The Renusol ECO Ballast Set FS 2100mm (Part No: R-520502) is a complete ballast mounting solution for securing Renusol flat-roof solar PV systems without penetrating the roof covering. Designed for use with Renusol's ECO flat-roof mounting range, the set combines aluminium ballast rails, stainless steel fixings, and EPDM protection pads to distribute weight safely across the roof surface while keeping the waterproofing layer fully intact.
Each set is supplied complete and ready to install, and Renusol can provide a detailed wind loading report on request, showing the exact amount of ballast required per module based on site-specific conditions such as building height, location and roof exposure.

Materials
Please Note: This ballast set does not include a calculated ballast weight for your installation. Renusol can provide a detailed wind loading report showing the ballast required per module — contact Renusol's UK technical support team with your installation and site details before finalising ballast quantities.
Penetration-Free Installation
The ballast system secures the mounting structure using weight alone, avoiding any need to penetrate the roof's waterproof membrane — protecting the integrity of the roof covering.
Aluminium Ballast Rails
Each set includes 2 aluminium ballast rails measuring 2100 x 40 x 40mm, providing a lightweight yet strong platform for ballast weight.
Stainless Steel Fixings Included
Comes complete with stainless steel cable ties and self-drilling screws (4.8 x 19mm, A2), securing the rail assembly without introducing corrosion-prone components.
EPDM Roof Protection Pads
Two EPDM roof protection pads (500 x 40 x 11mm) are included to cushion and protect the roof surface beneath the ballast rails from point loading and abrasion.
Custom Wind Loading Reports Available
Renusol can produce a site-specific wind loading report showing the exact ballast weight required per module, accounting for building height, location and exposure.
Compatible with Optional Ballast Trays
Ballast trays (Part No: R-520501) can be added to the design where a higher ballast weight is needed for a particular site.

Does this ballast set penetrate the roof?
No. The ECO Ballast Set is designed to secure the mounting structure using weight alone, without penetrating the roof's waterproof membrane.
What does the set include?
Each set includes 2 aluminium ballast rails (2100mm), 2 stainless steel cable ties, 2 self-drilling screws, and 2 EPDM roof protection pads.
How much ballast weight do I need for my installation?
This set does not include a pre-calculated ballast weight. Renusol can provide a site-specific wind loading report — contact their UK technical support team with your installation and site details.
Can I add more ballast if my site needs it?
Yes. Optional ballast trays (Part No: R-520501) can be added to the design to accommodate a higher ballast weight where required.
What are the EPDM pads for?
The EPDM roof protection pads cushion the roof surface beneath the ballast rails, protecting it from point loading and abrasion.
