From "PV+" to "+PV", the "two-way embrace" of PV and building is achieved
CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. has found its own low-carbon innovative ecological development path.
In April, CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. announced that it would launch a new BIPV solution, including distributed PV roof and PV curtain wall, with four cores of "safety, weather resistance, durability and customization". The roofing system with "super long standby" is selected, with a service life of more than 30 years, meeting the use requirements of PV modules in the whole life cycle.
At present, BIPV is more and more popular, and all major PV companies are preparing for BIPV and launching their own relevant solutions. The reason why the solution of CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. is special is that the innovation of reverse thinking is adopted to realize the pioneering solution of building system in combination with PV design through the construction of industrial ecology.
This is a "two-way embrace" that shows the greatest sincerity between the building industry and the PV industry.
Cross-field temptation and anxiety of carbon neutrality
"Carbon neutrality" is an energy revolution that structurally changes the industrial process and economic structure. Under the tide, every enterprise has a vision for the future, and inevitably faces its own cross-field anxiety.
It has been a very clear general trend for various industries to increase income, reduce emissions or upgrade itself with the help of PV.
However, in practice, although the PV industry is enthusiastic about cross-field expansion, the acceptance of traditional fields is not high. In agriculture, forestry, animal husbandry, fishery and other aspects, PV enterprises often fail to maximize their value due to the lack of integration of technical standards in the two fields or insufficient integration of long industrial chains and production management capabilities, which even evolves into a "zero-sum game", and is particularly prominent in PV agriculture.
All personnel engaged in the PV industry know both significance and difficulty and hardship of PV cross-field.
Around 2009, BIPV took root in China, and a large number of enterprises, research institutions and scholars have taken root in this field for more than ten years. Due to the above reasons, BIPV is still considered to have unlimited potential that has not yet broken out. Many professionals in the building field said that they would like to see the combination of PV and building field, provided that PV products meet the relevant standards of the building industry.
Traditional industries have a complete interest ecological chain, and enterprises, governments and other interested parties lack endogenous power to carry out innovation of models and technologies and integrate and revise standards. Therefore, in order to successfully implement the "PV+" project, PV enterprises often need to run through the whole industrial chain with their own efforts.
However, the demands of building industry for safety, long-term effectiveness and aesthetics often require targeted adjustments to PV products. The transformation cost of a workshop production line may be as high as hundreds or even tens of millions of yuan. If the product R&D from scratch cannot utilize the obtained achievements for continuous R&D, the cost will be hundreds of millions of yuan, with no ceiling.
In addition, the cost of customized modules is too high in terms of production capacity, management cost and auxiliary material price, which will further increase the price of its products in the initial niche market.
CECEP Solar Energy's breakthrough action
As a PV manufacturer, after the national "whole county promotion" policy was promulgated, the Company realized that central and state-owned enterprises had turned their attention to the distributed PV market, and then carried out a series of strengthened design and product innovations according to the actual situation of distributed PV.
In 2021, CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. launched lightweight modules with a weight reduction of 6%-16%, new PV dust collectors and more beautiful color modules for the distributed market, respectively corresponding to the safety (weight reduction ensures roof load-bearing safety and roof installable capacity), operation and maintenance problems and aesthetic requirements of the building when central enterprises enter the distributed market.
CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. New 1.5GW High-efficiency Solar Cell Module Intelligent Manufacturing Project
In 2022, on this basis, CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. took another key step that is considered by the industry as "BIPV ecologicalization":
According to CECEP Solar Energy Technology (ZhenJiang) Co., Ltd., after a multi-party investigation of the steel structure building system, the Butler building system finally became an excellent carrier to carry the PV system of CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. due to its leading maintenance-free full life cycle in the industry. At present, CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. is working with Butler, a global leader in prefabricated steel structure building system, to jointly develop the BIPV system solution, provide PV products compatible with different specifications and technologies, and complete the one-stop overall turnkey solution of project evaluation, design, construction, delivery and operation and maintenance. This solution will separate customers from the tedious engineering process, thus enjoying the benefits of power generation easily. This system solution has been applied to the new 1.5GW high-efficiency solar cell module intelligent manufacturing project of CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. for the first time, and is expected to be put into operation in the third quarter of 2022.
The most noteworthy innovation of this solution is that CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. takes the lead in realizing the "two-way embrace" of PV and building field in the whole industry. In addition to using the new products for PV roofs launched last year in the solution, more importantly, after communicating with the builders, both parties reached a consensus on the prospect of PV roofs. Combined with the product strength of CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. in manufacturing and the investment strength in the project, both parties are determined to improve the traditional metal roof enclosure system and make it more suitable for PV projects, and jointly create a new BIPV ecosystem integrating building materials, PV, operation and maintenance and investment.
"Breakthrough". Huang Guoping, General Manager of CECEP Solar Energy Technology (ZhenJiang) Co., Ltd., expressed the excitement in his heart: "To do a good job in traditional BIPV projects, it is inevitable to use customized solutions with high costs, which is not friendly to the cost-sensitive PV module manufacturing and the pursuit of mass production products. This time, we worked with partners to make innovations in connecting systems and other aspects, and the size of modules is no longer limited." Huang Guoping pointed out that under the tide of global carbon neutrality, the enthusiasm and determination of traditional industries for green transformation have increased unprecedentedly. They have begun to consciously and actively embrace new energy and jointly launch new products suitable for the PV industry with PV enterprises.
The PV roof can be compatible with PV modules of different specifications and technologies, so that the size of modules is no longer limited. In addition, the structural combination of the PV roof is reasonable, there is no hidden danger of water leakage, the roof is maintenance-free, the ability to resist wind and snow is excellent, and the power generation and building functions are integrated. On the premise of meeting high load capacity, the PV modules carried by this product are 13.5% lighter than traditional modules, with four advantages of "light weight, drainage, high load and unlimited size".
In terms of PV curtain wall, PVB adhesive film packaging is adopted to meet the double standards of PV modules and buildings, with the basic characteristics of high conversion efficiency, safety and explosion prevention, and ultra-long service life. This product can be customized in a colorful manner, and can be flexibly switched between unit and structural curtain walls according to the needs of different construction methods.

With the increasing importance of energy conservation and carbon reduction, Butler began to explore intelligent steel solutions, entered the field of green buildings, helped customers in various industries to complete the construction of PV projects in the past 20 years, and completed the first LEED Platinum Certification and three-star green factory project in China in 2012.
In the new BIPV ecology, CECEP Solar Energy Technology (ZhenJiang) Co., Ltd. also plays a flexible and changeable role. It can be either a simple module supplier or a provider of a complete set of solution. When the owner is unwilling to invest in the roof PV system, it can also make investments independently. It is both a partner and an end customer, which is an important reason why construction enterprises are willing to develop new products for this purpose.
More importantly, such a solution is very friendly to the owners. For them, what needs to be selected is only a roof. This "all-inclusive" model in the decoration industry may become the future of BIPV.
