72 Cells Mono Pv Module / Anodized Aluminum Frame Photovoltaic Solar Panels



Whats the solar energy:

The single solar battery can not be used directly as a power supply. For power supply, several single battery strings, parallel connections, and tight packages must be packaged into components. Solar cell components(also known as solar panels, photovoltaic components) are the core part of solar power generation systems and the most important part of solar power generation systems. Its role is to convert solar energy into electrical energy, or send it to storage in a battery, or promote load work. The quality and cost of the solar cell assembly will directly determine the quality and cost of the entire system.

The Feature of the solar panels:

It has high photoelectric conversion efficiency and high reliability. Advanced diffusion technology ensures the uniformity of conversion efficiency in all parts of the film; Ensure good electrical conductivity, reliable adhesion and good electrode weldability; High-precision screen printing graphics and high flatness make the battery easy to automatically weld and laser cutting.

Transparent battery assembly
1 laminator component generation
2 Aluminum alloy protective laminate, plays a certain role in sealing and supporting
3, The junction box protects the entire power generation system and acts as a current transfer station. If the component is short-circuited, the junction box automatically disconnects the short-circuit battery string to prevent the entire system from being burned. The most important thing in the junction box is the selection of diodes. According to the type of battery chip in the component, the corresponding diodes are also different.
4 Silicone sealant, used to seal the junction of components and aluminum alloy borders, components and junction boxes Some companies use double-sided rubber strips and foam cotton to replace silicone. China's domestic use of Silicon gel is simple, convenient, easy to operate, and The cost is very low.

Is solar power difficult to use?
Although the production of solar panels incorporates a high-tech manufacturing process, it is really very easy to use a photovoltaic system. Solar panels have no moving parts to wear out, they can be used alone or in combination with other energy sources, and they are silent, reliable and long lasting.

What can you power with Photovoltaics?
A properly designed photovoltaic system can supply electricity for many applications, from small remote lighting needs to megawatts of power for large utility companies. An advantage of photovoltaic power is that it can do anything a traditional power generator can do, only without consuming pollution-causing fuel, or requiring noisy motors.

What is a PV system?
A PV system consists of all the equipment and materials needed to generate solar energy, including solar panels (often called modules), a support structure, wiring, an inverter, a meter and other equipment as required by a specific application. Longsun Solar’ s PV system for commercial buildings, and ET Solar system for residential uses are examples of complete PV systems.

What is a solar module?
Solar modules are series of solar cells, wired together and enclosed protect them from the environment. They are often referred to as in self-contained glass units to solar panels as well.

How do solar cells work?
Solar cells are solid-state devices in which photons (or packets of light) collide with atoms. This process transforms the resulting into electrons. These electrons flow into wires connected to the cell, thus providing electric current to appliances, lighting systems or other electrical loads; and all of the power comes directly from the sun.

What is Photovoltaic Power?
Photovoltaic (PV) power is a term used to describe the process of converting sunlight into electricity with solar cells. These cells are specially constructed from semiconductor materials, and are treated to generate a flow of electricity when sunlight shines on them.
