[0037] It is known that environmental emission index monitoring is an important link in environmental protection work, aiming to monitor the emission of various pollution sources in real time and accurately through scientific methods and technical means to ensure that it meets national and local environmental protection standards. The following is a detailed analysis of environmental emission index monitoring:

[0038] Monitoring methods and technologies include: field sampling and laboratory analysis: by collecting samples of pollution sources, sending them to the laboratory for chemical analysis to determine the types and concentrations of pollutants. Online monitoring system: using sensors, analyzers and other equipment to monitor pollutants emitted by pollution sources in real time and continuously, and data can be transmitted to the environmental protection department in real time. Remote sensing monitoring technology: using satellite, unmanned aerial vehicle and other remote sensing platforms to monitor and evaluate the environmental pollution situation in a large area.

[0039] Solar power generation is a renewable energy technology that converts solar radiation into electrical energy. It is clean, environmentally friendly, and sustainable. This article introduces the principles, system composition, classification, advantages and disadvantages of solar power generation.

[0040] Solar power generation relies mainly on the photovoltaic effect to convert solar energy into electrical energy. When sunlight hits a photovoltaic cell, photons excite the electrons in the cell, giving them enough energy to jump into the conduction band, thereby forming an electric current. By combining photovoltaic cells into photovoltaic panels, we can get a larger current output and achieve solar power generation. In addition, there is a photothermal power generation method, which uses mirrors or lenses to focus sunlight to produce high temperatures, heat fluids to drive turbines to generate electricity (similar to traditional thermal power generation principles).

[0041] A solar power generation system generally consists of solar cell modules, controllers, batteries, inverters, etc. Among them, solar cell modules and batteries are power systems, and controllers and inverters are control and protection systems.

[0042] Solar cell module: composed of multiple photovoltaic cells in series or parallel, it is the core power generation unit. Commonly used are crystalline silicon cell panels (polycrystalline silicon solar cells, monocrystalline silicon solar cells), amorphous silicon cell panels (thin-film solar cells, organic solar cells).

[0043] Controller: composed of special processors CPU, electronic components, displays, switching power tubes, etc., used to control the charging and discharging process of solar cell modules.

[0044] Battery: stores excess electrical energy to solve the problem of power supply at night or on cloudy days.

[0045] Inverter: converts the direct current (DC) generated by photovoltaic panels into alternating current (AC) for home or grid use. Its efficiency is an important standard when choosing, the higher the efficiency, the less the loss of electricity in the process of converting the direct current generated by the photovoltaic module into alternating current. Solar power generation system is divided into off-grid power generation system, grid-connected power generation system and distributed power generation system: off-grid power generation system: mainly composed of solar cell module, controller, storage battery, such as output power supply for AC 220V or 110V, also need to configure inverter. Grid-connected power generation system: the direct current generated by the solar module is converted into alternating current meeting the requirements of the power grid after passing through the grid-connected inverter and is directly connected to the public power grid. Grid-connected power generation system has centralized large-scale grid-connected power station (generally national power station, the main feature is that the generated power is directly transmitted to the power grid, and the power grid is uniformly distributed to the users, but such power station has large investment, long construction period and large occupation area) and dispersed small-scale grid-connected power generation system (especially photovoltaic building integrated power generation system, which has the advantages of small investment, fast construction, small occupation area and strong policy support, etc., and is the mainstream of grid-connected power generation). Distributed photovoltaic power generation system: basic equipment includes photovoltaic cell module, photovoltaic array support, direct current junction box, direct current distribution cabinet, grid-connected inverter, alternating current distribution cabinet and other equipment, in addition, there are power supply system monitoring device and environmental monitoring device. Its operation mode is that under the condition of solar radiation, the solar cell module array of photovoltaic power generation system converts the solar energy output into electric energy, which is sent into the direct current distribution cabinet through the direct current junction box, and is converted into alternating current by the grid-connected inverter to supply the building itself load, and the excess or insufficient power is adjusted through the connected power grid.
