Mono vs. Poly solar panels 


Both monocrystalline and polycrystalline solar panels serve the same function in the overall solar PV system: they capture energy from the sun and turn it into electricity. They are also both made from silicon, which is used for solar panels because it is an abundant, very durable element. Many solar panel manufacturers produce both monocrystalline and polycrystalline panels.


Both mono and poly solar panels can be good choices for your home, but there are key differences between the two types of technology that you should understand before making your final solar purchase decision.


Monocrystalline solar panels

To make solar cells for monocrystalline solar panels, silicon is formed into bars and cut into wafers. These types of panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. Because the cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. As a result, monocrystalline panels are more efficient than their polycrystalline counterparts.


Polycrystalline solar panels

Polycrystalline solar panels are also made from silicon. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel. Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.


FAQ

 

Q: what is the solar module?

A: solar panels by cells, components of the border, toughened glass, packaging materials and the junction box and so on, a piece of board can use sunlight to power generation.


Q: what is the solar cell (plate)?

A: solar cell (plate) is a use of solar power photoelectric semiconductor wafer.


Q: types of solar panels?

A: Solar panel common mainly single crystal, polycrystalline,amorphous three materials. Among them, the best single crystal,high efficiency, the price is high; polycrystalline low efficiency of 2%,the price almost, this two kinds of life for more than 25 years;amorphous low efficiency, short life, but the price is cheaper. From the cost point of view, the highest or single crystal.


Q: Standard test conditions of solar cells

A: Power solar panels is in standard condition: temperature of 25 degrees, AM1.5, 1000W/M2 under test. General use WP (WP) said,you can also use the W (W) said. Power test in this standard is called the nominal power.


Q: solar panel is how to work?

A: solar panels can produce current  in a certain intensity ofillumination, the electrical appliance can be used. The premise is the unit of current time than electrical consumption. In practical application, the direct use of the situation is less. Generally the whole system to use.
