Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0047] Such as figure 1 As shown, a method for calculating the shadow-free time of photovoltaic modules in photovoltaic power generation projects includes the following steps:

[0048] S01, the latitude of a photovoltaic power plant site is φ=31.61°, and the slope angle of the site is b=0°. The photovoltaic modules are arranged in double rows, that is, L=3.32m, the inclination angle of photovoltaic modules is a=26°, and the distance between front and rear rows of modules is d=7.2m.

[0049] Use this calculation method to calculate the time when the photovoltaic modules are not shaded on the winter solstice day (December 21).

[0050] S02, calculate the solar declination angle δ on the winter solsti...

Abstract

The invention discloses a method of calculating the time without shielding of shadow for a photovoltaic assembly for a photovoltaic power generation project. For the method of calculating the time without shielding of shadow for a photovoltaic assembly for a photovoltaic power generation project, after knowing about the parameters, such as the latitude of the location of a photovoltaic power station, the length of a battery assembly, the separation distance of the battery assembly, the inclination angle of the battery assembly, and the mountainous region gradient inclination angle, the time without shielding of shadow for a photovoltaic assembly can be acquired under the layout scheme condition. The method of calculating the time without shielding of shadow for a photovoltaic assembly for a photovoltaic power generation project has the advantages of being accurate in calculation, being able to provide important parameters for comprehensive analysis of the photovoltaic power generation project, effectively analyzing various economic parameters, and solving the problem that in the prior art, the practical time without shielding of shadow for the photovoltaic assembly cannot be calculated.

Description

technical field [0001] The invention provides a method for calculating the shadow-free time of a photovoltaic module in a photovoltaic power generation project, which belongs to the technical field of photovoltaic power generation engineering. Background technique [0002] With the continuous expansion of the global economy, human demand for energy continues to grow. At present, the energy consumed by humans mainly comes from fossil fuels such as coal, oil, and natural gas, which are non-renewable energy sources. The depletion of conventional energy has led to increasingly prominent environmental problems, which in turn lead to regional environmental pollution and large-scale ecological damage, specifically manifested in the greenhouse effect, ozone layer destruction, global climate change, acid rain, species extinction, land desertification, and sharp decline in forests. , transboundary pollution, marine pollution, reduction of wild species, reduction of tropical rainfores...
