Build Your Perfect Off-Grid Rig With Our System Calculator
Visit CalculatorThe Sungold Power Modular & Expandable Ground Mount Brackets are engineered for high-performance solar installations on rooftops, small buildings, open fields, and large-scale solar arrays. Designed to support two solar panels per set (400W–590W each), this heavy-duty system uses S350GD+ZM 0.07-inch steel, providing outstanding load capacity up to 950 lbs and unmatched durability in demanding environments.
With adjustable tilt angles (20°, 25°, 30°, 35°, 40°), these ground mount brackets maximize solar energy production by enhancing bifacial panel output and allowing optimal seasonal angle adjustments. Ideal for residential, commercial, industrial, and off-grid systems, the mount offers superior strength, stability, and long-term reliability.

Heavy-Duty Steel Construction - Built from 0.07-inch S350GD+ZM high-strength steel for exceptional longevity and structural stability.
Adjustable Tilt Angles - Optimize energy production with five installation angles: 20°, 25°, 30°, 35°, and 40°.
Supports Bifacial Solar Panels - Open-back design enhances rear-side light absorption — boosting output by up to 30%.
Expandable Modular Design - Each bracket set fits 2 panels, and multiple sets can combine for larger solar arrays (4, 12, 20+ panels).
Stronger Load-Bearing Capacity - Evenly distributes weight with a load rating of 950 lbs, outperforming typical 330 lb systems.
Wide Compatibility - Ideal for ground installations, flat rooftops, remote sites, agriculture, and commercial solar plants.
Corrosion-Resistant Hardware - Includes high-grade bolts, clamps, and components for long-term outdoor performance.

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
