KEBS (Kenya Bureau of Standards) is the national standards body responsible for setting and enforcing standards for all products sold or used in Kenya, including solar PV equipment. For solar developers, KEBS compliance is a gatekeeper: non-compliant equipment can be blocked at import, rejected by KPLC during grid-connection inspection, and voided for insurance. Understanding which standards apply, how to verify compliance, and what documentation to maintain saves project delays and replacement costs.
This guide covers the KEBS standards applicable to solar equipment in Kenya, the certification process, import requirements, and practical verification steps for developers and installers.
KPLC Inspectors Reject Non-KEBS Equipment on Site
KPLC technical officers conducting interconnection inspections verify that installed equipment matches the documentation submitted with the interconnection application. If the inverter or modules lack KEBS approval, the inspection fails. The system cannot be connected to the grid until compliant equipment is installed. Verify KEBS status before procurement — not after the equipment is on the roof.
Applicable KEBS Standards for Solar Equipment
KEBS adopts international IEC standards as Kenya Standards (KS) with the prefix “KS IEC”. The following standards apply to grid-tied and off-grid solar installations:
| Equipment | Kenya Standard | Equivalent International Standard | Scope |
|---|---|---|---|
| Crystalline silicon PV modules | KS IEC 61215 | IEC 61215:2021 | Design qualification and type approval |
| PV module safety | KS IEC 61730 | IEC 61730:2023 | Safety qualification — construction and testing |
| Thin-film PV modules | KS IEC 61646 | IEC 61646 | Design qualification for thin-film |
| Inverter safety | KS IEC 62109 | IEC 62109-1/2 | Safety of power converters for PV |
| Li-ion battery safety | KS IEC 62619 | IEC 62619:2022 | Safety requirements for secondary lithium cells |
| Solar charge controllers | KS IEC 62093 | IEC 62093 | Balance-of-system components |
| Off-grid solar home systems | KS 1800 | Kenya-specific | Stand-alone solar home systems |
| Salt-mist corrosion (coastal) | KS IEC 61701 | IEC 61701 | Salt-mist corrosion testing for PV modules |
Key Standard Explanations
KS IEC 61215 covers the design qualification and type approval of crystalline silicon terrestrial PV modules. It tests modules for: thermal cycling, humidity freeze, damp heat, mechanical load, hail impact, and insulation. A module that passes KS IEC 61215 is certified to withstand 25 years of outdoor operation under normal conditions.
KS IEC 61730 covers the safety qualification of PV modules. It tests: construction requirements (creepage distances, insulation), electrical safety (isolation, grounding), and fire safety. This standard ensures modules do not present electrical shock or fire hazards when installed.
KS IEC 62109 covers the safety of power converters (inverters, charge controllers) used in PV systems. It addresses: electrical isolation, overcurrent protection, temperature limits, and fault conditions. Grid-tied inverters must comply with this standard for KPLC approval.
KS IEC 62619 covers the safety of secondary lithium cells and batteries used in industrial applications, including solar battery storage. It addresses: overcharge, over-discharge, short circuit, thermal abuse, and crush testing.
The KEBS Certification Process
For Kenyan Manufacturers
Solar equipment manufactured in Kenya must obtain KEBS certification before sale. The process:
Submit product for testing at a KEBS-accredited laboratory
The manufacturer submits product samples to a KEBS-accredited testing laboratory. KEBS maintains a list of accredited labs on kebs.org. For PV modules, testing covers the full KS IEC 61215 and KS IEC 61730 test sequences. For inverters, testing covers KS IEC 62109. Testing duration: 2–4 months for modules (due to long-term stress tests), 2–4 weeks for inverters.
Apply for KEBS Standardization Mark (Diamond Mark)
After successful testing, the manufacturer applies for the KEBS Standardization Mark — the Diamond Mark — which certifies the product meets the applicable Kenya Standard. The application includes: test reports, factory quality control documentation, and product labelling specifications. KEBS may conduct a factory audit before issuing the mark.
Maintain certification through surveillance
KEBS conducts periodic market surveillance and factory audits to ensure ongoing compliance. The manufacturer must notify KEBS of any design changes that could affect compliance. The Diamond Mark is valid for a defined period and requires renewal.
For Imported Equipment
Most solar equipment in Kenya is imported. Importers must obtain the Import Standardization Mark (ISM) before customs clearance.
Verify the product has valid KEBS approval
Before placing an import order, check the KEBS approved products list at kebs.org. Search by brand name and model number. If the product is listed, note the approval number. If the product is not listed, the importer must initiate the KEBS ISM application before shipment.
Apply for Import Standardization Mark (ISM)
The importer submits an ISM application to KEBS with: product specification sheets, manufacturer’s test reports (IEC or equivalent), certificate of conformity from the country of origin (if available), and the import declaration. KEBS reviews the documentation and may request product samples for verification testing.
Obtain ISM certificate and clear customs
Once KEBS issues the ISM certificate, the importer presents it at customs for clearance. Without the ISM, KEBS can request that customs detain the shipment. The ISM certificate should be retained and provided to the installer and end customer.
