Solar photovoltaic power generation the main advantage of is what?

The solar cell can be set up on the roof at ordinary times unused space, such as no noise, long service life, and once set up, almost don't need to be adjusted. Now, as long as on the roof with solar cells could be self-sufficient in home electricity. Today

solar battery can be installed in a room not commonly used, such as roof, no noise, long service life, almost no adjustment after installation. Now, as long as the roof with solar cells, and family can be self-sufficient. Today, the main use of solar energy is no longer a small, but is dedicated to the nature. It in the field of military, communication, and play an important role in urban construction area. Venezuela also introduced a cheap solar car, European scientists have developed can wear in the body of the portable solar battery. At present, there have been great development, the use of solar energy related technologies possible breakthrough in a short time. It is in many developed countries as an important part of the energy strategy. Solar photovoltaic power generation system is a kind of use solar photovoltaic effect of semiconductor materials will direct solar radiation energy into electrical energy new power generation system. It has run independently and parallel operation of two modes. In order to fully effective use of photovoltaic solar energy, how to choose the azimuth Angle and tilt Angle of photovoltaic solar energy is a very important problem. Photovoltaic solar azimuth Angle is the Angle between the vertical plane and south square. In general, when square facing south, the output power of solar cell is very large. When it deviates from the south ( In the northern hemisphere) 30 degrees, the phalanx of generating capacity will be reduced about 10% ~ 15%; When it deviates from the south ( In the northern hemisphere) 60 degrees, the square of the output will be reduced about 20% ~ 30%. However, in the sunny summer day, the sun radiation energy is important moment in the late afternoon. Therefore, when photovoltaic solar slightly tilt to the west, you can gain a lot of power in the afternoon. In different season, when the direction of the solar photovoltaic power generation slightly or east to west, will have power. Only when the Angle is right, the function of solar panels can be fully used, and generate a lot of energy. It not only protect the environment and nonrenewable resources, but also for life and production. Choosing a good Angle using photovoltaic solar panels.
