Embodiment Construction

[0053] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0054] The method for calculating the power generation performance of a double-sided battery module using a multi-irradiation sensor of the present invention is performed according to the following steps:

[0055] In the field of photovoltaics, a radiometer is generally used to measure solar radiation, but the backplane radiation is unevenly distributed and difficult to measure. This invention proposes a method for linearly calculating radiation. Such as figure 1 As shown, the specific method is as follows:

[0056] Because the frontal irradiation is easy to measure and relatively uniform, the frontal irradiation of the present invention adopts 2 radiometers to collect data and take the average value; the backboard adopts 4 or more radiom...

Abstract

The invention discloses a method for testing power generation performance of double-sided solar battery components by using multiple irradiation sensors. The method comprises the following steps: acquiring back irradiation data of a component; calculating linear irradiation in a certain position on a back plate of a battery piece; solving low-irradiation current distributed in different positionsby using a relation between irradiation and current; solving generated power of the back plate according to a mismatch model; calculating power gain of a double-sided battery; and calculating energy output of the double-sided battery. Through the method, the linear formula is firstly used for calculating the irradiation of the back plate and relatively accurately calculating a series of parameterssuch as irradiation amount, current in different positions of the back plate and the power generation amount of the back plate and the like; the method is of great significance to the deep study on the performance of the double-sided batteries.

Description

technical field [0001] The invention discloses a method for calculating the power generation performance of a double-sided battery assembly by using a multi-irradiation sensor, and belongs to the technical field of photovoltaic power generation. Background technique [0002] In recent years, the solar photovoltaic industry has developed rapidly, and the actual power generation performance of photovoltaic modules has also attracted much attention. In practical applications, single-sided modules cannot make full use of light energy, and the efficiency is often low. Compared with traditional single-sided modules, double-sided photovoltaic modules use the scattered and reflected radiation from the back of the module, which has higher power generation efficiency. However, the existing design of photovoltaic power plants is based on single-sided modules, and there are few related applications of double-sided modules at home and abroad. Contents of the invention [0003] The te...
