Guojian Steel Co., Ltd. independently manufactures floating PV mounting systems specifically designed for "fishery-solar complementary" projects. These systems enable the simultaneous operation of surface-level solar power generation and underwater aquaculture, addressing industry challenges associated with the single-purpose use of water bodies and low economic output. Featuring a scientifically engineered structure, the mounts offer simple, flexible installation and compatibility with various module layout configurations; they are also made from eco-friendly, recyclable materials. With extensive expertise in PV mounting manufacturing and robust in-house production capabilities, we offer rapid supply responses and support for customized project requirements. Our products ensure structural stability and reliability, balancing power generation safety with aquaculture productivity to help clients efficiently implement floating PV projects while reducing overall construction costs.

Advantage |
Brief Description |
|
"Fishery-Solar Complementarity": Dual land use, doubled aquatic output value |
Suitable for fish ponds, lakes, and reservoirs; generates power above water while farming below, maximizing water resource utility and increasing revenue |
|
Simple and rapid installation, shortened construction period |
Modular, weld-free, quick-assembly design with standardized components; simple operation saves labor and accelerates construction progress |
|
High module compatibility, adaptable to various layouts |
Compatible with monocrystalline and polycrystalline PV panels; supports horizontal, vertical, and staggered array layouts, flexibly adapting to diverse water-based projects |
|
Dual anti-corrosion options (Hot-dip Galvanized / Zn-Al-Mg), long-lasting durability |
Two anti-corrosion processes available; resistant to moisture, salt, and alkali corrosion; service life ≥25 years with low O&M costs |
|
High wind and wave resistance, stable structure |
High-strength steel combined with a locking wind-resistant structure; withstands strong winds and currents, preventing loosening, noise, or overturning |
|
Direct-from-factory stock; bulk customization available |
In-house production lines; rapid shipping from stock; supports non-standard customization based on water body conditions and module specifications |
Corrosion-resistant materials: Options include hot-dip galvanized or Zinc-Aluminum-Magnesium profiles; resistant to moisture, salt, and alkali corrosion; designed service life ≥ 25 years
Wind load resistance: Optimized wind-resistant structure withstands wind speeds of 60m/s; remains stable and secure against tipping or loosening in strong winds and waves
Module compatibility: Compatible with monocrystalline and polycrystalline PV panels; supports various landscape/portrait layouts; uses standardized, universal accessories
Installation method: Weld-free, modular quick-assembly; includes waterproof sealing gaskets; protects the base surface and prevents water seepage
Production specifications: Factory-standardized cold-roll forming; supports custom dimensions; large-volume stock available for direct shipment
