PVTIME – On June 23, the opening day of Intersolar Europe, Hanersun officially signed a 50MWh energy storage systems and 150MW solar modules supply agreement with leading Spanish distributor SeisSolar. The signing ceremony was attended by Liu Yunzhou, CEO of Hanersun, and Miguel Navarro, Co Founder of SeisSolar.
Under the agreement, Hanersun will supply 50MWh of its HNS 261K-125P liquid-cooled C&I energy storage system, supporting applications such as peak shaving, PV self-consumption, and backup power, helping commercial and industrial users improve energy efficiency and optimize electricity costs. For the solar segment, Hanersun will continue supplying its HITOUCH N series high-efficiency modules, featuring high power output, low degradation, and strong temperature performance to maximize energy yield and reduce lifecycle LCOE.Building on a successful 100MW collaboration in 2025, this renewed agreement marks a mature, stabilized phase in the partnership and underscores both companies’ commitment to deepening their presence in the Iberian market.
Headquartered in Madrid, SeisSolar is a leading distributor of PV products across the Iberian Peninsula and North Africa, covering channel distribution and project supply for modules, inverters and energy storage equipment. The company has built a comprehensive distribution network and localized service system across Europe, North Africa and Latin America, with a strong regional channel presence.
Since their partnership began in 2025, Hanersun has delivered batches of high-efficiency HITOUCH N series modules to SeisSolar, powering diverse projects including distributed C&I, residential and utility-scale plants. Hanersun’s stable and reliable product performance, precise and efficient delivery system, and responsive technical and after-sales support have won consistent praise from SeisSolar and its end users, laying a solid foundation for this expanded cooperation.
“A repeat order from a long-standing client is the most direct market endorsement of Hanersun,” said Liu Yunzhou, CEO of Hanersun. “Over the past year, we have worked closely with SeisSolar in Spain and surrounding markets, forming a mature and efficient model of collaboration across products, projects and customer service. Going forward, we will continue to empower SeisSolar in consolidating and expanding its competitiveness in Iberia and beyond.”
Miguel Navarro, co founder of SeisSolar, expressed high confidence in the partnership: “Expanding our cooperation at this scale is a natural choice built on a strong partnership foundation and shared market goals. We look forward to working alongside Hanersun to bring more advanced and reliable energy solutions to Spain and the broader regional market.”
Spain’s solar market remains one of Europe’s most mature and dynamic, with annual installations approaching 10GW and its cumulative 2030 target recently raised to 76GW. Backed by supportive policy, the market’s growth potential continues to unfold.
Looking ahead, Hanersun will continue to work closely with SeisSolar, providing efficient and reliable products, stable delivery and a comprehensive service system to support the high-quality development of the renewable energy market in Spain and the wider Iberian region.
