Poly Solar Panel Description

Photovoltaic modules (also called solar panels) are the core part of solar power systems, as well as the most important part of the solar system. Its role is to convert solar energy into electric energy, and sent to stored in batteries, or promote work load.

However, with the use of micro inverter, can be directly convert the current source of pv modules become approximately 40 v voltage source, can drive electrical application in our life.

 

Main Features of Poly Solar Panel

The production process

Step 1 monolithic welding: the battery slice welding interconnection (tin-plate copper belt), to prepare for the series of cell.

Step 2 series welding: the battery in series according to a certain number.

Step 3 laminated: would continue battery series circuit connection, at the same time with glass, EVA film, TPT back to guard the cell.

Step 4 laminated: the battery slice and glass, EVA film, TPT back at a certain temperature, pressure and vacuum conditions binding together.

Step 5 frame: glass with aluminum frame protection, and ease of installation.

Step 6: cleaning to ensure component appearance.The insulation of the

Step 7 performance test: test the component performance and power

Final step packaging warehousing.

FAQ of Poly Solar Panel

Q:About installation cautions?

1 install solar photovoltaic power generation systems requires special skills and knowledge, must be finished by professional engineers.

Q:Requirements of installation personnel?

2 installation personnel to installation, operation and maintenance of photovoltaic components, make sure you fully understand the information in this installation manual, understand the risk of harm could occur during the installation.

Q:What are protective measures?

3 photovoltaic modules under sufficient sunlight or other light source illuminate the production of electricity. When should operate, please take the corresponding protective measures, to avoid people part with 30 v DC or direct contact with the higher voltage.

Q:How does it work?

4 solar photovoltaic modules can converts light energy into direct current (dc), the size of the battery will change as the change of light intensity.5 when components are current or with an external power supply, shall not be connected or disconnected components.

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:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
Q:What is the working principle of solar panels?
the material is easy to industrial production and material performance and stability.
Q:What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q:What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q:Can solar panels be connected directly to motor?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (
Q:What is the principle and structure of solar panels?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
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.
