T1 Energy has secured full ownership of a portfolio of TOPCon solar patents through a $135 million acquisition
T1 Energy reported solar PV module shipments of 835 MW in its preliminary Q2 2026 results

US-based solar PV manufacturer T1 Energy (previously FREYR) has acquired a portfolio of TOPCon solar cell and module patents and related intellectual property (IP) from Singapore-based Evervolt Green Energy Holding in a $135 million deal.
This gives the company full ownership of the technology it had previously licensed from Evervolt.
The acquisition includes foundational patents and other intellectual property (IP) related to TOPCon technology, one of the leading high-efficiency solar cell architectures. TOPCon has become the focus of multiple patent infringement disputes globally (see Rising IP Disputes Complicate TOPCon Expansion).
“The acquisition of the IP provides an important economic benefit to T1, as it eliminates future royalty payments now that T1 owns and controls the IP it previously licensed from Evervolt. This acquisition advances T1's strategy to build America's first fully integrated domestic silicon-based solar supply chain,” the company stated.
Among the key patent holders is US-based First Solar, which acquired certain TOPCon-related patents through its 2013 acquisition of TetraSun. The company has filed patent infringement lawsuits against several manufacturers over the technology. The USITC also initiated a new patent investigation under Section 337 following a complaint by First Solar (see First Solar Complaint Prompts USITC Section 337 Probe).
T1 has also announced preliminary results for Q2 2026. The company expects to report net sales of $245 million to $255 million on module shipments of about 835 MW. However, management expects a net loss of approximately $34 million to $37 million, along with an adjusted EBITDA loss of $ 11.5 million to $ 14.5 million. This excludes close to $24.4 million in tariff refunds under the International Emergency Economic Powers Act (IEEPA).
During the quarter, it monetized its remaining 2025 Section 45X tax credits for $39.1 million and ended the period with $156.4 million in cash. The company said production at its G1_Dallas solar module facility remains on track to reach the upper end of its 2026 guidance of 3.1 GW to 4.2 GW, and it will exceed Q2 volumes in the subsequent quarters (see T1 Energy Keeps 2026 Guidance Despite Wider Net Loss).
Initial production at its G2_Austin solar cell factory is now expected in Q1 2027, rather than the previous target of the end of 2026, due to higher labor and material costs associated with tightness in the Texas data center construction market. As a result, it expects capital expenditure on the facility to be around $510 million, up from the previous guidance of $425 million.
The company recently also entered the battery energy storage system (BESS) and data center infrastructure markets with the acquisition of KORE Power. With this deal, KORE's engineering-focused NRI business will operate under the T1 NRI brand.
The company said the move broadens its offerings beyond solar manufacturing to serve the growing power needs of AI data centers and other large energy users.
