APPLICATION OF PHOTOVOLTAIC GENERATION
Solar energy is a natural resource. The system collecting and transferring the solar energy, makes it into controllable electricity power, is called solar photovoltaic generation system. This technology was developed in American Bell Laboratory in 1950s and was initially used in space flight area. The global energy crisis in 1970s caused the application in civil areas. After forty years of development, now it forms a set of mature and complete technologies. With the carrying out of global sustainable development strategy, this technology is supported by many governments. It has been popularly applied in developed countries, e.g. America, Europe, Japan, etc and developing countries, like China, India, Brazil, Mexico....

WORKING PRINCIPLE
Solar power system is that the solar panel charges the solar energy after sunshine to transfer into the electric power and store in the battery, though the controller’s over-charging and discharging  protection and inverter"s transformation, supply to electric appliance.
Factors when designing should be considered：
A.The power of the electrical appliance and the working hours.
B.The efficient sunshine hours in the location.
C.The proportion of the rainy and cloudy days in the location.
D.The obligate working hours normally.
E.Set up the data in the light of the weather report for the location of generationing system, such as sunshine hour, natural disaster and so on.
F.The area of the generating system should be wide and secure that there is no high building or other things to cover the solar panels.
G.Nearing the public electric net, better the location of the generating system is.

OFF GRID SOLAR POWER SYSTEM / INDEPENDENT SOLAR GENERATING SYSTEM
When sunlight irradiates on the solar cell assembly, the photovoltaic effect is produced, producing DC Electricity, which, after being adjusted by the controller, is then stored in the storage cell. When the customer needs power supply, the electric power stored in the cell is turned into AC power supply through the controller and inverter. The power from the cell can be supplied for user in household electrical appliances.

SOLAR PANELS GENERATING SYSTEM FOR POWER NETWORK INCORPORATION
Irradiation of sunlight on the solar cell assembly produces electric current, which is turmed into AC power through inverter. Then, AC power electricity is sold to the public electric grid at a higher price. When the user need power supply, the public electric grid will buy in the AC power supply in a lower price to supply the power for user in household electrical appliances.
