HORIZON Above Parking Lots

HORIZON makes it possible to use large areas twice.

HORIZON is ideally suited for solar energy production over parking areas (carports). In comparison with normal carport systems, HORIZON ofers important advantages:

  • its foldable solar roof protects vehicles, people and goods from the sun
  • it is completely retractable, which ensures there are no restrictions in maintenance work on the parking area and also protects the roof from acts of vandalism during the night
  • designers and architects are free to choose and customize the material, form and color of the supporting structure
  • with the same investment, compared to conventional carports, HORIZON offers double performance (kW/m2) while cutting material requirements in half
  • no restrictions on either cars or trucks thanks to the wide gaps between supporting columns of 25m x 17m and the clear height of 4.3m
  • parking area remains free of ice as temporary retraction of the foldable solar roof permits exposure to the sun
  • snow clearance can be accomplished without hindrance with a retracted solar roof
  • the supporting structure contains a charging point for electric vehicles, which can be integrated without any further engineering works

HORIZON over Waste Water Treatment Plants

Waste water treatment plants use vast amounts of electricity. The power needed can be produced on the spot, dramatically raising energy efficiency.

HORIZON presents the ideal solution for installations over settling basins:

  • no restrictions on circulation routes across the plant thanks to light construction and slim columns set wide apart
  • no obstacles to maintenance works on the waste water treatment plant and on machinery such as scrapers and aerators thanks to the retractable roof
  • roofing during the post-clarifying phase reduces algae production – this, in turn, lowers maintenance requirements
  • 100% self-sufficiency: where electricity requirements are consistent, off-grid self-sufficiency of up to 100% is possible
  • HORIZON is specifically designed to allow for unrestricted freedom of movement between settling basins

dhp technology spearheads a research project on the durability of solar installations within the operational context of waste water treatment plants with a pilot project in the Swiss Canton of Grisons and in collaboration with its partners reech GmbH, SUPSI, EAWAG, Hunziker Betatech, SGK.


Foldable Power Plant

Foldable Power Plant

HORIZON – the flexible solar folding roof by dhp technology AG

HORIZON is a solar folding roof system which turn parking lots and logistics areas into electric power plants. HORIZON unfolds when the sun shines and automatically retracts into a storage unit afterwards.

With its lightweight construction consisting of supporting columns set wide apart at 17 x 25 meters at a height of five meters, HORIZON allows for unrestricted freedom of movement underneath the roof.

HORIZON’s patented system protects itself from weather, dirt and vandalism and it has proven itself technically, esthetically and economically.

Five Sound Reasons

HORIZON reinvents solar energy power plants

  • HORIZON produces power right where it is used: in industrial quarters, shopping malls, residential areas.
  • Thanks to HORIZON, the solar energy plant does not take up any space as it is mounted above areas already developed, such as parking lots.
  • Space, a valuable and limited resource, is thus protected and infrastrucutre costs are kept to a minimum.
  • HORIZON is scalable – a basic unit measures 50 meters in length and 17 meters in width and this can be extended freely.
  • HORIZON allows for customized design, meaning architects and builders can integrate it into their projects seamlessly.

dhp technology goes Korea

Korea is an ideal HORIZON country. 50 million people living on one area, 2.5 times the area of Switzerland. So densely populated, that the double use of areas for solar power production is simply a perfect solution. For this reason we traveled to Korea to the energy trade fair BIXPO to exhibit the HORIZON system together with our Korean partner Hanil Co., Ltd and to sign a Memorandum of Understanding. This will pave the way for our further cooperation with Hanil. Our market entry in Korea is accompanied and supported by Swiss Global Enterprise (formerly Osec). We would like to thank to S-GE for the professional and effective cooperation!
