Photovoltaic power generation and adjustable external sunshade integrated system on building facade

Abstract

The invention discloses an integrated system of photovoltaic power generation and adjustable external sunshade of a building external wall. The system comprises sun shields movably arranged at the outer side of the building, PVB film located in the middle and two tempered glass clamped at the inner side and the outer side of the PVB film, wherein the sun shields are made of photovoltaic tempered laminated glass, and one of the tempered glass is photovoltaic tempered glass; the system further comprises supporting standing rods capable of moving vertically, a rod pushing motor used for driving the supporting standing rods to move vertically is fixedly arranged on the building, a photovoltaic wire connected with the photovoltaic tempered glass is arranged inside each supporting standing rod, one side edge of the photovoltaic tempered laminated glass is hinged to the corresponding supporting standing rod, the middle of the photovoltaic tempered laminated glass is hinged to the building through a rotating shaft arranged horizontally, so that when the rod pushing motor drives the supporting standing rods to move vertically, the photovoltaic tempered laminated glass moves around the rotating shaft in a turnover mode. The system has a photovoltaic power generation function and is capable of preventing the sunlight from illuminating into a room directly, the amount of solar radiation in the room is reduced, and meanwhile indoor lighting quantity can be adjusted according to the indoor lighting conditions.

Description

Technical field [0001] The invention relates to an integrated system of photovoltaic power generation and adjustable external shading on a building facade. Background technique [0002] Solar energy is an inexhaustible clean and renewable energy. It is one of the most promising energy sources that mankind can expect. The sun is radiating a lot of light and heat to the earth's surface at all times, which can be used by humans. Solar photovoltaic power generation is one of the commonly used forms of renewable energy utilization in current construction projects. However, some construction projects cannot use photovoltaic power generation systems in a large area due to their own site restrictions. The facade of a building can also be used as a place for installing photovoltaic panels, but there are two problems: 1) The photovoltaic panels installed on the facade have low photovoltaic power generation efficiency due to the small angle with the sun; 2) the installation of photovoltaic...

Solar photovoltaic power generation is one of the commonly used forms of renewable energy utilization in current construction projects. However, some construction projects cannot use photovoltaic power generation systems in large areas due to their own site constraints.

The building facade can also be used as a place for installing photovoltaic panels, but there are two problems: 1) The photovoltaic panels installed on the facade have a small angle with the sun's rays, and the efficiency of photovoltaic power generation is low; 2) Installing photovoltaic panels on the facade It may block the light from entering the room, affect the natural lighting of the room, increase the power consumption of lighting, and may not achieve the effect of energy saving
