Research Rooftop Photovoltaic System And Network

In recent years, by the fossil energy shortages and adverse environment impact, there is increasing attention to environmental protection and green, safe and sustainable energy development. By reducing the burning of fossil fuels, can reduce the pollution of the atmosphere, in order to ensure long-term and stable supply of energy. To solve the problem as soon as possible supply shortage, less electricity area, we should be the implementation of sustainable development strategies to accelerate the development of renewable energy sources, it has become common to seek out solutions. Solar energy resources are very rich, not long exhausted, solar power has many advantages, such as its long life, safe, available everywhere, easy maintenance, no long-distance transmission, less operating costs, no moving parts, no noise, not damaged, no fuel, no pollution. Because protecting the environment gradually attention has been paid, the gradual depletion of fossil fuel reserves and the regular grid problem has some limitations, it is widely believed in renewable energy, solar power is the technical content of the highest and most promising. With the rapid development of photovoltaic industry, the photovoltaic cell production is also rising in unexpected growth, which were used in photovoltaic systems and photovoltaic cells on the Internet accounted for nearly 60%. And rooftop photovoltaic power generation system and network performance in the economic, flexible, etc. are much larger than the grid-connected photovoltaic power plants stronger, but also because of the popularity of convenience, safety and readiness of energy is very beneficial, so get extra attention.PV grid system consists of a solar cell matrix, transformers, grid inverters and metering system components, in addition to these main components, as well as some auxiliary facilities, such as cables, combiner box, protective equipment, switches, lightning protection and so on, through and inverter power delivered to them directly to the public grid and grid-connected inverter also has a maximum power point tracking technology, compared to the overall efficiency and network systems than from high-efficiency network probably about 15%, the same as if the power is given, then the system in terms of cost and net from more than 20% lower than the net, so the PV grid-way will be to guide and promote the development of future PV industry. After photovoltaic power generation system and network design ideas and system configuration in-depth analysis, the future will improve the utilization of solar energy has a positive role in guiding.Through photovoltaic systems theory study and research, mastered the system works, the establishment of a complete photovoltaic system and network system, the paper through statistical analysis of a research project sites sunshine data, estimates of future power plant generating capacity, determined PV module types and models, and the project is expected to refer to the various device parameters such as the capacity to determine the number of major equipment and install a range of issues, through a combination of factors to consider all aspects of proposed PV array design and electrical design of the program.
