Agricultural photovoltaic complementation

Application introduction

The implementation of agricultural photovoltaic complementation mainly involves the following aspects:
1. Photovoltaic panel layout: When arranging photovoltaic power generation panels in farmland, it is usually by erecting brackets or installing special solar panels so that they will not affect the normal growth of crops and farmers' operations when they are at a certain height above the ground.
2. Reasonable layout: In agricultural photovoltaic complementation, the layout of photovoltaic panels needs to be considered to ensure that light energy reaches crops evenly and does not affect the ventilation and lighting between crops.
3. Crop selection: Choose crops suitable for symbiosis with photovoltaic panels. Some dwarf crops that do not require high-intensity light, such as tea, grapes, vegetables, etc., are usually more suitable to be combined with photovoltaic panels.
4. Light transmittance: The design of photovoltaic panels must consider transmittance, that is, ensuring that enough sunlight passes through the photovoltaic panels to reach the crops to maintain their normal growth.
5. Comprehensive utilization of resources: Using open farmland to arrange photovoltaic panels can make use of abandoned land. At the same time, crops can also play windproof, thermal insulation and other functions.
6. Economic benefits: Agricultural and photovoltaic complementation can achieve dual benefits of agriculture and energy, and improve the comprehensive benefits of farmland. Solar power can bring additional income to farmers without severely affecting crop yields and quality of farmland.

Application parameters

Practical application

For large-scale grid-connected power generation projects that combine solar energy with modern agriculture, in addition to self-use, the remainder is integrated into the national grid. Generally, photovoltaic agricultural projects install power generation panels on the roof of greenhouses and use photovoltaic power generation panels to generate electricity. It makes full use of the idle space on the roof of the agricultural greenhouse, and can also provide the electricity needed for automatic watering, lighting, ventilation and heating in the shed.

The roof of the shed generates electricity and edible fungi, blueberries, flowers, fruits, etc. are grown under the shed. The implementation of this project will not only increase farmers' income and accelerate the pace of agricultural industrial structure adjustment, but also effectively solve the bottleneck problem of land acquisition for the development of photovoltaic projects. Plants with different light requirements can be configured according to different lighting conditions on the sunny side and the shady side to comprehensively improve land utilization; higher greenhouses can build three-dimensional agriculture and use LEDs for supplementary light. For example, when raising seedlings, the seedlings can be Bed frame etc. In a certain land space, photovoltaic agricultural greenhouses achieve a "win-win" between agricultural crop economics and energy generation benefits.
