Introduction of Solar Home System

 

Silicon remains the most popular material for solar cells, including these types:

  • Monocrystalline or single crystal silicon

  • Multicrystalline silicon

  • Polycrystalline silicon

  • Amorphous silicon.

     

The absorption coefficient of a material indicates how far light with a specific wavelength (or energy) can penetrate the material before being absorbed. A small absorption coefficient means that light is not readily absorbed by the material. Again, the absorption coefficient of a solar cell depends on two factors: the material making up the cell, and the wavelength or energy of the light being absorbed.

 

The band gap of a semiconductor material is an amount of energy. Specifically, the band gap is the minimum energy needed to move an electron from its bound state within an atom to a free state. This free state is where the electron can be involved in conduction. The lower energy level of a semiconductor is called the "valence band." The higher energy level where an electron is free to roam is called the "conduction band." The band gap (often symbolized by Eg) is the energy difference between the conduction band and valence band.

 

Solar cell material has an abrupt edge in its absorption coefficient; because light with energy below the material's bandgap cannot free an electron, it isn't absorbed.

 

Working Principle of Solar Roof System

 

The stand alone Solar Home System is an off-grid solar system which uses batteries to store the solar energy. Stand alone solar system solutions design for those who are not able or willing to connect to electricity grid.

Product Features of Solar Home System

 

1.    Off grid solar power system is mainly used for application with relatively-small power consumption, and the areas have no grid network coverage, or grid power is unstable or outage condition.  

 

2.    It’s composed of solar panels, hybrid solar inverter, battery bank, solar panel mounting racks, and other accessories required fora complete home solar power system.

 

 

3.    The battery bank gives a stable power output to the solar inverter which converts DC to AC to power loads, and provides power backup in rainy or cloudy days.

 

4.    The solar panels generate electricity at daytime and charge the battery bank.

 

5.    The off grid home solar power system provides grid power bypass in case of battery power shortage when sunshine is not enough.

 

6.     All the off grid home solar power system configurations are worked out by scientific calculation and design.

Q:What is the usage of solar cells?
Solar cells were first used as as an alternative power source to the primary battery power source.
Q:How can I explain to my 10 year old daughter what solar cells are?
According to Wikipedia: A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
Q:Which Solar Panel Type is best? Polycrystalline panel or PV Module Monocrystalline Solar cell panel, or thin film?
According to the calculation, The efficiency rates of monocrystalline solar panels are typically 15-20%, which proves that they are the most efficient one.
Q:How can the huge solar cells be applied into the market?
The huge solar cells are more used in the industrial project, which needs more power supply in one time. Without the huge solar cells, it might not be able to work at all.
Q:Where can I find more information about the work process of solar cells
From your teachers at school.
Q:Anybody ever heard of thin film solar cell? What it that?
Thin film is a kind of special material, known as TM.
Q:Is the Photovoltaic Cells cheap to buy?
If you are determined to get the solar cells to generate the power for you, Photovoltaic Cells are one of the cheapest things you can get.
Q:What is a good introduction of solar cell?
A professional presentation will be very impressive.
Q:Are there any library or exhibition halls where I can show students at school how the solar cells works?
Well, it is hard to say when there would be one talking about solar cells.
Q:I am a purchasing manager for a EPC engineering company, and we are planning to purchasing some 4bb solar cells for one of our project in Taiwan, can I get a quotation online?
I did the purchasing for my client once, and I found out you can get to talk to many sellers if you spend some time searching on alibaba.
