Benefits of Using PGRM Component Parts

Custom Fit for Precision Installs

Each component is specifically engineered to match PGRM series mounts, ensuring compatibility and ease of integration. This minimizes guesswork during installation and guarantees structural stability.

Scalable Design

Whether you're installing a two-panel system or expanding to six or more, these modular components make it easy to scale your project. Add mid-rails and end-rails as needed to support new modules.

Rugged Outdoor Performance

Constructed with weather-resistant steel and durable finishes, PGRM parts resist corrosion, UV degradation, and mechanical fatigue—ideal for long-term outdoor installations in varied climates across the USA.

Simplified Installation

All PGRM components are designed for tool-friendly assembly, reducing installation time and labor costs. They are compatible with standard tools, allowing installers to complete projects efficiently.

Enhanced Load Distribution

Mid-rails evenly distribute mechanical loads across the array, reducing stress on solar panel frames and minimizing the risk of structural damage over time.

Use Cases

• Residential Solar Systems: Expand your home's solar capacity by adding more modules using compatible mid and end-rails.
• Off-Grid Solar Arrays: Reinforce top-of-pole systems installed in remote or rugged locations with reliable, long-lasting hardware.
• Agricultural Applications: Provide clean energy to farms and irrigation systems using a robust pole-mount setup with easily replaceable parts.
• Commercial Installations: Customize and scale solar panel arrays for remote monitoring systems, communication towers, or power backup systems.

Installation Tips

Always use the correct size rail (35" or 47") that matches your solar panel's frame length.

Ensure the pole cap is securely fitted and sealed to prevent water ingress.

Use appropriate torque specifications when tightening bolts and clamps.

Double-check alignment and spacing before fully securing mid-rails and end-rails.

Perform periodic inspections to ensure rail integrity, especially in high-wind zones.

Frequently Asked Questions

Q: Can I use 35-inch rails with any panel?

A: No, the 35-inch rails are best suited for modules with frame lengths between 38" and 72". For longer panels, use the 47-inch rails.

Q: How many mid-rails do I need?

A: You'll need one mid-rail between each pair of solar panels. For example, a three-panel setup would require two mid-rails.

Q: Are these parts compatible with non-PGRM mounts?

A: These components are specifically designed for PGRM top-of-pole systems. Using them with other mounts may result in improper fit or structural issues.

Q: Do I need special tools to install these components?

A: No, standard hand tools such as socket wrenches and screwdrivers are sufficient.

Q: Are the pole caps included with the main PGRM mount?

A: The primary kit includes one pole cap, but extras like the 70-0300-PGM-B are available for replacement or multi-mount setups.
