In today's world, coal, petroleum and other fossil energy dries up, the problem of the environmental pollution is more and more serious. And solar energy as a potential renewable energy, because of its reserves of unlimited, the universality of existence, the use of clean and practical efficiency, the
in the world today, fossil fuels such as coal and oil are often in a state of emergency, the pollution of the environment problem is becoming more and more serious. Solar energy as a kind of potential renewable energy, because of its reserves of infinite, clean and widespread utilization and practical economy more and more get the favour of people. Positive development of the rapid development of photovoltaic industry and solar before empty has won the world's attention, and has become an important part of national sustainable development strategy. Photovoltaic industry, also known as the solar cell industry, which USES solar energy level semiconductor electronic devices to absorb solar radiation energy and convert it into electricity. Photovoltaic power generation monitoring system can real-time monitoring battery arrays of solar photovoltaic power station, the mother box, inverter, ac/DC power distribution cabinet, solar tracking control system, etc. Through various types of charts and data, can quickly grasp the power plant operation. Its friendly user interface, powerful analysis function and improve the fault alarm to ensure that the completely reliable and stable operation of solar photovoltaic power generation system. Our solar photovoltaic power generation system has a wide application in particular, because the new technology has just developed, and it is a very flourishing period. We in many countries are using the new technology, in many areas is using the technology. Then let's look at our application field of photovoltaic power generation systems. As far as I know, of an office building in mumbai, India, the new technology has been applied. Its name is judah office building. It adopts the design of solar energy, is passive. It can be our light intensity to regulate the temperature of the our office building itself. By reducing the income, the people who live in the interior can feel the warm winter and cool in summer. Therefore, the building became very famous. Another country is fribourg solar city. The city was called this name, because the roof of the residential building design adopted here our photovoltaic panels, generally equivalent to form a awnings on the roof, also can have the effect of warm in winter and cool in summer. In addition, as a matter of fact, many foreign cities have adopted the new technology, it is associated with photovoltaic power generation systems. Second, they are all the application areas of photovoltaic power generation systems, including solar power all-in-one PC applications, such as many of our family of solar garden light, solar home system, relatively independent power supply system for small villages, and the water pump, also like photovoltaic panels, drinking water and irrigation of crops. These are all our family or light industrial use, can also be used in communication systems, such as road signs.
