In this current technology world no one would prefer bringing utility company power lines to any new remote area. The main disadvantage in bringing the power lines from any utility company costs a person hundreds and thousands per each foot.
Solar and wind generators can be considered as a solution of above expensive problem. Furthermore, person can free himself from expenses of monthly electricity bill.
Important Features:
1. A person pay far less as compare to utility companies to bring power to your remote area.
2. No more Monthly ongoing bills.
3. Now by the existence of this technology no more power poles required. That in return increases the resale of a person’s property.
There are many configurations some of which are discussed below.
DC Only System:
To maintain a charge in the batteries, small wind generating system or solar array is used. It is important that such system should be used in small cabin. And make sure that all appliances should be operated with DC only. As a matter of fact, DC appliances are more expensive then the AC one. But in long run it would be a better choice. DC appliances could be bought from RV supply houses.
Size Of DC System:
First thing to be considered is size. Size of the solar module or wind generator must be very appropriate. So that it could easily fulfill the power requirement of one day. It creates no disturbance in the efficiency.
Mounting Kit Of DC System:
DC system requires a mounting kit whose duty is to mount systems on the roof or on any open place near the cabin. These modules are normally mounted either flat or a bit tilted. A rack should be used that could be tilted. So at noon time module can point itself directly towards the sun.
Resistant Wire Of DC System:
Sunlight resistant wire, generally of 10 gauges whose main quality is its protective sheath. That can work for a long time in exposure without any harm. It may excel the efficiency of the DC System.
Charge Controller:
A charge controller is required in solar modules that could prohibit the overcharging of the batteries. It also resists in draining back of the batteries. Usually, in small wind generator we have charge controller built in. So an external charge controller is not elementary in wind generators.
Fuse Holder:
A protective fuse and fuse holder, of about 10 to 50 amps. It’s important that fuse should be deployed close to the battery. It must be connected to the positive terminal of the battery. Fuse amperes could vary with the number of modules in the cabin.
DC Distribution Panel:
A fused DC distribution panel is required in order to distribute the Voltage all over in the cabin. Distribution can be made by direct connection or female cigarette outlets could be used. It regulates the voltage level.
Powerful Batteries:
Some very deep cycle batteries of appropriate size can manage with the loads. That is supposed to take power from this bank. Batteries must be powerful so that after day consumption it should not be discharged below 50%. It is to be noted, for long life of batteries they must not be discharged below 50%.
DC/AC System without AC Powered Charger:
The construction of such is totally similar to the DC only system with one additional component known as inverter. The purpose of inverter is that it changes DC in AC electricity. This AC electricity can then further be used in household components as microwave ovens, computers, fans etc. One another change in this system is that regular household AC outlets. It took place instead of cigarette lighter outlets.
Powerful Invertors:
Inverter used must be enough powerful so that it can produce continuous power to run the appliances smoothly. Secondly, inverter must have high surge so that heavy loads such as motor, microwave etc. could be easily started.
Size Of Invertors:
Appropriate size of inverter DC cables is very important. The size of the cables must be suitable in both length and diameter. It’s highly recommended that 10 feet 4/0 cable is used with the inverter that is rated 12 Volts at 1500 watts.
DC Fuse:
DC fuse or disconnect would be required of appropriate rate. Similar to DC only system it must also be deployed to battery. It should be connected with the positive terminal. Use the fuse that is specially designed for DC use, or else your equipment would be of no use. The bad thing is it may result fire in the cabinet.
AC Circuit Breaker:
AC circuit breaker panel must be used for the protection of inverter and the loads. The panel should be mounted between inverters and loads. It increase the protection and safety.
Inverter Types
There are two basic types of inverter that converts DC to AC. First one is Modified sine wave Inverter and the other is pure sine wave Inverter.
Modified Sine Wave Inverter:
Modified inverter is the one that produces a sine wave that is approximately similar to the one produced by the utility company. This inverter is very efficient, reliable and required no virtual maintenance.
Sine Wave Acts Like Square Wave:
Sine wave produced by Modified sine wave inverter is like a square wave. Frequency and Voltage is constant that do not allow brownouts or spikes. As seen with utility company power. Appliances like stereos, computers, TV’s, inkjet printers etc. are preferred to be run on modified sine wave inverter. Today 95% cabins are enriched with such type of inverter.
Pure Sine Wave Inverter:
This is the type of inverter that produces exactly the same sine wave, as the one produced by the utility companies. It also prevents brownouts and spikes. It’s less efficient as compared with the modified sine wave.

The light rays of sun also heat the environment and thereby they promote life on our planet. The new advancements in field of science and technology have developed ways and means to cap the potential of the sun rays. These solar rays are used by the photovoltaic cells for production of electric current. These energy rays are also being used to heat different appliances using the passive heating concept.
Indirect Gain
Indirect gain is a means to achieving indirect or passive solar heating. This technique involves transfer of heat energy though the principle of convection. The heat energy is transported from one medium to the other without the use of the hydraulics of pumps. The heat energy is collected in one part of the building and is transferred to the other by the principles of heat exchange. Nowadays different means of using indirect gain are being incorporated in the building structures to heat by passive solar heating.
Few of the means of achieving indirect gain in buildings are as below:-
Use Of Roof Ponds
In this technique, a set of collapsible ponds are filled with water and these are placed on the roofs during the day time.

