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

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.

It looks as if it shall become the major source of power generation in a short time.

Solar Power Generation Prices are getting Competitive

The factor that till a few years back kept solar power from overtaking the power generation as a major production source was it being expensive. When compared with the coal generated power, the coal generated power was a remarkable 90% cheaper than the solar power generation. Now the changed and recession hit economy of the world has played a major role in bringing down the prices of solar panel from 10%—30% in the last six months. Contributed to this lowered price is also the investment that is making its way in this power generation means, an example being the 3 times lowered prices since May, of the Sharp solar panel from a $5/watt last year to $4/watt. Many of the projects which previously could not be considered would now become feasible because of this price decrease. Read the full story

Shifting from one source of energy to another could be the best way to curtail your energy bill per annum. With the passage of time and advancement in technology we have increased number of home electronic devices and machines who add our comfort level. One way to decrease the bill may be to avoid the use of such devices. Perhaps the better way to decrease the bill is to alter the sources of energy and shift to renewable energy sources. It will surprisingly cut down our energy bills and save our hard earned amounts. To build your own solar panel you need to have the approach to a workshop. Solar energy is one of the renewable sources of energy, which will generate electricity free of cost forever.

 Solar energy

When you decide to shift to solar energy you need to work out the quantity of energy that your system should generate.

You may acquire a compact solar power system that will reduce your power bill as much as ten percent or even your power bill may completely be eliminated. However, in practice the pretenders of the solar power system install solar panels to just get hot water, and later they completely shift to the solar power system for their entire domestic needs.

Photovoltaic Solar Panels

Understanding the functioning of Solar Panels

Like any other form of energy solar energy is also a form of energy. The laws of physics tell us that energy can be converted from one form into the other. Likewise solar energy can be converted into electricity or heat energy. The solar panels do the job; they convert light energy into electricity or heat. Combined with phosphorus, boron or other elements the solar panels are made from silicon plates. The aim is to create solar cells which produce negative and positive charges. The two thin solar panels i.e. photoelectric modules and solar thermal collector are microscopically thin rectangle boxes which absorb the sunlight and convert it to heat or electricity.

Why Solar panels?

The solar panels are more environment-friendly medium of energy. Compared to electricity, solar energy pollutes the environment to the least and does not emit harmful gases which prove harmful for the environment.
