Mr Zhu is not the first to make such a suggestion. Last year, Yu Xiaogang, a citizen, asked the Shanghai Municipal People's Office to put forward proposals to improve the installation standards of household photovoltaic camping solar panels power generation facilities.
He found that the installation of photovoltaic panels often caused neighborhood disputes due to the impact of lighting and glare. And the photovoltaic panels have different shapes and are uneven, which also destroys the overall appearance of the community. Residents complained to the urban management and law enforcement departments and demanded that the buildings be demolished as illegal. However, according to the relevant regulations of urban management, photovoltaic panels belong to equipment and facilities, do not belong to construction (structure) buildings, can not be classified as illegal buildings, and therefore can not be dismantled according to illegal construction (structure) buildings, and mediation has little effect.
He mentioned that on May 1, 2017, the former Municipal Bureau of Quality and Technical Supervision issued the "Service Specification for distributed photovoltaic power generation projects", in terms of specific installation, only 4.32 mentioned that "When service enterprises implement distributed photovoltaic projects on buildings, they shall not reduce the sunshine standard of adjacent buildings, and there shall be no glare." As for the installation of specific requirements and installation standards are not mentioned, there is no clear law enforcement authorities and law enforcement basis for relevant disputes.
The installation specifications of photovoltaic power generation facilities are indeed improving step by step. The reporter noted in the call of 12345 citizen service hotline that the staff of the Nanxiang business station of the State Grid Shanghai Jiading Power Supply Company had replied to the residents to apply for photovoltaic power generation equipment, and it is necessary to provide identity documents, housing title certificates, bank cards, if the house is a townhouse, it is also necessary to provide the proof materials that the neighbors agree to install and the property agrees to install the license certificate. After the materials are ready, you can apply for the application at the counter of the power company network or the App of the National network on the Internet.
On March 1 this year, the "Technical Standards for the application of solar photovoltaic power generation in Buildings" was officially implemented. Professor Shen Wenzhong of Shanghai Jiao Tong University, one of the editor-in-chief units of relevant technical standards, said that photovoltaic technology has entered the popularization and application stage from demonstration projects for more than ten years, and in the process of preparing standards, it has been targeted at photovoltaic panel installation problems that residents are concerned about, and some operating specifications have been indexed to deal with, and strive to meet the needs of residents for power generation and reduce neighborhood problems. Gong Chunjing, deputy chief engineer of Shanghai Electric Power Design Institute Co., Ltd. further added that after technical demonstration, whether it is single row or side by side laying, the height of 1.5 meters is enough to meet the required inclination Angle of panel power generation, and can limit the possibility of illegal construction under the panel. In theory, if strictly implemented in accordance with technical standards, the probability of affecting lighting between buildings is very low.
Peng Shenghuan, executive deputy secretary general of the Shanghai Solar Energy Society, one of the participants, said, "People usually regard photovoltaic panels as electrical facilities like solar water heaters, thinking that after the installation of electricity, you can leave it alone. The Standard puts forward a series of requirements for the layout, construction and inspection of photovoltaic panels, such as the whole process inspection after installation, and the certificate of conformity and the instruction manual should be submitted to the user after acceptance. For example, the selection of inverter of core parts is required to have the function of preventing DC arc pulling and automatic shutdown. If the surface of the building where the installation facility is installed uses combustible materials such as asphalt and polyester fiber, a fire protection layer shall be laid.
In view of the installation status of Xinting community in Lishui, the above experts believe that it is not recommended to forcibly install photovoltaic panels by raising the bracket on the north slope. On the one hand, the "Standard" stipulates the installation of the downslope surface, and the installation of the non-downslope surface cannot meet the requirements of the current technical standards. On the other hand, the non-slope installation faces the north wind, the support has a large force, and the corresponding fixing requirements are very high, which brings great hidden dangers to the building structure. In the case of non-standard treatment, it is very likely to be overturned by strong winds.
But the question is, how does the professional advice provided by the Standard translate into constraints on the installation of solar photovoltaic panels? How to deal with existing photovoltaic panels installed in violation of the "Standard"?
