National standard for photovoltaic modules

[Standard number] GB/T9535-1998

[Standard name] Design and identification of crystalline silicon photovoltaic modules for ground use

[Implementation time] 1999-06-01

[Standard content]

This standard specifies the requirements for the design, identification, and finalization of crystalline silicon photovoltaic modules for use on the ground. This module is used for a long period of time under the general outdoor climate conditions defined in GB/T4797.1. This standard applies only to crystalline silicon components. Criteria for membrane components and other environmental conditions such as ocean or equatorial environmental conditions are under consideration. This standard does not apply to components with a condenser. The purpose of this test procedure is to determine the electrical and thermal properties of the module at the most reasonable cost and time, indicating that the module can be used for a long period of time under the specified climatic conditions. The actual life expectancy of components passing this test will depend on the design of the components and the environment and conditions they use.

5 System configuration, technical characteristics and basic requirements for installation

5.1 Solar cell array

5.1.1 Solar cell array consists of one or more solar modules. If there is more than one component, the current and voltage of the component should be basically the same to reduce the loss of series and parallel combination.

5.1.2 Determine the total power of the solar array based on the local solar radiation parameters and load characteristics; determine the number of components of the parallel array of solar arrays according to the voltage and current requirements of the designed system.

5.1.3 Solar cell array supports are used to support solar modules. The structural design of the solar cell array should ensure that the connection between the module and the holder is firm and reliable, and the solar cell module can be easily replaced. Solar cell arrays and supports must be able to withstand winds of 120km/h without being damaged.

5.1.4 Brackets may be adjustable in inclination or fixed at a fixed angle so that the solar cell array can produce the maximum amount of electricity in the design month (ie, the month with the worst average daily radiation).

5.1.5 The fasteners of all square arrays must have sufficient strength to reliably hold the solar cell module on the square array support. Solar arrays can be installed on rooftops, but the array support must be connected to the main structure of the building and not to the roofing material.

5.1.6 For ground-mounted solar cell arrays, the minimum spacing between solar modules and the ground should be 0.3m or more. The bottom of the column must be firmly attached to the foundation so that it can withstand the weight of the solar array and can withstand the design wind speed.

5.1.7 For portable low-power power supplies, solar panels should have brackets for reliable placement.

5.2 Battery

5.2.1 The battery pack may consist of one or more batteries in series and no more than 4 batteries in parallel. Types of batteries suitable for use in the system include deep-cycle lead-acid batteries, sealed lead-acid batteries, common-open lead-acid batteries, and alkaline cadmium-nickel secondary batteries.

5.2.2 Deep-cycle lead-acid batteries are the preferred products for home solar photovoltaic power systems.

5.2.3 Design the minimum capacity of the battery according to the local continuous rain and rain conditions. The design depth of discharge (DOD) of the deep-cycle lead-acid battery is 80%, and the design depth of discharge (DOD) of the shallow-cycle lead-acid battery is 50%.
