Simulation of the load tests
july 2022
The simulation models successfully reproduce the results from the load tests!
In parallel to the simulation and optimization of the forming processes, models were created for the load tests on test specimens. These models could now be compared with the results from the tensile, compression and 4-point bending tests. Among other aspects, it was also necessary to assess the spot-welded joints and incorporate them precisely into the simulation model.
Large scale PV module

First large component with NECTO structures
The NECTO panel made of aircraft aluminium
(EN AW 2024 T3) for a caravan prototype measures just under 6m2

Participants at the PV in Motion Conference.
We proposed our PORSCH 911 hood as a support structure for embedded solar cells.
In particular, their cooling and the very torsion-resistant design are outstanding compared to all competitors.

november 2021
We are exhibitor and participation in the Automobil Industrie Leichbaugipfel in Würzburg.“
There we exhibit our PORSCH 911 hood in hybrid design.
It consists of a curved NECTO structure bonded behind a CFRP outer skin. The hood is 60% lighter than the original hood and extremely torsion-resistant.
Finalist @ Enlighten Award
august 2021
We took part in the Altair Enlighten Award 2021 in the Future of Lightweighting category and received the “FINALIST AWARD".
The application was made with our innovative sandwich panels that use NECTO structures
(a further development of MATRIX structures).
Instead of a solar laminate, these NECTO sheets are bonded with a top layer of metal or (fiber composite) plastics.
This allows metal sandwich panels with curved surfaces to be produced.
R&D Project
Photovoltaic thermal collectors
june 2021
The further development of the MATRIX module with additional thermal utilization of the module waste heat achieves over 70% efficiency.
In the innovation project (funded by the NRW Ministry of Economic Affairs) performance tests were carried out on a newly designed MATRIX PV module with additional waste heat extraction (PV/air) in the accredited TestLab Solar Thermal Systems of the Fraunhofer Institute for Solar Energy Systems.
Over 50% of the irradiated energy is converted into heat and at the same time over 20% is converted into electricity by the solar cells.
A positive side effect:
The cooler module increases the electrical efficiency by an additional 4.6% (rel) compared to a module without cooling.
First Solar Plant
september 2020
One of the largest solar park operators in Europe has retrofitted part of its PV park with MATRIX frames.
Instead of gluing the MATRIX frames to PV laminates without standard frames, standard modules with frames were used here and the MATRIX sheet was additionally attached.
The process is intended as a retrofit and will make the solar cells less susceptible to storms and keep them cool. Hundreds of modules were installed in this way.
NECTO structures
up to 25 mm hight
may 2021
With the new adjustable moulding tool, NECTO structures up to 40 mm x 40 mm wide and 25 mm high can be produced.
“With the new tool insert for Boschert automatic punching presses, NECTO structures can be stamped into metal sheets (up to a size of 2 m x 10 m). The NECTO structures can have sizes from 16 mm x 16 mm to 40 mm x 40 mm and can be punched up to 25 mm high.
The new punching tool, which works with a XY table, has the advantage of being able to place the structures in any position very flexibly, compared with the simultaneous punching and forming of a whole series of MATRIX or NECTO structures using a servo press.

Our industrial design is also convincing.
The MATRIX frame not only has many technological advantages, it can also be applied to almost all solar cells and module concepts.
Depending on the dimensions of the MATRIX sheet, particularly light or particularly stable modules can be built, or modules that have a 40 % lower CO2 footprint.
Increased Energy Yield
august 2018
First MATRIX modules on a solar tracker
In a cooperation with the Westphalian University of Applied Sciences in Gelsenkirchen, MATRIX modules demonstrated an increase in energy yield for modules with MATRIX frames compared to PV modules with standard frames.
With irradiation of 700 W/m2 and light wind, the module temperature with MATRIX frames was 2 degrees (steel MATRIX) or 3 degrees (aluminum MATRIX) lower than the reference with standard frames.

@ Fraunhofer Tandem Camp
july 2018
Our innovative PV module concept wins both rounds of the start-up competition "Fraunhofer Tandem Camp", organised by Fraunhofer Ventures.
In cooperation with the Fraunhofer Institute for Solar Energy Systems, small PV modules with MATRIX frames were built and the electrical output was measured under different wind and irradiation conditions.
Because our MATRIX frame acts as a heat sink and colder solar cells deliver more electrical output, MATRIX modules have an advantage. We achieve up to 1.5% more yield compared to the reference, even without any optimisations!

NECTO elements
with insulating effect
april 2022
Only 1 % of the sandwich core of NECTO panels
consists of sheet metal, the rest is stationary air.
A NECTO construction therefore conducts heat poorly from one surface to the other.
If the NECTO openings are sealed with a thin insulating panel, even slightly better insulation
values can be achieved
than with classic caravan structures.

PV modules with MATRIX frames also impressed the jury at the start2grow competition organized by the Dortmund Business Development Agency.
In addition to our production concept and the scientific results achieved so far, the high number of Unique Selling Points (USPs)
was decisive for the excellent ranking.