Companies all over the world are striving to develop the energy resources. With the declining oil and gas reserves of the world, people are looking towards alternate energy sources. Now the powers of the winds are being harnessed, ethanol is being produced, but by far the most potent source remains the sun.
The sun not only powers life on the plant, its energy in form of light can be converted into electrical energy.This energy is being utilized world over though lot needs to be done in this field.
Evolution Of British Petroleum
British Petroleum remains one of the largest private oil exploration and marketing company of the world. It ranks third amongst the world energy companies. The company had been investing in oil and gas worldwide but as these resources are decreasing, and in a response to global warming and green house effect awareness, the company is switching itself to alternate and safer energy resources.
Renaming The British Petroleum
Petroleum and gas no longer remain the sole energy sources of the modern world. In order to absorb this reality, the British Petroleum has also modified its philosophy and company outlook. The biggest step that they took in 2000 was to change the name from British Petroleum to Beyond Petroleum. This name signifies that the company does not deal in petroleum alone, rather it is open to all the energy sources including solar and nuclear.
BP And Solar Energy
The biggest respite to solar energy investors came once BP signed a deal with the Home Depot. This deal aimed at providing the solar panels for domestic users. The program advanced further once BP acquired Lucas Energy Systems in 1980 and also later on they bought Amoco and Solarex in 2000.

Natural resources of fuel are at a risk of being eliminated due to their consumption in very large amount. Scientist are trying to find new ways of producing fuel. One of them is the solar energy. Solar systems have been invented which convert heat energy into electricity. These solar systems are now in use and are cheap source of electricity. To understand the whole working of the solar energy systems, one must understand about the basic thing that is “Solar cell”.
Use Of Silicon In Solar Cells
The world has progressed rapidly in the field of solar energy. It is easy to use and is cheapest form of energy. To understand about solar energy system, one must start from basic level.,, a solar cell. The basic component of the solar cell is the semiconductor used to convert heat energy into electric charge. Many elements are now being used for this purpose but the best element that has been used from a long time and is still a part of many solar devices is Silicon. The guide line for solar cells is provided by the silicon structure in a photovoltaic (PV) cell. The current is produced in these cells by movement of the electrons from their respective shells. To move more electrons, additional impurities are added in silicon.
Producing Electricity From Solar Cell
A solar grade is made up with a crystalline structure. Semiconductor used in the cells is Silicon atom having three layers holding electrons. The no. of electrons increase in the center of atom. When the electrons from the outer shell of silicon escape, electrons from inner shells move to replace them. This moving results in creating a locked structure. Due to this reason, most of the silicon solar cells ape P-type or N-type silicon cells. N-type cells are added with the impurity that is mainly phosphorous which helps more electrons to escape from the outermost cell of silicon atom. Read the full story

Solar energy is being used by people from a long time. However, with the help of new techniques, solar energy has enabled us to perform a number of functions that were not possible before on such a low cost. Solar energy is being converted to a number of other forms including electricity and heat.
Solar cooling
Solar cooling towers are one of the most incredible applications of solar energy systems. This cooling system is a very practical use of solar energy, which is being used by people to cool their houses from centuries. This system is not only used for houses, but you can also use it for cooling commercial buildings.
Solar power combination
We can regard the solar cooling system as a type of geothermal or solar power combination. When it comes to the structure of a solar cooling system, one major p-art comes in mind that is corrugated pipes. These pipes are laid in the trench that has a dimension of five to ten feet below grade. The pipe is long enough to cover a large area that is meant to be cooled.
Movement of water through pipes
To allow the condense water to run out of the building, these pipes are provided with drainage holes. These holes are present at the bottom of the system or on the top of the gravel bed. This enables the water to run in a straight line and out of the house or the building. Read the full story

Solar technology continues to advance and most products of solar cell technology are under research. In the year 2002, a well known group of U.C Berkley chemists first time discovered a feasible way to manufacture plastic solar cells. Even though, plastic solar cells that were manufactured by using this innovative method were not as efficient as standard solar or photovoltaic cells of that time. However, the new technology brought many useful aspects with it like affordability, flexibility and potential to give renewable electricity.
New Advancements in the Solar Cell Technology
Due to the flexibility of plastic, the new technology widened the horizon of solar cell technology. Solar or photovoltaic cells were directly placed into the plastic in which there were tiny nanorods were dispersed between the electrodes. The entire device could be painted or sprayed on materials like clothing or other materials. On such materials the device would generate sufficient electricity to power radios, low-power devices and small computers. These devices are far more convenient than the huge and heavy solar panels that need a confusing or more complex installation. The installation of heavy solar panels can be done only with the help of expert solar contractors.
Increased Power of plastic Solar Cells
The power of plastic solar had increased to great extent since the year 2002, when these cells practically started producing 0.7 volts at the efficiency of 1.7 percent. By the year 2005, these solar cells became able to convert up to 6 percent captured sun power into energy. Read the full story

Although it is solar hot water systems are most common in use nowadays but the technology and the new home designs are getting advance day by day. There are some active and some passive home applications for solar cooling.
Active Systems
Solar desiccant and solar absorption are the two major kinds of active systems in these days for homes. Other actives systems include solar powered ventilation and solar “swamp coolers”.
Passive Systems
Solar cooling towers and passive solar ventilation are home design methods. Solar attic fans and solar gable fans are easily available and very low cot recourses. There are a number of benefits of solar air conditioning and ventilation.
Solar Compressor Cooler
Solar compressor coolers and the conventional air conditioning or refrigeration systems are similar. Electrical compressor is powered by the solar energy. The air is being passed through a condenser after being compressed and heated. This is absorbed by the condenser and air cool air is produced as a result. The absorption system can be single-, double-, and triple-effect cooler would be more efficient if there are more cycles.
Photovoltaic
Compressor based refrigeration systems can be powered by photovoltaic as well. They are more commonly used in Asia. Read the full story
