In time with the sun<br />
Since July 2018, the sewage treatment plant at<br />
Chur (Switzerland) features a very special roof: The<br />
HORIZON foldable solar roof by dhp technology is a<br />
one of its kind worldwide and allows for an intelligent<br />
dual use of industrial sites. Decentralised drives from<br />
NORD DRIVESYSTEMS are used for autonomously<br />
expanding and collapsing the folding roof panels.<br />
Power producer, sun shade, sun worshipper, weather expert and<br />
master in space saving – the HORIZON foldable solar roof by<br />
dhp technology, a Swiss start-up, is a one of its kind worldwide. It is<br />
erected over already used areas and thus allows for intelligent dual<br />
use without needing to cover a single additional square metre with<br />
buildings or restricting the primary use of the area below. This saves<br />
resources such as space and ground in populated areas, makes<br />
large decentralised solar power plants possible where electrical<br />
power is needed, and provides shade for persons, goods and infrastructures.<br />
In this way, car parks turn into charging stations, logistics<br />
spaces into freshness zones, and sewage treatment plants into<br />
power plants.<br />
Solar technology redefined<br />
“The foldable solar roof is a unique solution for generating solar electricity<br />
on infrastructure areas because supporting columns can be<br />
set wide apart”, explains Andreas Hügli, co-founder and co- manager<br />
of dhp technology. “This is possible because we have chosen to opt<br />
for cableway technology, and the flexible and lightweight foldable<br />
roofs can be retracted to a protective position. Thanks to this protective<br />
position, the entire photovoltaic system need not be designed to<br />
withstand extreme weather; instead, we can make the modules lighter<br />
and then protect them against wind, snow, and hail in the garage.”<br />
dhp technology, founded in 2015, made energy history in the<br />
Swiss city of Chur where the world’s first foldable solar roof covering<br />
a sewage treatment plant was commissioned – covering the<br />
Chur sewage treatment plant. On board: intelligent, decentralised<br />
drive technology by NORD DRIVESYSTEMS.<br />
Intelligent drive technology from NORD<br />
With an area of 5,800 m 2 , the foldable solar roof of the Chur sewage<br />
treatment plant covers the pretreatment, secondary (biological)<br />
treatment, and tertiary treatment basins. The 2,120 modules produce<br />
550,000 kWh of electrical power per year – equalling about<br />
20 % of the auxiliary power required by the plant. The foldable solar<br />
roof operates completely autonomously and adapts to ambient<br />
