Embodiment

[0064] The present invention will be specifically described below in conjunction with a specific embodiment, but it should be noted that this specific embodiment is only for better describing the present invention, and does not constitute an improper limitation of the present invention.

[0065] Take a rooftop photovoltaic power station as an example. Based on the surrounding air dust pollution and operation and maintenance experience, the cleaning cycle of photovoltaic modules is preset to 30 days.

[0066] First, the power generation data of the standard base station and the reference base station are collected. The first power generation data of the standard base station comes from the manned regional center, and the second power generation data of the reference base station come from the photovoltaic power stations in the area with the same light resources.

[0067] Specifically, the standard base stations arranged in the center of manned areas need to be manually cleaned i...

Abstract

The embodiment of the invention provides a prediction method and a prediction system for cleaning a photovoltaic module. The prediction method comprises the steps that first power generation data and second power generation data of a photovoltaic module are acquired, the first power generation data are the power generation data of the photovoltaic module in a dust-free environment, and the second power generation data are the power generation data of the photovoltaic module in an actual environment; net benefits of the photovoltaic module are calculated in a preset time range according to the first power generation data and the second power generation data; and the cleaning period of the photovoltaic module is determined according to the net benefits of the photovoltaic module. According to the embodiment of the invention, the power generation comparison data of the photovoltaic modules with the same illumination and position can be accurately obtained in real time; and the corresponding net power generation benefit is accurately calculated according to the comparison data, and the monitored power generation operation data of the photovoltaic module is more scientifically calculated, so that the optimal cleaning period for cleaning the photovoltaic module can be accurately determined by utilizing the collected and calculated data.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a prediction method and a prediction system for cleaning photovoltaic modules. Background technique [0002] Photovoltaic modules are installed outdoors, and the fine dust particles and snow accumulated on the surface will affect the light transmittance, which in turn will affect the radiation received by the module surface and affect the power generation efficiency. Partially blocked dirt such as surface soil and bird droppings will cause hot spot effects in local photovoltaic modules, reducing power generation efficiency and even burning the modules. [0003] In order to improve the power generation efficiency of solar panels, it is necessary to clean the solar panels regularly. At present, the photovoltaic operation and maintenance department usually has the following three cleaning strategies for photovoltaic modules: [0004] First, according to the manual pre-establishe...
