Retrofitted sun protection thanks to solar power

Retrofitting privacy and sun protection – many building owners shy away from this expense. A family in a terraced corner house in the Swabian district of Neu-Ulm also wanted shading on the upper floor because the rooms were becoming too hot. However, there was no power connection for modernization measures. The intelligent solution: a solar-powered privacy and sun protection system that could be installed without any conversion work.


Elero RolSolar provides more living comfort without costly conversion measures 

The large windows of the terraced corner house with garden ensure a lot of daylight and an open living feeling. As an undesirable side effect, the high solar radiation caused excessive temperatures in the rooms. However, the family did not want to lay any cables for a contemporary privacy and sun protection system. The response was all the more positive when the specialist company Knoll Rollladenbau from Hüttisheim reported on a new solar-powered solution. The drive and control manufacturer elero from Baden-Württemberg had recently launched the RolSolar M-868 DC drive system on the market.  

Convincing product features
Frank Feiler from the Knoll company is enthusiastic about the new possibility: "The RolSolar drive system enables the automation of roller shutters and screens without a power connection and is therefore also ideally suited for subsequent motorisation. The drives feature the proven advantages of elero tubular motors: from the noiseless soft brake to the curtain protection function and two freely definable intermediate positions. These product features combined with the durability and high product quality make RolSolar the top recommendation for our modernisation customers." The family was quickly won over by the solar-powered innovation and commissioned the company Knoll to implement it. 
The zipScreen.2 vertical screens from Roma were chosen as privacy and solar protection. The screen is a perfect fit as it is ideal for large window areas and shading of all-glass corners; RolSolar M20-868 DC was used for the screen motorisation. 

Convenient control system 
The screens are conveniently controlled with the VarioCom-868 6-channel hand-held radio transmitter. The bidirectional transmitter is impressive due to its modern look and ergonomic, user-friendly design. The fitter attached the QuinTec-868 5-channel radio wall transmitter to the wall, which also enables the residents to open and close the door conveniently. Both screens are controlled together or individually with the transmitters. The intelligent radio drive can be easily integrated into the Centero Home smart home solution and then operated by smartphone or tablet. Additional feature: the integration into Centero Home allows an automatic closing and opening command to be programmed, which can also be activated or deactivated on the transmitter.
The modules for the solar motorisation solution have been combined by elero into product bundles which are adapted to different installation situations. Specialists can choose between different types of drives as well as solar panels and batteries in different designs. 

Quick mounting
At the terraced corner house in Elchingen, the zipScreens were first screwed onto the wall and the solar panels optimally placed by the fitter Frank Feiler. The specialist installed both panels on the west-facing zipScreen for optimum light incidence and energy input. The cable was hidden under the matching corner panel. Finally, Feiler programmed the drives on the hand-held radio transmitter and assigned the running direction. He repeated the same for the second transmitter. In this way, the modernisation measure was completed quickly, allowing the building owners to enjoy a pleasant room climate and the comfort of modern privacy and sun protection.
