China involves the use of solar energy as energy source, solar cell for photoelectric conversion, and battery to provide energy after storage. The off-grid and independent lighting devices have the following standards that have been issued or are being approved (in order of time):
1. National standard GB/T 19064-2003 Technical conditions and test methods for household solar photovoltaic power systems.
2. Local standard DB11/T 5422008 Technical requirements for solar photovoltaic outdoor lighting.
3. National standard GB/T- solar photovoltaic lighting device general technical specifications (to be approved).
4. Industry standard NY/- Technical requirements for rural solar photovoltaic outdoor lighting installations (pending);
NY/- Rural solar photovoltaic outdoor lighting installation specifications (pending).
The following is a brief introduction to several standards.
First, the national standard GB/T 19064-2003 domestic solar photovoltaic power system technical conditions and test methods
In remote mountainous areas and pastoral areas, there is a lack of electricity for household use and lighting, and photovoltaic power supply systems developed to improve the living standards of people in these areas. It is suitable for small-scale photovoltaic power generation systems that use solar energy to solve household electricity and lighting in the pastoral and mountainous areas.
This standard has been applied for many years, and its contents are familiar to you and will not be described.
The charge and discharge controller is one of the important components of solar photovoltaic lighting devices.
In the national standard GB/T 19064-2003, the technical requirements (6.3.1 to 6.3.13) and test methods (8.2.1 to 8.2.12) of the charge and discharge controller are specified. The other three standards are based on this, only the ambient temperature range of the charge and discharge controller, the test method (6.3.1 and 8.2.1 of GB/T 19064-2000), according to the ambient temperature range of the actual application of the device Modifications, other terms (6.3.2 to 6.3.13 and 8.2.1 to 8.2.12 of GB/T 19064-2000) are directly cited in the other three standards.
Second, Beijing local standard DB11/T 5422008 solar photovoltaic outdoor lighting device technical requirements
According to the historical task and construction opinions of the central government on the construction of a new socialist countryside, Beijing has implemented a project to brighten the countryside in the rural areas of Beijing in 2006. By the end of 2007, 823 villages, which accounted for 20.7% of the total number of villages, installed nearly 100,000 solar photovoltaic outdoor lighting devices such as solar-powered village street lights and rural tourist road lights. It has effectively improved rural living conditions and protected the environment, and has been well received by farmers. Since the solar photovoltaic outdoor lighting device is a new product, the outdoor use environment is relatively harsh, and there is a lack of uniform standards, resulting in a total failure rate of up to about 10%.
The Beijing Municipal Science and Technology Commission, the Agriculture Committee and the Quality Supervision Bureau approved the proposal for the establishment of local standards for the technical requirements for solar photovoltaic outdoor lighting devices proposed by the Beijing Lighting Society in March 2007. The technical requirements for solar photovoltaic outdoor lighting devices were announced on March 28, 2008 and implemented on May 1, 2008. The standard number is: DB11/T 5422008; record number.
DB11/T 5422008 solar photovoltaic outdoor lighting device technical requirements main content:
1 Scope
Applicable to rural, township, public places and pedestrian road lighting in Beijing, combining solar cell components, batteries, lighting components, controllers and mechanical structures, with solar energy as energy, off-grid and independent outdoors Lighting device used. The device is aimed at functional lighting in rural areas and does not involve decorative lighting.
2, configuration and classification
a) The technical content of the device involves multiple professions, and the components are divided into five parts according to the profession;
Solar photoelectric conversion component (solar battery component);
Energy storage component (battery);
Control unit (charge and discharge controller and transmission line);
Lighting components (electric light sources and their accessories and lamps);
Structural components (light pole, solar cell assembly holder, battery compartment and controller room, etc.).
b) Two categories are used according to their purpose in order to facilitate the formulation of corresponding technical requirements:
Garden lights for outdoor public places, courtyards, residential areas, leisure areas and sidewalks;
Street lamps for road lighting such as township streets and rural tourist areas where motor vehicles are used.
