Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


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.

Using Solar Sunspaces In Homes

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


Sun rooms, green houses and “sun spaces” are a few terms that are often used interchangeably. But, there is a difference in all of these. It depends upon the purpose for which these are used. These are all used to retain heat from the sun. A brief note on all three is given below:

Sunrooms

It is a general term used for those home extensions that use natural light and windows. You can convert that extended area into reading room because it has ample light. It can also be used as an area for playing games. Kids would surely love that. Another option is to make it your prayer room or store sacred items in that.

Sunrooms don’t necessarily provide heating around the area. These are simple lighted extensions in a home that can be used in various forms.

Greenhouses

Greenhouses are especially made to hold back solar heat. This energy is needed for the growth of plants. Optimal conditions required by plants are not favorable for home living spaces. Moreover, in greenhouses it is important to control high temperature and excessive level of humidity. Otherwise, it is hard for plants to survive.

In a house attached with greenhouse, if windows are fixed in place of insulated walls, house can use more energy.

solar sunspaces and their purpose

Solar sunspaces work differently from greenhouses and sunrooms. These are supposed to collect solar heat that is distributed throughout the home. Since, there is no mechanical equipment or device needed; it is type of passive solar heating.

What are the main advantages of solar sunspaces?

Passive heating system has many advantages over active heating system. Sunspaces are built using techniques that integrate well into the design of a house. These go with the building structure and material, therefore these are not expensive.

Another benefit of solar sunspaces is that these are easy to maintain. There are no solar panels to clean or repair as in other active heating systems.

How sunspaces work?

A combination of direct and indirect solar heat gain is used in sunspaces. They can serve as storage area in the form of an attached room. Where is the solar collector in a sunspace? The space in the attached solar sun space acts as collector. It retains natural sun heat to keep room warm.

Many of the scientists are calling ethanol the fuel of the future.

Ethanol

Ethanol is the ethyl alcohol produced by the fermentation of sugars etc. This is used in drugs and as a part of alcohol for drinks. The same is also now used as a solvent and above all the fuel for vehicles. Ethanol gained worldwide publicity once an aircraft with this bio-fuel flew across Atlantic. Ethanol is gaining world wide popularity due to its safe nature for environment.

Advantages Of Ethanol

Ethanol is called as the fuel of the future. It is being used to power cars and buses and gives great mileage. It is cheaper as it is produced from the food crops like sugarcane. Furthermore, it’s burning yields minimal emissions of carbon dioxide and no other harmful gases are generated.
