The solar roof tiles from paXos preserve the aesthetics of a normal house roof. The incident sunlight is converted directly into electricity. In combination with a battery storage system, you can use your self-generated electricity even at times when the sun is not shining. If you additionally combine our solar roof tiles with a heat pump, you can provide heat for your house even more efficiently.

Solar Roof Tile.NRW ‐ Decentralized Power and Heat Supply Made in NRW 

Project partner: TH Cologne

This project is funded by the European Regional Development Fund (ERDF).

As part of the above-mentioned ERDF-funded research project in cooperation with the TH Cologne, the solar roof tile is being further developed and optimized so that it can be mass-produced and used like a conventional roof tile. The focus is on both the individual solar roof tile and the overall system, i.e. the series connection of several solar roof tiles. The performance of the system is being investigated in tests in the laboratory and on roof surfaces.

Solar Roof Tile Mild-Hybrid

The Solar Roof Tile Mild-Hybrid 14.5W (SDP-MH 14.5W) is a building-integrated, monocrystalline photovoltaic (BiPV) module. It is similar in size, weight and appearance to a conventional roof tile. The installation can be done by professionals you trust. For more information about the method, please contact us.  


  • Easy covering of the roof surface
  • High resistance to hail
  • Vertical load capacity up to 150 kg
  • Increased impact resistance to shock loads
  • Fireproof according to VKF

The inconspicuous integration of a powerful solar module into the roof structure is a key argument for using the Solar Roof Tile Mild-Hybrid from paXos. In addition to the functional structure, there are other advantages resulting from the entire roof system. These include the preservation of aesthetics. Furthermore, there is no need for double roofing compared to elevated modules.



In addition to the product benefits, the system integration into the roof is a major bonus. Compared to conventional modules, the following advantages are achieved:

  • Cooling of the solar cells
  • Longer service life of the solar modules due to integrated rear ventilation
  • Easy detachment and insertion of the SDP-MH into the roof surface
  • Separation of the working steps "laying" and "coupling of electrical connections"
  • Movability of the glass module for easy installation and integrated mounting step


In addition to the glass module, the separate housing is another technical system advantage. The flexible connection ensures freedom when laying and interchangeability of individual modules. Furthermore, the rear ventilation is integrated directly into the housing. Stable and very durable materials ensure protection of your house. Securing the SDP-MH against storm suction is also realized via the housing.

If you would like to drive the product forward together with us and lead it to success, then we look forward to hearing from you at:


Solar Beaver Tail

Our development team is already working on another design variant of our Solar Roof Tile. With the Solar Beaver Tail, even historic beaver tail roofing of listed buildings can be equipped with the most modern solar technology in the future. The Solar Beaver Tail can also be additionally connected to a battery storage system and a heat pump to provide even more efficient electricity and heat for your house.

The Solar Beaver Tail has the same features and advantages as the Solar Roof Tile Mild-Hybrid

Currently, the first functional prototypes of the Solar Beaver Tail are being developed. As soon as the production of these prototypes is completed, we will provide further information on this website.

In addition to the Mediterranean version in terracotta, there will also be a version in classic black. 


ACCESSORIES in the solar area



For our solar roof tile we have developed a whole roof system, which allows to cover and connect a solar roof quickly. In doing so, the pipes no longer need to be laid through the apartments into the basement or even through an additional pipe box on the house facade. We make use of the fact that there is a downpipe on each side of the roof, which can also accommodate cables.

Usually the piping/cabling is done through the house - with the corresponding effort and nuisance caused by the work.


Directly under the end tiles, the pipe leads from the collector in the ridge to the downpipe, where the feed pipe also leads away. Skylights and chimneys can be bridged, as well as pans with antenna mast or similar. All pipes are located under the pantiles and are not visible in the normal state.

Instead of a roof downpipe with a diameter of 100 mm, a downpipe with a diameter of 150 mm is used, which combines the supply and discharge of fluid, the power line and the roof surface water line. The downpipe is mounted as a half pipe and soldered like a normal downpipe. Then the lines (fluid, power, etc.) are attached to the webs of the downpipe with quick connectors. Afterwards the half-shells (orifices) can simply be placed on top and pushed down to click into place.



Above a temperature of 25 degrees Celsius, the electrical output of solar cells and thus photovoltaic systems drops. In order to cool these systems for maximum performance even in summer and to increase their longevity, we have developed a cooling chimney that can dissipate excess heat.

  • No absorption of the heat in the heat storage tank of the heating system with solar thermal systems and in summer
  • Feeding a pool or feeding the heat into the ground not always possible
  • Draining of the fluid via an emergency shutdown before the fluid begins to boil
  • Unnecessary heating of the attic floor

SOLUTION AND construction

A cooling system for the thermal fluid of the solar thermal system is installed on the ridge and has the shape and appearance of a house chimney. The cooling system consists of a heat exchanger similar to that of a car radiator (hot fluid is cooled by air flowing through it). Unlike the car radiator, however, the radiator used here is installed flat at the end of the cooling chimney.

In front of it is a fan driven by an electric motor. Between the radiator and the fan are several injection nozzles for spraying water, which is operated by an electromagnetic valve. The water can be taken from the water supply system of the house.

Power electronics are used to control the fan motor and the electromagnetic valve, which in turn are controlled by a temperature sensor and/or by the control of the heating system. Also integrated is a bypass valve for the chimney, if cooling is not required - also controlled.


  • Protection of the solar thermal system
  • No emergency shutdown required due to overheating of the solar thermal system
  • Cool attic at higher outside temperatures
  • In combination with photovoltaic systems a performance gain of the solar cells by cooling is possible
