PV Mid Clamp / End Clamp for Solar Panel Mounting
Overview
PV mid clamps secure two adjacent solar modules, while end clamps hold the outermost modules of an array. Together with rails and bolts, they are core fastening parts for rooftop, ground-mount and carport PV racking. Made from extruded 6005/6063 aluminum alloy with anodized finish, they offer good weather and corrosion resistance. They fit common module frame heights such as 30/35/40/45mm, come in silver or black, and support OEM customization for installers, distributors and racking manufacturers.

PV Mid Clamp / End Clamp for Solar Panel Mounting - Module Compatibility
Select compatible mid and end clamps based on solar module frame thickness, mounting rail design and fastening method to ensure proper fit and secure installation.
Solar Module Frame Thickness
Select the clamp height according to the actual aluminum frame thickness to avoid improper fit.
Clamp Installation Position
Mid clamps are used between adjacent modules, while end clamps are installed at the outer edges of the array.
Rail Compatibility
Confirm the rail slot profile, width, bolt size and fastening method to ensure compatibility.
Module Clamping Zone
The contact position and clamping area must follow the module manufacturer's installation instructions to avoid damaging the frame or glass.
Corrosion Protection
Select an appropriate surface finish for the operating environment and confirm the required coating or anodizing specifications.
Structural Load Requirements
Wind loads, snow loads, clamp quantity and installation positions should be determined by the applicable mounting-system design and project requirements, rather than appearance alone.

PV Mid Clamp / End Clamp for Solar Panel Mounting - FAQ
How are the products packed and shipped for export?
They are packed in inner bags and cartons, with pallets available. Sea freight, LCL and express samples are supported, with FOB, CIF and other terms.
What is your minimum order quantity?
Standard items support small trial orders, while custom items depend on tooling and production requirements. Contact us for a specific quote.
Can you provide test reports or certifications?
We can provide material, dimensional and salt spray reports on request and cooperate with third-party testing. If your market requires specific certification, please tell us in advance so we can assess feasibility.
Do you supply matching bolts and nuts?
Yes, we can supply complete sets with M8 T-bolts, hex bolts, square nuts and washers. Please state your rail model and required accessories when inquiring.
Can color, length and logo be customized?
Yes. Silver or black color, length, hole position, logo marking and packaging can be customized, depending on quantity and process.
Are the clamps made of aluminum or stainless steel?
The clamp body is anodized aluminum alloy, supplied with stainless steel bolts. Please ask us if you need an all-stainless option.
How do I choose the clamp height?
Clamp height must match the module frame height, commonly 30, 35, 40 or 45mm. Send the module model or frame drawing and we will help confirm.
What is the difference between a PV mid clamp and an end clamp?
A mid clamp sits between two adjacent modules and holds both frames, while an end clamp sits at the outer edge of the array and holds one module. They are normally used together.
