort must be achieved. In situations such as this, the electric power comes from solar power conversion by solar cells does not become too much meaning. With dimensional solar cell panel which needs large electricity for the achievement of thermal comfort and visual on the building difficult to fulfill. Still electrical energy required for engine cooling air with a large capacity, because the air temperature in a high building, also required electricity for lights in the torch-lighting building a dark room when the strategy passive design that lead to the energy savings are not applied. Role of solar power to replace electricity necessary to achieve the building comfort (thermal and visual) finally failed because the building was not designed in such a form so that comfort achieved without the many electric energy consumption. Electricity generated by the photovoltaic possibility will not be large enough to cool down and illuminate the building. In other words passive design considerations for the use of energy in buildings in this case can not be ignored.

In the passive design, objectives of architecture work that would be achieved – that is comfortable and aesthetic, are generally made integral. Each step in the preparation of the components to form the jacket, simultaneous will result in the achievement of buildings comfort and aesthetic. Be not so with the case where the design of active solar cell panels can be arranged separate components with the preparation of building casing. In other words, the achievement of building aesthetic in active design done in a more flexible and separate with the strategy of comfort achievement, although in fact the architects are required to thought to integrate a comprehensive comfort needs with aesthetics – between needs using a solar cell panel with place them on the integrated shroud of the building so that the panels at once can be a building aesthetic element.
