Embodiment Construction

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.

[0034] The invention provides a method for calibrating the illumination direction of a light source. Calibration methods include:

[0035] Step S1: divide the target irradiation area into at least two areas to be tested;

[0036] Step S2: Turn on the light source and measure the light intensity value of each area to be tested;

[0037] Step S3: Determine the adjustment angle of the light source according to the light intensity value;

[0038] Step S4: Adjust the illumination direction of the light source according to the adjustment angle.

[0039] Preferably, the area of ​​each area to be tested is equal.

[0040] When using the calibration method of the present invention, the light source of the solar simulator should be placed in the dark box first, ...

Abstract

The invention provides a calibration method of a light source irradiation direction. The calibration method comprises the following steps of: S1: dividing a target irradiation region into at least two regions to be measured; S2: turning on a light source and measuring the illumination intensity value of each region to be measured; S3: confirming the adjustment angle of the light source according to the illumination intensity value; and S4. adjusting the irradiation direction of the light source according to the adjustment angle. The irradiation direction of the light source can not be calibrated only with the experience by workers any longer, so that the calibration precision of the light source irradiation direction can be improved, the difference intensity of the illumination intensity value within the target irritation region can be reduced, and the accuracy of the output power of a solar module obtained by test can be improved. Meanwhile, the calibration accuracy of the output power of the solar module obtained is improved, so that the economic loss of enterprises can be avoided, and the economic benefit can be improved.

Description

Technical field [0001] The present invention relates to the field of solar machinery, and more specifically, to a method for calibrating the direction of light source irradiation. Background technique [0002] As the energy crisis becomes increasingly prominent, solar power generation has become one of the main means for the development and utilization of new energy. Because solar energy is non-polluting, non-regional, and inexhaustible, solar power is widely used in all aspects of human production and life. [0003] Photovoltaic power generation through crystalline silicon solar cells is a major way of using solar energy today. After crystalline silicon wafers are prepared into solar cells (ie, crystalline silicon solar cells), multiple solar cells are connected in series and parallel, and then glass substrates, ethylene-vinyl acetate copolymer (EVA) and metal frames are used to connect in series Good battery strings are packaged and protected to form solar battery modules with ...
