Water-draining clamp for solar panels


Gujarat-based Prasham Greens has designed water-draining clamps to remove water accumulating on the edges of the solar panels after rains or water-based cleaning sessions.

Water settling at the edges of the panel leads to the accumulation of mud and dirt. If this dirty water is stagnant for long periods, it leads to the formation of hotspots, scaling, and shadowing effects, reducing the panel’s life and power generation.

Prasham’s water-draining clamps can be easily fitted to the frame of the panel to drain the accumulated water and prevent the soiling effect. The company claims its water-draining clamps can improve power generation by 2-10%.

The clamps are made of an ABS-based composite material for high tensile strength and high resistance to physical impacts and chemical corrosion. These are cost-effective, non-toxic, and harmless when recycled.

“Only ABS material is not enough to sustain for a long period in sunlight as it gets brittle. So, we add four types of different chemicals to improve its lifespan to around 10 to 12 years,” Jainam Shah, CEO of Prasham Greens, told pv magazine.

The clamps are available in sizes suitable for 35 mm and 40mm PV panel frames.
