Traditional counterweight foundation for flat roof solar power plant is concrete cement blocks.As a solar industry leader,we found HDPE cavity filled with water is more suitable for flat roof pv mounting structure.The photovoltaic support structure usually includes counterweight foundation, support frame, pressure block, bolts, nuts, washers, grounding wire, etc.The HDPE structure is stable, the construction is simple and convenient, it can be relocated, it has strong wind resistance, and it causes no environmental pollution or noise. The advantage of using high-density polyethylene cavities as counterweights in construction is that it is environmentally friendly and noiseless.

Research and development test
The full range of Foner Solar solar products have passed or carried out TUV, REACH and other relevant certifications, and have been verified by wind tunnel tests, and the wind resistance level can reach 60m/s (for example: Suzhou's historical maximum wind speed does not exceed 28m /s), comprehensively solving the wind resistance level and system safety anxiety that owners are most concerned about.
Product advantages
1.the reuse rate is very high: if the solar matrix needs to be migrated for various reasons, only need to disassemble the solar matrix and discharge the water, and the disassembled materials can be quickly assembled in the new project, improving the reuse rate of materials;
2.cost advantage: thanks to the continuous optimization of material and structural design, the system material cost and installation cost are significantly reduced, and the comprehensive brackets cost is reduced by nearly 30%;
3.high stability: through CPVT,TUV,SGS third-party testing and wind tunnel test, system structure stability is strong.
4.Recycling and reuse:HDPE materials can be recycled after the end of the solar project's 25-year operating cycle, and the residual value can reach 30%, reducing environmental pollution.
