Solar photovoltaic power generation, green and environmental protection, make your life full of sunshine

Description	Photovoltaic power generation has significant energy, environmental protection and economic benefits, and is one of the best green energy sources. Solar energy resources are extremely rich, widely distributed and easy to apply. Vigorously developing new strategic renewable energy industries including photovoltaic power generation, accelerating the adjustment of energy structure, and establishing an "independent, self-reliant, clean and sustainable" energy system are the fundamental way out for my country to deal with the dual problems of fossil energy shortage and air pollution. 1. The photovoltaic power generation process does not emit greenhouse gases, other waste gas and waste water. Photovoltaic power is truly environmentally friendly green power. US National Renewable Energy Laboratory NREL is based on a full life cycle CO2 emission study of 13 different types of polysilicon photovoltaic systems (manufactured in Europe 2005-2006), at a solar radiation of 1700 kWh/m2 per year, the system life Under the condition of 25-30 years, the module efficiency is 13.2%-14.0%, and the system power generation efficiency is 75%-80%, the average value of carbon dioxide generated per kWh of electricity in the entire life cycle of the polysilicon photovoltaic system is 45%. The average value of carbon dioxide produced per kWh of electricity in the entire life cycle of coal-based thermal power generation is 1,000 grams. According to the statistics of the World Wildlife Fund (WWF), under the average sunshine conditions in my country, installing a 1-kilowatt photovoltaic power generation system can generate 1,200 kWh of electricity in one year, which can reduce the consumption of coal (standard coal) by about 400 kilograms and reduce carbon dioxide emissions. About 1 ton, to put it figuratively, installing 1 square meter of solar photovoltaic modules is equivalent to afforestation of 100 square meters. 2. The operation of photovoltaic power generation system does not require fuel and water. The solar photovoltaic power generation system can be used as long as it can get sunlight. It is not restricted by factors such as altitude and region, and has a wide range of applications. 3. The construction, operation and maintenance of photovoltaic power generation system are easy to operate The solar cell module is simple in structure, small in size and light in weight, easy to transport; easy to construct, install, disassemble and migrate; it can be installed modularly according to different system capacities, and the photovoltaic power generation system has no mechanical rotating parts and will not generate noise. More importantly, operation and maintenance become simple, and the stability and reliability of system operation are improved. With the development of automatic control technology, the photovoltaic power generation system can realize unattended operation, and the operation and maintenance cost is greatly reduced. 4. The photovoltaic power generation system has stable, reliable performance and long service life At present, it is generally believed that the life of crystalline silicon photovoltaic modules is 25-30 years. The 25-year lifespan of the modules mentioned here refers to the power warranty period of the modules, that is, the power of the modules after 25 years is not less than 80% of the initial power, and does not mean that the modules do not generate electricity at all or rarely generate electricity. In fact, the efficiency decline of photovoltaic modules is a slow process, so photovoltaic modules can continue to provide clean electricity for human beings for 30 years or even longer. 5. Photovoltaic power generation brings positive energy to the improvement of local microclimate environment In the process of its own power generation, the photovoltaic power generation system will not only have no adverse impact on the surrounding environment, but also improve the local microclimate environment. The covering of photovoltaic modules keeps the temperature of the shallow soil in the photovoltaic power station stable and is lower than the soil temperature outside the electric field, which reduces the evaporation of soil moisture, increases the soil moisture, and reduces the temperature difference between day and night near the surface air. The combination of temperature and humidity conditions helps the soil to conserve water and nourish microorganisms and vegetation, and play a positive role in improving the local ecological environment of photovoltaic power plants.
