A globally renowned health and hygiene products company has been actively advancing green manufacturing and low-carbon operations in recent years. At its Beijing production base, a rooftop PV power plant has been installed to optimize the factory’s energy structure with clean energy, further integrating sustainability into its production and operational processes. While strengthening its core business, the company continues to drive its green transformation by replacing traditional energy with solar power, reinforcing the foundation of sustainable manufacturing and embedding green development principles into every aspect of its operations.
The project was invested in and developed by BECIS, a provider of integrated distributed energy solutions. Headquartered in Singapore and backed by leading international shareholders such as Siemens and FMO, BECIS is a professional energy investor operating across eight Asian countries, with strong capabilities in delivering stable and reliable energy services. Throughout the project implementation, BECIS placed strong emphasis on technical excellence and digitalization to ensure optimal system performance from day one. Under the professional execution of the BECIS team, the project was successfully completed and grid-connected in just 44 days. This collaboration highlights BECIS’s strengths in capital and technical expertise, and stands as a best-practice example of high-quality project delivery jointly achieved by BECIS, the project owner, and AndSolar, all committed to excellence.
Unlike conventional rooftop PV systems, this project adopts a herringbone (A-frame) array design, where each row forms two surfaces with different orientations. This layout enables the system to simultaneously capture sunlight from two directions on the same rooftop. As a result, power generation performance tends to show segmented differences across areas. However, under traditional inverter- or string-level monitoring, these differences are often difficult to visually identify, posing challenges for O&M teams.
To improve plant safety, visualization, and operational efficiency, the Beijing PV project introduced the module-level precise management solution from AndSolar. The plant has a total installed capacity of 800 kW, equipped with 648 smart shutdown devices and 4 gateways, laying the foundation for module-level monitoring.
Through AndCloud 3.0, the power generation performance of each individual module can be viewed and compared at the component level. The platform reconstructs the power plant in a 1:1 digital twin format, using a color gradient to intuitively represent generation levels—deeper blue indicates higher power output, while lighter shades indicate lower output. The following examples illustrate two time points on the same day.
As shown in the morning snapshot (around 9:00 a.m. in February), it is clear that the northeast-facing PV strings on the right side appear in darker colors overall, indicating higher power generation, while the left side shows lighter colors and lower output compared to the right array.
Later in the afternoon, the pattern reverses. In the 13:30 view of the same day, the left array appears in deeper blue tones while the right side becomes lighter, showing that the dominant irradiance shifts to the southwest-facing side.
With AndCloud 3.0, O&M personnel can compare generation variations throughout the day at a glance, gaining a clear understanding of the operating status of each PV module at any time. Compared with traditional rooftop inspections that require manual on-site checks, this module-level visualization approach significantly reduces troubleshooting costs and makes maintenance more efficient and targeted
As a global leader in health and hygiene care, this factory maintains exceptionally high standards for safety. The AndSolar smart rapid shutdown device enables module-level rapid shutdown, reducing system voltage to below 30V within 30 seconds, effectively minimizing the risk of electric shock and ensuring the safety of both personnel and assets. It supports both individual module shutdown and full-system one-click shutdown, allowing flexible response across various operational scenarios. When combined with the AndCloud 3.0, it enables full lifecycle, module-level monitoring and further enhances precise plant management, ensuring that rooftop PV systems in industrial facilities operate with greater safety, reliability, and long-term stability.
AndSolar Technology is a tech-company engaged in photovoltaic module-level power electronics (MLPE) and distributed photovoltaic smart energy overall solutions.
