Industry Information Zero Carbon Technology: Ultra-light solar panels bring innovation to building photovoltaic integration.

Release Time:


In recent years, under the blessing of various characteristics such as double carbon, double control of energy consumption, promotion of the whole county and return of investment value, the application scenarios of distributed photovoltaic are becoming more and more extensive, starting from residential roofs and industrial plants to gradually enter schools, hospitals, transportation, agricultural facilities and so on.


Roof load bringsNew issues


A variety of application scenarios also means a variety of roof structures, and the load conditions of different roof structures are not the same, so we should pay special attention to the load problem of distributed photovoltaic roof to avoid serious safety accidents.


Roof collapse is essentially a problem of roof load capacity sensitivity, and this problem is also one of the risks that distributed photovoltaics need to pay special attention.


In the grid roof or weak color steel plate roof to do photovoltaic must pay attention to the load sensitivity of different structural forms, to choose carefully. According to public information, stadiums, convention and exhibition centers, cultural facilities, clubs, warehouses and other similar scenes mostly use grid structure, so the development of distributed photovoltaic in the above scenes must do a good job of effective load report.


Especially when adding photovoltaic equipment on the roof of existing buildings and structures, we must be alert to the load changes that the installation of photovoltaic modules may bring to the roof of the building. Once the load exceeds the original design value or the distribution situation changes significantly, it may lead to structural damage, and even the serious consequences of the overall collapse.



The mayor of Bilbao, Spain, blamed the recent collapse of the roof of a local sports center on heavy rain and the presence of a large number of solar panels, local news media reported. The solar panels were installed after Inbisa Construcci obtained the project in 2010. The project originally consisted of 120 solar panels, but based on photos of the collapse, there are an estimated 168 solar panels. The company's total investment in the project is € 411,000 ($440,797).


China's industrial and commercial building roof resources are very rich, under the guidance of policy, roof photovoltaic is becoming the main force of clean energy. However, in the natural environment where extreme climates are becoming more frequent, the service life of the color steel tiles is about 7 to 8 years in need of maintenance, and 10 to 15 years in need of replacement, which does not match the average 25-year service life of the photovoltaic power plant. For photovoltaic investors, this means that the photovoltaic power plant needs to be dismantled and replaced two to three times in 25 years. In this process, not only part of the power generation revenue is lost, but also the component life is affected and the installation cost is increased.


On the other hand, the roof structure of some buildings is complex and there is no large flat space, which also limits the installation of solar photovoltaic panels.


Extreme weather poses a major challenge to building photovoltaics


From 8: 00 a.m. to 9: 00 a.m. on Saturday, April 20, 2024, a storm suddenly fell in tengxian county. the ceiling iron sheets and photovoltaic panels of a ceramic enterprise building in tengxian zhonghe ceramic park and the ceiling iron sheets of a ceramic enterprise building were all violently attacked by the cyclone and were blown down onto the hillsides and roads outside the factory, causing huge losses.


In the early morning of March 31, strong winds, thunder, lightning and heavy rainfall occurred in Nanchang City, Jiangxi Province. The strong convective weather has caused 4 deaths and more than 10 injuries in Nanchang. According to the monitoring of Nanchang meteorological station, on the evening of March 30, 79 of the 103 wind stations in the city had a maximum wind speed of more than 7, 58 stations had a maximum wind speed of more than 8, 37 stations had a maximum wind speed of more than 9, 22 stations had a maximum wind speed of more than 10, and 7 stations had a maximum wind speed of more than 11. One station monitored gale force winds of over 12.


The photovoltaic power station on the roof of the residential area was not spared, and was blown over by the strong wind. At the same time, the strong storm weather also let Jiangxi many photovoltaic power plants suffered a serious impact. According to the netizen for the map can be seen, the roof photovoltaic photovoltaic power station was overturned, the damaged area is larger.‍‍‍‍‍‍


Extreme weather occurs frequently. In the process of construction and application of building photovoltaic, it is often faced with severe climate and environmental tests. It should be standardized and guided from the aspects of design and installation standards, and from the aspects of project site selection, product selection, design and construction, so as to minimize the risk caused by extreme weather.



Active Surfaces Corporation



In the United States, startup Active Surfaces has introduced low-cost, flexible, and lightweight solar panels that enable them to be installed in many new locations. The company is a subsidiary of the Massachusetts Institute of Technology, and the panel design is based on 10 years of research. Active Surfaces's solar material is thinner than human hair, and it is so flexible that solar panels can be installed on almost any surface.


The company's panels are 120 times lighter than traditional panels and reduce structural costs by 90%. Active Surface focuses on dual-use spaces rather than disposable solar farms that require large tracts of land. The flexibility and ultra-light weight of the company's panels allow it to be used in relatively small and oddly shaped spaces, from balconies and old roofs to public buildings and transportation. There are many such spaces in the city.


Another transformative aspect of Active Surfaces technology is the company's focus on economic accessibility. By virtue of obtaining a special. With its rapid manufacturing technology and lightweight packaging, the company makes cost savings that benefit end users as well. In addition, less heavy equipment is required to move the panel into place and fix it, thereby further reducing installation costs while shortening the time required to complete the project.


Active Surfaces will use breakthroughs in industrial roll-to-roll semiconductor printing technology to expand its laboratory-manufactured 4 × 4 inch photovoltaic equipment to enable mass production of thin flexible solar materials of any size.


Active Surfaces, an innovative flexible solar panel startup spun off from MIT, has raised $5.6 million in an oversubscribed pre-seed funding round in May. This round of financing is led by Safar Partners, a well-known deep technology venture capital fund.


British Solivus Company



In the UK, lightweight solar experts Solivus using innovative, flexible solar panels to bring renewable energy to 40% of commercial rooftops and large buildings that cannot afford the weight of conventional solar.



The company provides innovative panels for commercial buildings, which can be installed in stadiums, schools and airports. Each installation is customized according to the position, size and orientation of the building relative to the sun, ensuring that each structure can support the maximum number of panels.


Free of rare earth materials and using organic solar panels, Arc is a beacon of innovation and expertise for Solivus in the field of lightweight solar energy. Solivus also stressed that Arc's manufacturing costs are very low.


Solivus also provide engineering, design, installation, monitoring, and maintenance reports so that customers can understand how much money they have saved or made from solar energy.
