Supplier Candidate Registry
Bounded registry explaining how CitizenSolar screens supplier candidates for provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness.
Diligence Registry
Supplier inclusion means candidate for diligence, not approved vendor status
This route makes the supplier screen public without turning a diligence registry into an endorsement list.
Supplier inclusion means diligence candidate only, not approved supplier, certified compliant provider, guaranteed eligible product, procurement approval, finance eligibility confirmation, or CitizenSolar endorsement.
Named suppliers are candidate entries for diligence only. Inclusion is not approval, certification, procurement clearance, warranty validation, or endorsement.

Five-Score Supplier Screen
Hero: Supplier Candidate Registry
CitizenSolar uses a supplier candidate registry to explain how hardware stacks enter diligence before they are considered for finance-aware Energy System Packs.
- • Provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness are screened together.
- • Named suppliers are candidates for diligence only.
- • No supplier enters a pack without documentation, service-route, warranty-route, firmware-authority, cloud, regional-suitability, and integration review.
What this registry is
This registry is a diligence starting point for buyers and partners who need to understand how supplier candidates are screened before human review.
- • A public explanation of the screening logic behind provider-fit and sovereign/control-chain review.
- • A route into supplier evidence gathering before a finance-fit or regional pack conversation becomes concrete.
- • A bounded public layer above the existing USA, EU, regional, and five-score surfaces.
What this registry is not
This route must not be read as approval, certification, or endorsement.
- • Not an approved supplier list.
- • Not a certified compliance registry.
- • Not procurement approval, warranty validation, finance eligibility confirmation, or CitizenSolar endorsement.
Five-score supplier screen
Supplier candidates are screened through the same five readiness classifications used in the public pack model.
| Score | What it screens | Boundary |
|---|---|---|
| CS-PROVIDER-FIT | Supplier / hardware / warranty / service suitability. | Readiness classification only, not approval, certification, or endorsement. |
| CS-SOV-STACK | Cyber, firmware, remote access, cloud, and control-chain posture. | Readiness classification only, not approval, certification, or endorsement. |
| CS-FINANCE-FIT | Evidence relevant to grants, tax credits, loans, leases, and beneficiary compliance. | Readiness classification only, not approval, certification, or endorsement. |
| CS-ORCHESTRATION-FIT | Telemetry, device identity, control boundary, reserve policy, and audit readiness. | Readiness classification only, not approval, certification, or endorsement. |
| CS-CEB-FIT | Community Energy Bank ledger and reporting readiness where applicable. | Readiness classification only, not approval, certification, or endorsement. |
Supplier evidence checklist
A supplier candidate is only useful when the evidence stack is explicit enough for provider, sovereign, finance, orchestration, and Community Energy Bank review.
| Evidence item | Why it matters |
|---|---|
| datasheets | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| certifications and compliance documents where available | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| warranty route | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| service route | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| installer availability | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| firmware/update authority | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| SBOM or software-component evidence where available | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| cloud / remote monitoring jurisdiction | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| remote access posture | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| BMS / EMS / inverter interface documentation | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| telemetry export capability | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| cyber/control-chain posture | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| public-sector suitability notes | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| finance-readiness evidence | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
| regional availability | Used to test provider fit, sovereign/control-chain posture, finance evidence, orchestration readiness, and Community Energy Bank readiness where applicable. |
USA supplier candidates
The USA supplier layer is aimed at storage-first pack candidates where FEOC/PFE sensitivity, domestic-content evidence, and successor-service risks may matter.
| Category | Candidates | Boundary / caution |
|---|---|---|
| Storage / BESS candidates | Fluence; Tesla Energy / Megapack; Eos Energy; Energy Vault; FlexGen; EticaAG candidate - evidence review required | Supplier inclusion means diligence candidate only, not approved supplier, certified compliant provider, or guaranteed eligible product. |
| Inverter / PCS / electrical candidates | EPC Power; Yaskawa Solectria; SolarEdge U.S. commercial line; Sol-Ark; Enphase; Schneider Electric | Powin legacy assets require successor-service and warranty diligence. |
EU supplier candidates
The EU supplier layer is aimed at public-sector, community-storage, and sovereign/control-chain-sensitive projects where CRA/NIS2 and Community Energy Bank fit may matter.
| Category | Candidates | Boundary / caution |
|---|---|---|
| Storage / BESS candidates | FENECON; TESVOLT; Alfen; Saft / TotalEnergies; Nidec Conversion; Leclanche; Northvolt / successor European cell routes - caution, verify current status | Supplier inclusion means diligence candidate only, not approved supplier, certified compliant provider, or guaranteed eligible product. |
| Inverter / PCS / electrical candidates | SMA; Fronius; Ingeteam; Power Electronics; KACO New Energy; Schneider Electric; SolarEdge EU / Israel-allied; Nidec Conversion | CRA, NIS2, firmware authority, and sovereign/control-chain posture remain review items. |
How suppliers enter Energy System Packs
No supplier enters a CitizenSolar Energy System Pack unless the candidate can survive a bounded diligence pass.
- • Document the datasheet, compliance, warranty, service, installer, and firmware-update route.
- • Screen remote access, cloud jurisdiction, control-chain posture, and telemetry/export capability.
- • Tie the candidate into the relevant pack, region, buyer class, finance route, and Community Energy Bank relevance before escalation.
Boundary note
This registry is a diligence starting point. It is not an approved supplier list, certified compliance registry, procurement approval, warranty validation, finance eligibility confirmation, or endorsement.
- • Supplier inclusion means diligence candidate only, not approved supplier, certified compliant provider, guaranteed eligible product, procurement approval, finance eligibility confirmation, or CitizenSolar endorsement.
- • All candidate status, service-route claims, successor-service posture, and regional availability must be refreshed before reliance.
CTA block
Use the supplier registry when the next step is evidence gathering and candidate screening, not procurement or approval claims.
- • Start supplier candidate intake if the main question is whether a candidate can enter diligence at all.
- • Request a finance-fit energy system review if the supplier question sits inside a broader pack or funding discussion.
- • Open five-score screening if the counterpart needs the public readiness-classification model explained first.
