Solar Roof Tiles

A Solar-Hybrid-Module with outstanding aesthetics

The Solar Roof Tiles by paXos retain the aesthetics of a conventional roof. The incoming sunlight is converted directly into electricity. In combination with a battery storage system, you can also use the self-produced electricity at times when the sun is not shining. If you additionally connect our Solar Roof Tiles with a heat pump, you can provide heat for your house even more efficiently.

The Solar Roof Tile-Mild Hybrid 14.5W (SDP-MH 14.5W) is a building-integrated, monocrystalline photovoltaic module (BiPV). It has similar dimensions, weight and appearance to a conventional roof tile. It can be installed by roofers you trust. Please contact us for further information on the method.

setup of the Solar Roof tile-mild hybrid 14.5W (SDP-MH 14.5W)

The design of the Solar Roof Tile-Mild Hybrid is based on the intensive study of the roof systems used in Germany. It improves performance points as well as production and installation. We are always in close professional exchange with craftsmen and experts to realize a successful product. It has been shown that a functional structure of the SDP-MH meets our requirements without restrictions. Currently, the SDP-MH consists of two main components, the glass package and the housing.

Photovoltaic Module (Glass Package)

We use a glass-glass design for our SDP-MH 14.5W. This leads to a very high mechanical strength, which is even higher than that of classic modules due to the small format. It is even possible to walk on the solar roof tiles for installation purposes. In addition, the glass package is "hermetically" sealed with a diffusion-tight edge sealing. Thanks to this technology, which comes from the insulating glass sector, the solar cells are protected against moisture for several decades. This significantly increases their service life compared to conventional solar modules.

Housing

The housing is made of a high-quality aluminum alloy using a laser punching process. An optimal corrosion protection is generated by a special KTL coating of all housing parts. The final powder coating creates the aesthetic coloring. The mounting on the roof batten is realized by two high-strength stainless steel screws, the protection against storm suction by two wood screws positioned offset.

During assembly, the glass-glass module is inserted into the housing and thus mounted in a movable manner. The covering of the outer glass area by the enclosing housing serves as additional glass edge protection. The combination of these two main components leads to an aesthetic, durable and highly efficient solar roof tile.

durability

The SDP-MH 14.5W IS 10 TIMES MORE RESISTANT TO HAIL impact THAN THE STANDARD REQUIRES.

In the course of the design and safety certification, an extended test for hail impact resistance according to VKF was carried out.

Thereby the SDP-MH 14.5W achieved 10 times the resistance compared to the required minimum according to IEC.

Hail impact test stand

Comparison ice ball diameter

Minimum requirement / Tested requirement

The minimum requirement according to IEC provides for the bombardment of a solar module with an ice ball with a diameter of 25 mm. The SDP-MH 14.5W successfully passed the test with a 45 mm diameter ice ball without any glass breakage or loss of power. The tested ice ball diameter is comparable to that of a golf ball.

Comparison ice ball weight

Minimum requirement / Tested requirement

The standard ice ball has a weight of 7.5 g. The SDP-MH 14.5W was shot with an ice ball weighing 43.9 g. The weight is also comparable to a golf ball.

Comparison ice ball speed

Minimum requirement / Tested requirement

The standard ice ball is shot at a speed of 23 m/s (82.8 km/h) onto the module. The SDP-MH 14.5W was shot at a speed of 30.7 m/s (110.52 km/h) without sustaining any damage.

Comparison ice ball impact energy

Minimum requirement / Tested requirement

Increasing the diameter as well as the speed of the ice ball leads to a 10 times higher impact energy on the solar module. The solar module SDP-MH 14.5W has withstood this massive impact without any optical damage to the glass module. In addition, there was no drop in performance, so that a hail impact resistance class of HW4 was confirmed for the glass module according to VKF.

systemic ADVANTAGES

The inconspicuous integration of a high-performance 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 design, there are further advantages due to the entire roof system. These include the preservation of the aesthetics. In addition, there is no need for double roofing compared to elevated modules.

Patented movability of the glass module

The main feature of the system is the movable bearing of the glass module of the SDP-MH 14.5W. Since this is not glued as in other systems, the patented slidability of the glass module offers the possibility to access the inner workings of the SDP while it is already installed.

Easy removal and insertion of the SDP-MH into the roof

After the glass package has been pushed up, only the screws for holding and securing against storm suction have to be loosened. Then the single SDP-MH can be pulled out of the roof by the frame without having to remove the entire roof. The SDP-MH can be inserted again in the same way and secured against storm suction. Traditional clip solutions, on the other hand, cause problems in placing the storm suction clips in the already installed roof.

Separation of the work steps "roofing" and "coupling the electrical connections"

The roofing and connection of the electrical components are independent of each other. Therefore, the roof can first be covered by a qualified roofer and then connected by a trained solar technician. In addition, a revision is easy to carry out.

Besides the glass module, the separate housing is another systemic advantage. The flexible connection ensures freedom during installation and exchangeability of individual modules. Furthermore, the rear ventilation is integrated directly into the housing. Stable and durable materials ensure that your house is protected. The SDP-MH is also protected against storm suction by the housing. In addition to row roofing, offset roofing is also possible.

Integrated air duct for rear ventilation

A cavity is integrated into the housing between the two openings, front to bottom and back to top. When several SDP-MH overlap, an air duct is formed. By natural convection, the cooler air rises to the top when warming up.

Cooling of the solar cells

The air duct provides rear ventilation and cooling of the solar cells. This increases the efficiency of electricity generation.

Longer service life of the solar modules

The temperature of the solar cells is reduced by the rear ventilation. This is accompanied by an increase in service life and degradation is significantly minimized.

Making use of waste heat from the solar cells

With the help of an air-water heat pump, the air heated by the solar cells can be sucked off centrally in the ridge and made usable. The warmed up air provides for a more efficient operation of the heat pump, so that less power is needed for the supply of heat.

Variants

The use of modern cell types and different powder coatings contributes to an exceptionally wide range of colors. In this way you can choose between four colors of the SDP-MH on your roof. Do you prefer the classic black look or terracotta? Or something more fancy like a blue or green roof? We make it possible that the color does not set you any limits when choosing your solar system!

Highly efficient monocrystalline PERC solar cells are used for the SDP-MH 14.5W. These are brought into an optimal format, so that a high power density is achieved with outstanding aesthetics. Due to an intelligent interconnection, the current intensity remains low, which reduces the electrical losses within the module. A further advantage of the interconnection is a better shade compensation compared to common solar systems, which leads to higher annual power yields.
