With the rapid development of science and technology and the popularization of environmental protection concepts, the construction industry is experiencing an unprecedented green revolution. With its unique charm and potential, photovoltaic building integration technology is rapidly emerging as a new trend leading this revolution. It not only changes our traditional understanding of architecture, but also creates a greener and more sustainable future for us.     1. Photovoltaic building integration: concept and basic principles   Photovoltaic building integration, referred to as BIPV, is an innovative model that combines photovoltaic power generation technology with architectural design, construction and operation. It uses photovoltaic panels as part of the building materials and directly integrates them into the exterior walls, roofs or windows of the building to achieve efficient energy utilization and green buildings. The emergence of this technology not only improves the energy efficiency of buildings, but also gives buildings new aesthetic value.   2. The perfect integration of green energy and architectural aesthetics   One of the biggest features of photovoltaic building integration is that it can perfectly integrate green energy with architectural aesthetics. Traditional photovoltaic panels are often regarded as cold and monotonous industrial products, which are difficult to coordinate with diverse architectural styles. However, with the continuous advancement of photovoltaic technology, modern photovoltaic panels can already achieve diversified appearance designs. They can present different colors, textures and shapes, and can even imitate the appearance and texture of traditional building materials. This enables photovoltaic panels to better integrate into the overall style of the building, achieving the harmonious unity of green energy and architectural aesthetics.   3. The dual boost of cost reduction and policy promotion   The popularization of photovoltaic building integration also benefits from the continuous reduction of costs and the strong promotion of policies. With the improvement of the photovoltaic industry chain and the expansion of production scale, the manufacturing cost of photovoltaic panels has decreased year by year, making its application in the construction field more economical and feasible. At the same time, governments of various countries are also actively introducing relevant policies to encourage and support the development of photovoltaic building integration. These policies include tax incentives, subsidy support, loan discounts, etc., which provide strong policy guarantees for the promotion of photovoltaic building integration.   4. Technological innovation leads the rapid development of the industry   Technological innovation is one of the key factors in promoting the development of photovoltaic building integration. In recent years, many innovative achievements have emerged in the field of photovoltaic technology, providing strong technical support for photovoltaic building integration. For example, new photovoltaic materials have higher photoelectric conversion efficiency and longer service life; intelligent control systems can realize automatic adjustment and optimized operation of photovoltaic systems; wireless transmission and Internet of Things technologies make the monitoring and management of photovoltaic systems more convenient and efficient. The application of these new technologies not only enhances the performance and quality of photovoltaic building integration systems, but also reduces maintenance costs and usage complexity.   5. Application Cases and Broad Prospects   The application of photovoltaic building integration has spread all over the world, involving commercial buildings, residential buildings, public facilities and other fields. In the field of commercial buildings, photovoltaic building integration provides clean energy supply for shopping malls, office buildings, etc., reduces operating costs and enhances corporate image. In the residential field, solar building integration provides residents with a reliable source of electricity, reduces dependence on traditional power grids, and reduces electricity bills. In the field of public facilities, photovoltaic building integration provides sustainable energy solutions for parks, schools, etc., and contributes to the green development of cities.   With the continuous advancement of technology and the continuous expansion of the market, the application prospects of photovoltaic building integration will be broader. In the future, we can foresee that more buildings will adopt photovoltaic building integration technology to achieve energy self-sufficiency and environmental sustainable development. At the same time, with the further innovation and improvement of photovoltaic technology, the performance and quality of photovoltaic building integration will be further improved, creating a more comfortable, convenient and environmentally friendly living and working environment for people.   6. Industry Challenges and Future Development   Although solar building integration has shown great potential and broad prospects, we also need to seriously deal with the challenges it faces. Unified technical standards, professional installation and maintenance, and the popularity of market awareness are all factors that limit its further development. Therefore, we need to strengthen technical research and development, improve relevant standards, improve installation and maintenance levels, and strengthen publicity and education to improve the public's awareness and acceptance of photovoltaic building integration.   In the future, with the continuous breakthrough of technology and the gradual maturity of the market, photovoltaic building integration is expected to occupy a more important position in the field of construction. It is not only a key component of the green transformation of the construction industry, but also an important driving force for promoting human society to move towards sustainable development. We have reason to believe that in the near future, photovoltaic building integration will become the mainstream trend in the construction field, creating a greener and better future for us.   In short, photovoltaic building integration, as a new trend in the future construction field, is leading the green transformation of the construction industry with its unique advantages. Let us join hands to jointly promote the popularization and development of photovoltaic building integration and embrace a greener and better future.

