Compliance & Supply Chain Integrity FEOC-Compliant and IRA-Eligible:

All Grid Foundries modules and upstream supply chains are fully compliant with Foreign Entity of Concern (FEOC) restrictions and structured to qualify for incentives under the Inflation Reduction Act (IRA). All materials and vendors are rigorously vetted for legal traceability and compliance.



Team & Track Record:

Grid Foundries is operated by industry veterans with over 2 GW of solar projects developed and more than 1.5 GW of solar module manufacturing already built and commissioned. Our engineering, operations, and procurement teams are embedded, experienced, and ready to scale.

Built From a Position of Strength:
• Our permanent, in-house engineering team ensures continuity from facility design through commissioning.
• Our leadership and technical teams recently completed construction and startup of the US Modules factory in College Station, Texas—a 1.5 GW+ facility producing licensed Tier 1 product.

Facility Development & Engineering Team:

Grid Foundries is preparing to begin development of its flagship OEM manufacturing facility in Lathrop, California. This facility will anchor our domestic module production strategy and scale to support Tier 1 OEM partners. Strategically located in California’s Central Valley, the Lathrop site offers immediate access to critical infrastructure—including interstate highways, rail, and port logistics—to streamline domestic and international supply chain operations.

The Lathrop facility is being designed from the ground up with OEM flexibility at its core. Modular production bays, on-site labs, full QMS infrastructure, and digital twin-based engineering allow us to support evolving formats and partner-specific needs with minimal retooling. Our embedded engineering team—already active on site—guides every design and construction detail.


Manufacturing Intelligence Built In:

At Grid Foundries, quality is not a checkpoint—it’s designed into every layer of the process. From simulation to shipping, our systems use AI, data analytics, and statistical quality control to ensure every module meets rigorous Tier 1 standards.


Full Quality Management System:
• Statistical process control (SPC) with full traceability across batches, materials, and tooling
• Process information and data retention drives quality with every step
• Closed-loop quality feedback integrated with ERP, MES, and logistics platforms


We leverage:
• Digital twins of our production lines to simulate and optimize manufacturing before ramp-up
• In-line sensors and AI-enhanced analytics to detect deviations in real time
• Full automation traceability throughout manufacturing



Digital simulation ("digital twins") of manufacturing line allows for process control optimization inside the computer and for manufacturing visibility once the line is operating

Data & Quality Standards - Our operational systems are being designed to achieve and maintain compliance with:
• ISO 9001 (Quality Management)
• ISO 14001 (Environmental Management)
• ISO 45001 (Occupational Health and Safety)

This system ensures that every module shipped meets the performance, reliability, and durability standards expected by Tier 1 OEMs and their customers.
