Powerful Performance: The Solibro SL2 Module

The SOLIBRO SL2 modules have the highest efficiency among the different thin-film solar cell materials on the market. The first system with SL1 modules and an efficiency on module area of 11.3% was commissioned in the DKA Solar Centre in 2010 and operating with a stable high performance for almost 7 years. The new improved SL2 CIGS material has increased the champion panel efficiency range to 16,94% on a module area of 0.94m².

Yield Advantage with Thin Film

Higher Energy yield is envisaged due to improved long-term-stability in tandem with an improved temperature behaviour. Our modules show an excellent performance at high temperatures due to a temperature coefficient of -0.32%/K and a normal module operating temperature of only 42°C.

Frameless Elegance

Our modules are characterized by their elegant aesthetic appeal thanks to their uniform black surface and their frameless design. Therefore the module is suitable for a wide variety of aesthetically demanding applications while at the same time the advantage of self-cleaning applies. The new slide-in mounting system caters to the aesthetics and provides an even better optical appearance.

Reliability "Made in Germany"

The SOLIBRO SL-2 modules are manufactured in a state-of-the-art factory near Leipzig in Germany. With our new Turnkey-Business Solibro Hi-Tech offers the proven factory concept as a CIGSPowerLine turnkey solution to customers worldwide. The scalable factory concept scores with low production costs and its unique CIGS equipment engineered by Solibro Hi-Tech. For more information visit our website or contact us via email at

Notes on the Data

  1. System Disconnection for Cabling Works

    All arrays at the Solar Centre were disconnected from approximately 2.00pm to 3.00pm on Monday, 9 July 2018 in preparation for the cable between the main switchboard and distribution board being upgraded. Array sites #23-38 remained disconnected while the main feeder cable to these sites was replaced in subsequent days, but all systems were re-connected by early afternoon on Thursday, 12 July 2018.

Q: What mounting techniques are used for holding modules in place at other arrays in our Solar Centre?

A: The typical method for mounting solar modules is to use clamps that grip the sides of the modules and hold them rigidly against a structure (which may be purlins, roof tiles, unistruts or beams). Frameless modules often need custom-designed clamps to ensure the modules are not cracked while being tightened in place, while framed modules can use a wider variety of clamps. Different kinds of attachments are used to suit the modules and their mounting structure, such as feet that can swivel or clamps that conform to different roof profiles. Other than clamping, bolting can also be used to mount modules but this is a less common approach nowadays. Some module manufacturers also provide their own proprietary mounting systems, like the slide-in rails of this array.
