Technical and economic analysis of domestic BIPV photovoltaic building materials integrated system in 2021 under the background of building

Lifting Anchor

In the process of calculating the yield of the whole system, We need to consider the marginal rate of return at all levels in multiple dimensions.

This is also an inevitable process or phenomenon in the early stage of the development of this industry.

For some application scenarios, BIPV is from the perspective of architecture and on the premise of ensuring the functional requirements of the building system, On the one hand, the investment of BIPV building system can reduce the static investment of capex of the building system itself.

BIPV, the gas station with the highest coverage rate, in fact, most photovoltaic enterprises at home and abroad do not have the concept and experience of building system, so they rely on professional construction engineering companies or traditional building materials manufacturers, For its products (photovoltaic modules or components) to provide supporting building materials for easy installation.

What is BIPV? We believe that power generation products with building attributes and building functions can be called BIPV, and any mode relying on additional building materials or building materials with additional photovoltaic panels can only be called bapv.

The success of this model is a great test of whether the two enterprises can reflect their advantages from the aspects of architecture, safety and economy based on the first principle, Whether it can create greater value for customers.

BIPV building under construction # in addition to the traditional power generation function, At the same time, it shall also have [wind pressure resistance], [water tightness], [waterproof performance], [air tightness], [sound insulation performance] [thermal insulation and sunshade performance] and other necessary performance and unique decorative functions of building envelope, so as to achieve the perfect combination of building envelope, building energy conservation, solar energy utilization and building decoration.


Serial No.: description of manufacturer’s product features: inverter selection and DC side voltage level 1tesla-bipv sub Watt, with building functions and properties, BIPV micro series inverter + shut-off, 200V DC 2 Helio Helios power generation building materials, with complete building functions and properties, instead of building surface materials, BIPV special micro inverter, 48V and 80V.

Longyan BIPV curtain wall glass, with architectural function, BIPV series inverter, 1000v4 Trina Solar tile standardized module + mortise and tenon structure, improved bapv series inverter, 1000v5 GCL gangzhijie BIPV standardized module + self-adhesive and clamp installation, improved bapv series inverter, 1000v6 Jingke BIPV double glass module + silica gel and clamp installation, improved bapv series inverter, 1000v7 Longji Longding BIPV double glass module + silica gel bonding installation, improved bapv centralized or series inverter, 1000v8 shangmai BIPV light module + adhesive installation, improved bapv series inverter, 1000v9 one light module + adhesive installation, improved bapv series inverter, 1000v10 CITIC Bo conventional module + guide tank support, Centralized or series inverter with building fire risk, 1000V academician Tao of Xi’an Jiaotong University, President Wang Shuguo of Xi’an Jiaotong University, former counsellor Shi Dinghuan of the State Council served as the leading project manager of Tongchuan national photovoltaic power generation technology in 2019, and Datong Longji Leye module factory presided over the preparatory period..

Looking at BIPV buildings, it is precisely because photovoltaic enterprises do not have the ability to solve building systems, they have to give full play to their expertise to do a good job of photovoltaic panels.

BIPV near zero carbon building} from the perspective of the construction industry, who can meet the basic lines and elements of power generation buildings, capacity buildings and future buildings can be closer to the needs of customers.

Extended reading of my family’s distributed photovoltaic project: 2021 domestic BIPV photovoltaic building materials integration technology & Economic Analysis under the background of building carbon neutralization (1) Technical & Economic Analysis of 2021 domestic BIPV photovoltaic building materials integrated system under the background of building carbon neutralization (2) technical & Economic Analysis of 2021 domestic BIPV photovoltaic building materials integrated system under the background of safe building carbon neutralization (3) Driven by the national policy: the Ministry of housing and urban rural development will take the calculation of building carbon emissions as a mandatory requirement.

Based on this definition, BIPV is essentially a building surface material with photovoltaic power generation function, which can be directly used A system solution for building surface use, rather than a simple photovoltaic module concept.

The properties and building functions of the building still rely on these traditional building materials, and the photovoltaic module components are simply attached to them and only serve as power generation devices.

Please pay attention to the large-scale park level BIPV cowshed implemented by Helios in Ningxia.

In the next issue, I will make a detailed analysis on the technical and economic evaluation of various BIPV projects.

This series of analysis will focus on the indicators of Helios Helio, zhongxinbo, Trina Solar, GCL, Jingke, shangmai, Longding, Tesla and daycare BIPV products one by one; Hope to provide reference for investors.

Of course, not all the products of the above manufacturers can save CAPEX and OPEX.

At the same time, because of the incremental advantages of the system in waterproof, anti-corrosion and fire prevention, OPEX can significantly save the operating expenses incurred by the original building maintenance and repair in the service life of the building.

Of course, the success of the company is a systematic project, including a comprehensive competition of capital, marketing, resources, technology and talents.

Because Therefore, in the past period of time, a large number of photovoltaic enterprises have emerged to bind a construction company to promote BIPV.
