In recent years, the photovoltaic industry has become hot.

The reason for this is because the country needs carbon peaks and needs to control carbon emissions.

The energy of sunlight is so abundant that it would be a pity if it is not fully utilized?

Therefore, we can now see a variety of products that utilize solar energy. There are both solar water heater products, solar photovoltaic module products and so on.

When it comes to photovoltaic module products, they are currently mainly divided into three major areas of use, namely household, industrial and commercial.

According to whether the photovoltaic power station is centralized, it can be divided into centralized and distributed.

Compared with the centralized photovoltaic power station that needs to occupy a large area of ground or water surface, the distributed photovoltaic power station can be much more flexible.

Different from the past, the development of distributed photovoltaic power plants is accelerating, and in the long run, the development space of distributed photovoltaic power plants is limitless. After all, less than 10% of vacant places such as roofs are currently being used.

 

01 The combination of photovoltaics and architecture is a major trend

From the perspective of stock, photovoltaic phalanx can only be combined with buildings. Because the building is already done, photovoltaic products can only be fixed to the top or surface of the building. And now it's mostly at the top.

From the perspective of new buildings, the high integration of photovoltaic modules and buildings has more advantages. At this time, photovoltaic modules become part of the building, bringing a complete change to the building.

This integration of photovoltaics and buildings is called BIPV; it includes photovoltaic tile roofs, photovoltaic curtain walls and photovoltaic lighting roofs.

The high integration of photovoltaics and buildings can make the use of photovoltaic products safer and more efficient, and can bring photovoltaic products and buildings into one, adding new functions to buildings.

 

02 The integration of building and photovoltaics usually includes three aspects, namely integrated design, integrated manufacturing and integrated installation.

① Integrated design. The content of the design includes buildings and photovoltaic systems, as well as other required devices and structures, and the walls and roofs of the building are decomposed into structural modules for integration.

②Integrated manufacturing. Establish a special production line, and use this production line to manufacture large-scale, high-efficiency and low-cost manufacturing of designed building structural modules.

③ Integrated installation. The produced structural modules are centrally installed into houses with electric hoisting equipment. Among them, rooftop solar photovoltaic buildings are widely used, and their main features are: the orientation between solar panels and sunlight can be adjusted. my country is located in the northern hemisphere, and the solar panels face south, so the photovoltaic curtain wall has certain limitations.

 

03 The integration of photovoltaic and building brings many advantages

Advantage 1 No additional land occupation

Photovoltaics and buildings are integrated into one, and the surface and top of the building can be fully utilized to achieve the purpose of generating electricity. This saves land resources.

Advantage 2 This is a new type of green energy

The solar photovoltaic building integration generates green energy, and the application of solar power generation will not pollute the environment. Solar energy is clean and free, and there are no ecological side effects in the development and utilization process. It is also a kind of renewable energy, which is inexhaustible and inexhaustible.

Advantage three has a unique architectural beauty

By hiding small parts in the curtain wall structure, the exterior is invisible, and the appearance of the building is not affected at all. And it will present a new architectural aesthetic.

The connecting wires, junction boxes, diodes, etc. used for power generation are hidden to avoid direct sunlight and rain erosion.

Advantage 4 No effect on the lighting of the building

Photovoltaic and building integration have no impact on the original lighting requirements of the building.

If the building has high requirements for lighting, the use of ultra-white double-sided glass components for the arrangement of photovoltaic modules can not only achieve the purpose of enhancing lighting, but also meet the function of photovoltaic power generation.

Advantage 5 Safety performance can be fully satisfied

From the current point of view, BIPV modules can fully meet the power generation performance, and at the same time, in terms of safety, they can also fully meet the safety performance requirements of buildings.

Therefore, photovoltaic and building integration will develop by leaps and bounds because it can not only generate electricity, but also ensure safety.

Advantage 6 Easy installation and long service life

Photovoltaic modules replace ordinary tempered glass, and its structure is basically the same as that of traditional glass curtain walls. This makes the installation of BIPV photovoltaic modules have a profound technical foundation and advantages, and can fully meet the requirements of convenient installation.

Photovoltaic modules are made of PVB material, which can achieve a longer service life. Use special photovoltaic wires, larger wire diameters, and connectors with excellent performance to extend the service life.

 

In terms of building and photovoltaic integration, Sedum Environmental Technology, with its profound technical accumulation in integration and high integration, is making great efforts to explore in depth. The newly launched Guangyao series photovoltaic module products have been widely used in photovoltaic sunrooms. .

I believe that in the near future, we will surely see another excellent brand in BIPV.
