SEG Solar is a US-owned solar module manufacturer founded in 2016 and headquartered in Houston, Texas. SEG Solar is part of the Avangrid Iberdrola Group network, providing access to substantial financial resources and strategic partnership opportunities.
SEG Solar operates a strategically distributed manufacturing footprint across the United States and Indonesia, positioning itself to serve both North American and international markets.
The company has three primary manufacturing bases – facilities in Houston, Texas; Batam, Indonesia; and Central Java, Indonesia.
By the end of 2024, SEG Solar had achieved a module production capacity of over 6GW and successfully shipped more than 6GW of solar modules worldwide. The company is advancing with rapid scaling and market penetration since its founding.
Funding & Investment
Interestingly, there are no external funds taken yet by SEG Solar. The company CEO, Jim Wood, earlier informed that SEG was financed internally and has no private equity.
In June 2025, SEG Solar completed its first transaction for the sale of Section 45X Advanced Manufacturing Production Tax Credits valued at up to USD 50 million. The transaction closed, and initial funding was received on June 6, 2025. As per the firm, these tax credits originate from SEG Solar’s 2025 module production at its Houston facility and represent participation in Inflation Reduction Act (IRA) benefits rather than traditional financing.
The recent commitment of USD 80 million to construct a 3GW ingot and wafer manufacturing facility in Indonesia is fully financed by SEG Solar from retained operational earnings.
Vertically Integrated Supply Chain Expansion
SEG Solar currently operates a module facility in the United States and a solar cell manufacturing facility in Indonesia.
In May 2024, the company commissioned a 2GW solar PV cell manufacturing plant in the Batang Regency of Central Java province, marking a significant milestone in its production expansion.
The company has initiated an ambitious Phase I project to construct a 5GW vertically integrated TOPCon manufacturing plant in Indonesia, spanning from ingots to modules.
A critical component of this expansion includes the construction of a 3GW ingot and wafer manufacturing facility in the Batang Regency, which is specifically designed to support the US solar market through a non-Foreign Entity of Concern (FEOC) supply chain.
