Description
The Most-Installed End-Clamp Size in Kenya
The SFS-ECN2-35AL is the 35mm-specific end-clamp that holds together the largest segment of Kenya’s installed solar base. From the first wave of residential rooftop installations in the mid-2010s through the recent commercial expansion, 35mm aluminum frames have been the dominant panel format across the country. Every one of those panel rows is held to its rails by four end-clamps — and over time, those end-clamps need inspection, occasional replacement, and matching hardware when new panels are added to existing arrays.
This product is the precision-fit answer for any 35mm-frame installation, whether new-build or maintenance. The clamp body is extruded from 6005-T5 structural anodized aluminum with SS304 stainless steel fasteners; the J-profile geometry is dimensioned exactly for the 35mm frame thickness. The longer M8×30 bolt (versus the M8×22 used on the 30mm variant) accommodates the thicker frame profile and ensures full thread engagement with the rail nut at final torque.

Use Cases for the 35mm End-Clamp
The ECN2-35AL covers four common scenarios in the Kenyan solar market:
- New residential installations using 35mm-frame panels — still the most cost-effective panel format for many home-scale projects.
- Array expansion on existing 35mm-frame systems — adding new panels to a previously installed array, where the new panels must be clamped with the same hardware specification as the existing array to maintain uniform structural behaviour.
- Maintenance and replacement on aging installations where original end-clamps have begun showing wear, corrosion, or thread damage. Replacing aging end-clamps at year 10–15 of service is standard preventive maintenance.
- Storm damage repair following coastal monsoon or highland windstorm events where individual clamps have failed and need immediate replacement.
Why the 35mm Size Is Standard-Stock
Unlike specialty sizes that retailers treat as special-order items, the 35mm end-clamp is held as a continuous stock line because it covers the largest single panel population in Kenya. This has practical advantages for buyers:
- Immediate availability. Same-day dispatch from Nairobi for stocked quantities — no waiting for special-order imports.
- Predictable pricing. Standard-stock items are not subject to the price volatility that affects low-volume specialty SKUs.
- Bulk availability. Project-scale quantities (50+ clamps) can usually be filled from stock, with larger volumes available on short notice.
- Replacement convenience. When a single clamp fails on an existing array, a same-day replacement is available without having to source from overseas.
End-Clamp Quantities for Any Array Layout
End-clamps follow a flat quantity rule: 4 per panel row, regardless of panel count. The table below covers common Kenyan installation sizes:
| Array Configuration | End-Clamps Required | Pairing Mid-Clamps Required |
|---|---|---|
| Single row, 4 panels | 4 | 6 |
| Single row, 8 panels | 4 | 14 |
| Two rows of 6 panels | 8 | 20 |
| Two rows of 10 panels | 8 | 36 |
| Three rows of 8 panels | 12 | 42 |
| Four rows of 10 panels | 16 | 72 |
| Five rows of 12 panels | 20 | 110 |
Use the solar calculator for non-standard layouts. Always order an extra 4–6 end-clamps beyond the calculated quantity as installation-day spares — clamps occasionally drop off rooftops or get damaged during handling.
Pairing the 35mm End-Clamp With Other Components
- Matching mid-clamps: The SFS-MC3N2-35AL is the 35mm-specific mid-clamp that pairs with this end-clamp for a consistent 35mm array build.
- Aluminum mounting rails: Standard 38mm-channel rails for residential and small commercial spans.
- Roof anchor points: The TRG-series tin roof clamps for mabati installations or LFN2S L-feet for timber-frame roofs.
- Earthing components: An ELN2-20AL earth lug bonds the rail system to ground; GC-01 grounding clips bond each panel frame to the rail.
- Solar panels: Browse our 35mm-frame solar panel range.
- Power conversion: Match panel count and load to a hybrid inverter from 3.5kW to 15kW.
- Energy storage: Pair with a lithium battery for evening backup.
