Q:What is the principle of solar panels work?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on. This is the photoelectric effect of the working principle of solar cells.
Q:Can cold light make solar panels power
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:What is the difference between solar panels and light panels?
The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.
Q:The voltage and power problems of solar panels
3, charge 12V battery when the power is really small, if it is a normal controller, then the equivalent of 18V voltage in the charge, probably 18 x (240 / 30.2) = 143w solar panels.
Q:What is the principle and structure of solar panels?
Solar power generation system consists of solar cells, solar controllers, batteries (group) composition. If the output power is AC 220V or 110V, also need to configure the inverter. The role of each part is
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:What is the working principle of solar panels?
the material is easy to industrial production and material performance and stability.
Q:Composition and function of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