The integration of solar energy with architectural design has paved the way for innovative solutions such as building-integrated photovoltaics (BIPV). This technology not only makes the use of renewable energy possible, but also enhances the aesthetics of modern architecture. In this detailed blog, we will explore the concept, benefits, applications, and the future of sustainable building design of building-integrated photovoltaics (BIPV).     How BIPV Works: Technology Overview The PV module is the basic component of building-integrated photovoltaics (BIPV) technology. The module consists of solar cells that are connected together to form an array customized for a specific site. PV systems capture the sun's energy and convert it into heat and electricity. The electricity generated by PV panels can power direct current (DC) appliances or can be stored in batteries.   The output of the PV system can be connected to an inverter or converted to alternating current (AC) power for other applications or fed into the utility grid. Balance of system (BOS) refers to the additional components of a building-integrated photovoltaic (BIPV) system, including inverters, switches, controllers, meters, power conditioning equipment, wiring, support structures, and energy storage components.   Types of BIPV Systems PV Roof Systems The use of PV panels in roof systems can be a direct replacement for batten-seam metal roofs, traditional three-tab asphalt shingles, and ceramic tiles. Note that this type of installation requires adequate ventilation to keep the cell temperatures low.   BIPV Curtain Walls Solar cells can supplement or replace traditional French windows or laminated glass. While these modules are mounted on vertical surfaces, which reduces the intensity of solar radiation, the overall size of the curtain wall helps to make up for the reduced power per unit area.   BIPV Skylights The use of PV panels in skylight systems can save on the cost of PV panels and can be an interesting design feature. Like PV windows, translucent structures can both create a visual connection to the exterior environment and provide diffuse natural light.   BIPV Awnings PV modules can be integrated into awnings or slightly angled sawtooth canopy designs. Translucent modules can filter sunlight from below while providing additional architectural benefits such as passive shading.

베트남 정부청은 최근 2024년 7월 30일자 공지 번호 356/TB-VPCP를 발행하여 자체 생산 및 생산을 위한 인센티브 메커니즘과 정책을 규정하는 법령의 제정 및 공포에 대한 Tran Hong Ha 부총리의 결론을 요약했습니다. 자기 개발.     옥상태양에너지 자체생산 개발을 위한 법령 제정 및 타당성 확보   이번 발표는 자체 생산 옥상 태양에너지 개발을 장려하기 위한 메커니즘과 정책 수립이 재생에너지 개발을 촉진하고 국민의 경제적 기대를 충족시키기 위해 사회적 자원을 동원하는 매우 중요한 정책임을 확인시켜준다.   법령의 발전을 가속화하기 위해 법령이 발행 및 시행될 때 품질, 타당성, 적용 가능성 및 효율성을 보장하고, 절대로 허점을 남기지 않고, 정책 허점을 이용하지 않으며, 기회 제공 메커니즘을 만들도록 Tran 부총리는 말했습니다. 홍하는 산업통상부에 '자체생산·자체이용' 개념 개선을 제안했다. 옥상 태양 에너지; 전력판매 비중을 높이고, 자가생산과 자가사용의 의미를 명확히 한다. 태양광 발전. 그 중 발전량은 전체 용량의 90%를 차지하며, 국가 전력망에 판매되는 비율은 10%를 초과하지 않습니다.   동시에, 각 지역의 특성, 실제 전력 공급 상황 및 전력 공급 구조에 따라 태양광 발전을 장려하고 동원하기 위한 상응하는 정책을 수립합니다.   이를 바탕으로 우리는 합리적이고 과학적인 근거를 연구 및 계산하고, 전력망에 대한 잉여 전력의 비율을 규제하며, 북부 지역이 총 용량의 20% 비율로 전력망에 액세스할 수 있도록 허용합니다. 중부 및 남부 지역은 총 용량의 10%를 그리드에 판매할 수 있습니다. 북부 지역 태양광 루프탑의 전압 용량 구조는 다른 지역보다 우선적으로 고려되어야 한다고 판단된다(북부 지역의 동원률은 여전히 낮고, 높은 부하를 더 높은 비율로 동원할 수 있기 때문).

미국 청정에너지 컨설팅업체인 Clean Energy Associates(CEA)에 따르면 유럽은 2024년 첫 4개월 동안 중국에서 약 33GW의 태양광 PV 모듈을 수입했는데, 이는 중국 전체 모듈 수출의 43%에 해당한다.   PV 공급, 기술 및 정책 보고서(2024년 2분기)에서는 유럽과 미국의 공급 및 정책 시장 환경, 글로벌 실리콘 공급망 및 기술 동향을 조사합니다.     유럽의 수입 통계는 "수입품과 경쟁할 수 없기 때문에 많은 장기 공급업체가 생산을 중단하거나 파산 신청을 함에 따라 유럽의 PV 공급이 줄어들고 있다"는 CEA의 관찰과 일치합니다.   셀 등의 기업과 모듈 제조업체 Meyer Burger는 노르웨이 잉곳 생산업체인 NorSun과 폴리실리콘 생산업체 REC는 지속 불가능한 시장 상황으로 인해 지난 12개월 동안 유럽 공장을 모두 중단하거나 포기했습니다.   CEA는 또한 약 600GW의 새로운 폴리실리콘 생산 능력에 더해 올해 글로벌 모듈 및 셀 생산 능력이 매년 300GW 이상 증가할 것이라고 밝혔습니다. 글로벌 용량은 이미 수요를 훨씬 초과했으며 BNEF(Bloomberg New Energy Finance)의 1월 보고서에 따르면 새로운 용량은 없다고 밝혔습니다. 태양광 용량 10년 말까지 글로벌 목표를 달성하려면 필요합니다.
