Louvered self-adjusting household photovoltaic system with protective device

Abstract

The invention discloses a louvered self-adjusting household photovoltaic system with a protection device. The louvered self-adjusting household photovoltaic system comprises a louvered photovoltaic panel, a photosensitive sensor, a humidity sensor, a control unit, a driving motor, a transmission device and a shielding curtain. By presetting accurate calculation results of hourly incident angles ofsunlight in all places in a control system, automatic real-time adjustment of the angles of photovoltaic louver blades is achieved, and the sun shading effect and the productivity effect are maximized. Meanwhile, compared with a whole photovoltaic panel, the louver blade design has the advantage that the influence on indoor lighting is reduced. Through simultaneous monitoring of the photosensitive sensor and the humidity sensor, the driving device pulls the shielding curtain to shield the photovoltaic panel in cloudy and rainy days, erosion of rainwater and the like to the photovoltaic panelis avoided, and the service life of the photovoltaic panel is prolonged. Electric energy generated after the photovoltaic panel collects sunlight can charge a storage battery to supply power to the driving motor, the control unit or other direct-current equipment, and can also be converted into alternating current for daily use of a building through the inverter.

Description

Technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a shutter type self-regulating household photovoltaic system with a protective device. Background technique [0002] my country's building energy consumption accounts for 21.11% of the national energy consumption. The heat gain of exterior windows is the main source of building energy consumption, making building shading a hot issue in the field of building energy conservation. The combination of building exterior shading products and solar photovoltaic panels can not only meet the shading demand but also play a role in production capacity. [0003] As a new type of clean energy, solar energy has an important position in the long-term energy strategy. However, the production efficiency of solar photovoltaic panels is seriously affected by the weather. In rainy weather, not only cannot absorb sufficient sunlight, but also affected by rain, which seriously shortens its s...
