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:Have you ever been to a solar cell power generation station?
I know a company named SUNPOWER is famous for that.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
I am not sure about that.
Q:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
We have it, here are the details for your reference: 3-Busbar Solar Cell with the dimension 156mm*156mm+0.5mm thicknesswafer (si):200um+30um 180um+30um/-20um
Q:Are there any books in the market t about solar cells and their applications?
Yes, you can find it in the science and technology section
Q:What kind of products can be considered as the solar cell products?
I think there is nobody else but me could be as qualified to answer this question because 80% of my daily life is surrounded by solar cell product including solar cell shower room, solar cell equipt kitchen, solar cell control lights in all my rooms in the house.
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?
We do have 4bb solar cells, but we also have 125Mono &156 Multi&Mono 2BB&3BB&4BB A grade solar cell.
Q:How can the huge solar cells be applied into the market?
The huge solar cells, compared to the small one, can be more useful in some industries, such as the big factories consuming too much electricity per day.
Q:What is the working principle of a solar cell?
A solar cell is a solid-state electrical device (p-n junction) that converts the energy of light directly into electricity (DC) using the photovoltaic effect.
Q:My solar cells are broken, can I just buy one and replace it?
No, you just can not do properly
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
The installation is more expensive than using it.
