Where does SolarEdge Technologies source its components?
Israel. Supply chain mapped to 46 inputs across 13 countries.
Federal screeningClean
No federal designation found. SolarEdge Technologies is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List), and Israel is not a covered nation under the FEOC rules. Is SolarEdge Technologies a Foreign Entity of Concern?

Sources and methodology
Research-based supply-chain map compiled from public sources - not an audited bill of materials. Tiers reflect the standard industry structure for this product. Sourcing risk on a node describes where that input is typically mined or refined; it is not a FEOC determination for SolarEdge Technologies, and it is not a screening result for the node itself unless a federal listing is cited against it. Verify against primary documentation before making a compliance determination.

Common questions
- Where does SolarEdge Technologies source the inputs in this product?
- This map traces 46 inputs across 13 countries, including 17 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
- How much of the SolarEdge Technologies supply chain sits in a covered nation?
- 28 of 46 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 17 carry elevated sourcing risk without either basis.
- Is SolarEdge Technologies itself a Foreign Entity of Concern?
- No federal designation found. SolarEdge Technologies is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List), and Israel is not a covered nation under the FEOC rules. Sourcing risk in this map describes where inputs are mined and refined and is a separate question from the company's own federal screening.
