Prospects For Building Integration Of Photovoltaics
With the continuous improvement of environmental protection consciousness, the low-carbon concept has penetrated into all aspects of life. Building Integrated Photovoltaics(BIPV), is the perfect combination of Double-low-carbon in the field of energy and construction.
Building Integrated Photovoltaics(BIPV) is a form of utilizing solar energy and an application form of distributed photovoltaic power generation system. BIPV project is an organic combination of photovoltaic power generation modules and buildings, which has both power generation function and building material properties.
A good BIPV project should meet the following conditions.
1.Core Photovoltaic Technology
In BIPV project, photovoltaic modules are building materials that provide photovoltaic power generation capacity, and their power generation capacity is a key indicator for judging the pros and cons of products. Therefor, a good BIPV project is inseparable from advanced technical support.
2.Good Fire Resistance
Since the PV modules may be shaded, the shaded PV modules will consume the energy generated by other PV modules as loads, resulting in a hot-spot effect. Local high temperature is easy to break down the back sheet, resulting in a fire. Additionally, any loose joints in a BIPV system can create a DC arc, which can easily lead to component burnout and a fire. As a part of building, BIPV project should have good fire resistance.
3.Excellent Waterproof Performance
The integration of photovoltaics and buildings has extremely high requirements on the waterproof performance, especially in areas with high precipitation and frequent heavy rainfall. Therefor, the quality of photovoltaic modules and the proper installation method are very important.
4.Easy To Clean And Maintain
Photovoltaic modules are different from ordinary building materials because photovoltaic modules may cause loss of power generation and power attenuation after accumulating dust. Dust on modules can also affect the exterior image of the building. Building integration of photovoltaics should take long-term cleaning and maintenance issues into account.
5.The Product Has Good Heat Dissipation
The characteristics of photovoltaic power generation cause it to generate heat during the power generation process, which affects the power generation efficiency of photovoltaic modules. If the heat generated when the product generates electricity cannot be dissipated in time, it will be further transmitted to the lower buildings, and it will be further transmitted to the lower buildings, resulting in an increase of the temperature in the building and further increase in the energy consumption required for cooling the building. Therefore, a good BIPV project should have a special ventilation and heat dissipation design.
6.Meet The Aesthetic Requirements
BIPV architecture is not just a building, it is the work of the architect. We need to think from a global perspective, how to combine modules and buildings efficiently and organically. What kind of design can meet the aesthetic requirements while maximizing the power generation efficiency of the modules.
The BIPV project is one of the solutions for the continuous development of new energy, promoting urban energy conservation and emission reduction, and improving the quality of human life. It is a global development trend to promote buildings towards near-zero energy consumption. In the future, we will see more photovoltaic and building integration masterpieces such as photovoltaic curtain walls, photovoltaic roofs, photovoltaic windows, and photovoltaic complex buildings.
Empower buildings, make cities more beautiful, and make life better.
