FAQs: Aluminum Extrusion Connectors for Solar Applications

These are connectors designed for modular solar mounting and raking systems. They are designed to be precision joining connectors for aluminum profiles in solar structures. Examples include corner brackets for creating a rectangular frame and joining profiles at 90-degrees. T-slot connectors are used for nuts to be placed in the extruded channels. Splice plates are used in joining profiles end-to-end to extend the length. Angle brackets are meant for non-perpendicular connections while hinge connectors are for adjustable disconnects. End caps are used to seal profile channels to protect them end to end. Mounting feet are used to connect racking to the roof or foundations. There are also composite connectors for curved profile joints. There are multi-way connectors designed to join 3 to 6 profiles. These connectors also have integrated bonding lugs intended for electrical grounding.

The 6061-T6 option offers reliable strength with 240 MPa yield strength for industrial applications, incomparable corrosion resistance for over 25 years in outdoor exposure, good fabrication for intricate designs, and the option of welding for assembly and the solar applications the aluminum is used in is the 6063-T6 proven. 6063-T6 strength is good, but with a great finish for anodizing, good extrusion for complex structures, and it is cheap for mild-load joints. The 6005-T5 aluminum offers good strength and corrosion resistance for the European solar market, ease of fabrication for medium strength, and application in weaker solar markets. The die-cast aluminum ADC12 and A380 is ideal for low-cost and high-volume fabrication for complex and thin-walled connectors for mass production.

Multi-axis CNC milling performs the complex interlocking joints required for mount connectors. Coordinates drilling of bolt holes on standard extrusion is done with position accuracy of ±0.005 inches. Taps for assembly fasteners, counterbore recessed areas for flush mount fasteners, and chamfer edges for easy extrusion. Edges are deburred for safety of the installer and in preparation for anodizing. For die-casted connectors, CNC secondary machining for critical and threaded interfaces takes place.

Connectors have hollow sections and thus have machining tolerances of ±0.005 inches for offshore clients with bolt hole positions compatibility with standard extrusion T-slots mapped at 25mm, 30mm, 40mm, and 45mm spacing, flatness of mating surfaces within 0.010 inches for uniform load transfer, threaded holes position complying with ISO-metric and UNC standard, precision of ±0.008 inches on critical dimension for proper fitting within the channels extruded, ±1 degrees on critical angle dimension for perpendicular connections, and overall ±0.015 inches on connectors dimensions for field assembly that won’t be fit for outside modification.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

All components are manufactured under ISO 9001 quality management systems with complete material traceability, dimensional verification against design specifications, connection strength testing documentation, corrosion resistance validation through salt spray testing meeting ASTM B117 standards exceeding 1000 hours, and compliance with solar racking standards including UL 2703 and IEC 61215 ensuring reliable structural connections, electrical continuity for bonding when required, and service life exceeding 25 years.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

The standard corner brackets and T-slot connectors take 8–14 business days which includes machining, tapping and anodizing, while custom multi-way connectors with complex geometries take 3–5 weeks. Connectors for prototypes also for structural testing can be done in 6–10 days which helps in rapidly validating the solar racking system.

Yes. We create high-strength connectors for extended cantilever applications which support loads greater than 500 Newtons per connection, quick-mount connectors with tool-less assembly for more than 40% time savings in installation, adjustable angle connectors for tilt adjustments 5 to 60 degrees, integrated bonding connectors with electrical grounding lugs to meet NEC 690, hidden fastener connectors for clean aesthetic, sliding connectors for thermal expansion in large arrays, more than 50 meters, high-wind region connectors for vibration resistance, and custom curved profile connectors for BIPV, carport connectors, and floating solar pontoon with connectors.

The placement of bolt holes to within ±0.005 inches allows for proper alignment to standardized extrusion T-slots and eliminates field modifications. This results in installation time being 20-30% more efficient when compared to custom drilled connections. Having flat mating surfaces to within 0.010 inches ensures uniform contact and even load distribution. This prevents stress concentrating and possible connection failure. This failure could happen under wind load of 1200 to 2400 Pascal which is typical. Properly dimensioned threads in the ISO metric system provide fastener engagement that is reliable and bolt pull-out strength of more than 2000 N which prevents connection loosening due to vibration and thermal cycling. Engineered strategic rib patterns provide connection reinforcement that improves stiffness 30 to 50% and reduces connector weight and material cost at the same time. Anodized quality finishes ensure the connection remains protected against corrosion and UV radiation, extreme temperatures, and moisture as well as salt spray found in coastal areas. Superior manufacturing allows for solar arrays to maintain reliable structural joining in residential rooftop, commercial ground-mount, and utility-scale photovoltaic installations while serving for 25 years. This is with low assembly costs, easy installation, and maintenance-free operation.
