What is ISOSIDE?
ISOSIDE is an economical and robust mounting system developed for solar panel installation on trapezoidal and sandwich-clad industrial roofs. The core of the system, the XSide bracket, is applied by screwing it into the corrugation; this prevents the roof covering from being punctured and eliminates the risk of leaks.
Thanks to the pre-drilled holes on the XSide fittings, no burrs are formed during application, and there is no risk of corrosion. The front-glued EPDM seal on the back of the fitting creates an additional water barrier between the XSide and the roofing material. Permanent sealing is ensured with sealed pointed screws or watertight rivets.
With four different ISOBEAM profile heights (30, 45, 60, 85 mm), ISOSIDE adapts to any roof configuration and supports both horizontal and vertical panel placement. It is an ideal, fast, and reliable solution for industrial facilities seeking to maximize energy production.

System Components
Panel carrier main rail profile (AL 6063-T66). 30/45/60/85 mm height options. It is placed in the channel of the XSide adapter and secured with Allen screws.
A connector for joining two ISOBEAM profiles end-to-end. It is inserted into the profile and secured with a self-tapping screw.
It provides protection and an aesthetic appearance by covering the exposed end of the profile.
Universal end clamp for the exposed edges of panels. Compatible with all PV modules with a 30-45 mm frame.
Universal center clamp for edges between two panels. Compatible with all ISOTEC systems.
ETA certified screw with hardened tip and gasket. It does not create burrs during screwing and provides a leak-proof seal by securing the XSide adapter to the roof.
Special rivet with EPDM gasket. An alternative fastening element with guaranteed leak-proof properties.
Easy Assembly
-
1Marking and Placement According to the panel layout plan, the rib sides where the XSide brackets will be mounted are determined and marked.
-
2XSide Fixing XSide fittings are secured to the roof via pre-drilled holes on the sides of the corrugation using sealed pointed screws or rivets. Observe that the EPDM seals are compressed.
-
3ISOBEAM Profile Assembly ISOBEAM profiles are placed into the channel of the XSide adapter, and the profile is secured by tightening the Allen screw on the adapter.
-
4Profile Merging and Cover To ensure system continuity, profiles are joined end-to-end with ISOBEAM Connectors. ISOBEAM Caps are fitted to the ends.
-
5Panel Assembly The EasyClamp End is placed in the profile channel at the beginning and end of the system. The solar panel is placed in the system and secured by tightening the EasyClamp End.
-
6Intermediate Clamp and Completion EasyClamp Middle adapters are added and tightened between the two panels. The system is now complete.

BF Device · Bifacial Shading Advantage
There are two different approaches in the industry. Why is ISOTEC's BF apparatus both economical and high-performing?
Why is shading important in bifacial panels?
Bifacial (double-sided) solar panels generate electricity from both their front and back surfaces. The back surface captures radiation reflected from the ground and coming from the side edges — typically. %15-20 ek üretim provides.
The critical point: Any part (purlin, beam, cable) that blocks light falling on the back surface of the panel → on the back surface shadow lines It creates a shadow, and the cells under this shadow lose productivity. Between the purlin and the panel... distance and the purlin cross-sectional area These are the determining parameters.
Therefore, to get the most out of a bifacial investment, the design of the mounting system is critical.
Two Design Philosophies in the Industry
There are two main approaches in the industry to reduce bifacial shadowing:
Inclined C-Beam competitors
The beam runs parallel to the panel at the same angle. A single long C-profile provides grip along the panel.
- ✓ Minimal shade, high bifacial yield.
- ✗ Long steel beams, high material costs.
- ✗ In sloping structures, column heights vary.
- ✗ Tolerances are tight, assembly takes a long time.
Vertical Beam + Horizontal Z-Purlin ISOTEC + BF
The beams are vertical (perpendicular to the ground, short). The Z-profile purlins extend horizontally. A BF 56 mm spacer is inserted between the purlin and the panel.
- ✓ Low steel content, quick assembly, economical.
- ✓ Bifacial performance with BF apparatus and Inclined-C equal
- ✓ Standard column, easy supply.
- ✓ Slot design compatible with thermal expansion.
CAD comparison — purlin-panel distances
How does the BF adapter work?
The ISOTEC BF adapter is a device placed between the Z-shaped purlin and the bottom surface of the panel. spacer + clamp systemIt maximizes the radiation falling on the back surface of the panel by creating a distance of 56 mm.
Design features
- Spacer body: EN AW-6005A T6 anodized aluminum (3.0 mm wall)
- Distance: The distance between the purlin's top surface and the panel's bottom surface is 56 mm.
- Slot design: Panel thermal expansion accommodated (±2 mm tolerance)
- Screw: Stainless steel A2 M8×40 hexagonal
Clamp variations
| Code | Medicine | Use |
|---|---|---|
| BFC | Glass-to-glass edge | For frameless glass-to-glass panels at panel edges. |
| BFC-E | Medium grip | Center panel, shared grip, frameless. |
| BFC-SET | Complete set | All components are pre-packaged, quick assembly. |

Bifacial Radiance Simulation Results
The results are from NREL's (US National Renewable Energy Laboratory) open-source program. Bifacial Radiance This was achieved using a Python library. A scanner-based radiation calculation is performed that accurately reflects field conditions.
Heat map comparison
Warm (yellow) colors indicate high irradiation (1.77 MWh/m² annually), while cool (blue) colors indicate shaded areas. In both systems, the front surface of the panel (the upper yellow area) receives homogeneous irradiation; the difference is the panel. on the back surface It is seen.
Numerical results
| System | Bifacial Gain | Shadow Line | Cost |
|---|---|---|---|
| Sloping-C (Opponent) | ~%18-20 | 1 big | 💰💰💰 High |
| ISOTEC + BF Adapter | %18 | 2 small | 💰 Economical |
| ISOTEC (without BF adapter) | ~%10-12 | 2 nearby shadows | 💰 Lowest |
The same bifacial production, shorter beam, less steel, faster assembly. The cost difference is significant at the field scale.