Verifying KEBS Compliance: Practical Steps
Before Procurement
| Step | Action | Where to Check |
|---|---|---|
| 1 | Search KEBS approved products list | kebs.org — Products > Approved Products |
| 2 | Verify the specific model number | Product list is model-specific, not brand-generic |
| 3 | Check for Diamond Mark on product samples | Physical inspection of product or photos from supplier |
| 4 | Request ISM certificate from importer | Importer should provide ISM certificate number |
| 5 | Cross-check with KEBS customer service | Call KEBS or email with the approval number for confirmation |
During KPLC Inspection
KPLC technical officers may verify KEBS compliance by:
- Checking the inverter model and serial number against the submitted documentation
- Requesting KEBS certificates or datasheets for major equipment
- Visually inspecting for the KEBS Diamond Mark on equipment labels
- Cross-referencing with KEBS market surveillance data
Prepare a compliance folder with:
- KEBS certificates for all major equipment (modules, inverter, battery if applicable)
- Product datasheets showing standard compliance
- ISM certificate (for imported equipment)
- Purchase invoices linking serial numbers to the project
Common KEBS Compliance Scenarios
| Scenario | KEBS Status | Action Required |
|---|---|---|
| Tier 1 module with IEC 61215 + TÜV certification, not on KEBS list | Not KEBS-approved | Importer must apply for ISM before customs clearance |
| Inverter on KEBS approved list, purchased from local distributor | KEBS-approved | Verify Diamond Mark on product; retain purchase documentation |
| Battery with UL 1973 certification, no KEBS entry | Not KEBS-approved | Apply for ISM or select KEBS-approved alternative |
| Module with KEBS approval, but model number differs by one digit | Uncertain | Contact KEBS to confirm if the variant is covered under the same approval |
| Used / second-hand equipment from another country | No KEBS approval | Cannot be legally installed for grid connection; source new KEBS-approved equipment |
Internationally Certified Products Typically Pass KEBS Faster
Products with recognized international certifications (TÜV Rheinland, UL, Intertek, Bureau Veritas) that satisfy the equivalent IEC standards typically move through KEBS ISM review more quickly than uncertified products. The testing data from the international certification body is accepted by KEBS as supporting evidence. Always provide the full international certification package with the ISM application.
KEBS and KPLC: The Inspection Link
KEBS sets the standards. KPLC enforces them at the installation level. The link between the two:
- KPLC interconnection application requires specification of equipment models
- KPLC inspection verifies installed equipment matches the application
- KPLC inspector checks for KEBS compliance as part of technical verification
- KPLC approval is withheld if equipment is non-compliant
KPLC does not conduct its own product testing — it relies on KEBS certification as evidence of compliance. A product with valid KEBS approval should pass KPLC inspection. A product without KEBS approval will fail.
KEBS Enforcement and Penalties
KEBS enforces standards through:
- Import inspection: Customs collaboration to detain non-compliant shipments
- Market surveillance: Random inspection of products in the market
- Complaint-driven investigation: Response to reports of non-compliant products
- KPLC coordination: Feedback from KPLC inspectors on non-compliant equipment found during inspections
Penalties for non-compliance include:
- Seizure and destruction of non-compliant products
- Fines under the Standards Act
- Prohibition on future imports for repeat offenders
- Invalidation of insurance coverage for installations using non-compliant equipment

Frequently Asked Questions
Does KEBS require in-country testing for every imported solar product? No. KEBS accepts test reports from accredited international laboratories (TÜV, UL, Intertek, Bureau Veritas) as supporting evidence for ISM applications. The importer must still apply for the ISM and pay the applicable fees, but the product does not need to be re-tested in Kenya if it already has valid international certification to the equivalent IEC standard. KEBS may request sample verification for certain product categories.
How long does KEBS ISM approval take for imported solar equipment? For products with complete international certification packages, ISM review typically takes 2–4 weeks from submission of a complete application. For products without international certification that require testing in Kenya, the timeline extends to 2–4 months depending on laboratory capacity. Plan procurement timelines to account for ISM processing — do not assume same-week clearance.
Can I install solar equipment purchased before KEBS standards were enforced? Equipment installed before the applicable KEBS standard came into force may be grandfathered, but this is complex and case-specific. For new installations in 2026, use KEBS-compliant equipment. For retrofits or expansions of existing systems, consult KEBS on whether the existing equipment affects the compliance status of the new installation. KPLC inspectors assess the entire installation, not just new components.
What is the difference between the KEBS Diamond Mark and the Import Standardization Mark? The Diamond Mark is the KEBS Standardization Mark awarded to products manufactured in Kenya or fully certified under KEBS standards. The Import Standardization Mark (ISM) is a certificate issued to importers confirming that imported products meet applicable Kenya Standards. For solar equipment, imported products carry the ISM; locally manufactured products carry the Diamond Mark. Both indicate KEBS compliance.
