A photovoltaic power generation greenhouse with adjustable light transmittance

Abstract

The invention discloses a photovoltaic power generation greenhouse capable of adjusting light transmittance. The photovoltaic power generation greenhouse comprises an eastern gable, a western gable, a pair of side walls and a lighting surface skeleton installed on the tops of the eastern gable, western gable and side walls, wherein the bottom of the lighting surface skeleton is provided with a lighting covering film, a movable photovoltaic component and a fixed photovoltaic component are arranged on the top of the lighting surface skeleton in parallel, the movable photovoltaic assembly is moved or fixed relative to the fixed photovoltaic component so as to adjust a transmitting gap between the movable photovoltaic component and the movable photovoltaic component. The photovoltaic greenhouse can initiatively change a coverage rate of the lighting surface photovoltaic component according to different external light conditions and different requirements on the plant growth, so that the photovoltaic greenhouse initiatively controls the lighting rate, the lighting design bottleneck of the existing photovoltaic greenhouse is fundamentally broken through, the maximization of the photovoltaic power generation is realized while the plant production is guaranteed, and the adaptability of the photovoltaic greenhouse to different crops and a same crop at different growth periods is also improved.

Description

technical field [0001] The invention relates to a photovoltaic power generation greenhouse, and more specifically relates to a photovoltaic greenhouse which can adjust the light transmittance of the lighting surface of the greenhouse through its own mechanism. Background technique [0002] In the existing greenhouse construction market, due to the urgent desire to be able to produce crops and at the same time use photovoltaic equipment to generate electricity in production practice, various photovoltaic greenhouses have emerged. These greenhouses have achieved the functions of both production and power generation to a certain extent, which is a good direction for future agricultural development. Especially in places where there is no mains power supply, unstable power supply, and power shortage, it is a good solution. However, due to design flaws, existing photovoltaic greenhouses have to make difficult choices in production practice. One solution is to sacrifice large-area...

Problems solved by technology

[0003] At present, conventional photovoltaic greenhouses use fixed photovoltaic power generation components and fixed angles. Due to defects in architectural design and power generation components, the lighting conditions in photovoltaic greenhouses are not only poor, but also difficult to change and improve once completed.

In recent years, although many researchers have invested a lot of time and energy in studying the relationship between photovoltaic module coverage and power generation efficiency, due to the complexity and particularity of plant lighting problems and the complexity of photovoltaic power generation, this research direction The key to improving indoor lighting in photovoltaic greenhouses has not yet been touched

Moreover, a large number of studies have shown that under the same land construction conditions, the final result of changing the coverage of photovoltaic modules still requires growers to make difficult choices in terms of power generation and production time

Therefore, simply changing the coverage of photovoltaic power generation components cannot fundamentally solve the existing problems of insufficient lighting in photovoltaic greenhouses, and the inability to guarantee production and manufacturing.

[0004] In addition, in the production of photovoltaic greenhouses, due to the greatly improved airtightness of the greenhouse, it is difficult to control the temperature and humidity in the greenhouse. Conventional photovoltaic greenhouses adopt the traditional cooling method of greenhouses, which leads to excessively high indoor temperatures, which in turn affects Normal growth of internal crops

Cannot adapt to internal crop adjustments
