Solar energy lamp posts in parallel grid system

Solar power, away from what is the difference between network and interconnection: off-grid system is refers to, photovoltaic power generation system of electricity stored in the battery, through the inverter to the ac power supply equipment used directly, or without inverter power directly to dc electric equipment

from what is the difference between solar power network and the Internet? Off-grid system refers to the photovoltaic power generation system of electrical energy stored in the battery, through the inverter converts alternating current (ac), gas supply equipment used directly, or do not provide directly by inverter dc electrical equipment, is not connected to the electricity grid. Grid is refers to the photovoltaic convert alternating current by inverter, through the booster or directly access the low voltage side is connected to the electricity grid for dispatching electric power grid. What is the principle of photovoltaic off-grid power generation system? Off-grid photovoltaic power generation system and the working principle of grid photovoltaic power generation systems are very similar. The only difference is, off-grid system power output by the production of road lighting manufacturers direct consumption, rather than the transmission to the public grid used to separate solar power and thermal power generation and photovoltaic power generation. Regardless of the production and sales, development speed and development prospects, photovoltaics are miss photovoltaic power generation. Photovoltaic power generation is likely to be widely used, and less affected by the photovoltaic power generation. Usually, what is called the solar power is often referred to as solar photovoltaic power generation. Photovoltaic power generation is based on the principle of photovoltaic (pv). Li solar cell is used to directly convert solar energy into electrical energy. Either independent or connected to the electricity grid, photovoltaic power generation system is mainly composed of solar panels, Components) Composition. Controller and the inverter is composed of three parts. They are mainly composed of electronic components. They do not involve mechanical parts. As a result, photovoltaic power generation equipment is very delicate, reliable, stable and long service life. It is easy to install and maintain. In theory, photovoltaic power generation technology can be used for any need of power supply. From the spaceship to domestic power supply, from mw power station to the toy. Photovoltaic (pv) power is everywhere. At present, the photovoltaic products are mainly used in three aspects: first, no electric power supply is jointly offered. It is mainly for the majority of residents are without power to provide life and production of electricity. It also includes power microwave relay, etc. In addition, it also includes some mobile power supply and standby power supply. Two solar daily electronic products, such as all kinds of solar charger, solar street light and solar lawn plants in all sorts of lamps and lanterns, etc. The third is connected to the grid. In the developed countries has been widely promotion and implementation. Grid generation has not yet started in China. But, in 2008, Beijing [ Green Olympics quot part of power will be provided by the solar and wind power. Photovoltaic solar cells are the most fundamental component ( ) 。 Have monocrystalline silicon, polycrystalline silicon and amorphous silicon thin film batteries, etc. At present, the largest single crystal and polycrystalline battery usage. Amorphous cell used in some small system and the auxiliary power supply of the calculator. The efficiency of domestic crystal silicon is about 10 - 13%. The efficiency of the same products abroad about 12 - 14%. Consists of one or more of the solar battery of solar panels is called the photovoltaic modules. In 2002, the global production of solar cells and photovoltaic modules which is about 600 mw. Japan accounted for 45%, the United States accounted for 25%, European accounts for about 22%. Japan is the fastest growing of the photovoltaic industry producing. It in less than 10 years than the United States. In 2001, there are four solar battery manufacturers in the world. They are sharp, Kyoto ceramic, sanyo and mitsubishi. Europe and the United States in most developed countries have formulated the 'sunshine project'. And take measures to encourage residents to install solar power generation system. For example, some grants, interest-free loans and [ Seed funding; We will also for the price of several times higher than normal price buy extra solar from people's homes.
