Whenever the music starts, Xinlonghu Performing Arts Center It has transformed into Changzhou’s most vibrant music venue. As the city’s first large‑scale, indoor performance landmark capable of hosting over ten thousand attendees and a signature landmark of the High‑Speed Rail New City, it has recently played host to a series of blockbuster concerts, drawing tens of thousands of fans. A sea of glow sticks illuminated the 71‑meter‑wide, column‑free dome, while waves of sound reverberated along the banks of the New Longhu Lake. Stage lighting, large-screen audio systems, central air conditioning… With a venue accommodating tens of thousands of people operating around the clock, energy consumption is enormous, and Cando quietly provides green, clean energy for every musical event.

To support the city’s “dual carbon” initiative and create a zero-carbon, model cultural and sports landmark, the venue selected Cando’s Firm-light® series photovoltaic modules as the core power-generation equipment for this project, completing the construction of a 0.615 MW distributed photovoltaic system and establishing a green-energy benchmark for large-scale cultural and sports facilities.

 

Why choose Cando’s Firm-light® series photovoltaic modules?

 

Ultra-lightweight and exceptionally versatile. Firm-light® weighs only 5.9 kg/m², more than 50% lighter than conventional photovoltaic modules, eliminating the need for extensive roof reinforcement and seamlessly integrating with the Performing Arts Center’s 71-meter‑span steel truss roof without compromising the existing building structure or waterproofing layer. 
 

High‑intensity outdoor durability, suitable for long‑term operation in public venues. Firm-light® leverages the company’s more than twenty years of technological expertise and is… The world’s first lightweight, rigid module to earn TÜV Rheinland’s Grade AAA quality certification, delivering maximum safety and reliability to meet the demands of year-round, uninterrupted operations at venues. Its four-sided anti‑dust design further reduces O&M costs for photovoltaic power plants, ensuring both safety and peace of mind. 
 

Efficient and stable power generation, enabling venues to generate and consume their own green electricity. On clear days, the system continuously generates clean electricity to power venue lighting, stage equipment, and ancillary facilities, significantly reducing reliance on grid‑supplied power and cutting carbon emissions with every concert. Based on outdoor field tests and real‑world project measurements, the Firm-light® series modules can boost overall actual energy generation by 5–10%, delivering tangible increases in green value.

 

 

This project is a benchmark case for lightweight photovoltaic systems at a large cultural and sports landmark in Changzhou, demonstrating the outstanding performance of Cando’s Firm-light® product series in large-span public venues, uniquely shaped landmark buildings, and roof applications with load constraints. As a domestic company deeply committed to the lightweight photovoltaic sector, in addition to its conventional photovoltaic module technology platform, Cando also boasts two other core technology platforms—Firm-light® and Taiyangbu—covering urban landmark BIPV/ BAPV It offers one-stop, lightweight photovoltaic integrated solutions for diverse applications—including industrial and commercial rooftops, green buildings, transportation hubs, mobile platforms, low‑altitude infrastructure, and space‑based solar power—serving cultural and tourism venues, public‑building projects, and industrial parks across various regions.

 

Music conveys passion, and photovoltaics safeguard the blue sky. As thousands of glowing lights in the audience merge into a sea of illumination, thousands of Cando’s lightweight, rigid solar panels on rooftops quietly capture sunlight, converting it into electricity—ensuring that every chorus and every celebration stays on the path of low-carbon sustainability!
