PV water-draining device with new anti-clogging design - pv magazine International

Portuguese startup Solarud has unveiled the adjacent procreation of its water-draining instrumentality for PV panels with low, sloping inclines. The caller plan avoids clogs caused by soil and dust, successful nano and customized versions that acceptable installations and modules of antithetic sizes.

Portuguese startup Solarud has launched a new mentation of its water-draining device. The caller exemplary tin beryllium clipped to star modules to resoluteness particulate and soiling issues.

After the motorboat of the archetypal instrumentality successful May, the institution listened to lawsuit feedback to make anti-clogging technology.

“In utmost environments similar deserts oregon arid environments with debased humidity, erstwhile the archetypal rainfalls fell, oregon during aboriginal greeting condensation, the instrumentality would get clogged,” António Neves, the co-founder of Solarud, told pv magazine.

Accumulated soiling tin pb to clogging successful residential installations, with the devices requiring cleaning aft a fewer months.

The company's Solarud Nextgen solution features the company’s patented anti-clogging plan to code this issue. It claims vigor gains of 3.5% connected mean with the archetypal device, and expects adjacent amended results with the Nextgen, though it has yet to commencement investigating the design.

The merchandise is besides much adaptable to antithetic module sizes than its predecessor. The archetypal instrumentality worked with framework heights of 30 mm, 35 mm, and 40 mm.

“The caller instrumentality tin accommodate to immoderate measurement betwixt 30 mm and 40 mm. The tabs are nary longer breached [to accommodate to the intended measure] but are alternatively folded. This folding gives them a outpouring effect, thereby adapting to antithetic heights,” said Neves.

The caller instrumentality tin frankincense accommodate to framework heights of 32 mm and 38 mm, which are modular successful the industry. The institution has switched from concern 3D printing to utilizing injection molding for the Nextgen. The power has “increased the accumulation origin by astir 20 times, and has besides allowed for creating much robust devices,” said Neves.

It is offering a six-year warranty for the Nextgen – a four-year betterment connected its predecessor. The caller instrumentality is besides cheaper, and is disposable for bulk purchases, starting astatine 50 units for €99.50 ($96.61), oregon €1.99 per piece, positive VAT and shipping costs. The archetypal instrumentality is nary longer manufactured oregon disposable for purchase.

The institution has besides launched nano and custom-made versions of the device, some featuring the anticlog design. The Solarud Nano, with a basal of little than 10 mm, compared to the Nextgen’s 22 mm, is designed for installations with precise tiny gaps betwixt modules, up to 10 mm.

The Nextgen and the Nano devices tin lone beryllium adapted to frames with thicknesses betwixt 8 mm and 11 mm, but the Solarud Custom tin beryllium made to measure.

“We person been asked for devices with 13 mm and 15 mm thickness, particularly from costumers successful Australia, truthful we decided to make a work of custom-made devices,” explained Neves. “The clients nonstop america the modules’ datasheet, we plan the instrumentality to acceptable the specifications, nonstop the costumers immoderate samples, and if they are satisfied, they tin past bid the devices connected our website.”

Both the nano and customized devices are 3D printed and are disposable for bulk purchases starting astatine €2.49 per unit, positive VAT and shipping costs. The institution develops and produces each the devices successful Portugal and has an planetary lawsuit basal focused successful Europe and Germany, successful particular.
