Versatile & Aestethic

Thanks to its lightweight, unbreakable and flexible properties the solar cell foil can be easily applied to or integrated into countless products. The durable foil will supply clean energy for dozens of years.


Building integrated roof tops

HyET Solar’s Powerfoil is an ideal addition to large flat roofs, especially when these roofs are structurally too weak to hold the weight of traditional solar panels. Powerfoil can be attached to the roofing material in a factory and supplied as part of the roofing material on coils. Powerfoil can be made with a range of different back sheets, enabling the application of Powerfoil to almost any roofing material.


The advantages of applying Powerfoil to the roofing material in our customers factory are:

  • Efficient roll to roll application, efficient material usage, efficient labour usage
  • Highest adhesion quality
  • Lowest cost
  • Independent from weather conditions
  • Minimal installation time (=labour) on the rooftop
  • Rooftop installation does not require additional skills/training
  • Ideal for large uninterrupted rooftops


The advantages of applying Powerfoil on the rooftop are:

  • Freedom to apply Powerfoil where needed and possible
  • Flexibility to adjust sizes and workaround obstacles
  • Enables maximum surface coverage, and thus maximum electrical output from available roof area


After the Powerfoil is fitted to the roof the electrical connections need to be established. We use exactly the same connectors as are being used for traditional panels, therefore electrical connection does not require retraining of installation personnel.


Steel building panels

Attaching Powerfoil to steel building panels (roof and siding) may not be an obvious choice at first. At closer inspection it makes a lot of sense.

Steel roof panels are extremely durable, long lasting and weather resistant building materials. Adding Powerfoil as an extra layer does not change any of these characteristics, whereas traditional panels require the drilling of holes.

Apart from the practical, the aesthetics of metal roofing materials are not compromised by Powerfoil, curves remain curves, and ribs remain ribs.
In addition, the Powerfoil can be applied to the metal panel in the factory, this saves expensive labour on the worksite. Because the Powerfoil can be integrated into the metal panel, installation does not require the changing of existing handling practices.


Highly curved surfaces

Powerfoils flexible nature is clearly visible when applied to curved surfaces like corrugated roof panels. Using this combination of materials, it is possible to convert a tiled roof into an electricity generator without changing the appearance of the roof.

HyET Solar has performed successful tests with colouration of the foil. This will enable the market to apply this technology to any roof colour or shape, increasing the market reach and increasing the potential for solar power without changing the appearances of city skylines.


Mobile applications

Powerfoil is also ideally suited for transportation applications. Often in transportation weight is an important factor. At 600 gr/m² (0.12 lbs/sq ft) Powerfoil can be fitted to camper and caravan roofs without significantly changing the (driving) characteristics of the vehicle.

Because the material is flexible it is far less prone to damage from impact then a glass panel. Because the material is not sensitive to partial shading the positioning of the vehicle on the campsite is not limited and placing antennas on a roof do not impose limitations either.


Outlook on other unthought applications?

We are sure we have not thought of all possible applications of HyET Solar Powerfoil, we are convinced we will continue to be surprised by the inventiveness of people finding new applications for this versatile, flexible and lightweight solar product. Please contact us in case you have any ideas to share.
