Yingli Solar is strengthening its focus on utility-scale solar projects as it anticipates what it considers the next major technological leap for the photovoltaic industry: perovskite. The company is already developing tandem solar cells that will incorporate this material into its next generation of modules, aiming to deliver higher efficiency and improved performance under demanding operating conditions.
During the Future Energy Summit – Southern Cone, Andrés Casayas, Yingli Solar’s Lead Manager for the Andean Region, confirmed that the manufacturer is concentrating on consolidating its utility-scale portfolio with technologies that combine innovation, long-term durability and specialised technical support.
“For the future, we see the tandem cell as a key development. This technology will introduce perovskite to enhance solar module performance and make better use of available energy,” Casayas explained. The company believes this innovation represents a turning point in the technological evolution of the PV sector. Through a sustained research and development strategy, Yingli aims to improve energy efficiency under low irradiance and high temperatures, prioritising low degradation rates and strong thermal behaviour.
Beyond its long-term vision, Yingli Solar is already applying advanced technological improvements to its current products. Casayas noted that the company’s modules—particularly the N-Type TOPCon line—offer high bifaciality, low degradation and proven durability, all essential for large-scale solar deployment.
“This technology brings very concrete benefits: strong efficiency in extreme conditions such as low irradiance and high temperatures, a 30-year power output warranty, and a degradation rate of 1% in the first year and 0.4% annually thereafter,” he said.
In terms of execution, the company is involved in major international projects, reinforcing its global presence and operational capacity. “We are supplying modules for a 1.25 GW project in the Middle East,” Casayas highlighted, referring to one of Yingli Solar’s most recent global milestones.
He also emphasised that this technological rollout is supported by direct technical assistance during construction phases, which the company considers essential for ensuring successful project delivery.
For the Chilean market in particular, Yingli reaffirmed its interest in continuing to support the utility-scale segment, underlining its focus on efficiency and on the integration of energy storage.
“We intend to continue accompanying utility-scale plants with N-Type TOPCon technology to make solar power generation more efficient. The progressive integration of storage is also a very positive development for Chile,” Casayas said. He added that Yingli Solar’s approach goes beyond the technological dimension, noting that technical support and energy efficiency are essential pillars for sectoral growth and for meeting the international commitments established under COP23.
With a combination of technological innovation, international experience and specialised support, Yingli Solar aims to consolidate its role as a strategic player in Latin America’s energy transition, positioning Chile as a priority market for high-efficiency photovoltaic solutions.
