Solar Water Drain Clamp

A solar water drain clamp (drain clip) is installed at the edges of solar panels to guide rainwater and cleaning water away from the panel surface. It prevents water accumulation, which can cause dirt marks, corrosion, and reduced performance. These clamps are easy to install and suitable for most panel sizes like 30mm, 35mm, and 40mm frames.

A solar water drain clamp is an important accessory designed to improve the efficiency and lifespan of solar panels by preventing water stagnation. During rain or cleaning, water often collects at the lower edges of panels, leading to mud deposits, stains, and hotspot formation, which can reduce power generation.

These clamps are fixed to the panel frame and create a path for water to flow out smoothly, avoiding accumulation and keeping the panel surface clean. They are available in materials like ABS plastic, stainless steel, aluminum, and PVC, offering durability, corrosion resistance, and long life (10–12 years or more).
