Abstract

The invention discloses a dust-fall testing device and an experimental method for measuring the influence of an accumulated dust on a power generation efficiency. The dust- fall testing device comprises a blower device, a small hourglass device, an angle adjustable baffle device, and a photovoltaic panel support. The small hourglass device comprises a funnel support and a funnel arranged at the upper part of the funnel support, wherein a vertical pipeline is arranged at the bottom of the funnel. The blower device comprises a blower support, a blower arranged on the air blower support, and an air outlet pipe connected to the air outlet of the blower, wherein the air outlet pipe is communicated with the vertical pipeline. The photovoltaic panel support comprises a support base, a photovoltaic panel frame, and support legs, and support legs are movably connected to the back surface of the photovoltaic panel frame, and the support base is connected to the photovoltaic panel frame through asupport rotating shaft. The dust-fall testing device can simulate the accumulated dust on the surface of the photovoltaic panel under the testing conditions of different photovoltaic plate angles anddifferent blowing time, and can simulate the settlement and the accumulation of the dust on the surface of the photovoltaic panel well.

Description

technical field [0001] The invention belongs to the technical field of test devices for photovoltaic power generation equipment, and in particular relates to a dust fall test device and an experimental method for measuring and calculating the influence of dust accumulation on power generation efficiency. Background technique [0002] With its rich solar energy resources, Northwest my country has become an important new energy application base and a concentration area of ​​solar photovoltaic power generation projects in my country. It has gathered more than 90% of China's wind power projects and solar photovoltaic power generation projects, and has a high location advantage. Although the northwest region is rich in solar energy resources, most of the region is located in desert or sandy land. Due to the particularity of the geographical location, environmental problems are prominent. At the same time, the windy climate also makes it easy to accumulate more dust in the northwes...
