1. Safety Risks

Manifestations: Structural instability, overturning, collapse, potentially leading to roof leaks or fires.

Causes: Low-cost solar mounting systems often use thin steel plates, insufficient galvanization, or omit corrosion protection entirely, resulting in inadequate wind and snow load resistance that fails to meet photovoltaic mounting structure design standards.

2. Reduced Power Generation Efficiency

Manifestations: Improper module tilt angles, structural deformation causing shading, or failure of backside shading gain.

Causes: Structural instability leads to failed tilt angle adjustment or loosened mounting bolts, preventing PV modules from maintaining their designed angles.

3. Shortened Service Life

Manifestations: Premature failure within 10-15 years, significantly increased maintenance frequency.

Causes: Material corrosion, poor welding, and loose bolts are more prevalent in low-cost products, reducing overall solar mounting system rigidity.

4. Economic Losses

Manifestation: Maintenance and reinstallation costs far exceed the initial "low-price" savings, reducing overall project ROI.

Causes: Structural failures require shutdowns for repairs or even full support replacement, interrupting power generation revenue.

5. Compliance and Insurance

Manifestation: Difficulty passing project reviews, insurance companies refusing coverage or raising premiums.

Causes: Regulatory bodies and industry associations explicitly require "structural safety as a key tender criterion," while low-cost products often lack corresponding test reports and certifications.

6. Brand Reputation

Manifestation: Declining trust from project owners, hindering future collaborations.

Causes: Safety incidents resulting from low-cost traps create negative industry reputations.
