Solar Profile Catalog

FRP solar profiles — module frames, rails and supports

Choose module-frame sections, support profiles and rooftop rails from the catalog below. F1 supplies specified pultruded components; connection hardware, fabrication and any assembly scope are confirmed on the quotation.

This page covers component selection and supply. For wind, span and connection considerations, read the PV support design guide →

Three component roles

Profile supply from module edge to support structure

Solar module frame profiles

Custom perimeter, corner-key and clamp-interface profiles for framed PV modules. Geometry is developed around the laminate, glass stack, sealant channel, drainage and module load test.

Composite PV support profiles

Square, C and H sections for fixed ground arrays, agrivoltaics, fishery-PV, floating arrays and coastal structures. Standard connectors remain mechanically fastened and field-serviceable.

Rooftop rails and hardware

Low-line-mass roof rails for BAPV, BIPV and distributed generation, with matched mid clamps, end clamps, splice plates, sliding nuts and roof interfaces.

Catalog sections

Standard FRP solar support and rail profiles

These starting sections cover light rooftop rails through primary ground-mount support. Final section selection is governed by span, module layout, wind uplift, snow, seismic load, connection capacity and the project deflection limit.

Material options

PU for thin-wall performance; polyester or vinyl ester for exposure-led design

Polyurethane (PU) pultrusion

Values are characteristic laminate ranges from the solar-profile program, not design allowables. Project calculations use batch-qualified properties with environmental, duration, temperature, buckling and safety factors applied.

Laboratory evidence

FRP photovoltaic module frame material test reports

Review the tested material, coating and specimen dimensions before applying a result to your module design. These reports concern the identified samples; they do not certify every F1 Composite profile or a complete PV module. Chinese reports include English notes beside each original page. Untouched originals are also available for signature verification.

Frequently Asked Questions

Which photovoltaic products can F1 Composite supply?

The range covers three product families: custom pultruded profiles for solar-module perimeter frames; structural FRP profiles for ground-mount, floating, fishery-PV and agrivoltaic support frames; and lightweight rooftop rails supplied with mid clamps, end clamps, splice plates and roof-clamp interfaces. Profiles can be supplied as cut lineals or as a project-specific component kit.

Can FRP solar mounting rails be used on existing industrial roofs?

Yes. Rooftop retrofit is a strong fit where the original roof has limited dead-load reserve. A typical pultruded GFRP rail weighs about 1.0–1.5 kg/m, compared with roughly 4–6 kg/m for a galvanized-steel rail. Final suitability still requires a project-specific roof survey and structural check for wind uplift, snow, seismic load and connection pull-out.

How are panels and rails connected?

The standard assembly uses sliding nuts with M8×25 fasteners for module mid and end clamps, and M6×12 fasteners for rail splice plates. Standing-seam and trapezoidal-roof interfaces are selected for the roof sheet and can be configured as non-penetrating clamps where the roof geometry permits. Hardware schedules are confirmed with the module and roof drawings.

Which resin system should be specified for PV supports?

UV-stabilized unsaturated polyester is the cost-effective baseline for normal outdoor service. Polyurethane provides the higher characteristic strength and modulus range for thin-wall, stiffness-sensitive sections. Vinyl ester is recommended for offshore, floating, high-salinity, fertilizer and aggressive industrial exposure. The laminate, veil and coating package is selected from the site's exposure class and design life.

Do electrically insulating FRP rails eliminate every grounding requirement?

The FRP members do not create a conductive path and therefore do not need bonding as metallic rails do. The PV modules, inverter, cable system, metallic fasteners and lightning-protection system must still follow the electrical engineer's design and the applicable local code. Electrical isolation of the rail is a system advantage, not a waiver of project grounding and lightning-protection review.
