01 Introducing industries to the local area and integrating development based on project resources

(1) Agricultural and photovoltaic complementary construction model

Combining solar photovoltaic power generation with agricultural planting, pollution-free, zero emission, and no additional land occupation.

Its mode is photovoltaic power generation outside the greenhouse, planting vegetables inside the greenhouse, which can achieve three-dimensional value-added utilization of land.

(2) Forestry Photovoltaics Complementary Construction Model

Forest Photovoltaics complementarity is a unique afforestation model that fully utilizes the sufficient space between photovoltaic panels and the ground with a height difference of more than 2 meters, vigorously develops economic shrub planting, and organically combines photovoltaic power generation with forestry development, which can achieve three-dimensional value-added utilization of land.

(3) The complementary construction model of Fishery Photovoltaics

Starting from the demand for complementary Fishery and Photovoltaics, the project sets up a photovoltaic panel array above the water surface of the fish pond.

The water below the photovoltaic panel can be used for fish and shrimp farming, and the photovoltaic array can also provide good shading for fish farming, forming a new power generation model of “upper power generation, lower fish farming”.

(4) The complementary construction model of Livestock Photovoltaic

Starting from the needs of animal husbandry, the project aims to naturally cultivate and reuse renewable energy. The upper level is engaged in photovoltaic power generation, while the lower level is engaged in animal husbandry. Photovoltaic conversion power generation is applied to the construction of breeding and ranching, achieving three-dimensional value-added land utilization and building a modern and efficient agricultural comprehensive economy.

02 Utilizing existing abandoned mining areas for land restoration and reuse

(1) Design scheme for combining “irrigation+grass” and wind and sand prevention and control

Adopting a combination of surface planting “irrigation+grass” mode according to local conditions for wind and sand prevention and control measures, and constructing a surface vegetation protection system, the prevention and control measures adopted include: setting up shrub plant sand fixation grids in the project area, planting sand plants, etc.

(2) Special design scheme for wind and sand prevention and control

Fixed angle bracket under photovoltaic panels in the project area – sand fixation between panels: This area is all fixed angle brackets, and grass squares are set between panels to plant herbaceous vegetation under the fixed angle bracket area.

(3) Photovoltaic+land restoration and governance

Flexible supports and large-span slope support technology can be used, which can adapt to different slope directions and terrains, and can be used for large-span tension crossing gullies.

Not only can it effectively reduce the overall construction cost of the project, improve safety and durability, and resist strong wind damage, but also in areas with the same land area, the construction capacity is about three times that of conventional fixed supports, greatly improving land utilization efficiency.

03 Multiple complementary abilities, learning from each other’s strengths and weaknesses

(1) Combined with incremental distribution network pilot projects

Incremental distribution network business and electricity sales business can establish a correlation between the production, transmission, and consumption of energy in multi energy complementary systems, thereby achieving multi energy complementary optimization.

Multi energy complementarity is carried out in incremental distribution networks, which can achieve integrated optimization of multi energy complementarity systems on a large scale. It is a key development model to be considered in large-scale multi energy complementarity projects.

(2) Combined with pilot projects for distributed generation trading

This mode is actually consistent with the principle of the combination mode of incremental distribution network, which is to establish a coupling relationship between multi energy complementary systems and users through market transactions within the distribution network, and then achieve optimization of multi energy complementary systems.

(3) “Internet plus” smart energy

On the one hand, we will integrate multiple energy generation technologies, increase research and development efforts on key technologies and specialized technologies for wind, solar, hydro, thermal, and multi energy complementary storage, as well as key equipment such as multi energy complementary controllers;

On the other hand, building a good experimental platform to provide platform support for the reliability verification of these technologies, equipment, and systems.

(4) Multi energy complementary park

The comprehensive smart energy project of the multi energy complementary park takes the park as a unit, takes the natural gas distributed energy station as the core, integrates distributed photovoltaic, distributed wind power, demand side response and other auxiliary energy supply and consumption systems, realizes the multi energy complementation on the energy supply side and the integration of energy consumption terminals, makes full use of advanced energy Internet, big data and other information technologies, realizes the intelligent management of regional energy supply and demand, builds a new energy supply and consumption ecological chain, and meets the requirements of green, low-carbon, safe, efficient and sustainable development.

04 Flexibility and application value based on photovoltaic module structure and layout

(1) Integrated photovoltaic building (BIPV, BAPV)

Photovoltaic building integration can be divided into two categories in the industry. One is BAPV, which attaches photovoltaic systems to buildings, and the building roof and photovoltaic system form their respective systems, with physical integration between the two;

Another type is BIPV, which integrates solar photovoltaic power generation products into buildings and can replace existing roofs as building materials, such as daylighting roofs, photovoltaic curtain walls, photovoltaic tile roofs, and photovoltaic module roofs, all of which belong to building material photovoltaic systems.

(2) Photovoltaic+Transportation (toll booths, service areas, etc.)

With the development of technology, the application scenarios of photovoltaic+are becoming increasingly diverse, and it can be seen that photovoltaic+is applied in high-speed rail, ordinary rail, high-speed service areas, car sheds, parking lots, and other areas.

The construction of green transportation infrastructure, combined with the supply of clean new energy such as new energy vehicles and charging piles, is an important measure to support the optimization of transportation energy, increase the proportion of renewable energy, effectively promote green electricity to transportation, and promote the low-carbon development of the transportation industry.
