Building a photovoltaic (PV) project is more than just installing solar panels—it’s about ensuring long-term efficiency, reliability, and financial success. A well-constructed PV system minimizes downtime, reduces maintenance costs, and maximizes energy output. But how can you be sure your project is built to industry best practices? By conducting thorough construction inspections.
This article highlights key aspects of PV construction that must be checked to guarantee high-quality standards and prevent costly issues down the line.
Why Mounting Quality Matters
The mounting structure is the backbone of your solar installation. Poorly secured modules can shift, leading to misalignment, structural stress, and potential damage from wind, hail, or snow. Ensuring proper mounting techniques is crucial for long-term system stability and performance.
Here are some best practices when using clamps to fix PV modules:
✅ Avoid contact between clamps and the front glass to prevent damage
✅ Ensure clamps don’t cast shadows on the modules, reducing efficiency
✅ Align clamps properly with the frame to prevent stress points
✅ Tighten bolts to the manufacturer’s recommended torque to ensure stability
Cable Management: A Small Detail with a Big Impact
Both DC and AC cables are critical for smooth PV system operation. Poor cable management can lead to power losses, safety risks, and expensive repairs.
🔹 Trench Installation: Before laying cables, ensure a proper sandbed and a debris-free trench to prevent coating damage. Maintain correct distances within circuits and install safety tape to protect cables from accidental damage.
🔹 DC String Cables: Avoid over-tightening module-to-module connections, maintain the minimum bending radius to reduce stress, and shield cables from direct sunlight and sharp edges to prolong their lifespan.
Take Control of Your PV Project’s Success
By verifying construction methods and materials, we help ensure that your PV project delivers maximum energy output and financial returns.
