What is Water Ballast Solar Panel Mount
Instead of using heavy concrete blocks or drilling into the roof membrane, water ballast systems are a non-penetrating method for mounting solar panels on flat roofs, using the weight of water-filled containers. This approach is particularly valued because it avoids creating potential leak points.

1. Lower transport cost: Unlike concrete blocks, the empty tanks are very light, making them easy to transport to the roof and maneuver into position before filling.
2. No Roof Penetration: No drilling or screws into the roof membrane, eliminating the risk of leaks and avoiding voided roof warranties.
3. Flexible Ballast: You can fill each tank partially or fully depending on wind-load requirements, roof zones, and structural limits.
4. Faster installation: Modular design, fewer components, and no curing time make installation quicker than many penetrated or concrete-ballast systems.
5. Reusable and relocatable: Drain the water, move the system, and refill it elsewhere. Ideal for rented buildings or temporary installations.
6. Easy decommissioning – At the end of life, drain and remove the system without patching holes or repairing the roof.
7. Environmentally Friendly: Water is free, and the system can be easily drained for decommissioning, leaving no permanent impact.
8. The biggest advantage is usually non-penetrating installation with adjustable, transport-friendly ballast

We aim to provide our customers with safe, easy install and economical mounting brackets for ground in harsh environments.
As
a professional manufacturer of solar photovoltaic mounting systems, we
understand that proper packaging is essential to ensure product
integrity during transit and storage. Our packaging solutions are
designed to provide maximum protection while considering environmental
sustainability and cost-effectiveness.
We offer three main types of packaging depending on the product type, size, and destination:
1. Steel Pallet (Iron Pallet)
Steel
pallets are primarily used for heavy and large structural components
such as rails, beams, and purlins. These pallets offer high strength and
durability, ensuring that products remain stable and secure during
long-distance transportation and repeated handling.
2. Wooden Pallet
For components and accessories, we use high-quality wooden
pallets. The wood is carefully selected to ensure load-bearing capacity
and resistance to impact. All wooden packaging complies with ISPM 15
standards for international shipments when required.
4. Strapping Belt
Primarily used for packaging steel products. It helps conserve space, enabling a shipping container to accommodate the maximum possible volume of steel.
5. Wooden Case
Custom wooden case is available to ensure components are neatly organized and well-protected. All
packaging is designed to optimize container space, reduce the risk of
damage, and facilitate easy unloading and installation on-site. We are
also happy to customize packaging according to specific customer
requirements or project needs.
Corigy Solar has been focusing on manufacturing and design solar mounting bracket for more than 10 years. Corigy's products have been installed and used in more than 30 countries and regions, with a total installed capacity of more than 8GW. After the construction is completed, all projects are completed by the official acceptance team, and they are currently officially put into operation.
We offer a comprehensive range of solar mounting solutions to meet
1. Ground Mount Systems – For utility-scale and commercial solar farms; 2. Roof Mount Systems – for both tile, metal, and flat roofs;
3. Solar Carports – Maximizing parking space; 4. Balcony PV Mounts – Compact systems for urban residential use;
5. Solar Fencing – Dual-purpose security and energy generation; 6. Mounting Accessories – Rails, clamps, L feet, and hardware

Corigy Solar driven by automation and precision. Our factory is equipped with state-of-the-art automated production lines that ensure efficiency, consistency, and quality across every product we deliver.
We welcome you to become our distributor.
In terms of selection, Corigy is based on the principle of highest quality. The bracket uses high-quality aluminum alloy (6005-T5) and carbon steel (HDG/ZAM) mounting solutions, allowing customers to choose the optimal material for their project requirements and budget.
Aluminum surface uses anode oxidation 12-15mic. Excellent anti-corrosive rust and anti-rust performance ensures its 30-year service life. At the same time, the characteristics of aluminum lightweight reduces the weight of the roof and make it safe and reliable. The maximum wind speed can carry 60m/s, and the snow load capacity is 1.4kn/㎡.
ZAM
(Zinc-Aluminum-Magnesium) is a next-generation coated steel that
delivers exceptional corrosion resistance and self-healing properties.
Under the same coating conditions, ZAM exhibits 10-20 times the
corrosion resistance of ordinary hot-dip galvanizing. ZAM also possesses
self-healing properties. Over time, coating components dissolve around
the cut and punched edges, forming a dense protective film composed of
zinc hydroxide, alkaline zinc chloride, and magnesium hydroxide. This
protective film has low conductivity and significantly inhibits
corrosion on the end face. Because the ZAM coating is very dense and
smooth, its surface hardness (140-160 HV) is 2.5 times that of ordinary
galvanizing (55-65 HV), giving it excellent scratch resistance. It is
suitable for easily scratched or repeatedly rubbed areas during
processing. Furthermore, the ZAM surface treatment does not contain
trivalent or hexavalent chromium ions, meeting international
environmental standards (RoHS), making it an internationally recognized
environmentally friendly product.
All bracket solutions of Corigy are calculated based on the live conditions environment. Corigy's advanced technical team conducted a force analysis of the structure of the building, combined with the layout of the bracket and photovoltaic components to verify the various feasible bracket installation solutions to determine the most efficient, convenient, safe and reliable solution.
Corigy Solar's vision is to become a global leader in the renewable energy industry. Since its inception, the company has provided safe, reliable, and cost-effective photovoltaic mounting solutions for photovoltaic projects of all scales all over the world.
