BiTile Solar Roof
The BiTile solar roof is designed to give solar panels a double function. We use the solar panel to replace roof tiles and to integrate solar energy into the building in an attractive way.
For a good solar roof, it is important that the technical requirements of solar panels are correctly combined with the technical requirements of roof tiles. For solar panels, the NEN7250, the NEN1010 and the Scope 12 guidelines apply. For roofing, the requirements in the NEN6707 and NEN1991 are applicable. Robisol deems it necessary to supplement the standards with additional requirements in the field of fire safety:
- Air volume under the solar panels (Cavity)
- Ventilation per panel (Cooling)
- Fire resistant materials
- And arc detection on inverters
How does it work?
With the BiTile solar roof, the solar panels are actually the roof covering. Unframed solar panels are placed with an overlapping ventilation space so that the solar roof is properly cooled.
The black anodised beams are an important component. They are placed horizontally across the roof and replace the battens. Any unevenness in the sub-roof is corrected with the roof hook.
Rubber supports and glass hooks are placed in the aluminium beam. These ensure that the solar panels are protected and secure.
The solar panels are slid into a beam at the top and secured in the glass hooks at the bottom.
The solar panels are connected laterally with an intermediate post that is fitted with a rubber seal and a secondary drain channel.
Where a solar panel does not fit, a fireproof black-coated Albond sheet is used. This can be delivered to size or cut to size on site around skylights or at roof ends.
In the case of a skylight, a water drain profile is placed under the sill. This ensures that the water from the window flows over the underlying solar panels.
On the sides, an angle line is applied that is also made of Albond. This ensures a neat finish for the end wall. The top and bottom profiles are also made of the same material, so that the whole roof has a uniform appearance.
What fits nicely on your roof?
The BiTile Solar Roof is made for customisation. Prefabrication is desirable for large-scale projects, but being able to easily correct and adapt is an important advantage of the BiTile System, both for new buildings and renovations. It is also nice that the system can be easily dismantled.
When it comes to the correct dimensions, the BiTile System uses fitting panels, top covers and gutter edge profiles. For the width of the roof it is often very neat to place fitting panels. This can be done on both sides, but it is also nice to have the panels staggered. For example, if we place the dapping panel on the left of the first, third and fifth rows, while we place the dapping panel on the right of the second, fourth and sixth rows, we create a sort of half-tile relationship. In the height dimension, additional correction can be made with a row of junction panels, but it is often nicer to use the tolerance included in the top cap and gutter edge profile. For this reason, when choosing a solar module, we ask that you first consider your roof height.
So first of all, we like to consider your roof height when choosing a solar panel. The two solar panels we develop have a height dimension of 684mm (96Wp Small size) or 1008mm (Standard size 320Wp). In addition, the small format solar panel can also be placed standing up, resulting in a height of 854mm (96Wp small format portait).
The number of solar panels above each other should fit comfortably into your roof area. Relative to your roof height (being the eaves to the ridge), we need between 100 and 400mm for a neat fit with standard top and bottom profiles. This also applies to skylights, dormers etc. On the next page you can see how your roof height works out with the panel division.
If your roof height is just wrong, a row of fitting panels can be placed to compensate for the difference in height. In addition, a larger top profile can be supplied or you can choose to place one or more rows of tiles above or below the system. In general, the solar roof is best if we can choose a solar panel that fits well into your roof height so that at least one side of your house can be completely covered.
The BiTile Solar Roof can be extended in an attractive manner with fitting panels. You can opt for an end cap that falls over the edge of the façade, an end cap that ends in a concealed gutter (with fascias or roof tiles) or an adapter panel that connects under a corner rafter. The adjacent photos show some examples.
The working widths of the BiTile solar modules are:
- 96Wp Small size Landscape: 852mm
- 320Wp Standard size: 1688mm
- 96Wp small size portrait: 682mm
The sides of the BiTile System are always fitted with a roof end profile (side over side wall), a side cap (side in concealed gutter) or a fitting panel (side under corner pegs). The width of a roof end profile or side cover is 40 mm. Without infill panels, the system will be 80mm wider than the number of solar panels. With dummy panels, you can keep almost infinitely to the width of your house.
Cut-out and shapes
In the event that your roof is equipped with skylights, dormers, chimneys or corbels, Robisol uses fitting panels. After all, it is not possible to saw solar panels to size. We do ask you to allow approximately 100 mm space on the sides and at the top between the cut-out and the first solar panel. This is necessary to ensure that the solar panels are solidly protected and the roof is properly sealed.
On the underside, please allow approximately 200 mm clearance to the solar panel below. We want to drain the water from the recess over the underlying solar panel. The water drain profile that we use for this purpose lies at the top of the roof plate and brings the water up at an angle over the underlying solar panel. Some space is needed to ensure that the water is drained properly.
Special shapes are no problem with the BiTile System. However, this often requires some extra labour. If your house has cut-outs or slanting corners, we ask you to take sufficient fitting panels into account.
