At February 25, held on the 27th ~ PVEXPO2009 the second session of the International Solar Exhibition , the solar cell equipment and components has two significant trends, it is fully aware of the solar cell industry in the area of Canton.
Are components of a trend of manufacturers to expand the exhibition area to display for the global business technology. For instance, Asahi Glass display glass plate at the formation of SnO2 on the TCO (transparent conductive oxide) film in kind. Goal is through the use of the membrane surface of the pyramid shaped sealing effect of light conversion efficiency will improve 10 ~ 20 . TCO film CVD process used to install the (offline) method to create form, crystal growth under the conditions at the surface of the pyramid shape on the formation of a variety of changes. Future oriented in the global sales of thin film solar cells.
Kuraray PVB resin exhibited the use of packaging materials. Many solar cells generally used in combination with glass and backplane, using EVA resin package. The PVB resin cola rediffusion achieve through the combination of the use of glass packaging. Because both sides are glass, thereby increasing solar intensity and Weather resistance can be used as skylights and other building materials.
Another trend is EPC (Turnkey) production line, can provide a full set of solar cell production lines have been the emergence of new forces. APEX has provided the United States the use of PST Korea s Equipment full set of the crystallization of silicon production lines. Competitive advantage lies in lower equipment prices. The production of the same scale when comparing the full set of equipment using the German production line required to spend 1.5 billion to 22 billion yen, while the company spent only 10 billion to Ą 1,500,000,000. Solar cell manufacturers Korea has begun to import. In addition, Japan FACILITIES Germany Schmid show the use of company equipment, a full set of production lines, three benefit the semiconductor industry also showed a general contractor approach for the complete set of production lines.

11) Charge mode: constant voltage 4.2V to protect the Lithium battery inside
12) Indication: charging and discharging state
13) Protection: reverse current protection circuit integrated to prevent batteries from being discharged.
Solar cells are made of thin layers of silicon. When sunlight strikes the cells, chemical reactions release electrons, generating electric current. Individual cells are grouped together to form solar modules which, when installed on the roof or ground as a component of a complete solar system, generate electricity.
The components that make up one solar power supply system. Solar power supply system is up of solar panels, solar controller, batteries. If the output is AC 220V or 110V,it need inverter. The action of each part is:
1. Solar Panel: It is the hard core of solar power supply system. Its action is changing radiating power into electric energy or keeping in battery, or driving loads.
2. Solar controller: The action of controller is controlling running order of whole system. It can also avoid battery overcharging or over discharging. In some district, It has the action of temperature correction. Some other additive function such as light control switch, time control. Switch is selectable.
3. Battery: Commonly we use lead acid battery. In micro system we can also use nickel hydrogen battery, nickel cadmium battery or lithium battery. Its action is storing electric energy and releasing when need.
4. Inverter.
Suitable for use in a fixed workplace. Solar panel is separated from solar power, not suitable for working in a removable workplace.
Solar panel is outdoor type. The inverter power box is indoor type.
Can supply appropriative racks for solar panel.
