No stopping.
The installation process of the photovoltaic power generation system is complicated and requires high attachments, but the buildings and facilities on which the photovoltaic power station relies should be legal. In order to get better lighting from solar panels, many users have carried out extensive construction work on the roofs of buildings, built photovoltaic cabins, and built brick supports several meters high to store solar panels. The supports are illegal structures, leading to demolition by the urban management department. .
If the installation of photovoltaic power generation systems requires approval from urban management, safety supervision, planning and other departments, photovoltaic systems are still a niche thing in many places, the installed scale is small, and local governments pay little attention to them, making urban management in many places The department has too much room for flexible enforcement in the field of photovoltaic systems.

Notes:
When installing a photovoltaic panel array, you need to consider the installation azimuth and tilt angle. Blockage between the Jiaotong University Blue Sky panels needs to be avoided. Including surrounding buildings (telephone poles, house eaves, etc.).
The stability and firmness of the bracket placement (consider local meteorological data, such as sunshine hours, disaster weather, storms, etc.).
Trace distance and combiner box location. Try to keep trace distances short and even. The terminal blocks must be secure to prevent false connections or disconnections.
The battery terminals must be firm (never short-circuit) and pay attention to the polarity during installation to avoid explosions and fires. The process for applying for national subsidies is as follows:
(1) Residential distributed photovoltaic power generation projects and photovoltaic poverty alleviation projects applying for subsidies must meet the following conditions:
a. Complete the filing in accordance with the procedures.
b. The project has been completed and put into operation, meets the relevant conditions for grid connection, and has completed grid connection acceptance and other grid access work.
(2) Except for photovoltaic poverty alleviation and residential photovoltaics, other photovoltaic power generation projects that require state subsidies:
In principle, they must adopt competitive allocation methods such as bidding and apply through project owners , the competitive ranking method is used to determine the national subsidy projects and subsidy standards. The market competition allocation and subsidy bidding for non-resident distributed photovoltaic projects are implemented under the leadership of the provincial energy authorities. The energy authorities of various cities organize project applications. For specific application conditions and procedures, please refer to the "Guangdong Provincial Energy Administration forwarded the National Energy Administration's 2019 Notice" Notice on Matters Related to the Construction of Wind Power and Photovoltaic Power Generation Projects" (Guangdong New Energy Letter [2019] No. 358) and other relevant documents, or consult the energy authorities.
For projects that meet the conditions for applying for Zaoju Macro, the power supply company will actively assist you in applying for subsidies in accordance with the procedures prescribed by the government. First, it will be submitted to the Ministry of Finance, National Development and Reform Commission, and National Energy Administration after review and approval by the provincial finance, price, and energy authorities. The Ministry of Finance, the National Development and Reform Commission, and the National Energy Administration organize the review of submitted projects, and include qualified projects in the subsidy catalog for announcement. If the project is included in the national subsidy catalog, the state will allocate subsidy funds according to the plan.
Which one is better, photovoltaic power generation or air power generation?
Both photovoltaic and wind power are currently recognized to have a great impact on the environment.Small new clean energy.
However, although it is claimed to be clean energy, strictly speaking, whether it is photovoltaic or wind power, it will have a certain impact on the environment.
For example, photovoltaics will have the following impacts on the environment:
1. The layout of photovoltaic panels will take up a lot of space.
2. During the production process of photovoltaic panels, trichlorosilane and silicon tetrachloride will be produced, which are substances that have an impact on the environment and human health.
For example, wind power will also have an impact on the environment during the deployment process.
It is said that large-scale deployment of wind power will affect atmospheric circulation and cause changes in ambient temperature.
It is also said that large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of rainfall zones.
Leaving aside whether the above statement is accurate, the two new energy sources of photovoltaic and wind power themselves have not yet achieved 100% no impact on the environment. ...it will have some impact to some extent.
Of course, compared with traditional energy sources, photovoltaic and wind power have very little impact on the environment and are environmentally friendly enough. This is why these two new energy sources and other new energy sources have such advantages. extensive development.
Does current photovoltaic and wind power generation require any testing when connected to the grid?
Both wind power and photovoltaic power generation have the common advantages of being clean, renewable, and never exhausted. Wind power generation has more obvious advantages than photovoltaic power generation. Why do you say this? Mainly based on the following two points:
1. The cleanliness of photovoltaic power generation is relative, because the production of solar panels has the characteristics of high pollution and high energy consumption, and the manufacturing process is not environmentally friendly; while the cleanliness of wind power generation Cleanliness is absolute, which has obvious advantages over photovoltaic power generation!
2. After all, the energy distribution density of photovoltaic irradiation is small. To generate a large amount of electric energy, it takes up a huge area. Therefore, solar power stations generally occupy a relatively large area. A 1GW photovoltaic power station requires an area of 300-400 square meters. acres, so photovoltaic power stations are generally built in remote areas with vast land and sparsely populated land and barren land (it is impossible to build photovoltaic power stations on farmland in densely populated areas). Wind energy power generation facilities occupy a small area and have little impact on normal farming of farmland. Especially offshore wind power does not need to occupy land!
Wind power and photovoltaics have obvious seasonality and fluctuation. The proportion of wind power and photovoltaic power generation
It clearly tells you that whether it is photovoltaic or wind power generation, if you want to combine it The power grid must be monitored in accordance with the requirements of the power supply bureau and can be connected to the grid only after meeting the standards of the provincial power grid companies. The specific requirements of each provincial power supply bureau are different. You can consult in detail. In addition, there are national standards for relevant parameters of power quality.
The impact of this proportion is as follows:
1. Wind power is usually stronger in spring and autumn, so the amount of wind power generated in these two seasons will increase. relatively high, while in summer and winter, due to weakened wind power, wind power generation will decrease accordingly; photovoltaic power generation is higher in summer and sunny days, because the sunshine time is long and the intensity of solar radiation is high. In winter and cloudy days, photovoltaic power generation will decrease.
2. The volatility of wind power and photovoltaic power generation is mainly affected by weather conditions, such as changes in wind speed, cloud cover, etc., which will lead to unstable power generation.
