The 400 MW line in Salalah, Oman, built by Ecoprogetti, supports AACE’s manufacturing portfolio
It covers all manufacturing steps and supports the assembly of TOPCon and HJT technologies
With 2 completed factories in Oman, Ecoprogetti says it now holds a majority share of the country’s solar module production market
Ecoprogetti, an Italian turnkey solar PV equipment maker, has commissioned and fully ramped up a new 400 MW fully automated module assembly line in Oman. Built for US solar PV module manufacturer American Advanced Clean Energy (AACE), the line uses advanced technologies to produce TOPCon and heterojunction (HJT) solar modules.
AACE operates production facilities and an R&D division in Oman, and it plans to export the modules produced to the US under the Free Trade Agreement between the US and Oman. The company says its modules are UL- and IEC-certified. AACE plans further vertical expansion in the future.
The new 400 MW line in Salalah was designed and built in Italy by Ecoprogetti. It covers every stage of the process, right from stringing and lay-up to lamination, framing, and testing, with the most advanced quality inspection systems. Ecoprogetti says the line is flexible and adaptable to evolving technologies and market needs.
In 2024, the Italian manufacturer installed a 50 MW module line for Sheida Industries in the Sohar region of Oman to roll out TOPCon panels. With both these factories now fully ramped up, Ecoprogetti claims it holds the majority of the Omani market share.
“With two plants now operating from north to south, Ecoprogetti is proud to support the growth of the local photovoltaic value chain and the country’s vision for a sustainable energy future,” said Ecoprogetti CEO Laura Sartore.
Oman is emerging as a major solar PV manufacturing hub in the Middle East, going by the various upstream announcements in the recent past, mostly made by Chinese manufacturers that explore the region as other big markets like the US, India, and Europe impose protectionist measures and stringent conditions aimed at supporting local industry players.
These include a 100,000 tons/year polysilicon plant of United Solar Holding, Hainan Drinda New Energy’s 5 GW solar cell fab, and JA Solar’s 9 GW cell and module facilities (see China’s JA Solar Heads To Oman With 9 GW Solar Manufacturing Plans).
