Gamma in solar photovoltaic power generation system of advantages and disadvantages of is what?

Photovoltaic power generation is the use of solar energy battery components will device for converting solar energy directly into electricity. Solar energy battery components ( 太阳能模块) Is the use of semiconductor materials of P - electronics feature implementation V conversion of a material, in the broad areas without electricity, the device can

photovoltaic power generation is a kind of use solar modules convert solar energy directly into electrical energy device. Solar energy battery components is a use of electronic properties of semiconductor materials to achieve photoelectric conversion material. In the vast areas without electricity, the device can be easily for the user's power supply, lighting and life can also supplement the regional power grid interconnection. Abroad at present, from the Angle of civil, 'BIPV technology is mature in technology research and industrialization, and domestic development and production is mainly used in the electric power in the field of domestic lighting small solar system, large scale photovoltaic (pv) grid technology is started. Advantage ( 1) There is no risk of fatigue; ( 2) Safe and reliable, no noise, no pollution emission, absolute environmental protection, No pollution) ； ( 3) Do not accept the restriction of resource distribution, mounted on building roof has the advantages of beautiful; ( 4) No need for fuel consumption and erection of transmission lines, local power generation and power supply can be realized; ( 5) High quality, Laboratory high conversion rate of 47% or more) ； 6 users in emotional easy to accept, like very much; All landowners construction period is short, short time to obtain energy; Today from the point of view of national security, photovoltaic power generation can be self-sufficient in family, avoid the destruction of the war. Deficiency ( 1) The use of solar energy equipment must have a considerable area. ( 2) The application of solar energy is influenced by climate and day and night. ( 3) Technical limitations lead to low efficiency, high efficiency, low investment of equipment. ( 4) Solar panels, polysilicon production will bring a lot of pollution. Using solar batteries to store electrical energy can cause a lot of pollution.
