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.

Sun is the source of energy for our entire planet. It not only provides us the light during the day, it is also useful in regulating the temperature of our planet. 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.

Solar Energy

Solar Energy

During one hour, the solar energy coming from the sun is enough for the world’s energy need for more than one year. Energy obtained this way does not need presence of sunlight all the time. The method used to convert solar energy into electricity is called photovoltaic panel. Hence solar energy is an example of renewable energy.

Wind Energy

Wind turbines are used to capture wind energy. So the wind energy is another example of renewable energy.

Passive Solar Home

Electricity is not the only objective to be achieved by the renewable energy concept. Energy can be obtained and captured by some inactive home designing as well. Having the concepts of simple laws of energy can be very effective. According to law of energy, heat transfers itself from warm surfaces to the cooler in order to maintain the difference of temperature. Passive solar home can be designed by understanding this law.

Solar inverters are devices which convert direct current into alternating current. DC, commonly known as direct current is in a straight line form, and is not suitable for home appliances. We use AC or alternating current to run our domestic electronic devices. Solar inverters, as is evident from the name; work on the energy obtained from the sun.

 

How Electric Current is Produced?

Solar panels receive energy from the sun. This energy is in the form of light. Light is transferred to the photovoltaic cells which are mounted onto the solar panels. Photovoltaic cells are made of semiconductor layers of gallium or crystalline silicon. The semiconductors on the solar panel are connected through a junction, and contain both positive and negative layers.

When the heat reaches to the solar panels it is absorbed by the semiconductor elements affixed on them. The energy breaks the loose electrons of crystalline silicon or gallium. The loose electrons start a very fast motion from the negative layer of the photovoltaic cell to the positive layer of the cell. The fast motion of electrons produces electric current. The current generated because of the motion of the electrons in the solar panel is either stored into a battery for later use or is sent to the inverter.

Many people have knowledge about the electricity and all use electricity in their houses, schools, offices etc. But all people don’t know about the direct current and the alternate current DC and AC respectively. They also don’t know what the sources of these AC and DC current are. One should have their knowledge which is beneficial for their own convenience. Solar panels also work on watts and store energy on their panels.

AC and DC Current

electrical generation


Electricity flows in two ways; either it will be the alternate current of the direct current. Electricity is just the flow of electrons, which moves along a conductor. The conductor may be wires etc. The difference between these two is the direction or flow of electrons is different in AC current and different in DC current. In DC current the electrons go in forward direction but in AC current the electrons go in forward direction and then come back in backward direction. The electricity in wall lights which are being used by us in houses is the AC current. AC current is in the light sockets which are being installed in houses, schools etc.

DC Watts

DC Watts can be quote in two ways. One is known as Standard Test Condition and it is very simple you just take the watt from the panel and multiply it with other panel .

Understanding Climate and Weather

Tags: , , , , , , , ,


We all remember learning terms such as “climate” and “weather” back in our primary school days, but not all of us stay in touch with these (until commonly used) to be able to differentiate them. Let us take a look at what the weather of the earth is and what the climate is.

Climate of the Earth

climate of the Earth

The climate of the earth can be defined in different ways. It all depends on the speculations of the people. However, climate can be defined as the weather averaged for a long period of time. We can judge the climate, considering a number of years, by the rainfall and the changes in it’s amount, the pressure of the wind and the fluctuation of the temperature. Every place has a different climate. It depends on the location of the place, the sea level and the height from the sea level. Read the full story
