Solar panels solar power system is the core part of the solar system, the highest part of the value . Its role is to convert solar energy into electrical energy stored in batteries or sent to , or promote the work load .
When the p -type semiconductor and n -type semiconductor when combined together into a tight , at the interface between the p-n junction is formed . When the cell is irradiated with sun light in the p-n junction is formed on both sides of the positive and negative charge accumulation , the photovoltaic generation of the formation of the internal electric field , which is " photovoltaic effect ." Theoretically, this time, if the electric field on both sides of the built-in and lead-out electrodes connected to an appropriate load , the current will be formed , will be obtained on the load power . The solar cell module is the use of electronics to achieve characteristics of the semiconductor material of solid P-V conversion means . Which is the photovoltaic solar battery works .

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.
