Description
IntegraRack IR WaterBallast Tank – 105 Gallon Solar Ballast Water Storage Bladder
The IntegraRack IR WaterBallast Tank provides a practical solution for adding ballast weight to compatible BallastRack solar panel mounting systems. Featuring a 105-gallon water storage capacity, this flexible PVC bladder delivers up to 875 pounds of ballast weight when filled. Additionally, it can serve as an emergency water storage container when used according to manufacturer guidelines.
Designed for residential, commercial, and off-grid solar installations, the WaterBallast Tank offers an alternative to conventional concrete ballast materials. Its compact shipping dimensions also make transportation and storage convenient before installation.
Key Features and Benefits
105-Gallon Water Storage Capacity
Each IntegraRack WaterBallast Tank holds up to 105 gallons of water. Once filled, the bladder provides approximately 875 pounds of ballast weight, helping stabilize compatible solar mounting structures when installed according to approved engineering requirements.
Dual-Purpose Ballast and Water Storage
The tank provides two useful functions in one product. First, it supplies ballast weight for solar mounting installations. Second, the stored water may serve as an emergency water reserve for appropriate non-potable applications. However, drinking-water suitability must be verified separately.
Compatible with BallastRack Frames
The IR WaterBallast Tank is designed for use with IntegraRack BallastRack mounting frames. According to the manufacturer, one water bladder is required for each installed solar panel. Therefore, installers can determine the required tank quantity based on the number of modules in the array.
Flexible PVC Construction
Manufactured from PVC material with a black finish, the flexible bladder provides a convenient alternative to transporting heavy concrete ballast. Moreover, its lightweight empty design simplifies handling before filling at the installation site.
Multiple Installation Configurations
The WaterBallast Tank can be used in combination with compatible IntegraRack EarthBallast kits. Alternatively, the manufacturer describes installations using treated 2×4 lumber spanning the base tubes of each BallastRack frame. All configurations must follow applicable manufacturer instructions and engineering requirements.

Installation and Ballast Requirements
Proper ballast installation is essential for maintaining solar array stability. Before installation, confirm the required ballast weight, mounting configuration, and structural capacity for the project. Additionally, consider local wind loads, snow loads, ground conditions, and applicable building codes.
Installers should follow IntegraRack’s current instructions for positioning, supporting, filling, and securing the water bladder. Furthermore, account for potential freezing temperatures, water leakage, and long-term maintenance when planning the installation.
Important: The stated 875-pound ballast weight applies when the tank is filled. Actual ballast requirements depend on site conditions and engineering specifications. The manufacturer has not established potable-water suitability in the supplied specifications.
