Riverclack Solar PV
Photovoltaic modules fixed to the patented seam — no drilling, no breach of the watertight envelope, no loss of roof warranty.
Introduction
Photovoltaic modules fixed to the patented seam — no drilling, no breach of the watertight envelope, no loss of roof warranty.
iverclack solar roofing is the integration of the base standing-seam roof line with a dedicated photovoltaic mounting system. The fundamental difference from standard BIPV solutions: PV panels are fixed to the roof without a single through-hole. The Riverclack clip lock receives a profile clamp that grips the module frame directly on the seam; no screw or anchor crosses the plane of the metal sheet. The roofing blanket remains absolutely watertight, and the manufacturer's warranty on water resistance is preserved in full.
This matters in particular for Russian industrial and logistics sites, where the reliability requirements of the roof and the payback horizon of the PV installation are both measured in decades. Any through-fastener in a traditional BIPV scheme is a potential leak 5–10 years after installation. Riverclack removes that risk architecturally. Terra-Zenith is the authorised Riverclack dealer in Russia: integrated roof and PV system design from a single point of accountability.
How PV panels are mounted without perforating the roof
On a conventional standing-seam roof, PV modules are fixed via a through-screw at the rib of the seam with a sealing washer — and every such opening becomes a potential leak over time. Riverclack uses an entirely different mechanism: a profile clamp with aluminium jaws snaps onto the seam from above and holds the module frame by its own clamping force. Because the Riverclack seam is a load-bearing element by design, wind and snow loads from the PV module are transferred to the roof with no localised stress concentration.
The solution is compatible with most standard crystalline PV modules in an aluminium frame. Module layout on the roof is planned with the drainage channels of the seam in mind — ensuring unobstructed melt-water runoff and preventing snow build-up under the PV array.
Energy efficiency for industrial buildings
Large flat or low-slope roofs over logistics centres, manufacturing halls and trade-distribution complexes are the natural site for a large PV installation. Riverclack allows photovoltaics to be added to that same roof without doubling the substructure and without a separate bearing frame for the panels. The PV array is mounted directly on the roof lock, reducing total cost of ownership and simplifying system maintenance.
The roof sheet surface withstands a point load of up to 400 kg, allowing maintenance staff to service the PV array by walking directly on the roof — with no dedicated walkways or transition platforms. This is a meaningful operational advantage for large PV fields.
Compatibility and service in Russia
The Riverclack profile clamp is compatible with most standard crystalline PV modules in an aluminium frame 30–40 mm thick. The specific configuration is selected for the chosen module brand at the design stage. Terra-Zenith performs wind- and snow-load calculations to SP 20.13330 accounting for the additional mass of the PV array, and coordinates the solution with the Riverclack factory.
The EN AW 5754-H18 aluminium of the seam sheet is resistant to freeze-thaw cycles and is not corroded under the PV array. The clip allows free thermal expansion of the sheet independently of the PV clamps installed on it — removing the risk of thermal stress that is characteristic of rigidly fastened BIPV solutions.

Frequently Asked Questions
Frequently Asked Questions
Is the roof perforated when the PV system is installed?
No. The Riverclack profile clamp snaps onto the seam from above and holds the PV module frame by its own clamping force. No screw or anchor crosses the plane of the metal sheet.
Is the manufacturer's water-tightness warranty preserved?
Yes. Because the roofing blanket is not perforated during PV installation, the Riverclack factory warranty on roof watertightness is preserved in full. This is the key advantage over standard BIPV solutions with through-fasteners.
Which PV modules are compatible with the system?
The profile clamp is compatible with most standard crystalline PV modules in an aluminium frame 30–40 mm thick. The specific configuration is selected for the chosen module brand at the design stage.
Is the system suitable for cold Russian climates?
Yes. The EN AW 5754-H18 aluminium is resistant to freeze-thaw cycles, and the drainage channels of the seam evacuate melt water from under the PV array. Snow loads are calculated to SP 20.13330 for the specific climatic zone.
Can the roof be walked on to service the PV array?
Yes. The Riverclack roof sheet supports a point load of up to 400 kg — allowing maintenance staff to service the PV array by walking directly on the roof, with no dedicated walkways or transition platforms.
