SUNDTA Returns to Iran One Year Later to Commission Growatt Inverters and Optimize 10MW Solar Project

A year after first breaking ground on one of Iran's landmark utility-scale solar initiatives, SUNDTA has returned to the country with its engineering and maintenance team to conduct final commissioning of Growatt inverters and resolve operational issues across the entire 10MW large-scale ground-mounted photovoltaic project. The visit marks a significant milestone in the ongoing partnership between SUNDTA and its Iranian client, demonstrating the company's long-term commitment to project success beyond initial delivery.

The 10MW grid-connected solar project, a collaborative effort between SUNDTA and its Iranian partners, achieved its first major breakthrough when the initial 2.5MW unit was successfully synchronized with the grid. The system utilizes SUNDTA 590W N-type solar panels featuring TOPCon technology with approximately 22.8% higher efficiency, combined with GROWATT 250KW grid-connected inverters known for their transformer-less design and IP66 protection rating. The project exemplifies SUNDTA's end-to-end capabilities, covering everything from initial consultation and system design to procurement, global logistics coordination, and on-site construction support.

SUNDTA is dedicated to providing complete photovoltaic and energy storage solutions for every client, offering integrated systems that span the entire solar-storage application spectrum. From residential energy systems designed for energy independence to commercial and industrial solutions that reduce operational costs and carbon footprints, SUNDTA's approach remains consistent: precision engineering tailored to precise requirements. The company's proprietary design methodology allows customers to scale system sizes according to their energy needs, ensuring flexibility and future adaptability.

What truly sets SUNDTA apart is its professional team, which addresses pre-sales and after-sales technical issues with unmatched expertise. The company maintains a dedicated in-house team of over 50 certified photovoltaic engineers and project managers who oversee every critical phase of project execution, delivering optimized integrated systems tailored to each client's site conditions, energy profiles, and financial objectives. SUNDTA operates its own dedicated factory with independent production lines for lithium batteries and solar panels, ensuring rigorous quality control at every stage of manufacturing. This vertical integration, combined with strategic partnerships with industry leaders such as JINKO and Growatt, guarantees a stable and sufficient supply of high-end components for projects of all scales.

SUNDTA's commitment to client relationships extends far beyond the initial sale. The company maintains overseas presence while also conducting regular international visits to meet clients face-to-face, ensuring that systems continue to operate at peak performance. The recent return to Iran follows a series of high-level engagements, including a productive business visit in August 2025 during which SUNDTA's delegation met with Iran's Renewable Energy Minister, who expressed strong support for the company's vision and technical capabilities. That visit resulted in the signing of a significant 15MW solar agreement, further cementing the strategic partnership.

SUNDTA's holistic approach has earned high praise from clients. Iranian customer representatives have expressed particular appreciation for the company's technical expertise and responsive service, noting that SUNDTA's teams conducted meticulous on-site analysis and developed solutions that perfectly met their energy requirements while accommodating future expansion possibilities. The quality of components, combined with SUNDTA's exceptional project management and timely delivery, has consistently exceeded client expectations.

SUNDTA warmly welcomes global customers to visit its advanced production facilities and operational projects in China, where they can experience firsthand the company's innovative solutions and customer-centric philosophy. Whether for residential solar-storage systems, commercial and industrial installations, or utility-scale ground-mounted projects, SUNDTA delivers perfectly customized solutions with seamless integration. With stable production quality, close cooperation with leading inverter brands, and a professional team dedicated to client success, SUNDTA ensures a reliable and secure supply for its customers around the world.
