FAQ
Frequently asked questions
What solar panel dimensions are appropriate?
In general, all conventional solar panels can be used with the PMT EVO 2.0. Our substructure covers solar panel widths of 980–1300 mm and solar panel lengths of 1550–2400 mm.
How can the PMT EVO 2.0 S be mounted so quickly?
Thanks to the click connections, the flat roof systems can be mounted in a very short time. The base system has no screw connections, which take more time during installation. In addition, only the following tools are needed: a tape measure, a chalk line and a torque wrench.
Is it necessary to screw the components together?
In principle, our PMT EVO 2.0 substructures do not need to be screwed together. Thanks to secure click connections, the main components provide enough stability for the substructure. This does not apply to cross and ballast braces, middle and end clamps and accessories, all of which have screw connections.
Is the capacity to carry lightning current guaranteed?
Yes. All PMT EVO 2.0 systems can be integrated into the lightning protection concept of the building thanks to their lightning current carrying capacity. However, a separate connection must be established for the solar panels, because the solar panels themselves do not have lightning current carrying capacity. This can be done with the standard cross braces or the standard lightning protection material in accordance with the specifications of the lightning protection planner. The lightning protection planner must specify the connections between the solar panel blocks and the integration of the substructure.
Can I build over a change of pitch of 2%?
A roof pitch change of 1.5° can be built over without additional components. The prerequisite for this is that the transition from base to connecting floor profile runs exactly above the high point and can act as a joint. For roof pitches of greater than 1.5°, a ridge connector is needed for the change of pitch.
Is is also possible to plan without Solmont?
The EVO 2.0 S can be used on almost all roof coverings (with an inclination of up to 5°) without roof penetrations. We recommend always working with ridge couplings whenever possible. However, there are a few systems with a roof inclination of 2.0° that exhibit thermal movement effects, and there is a much greater number of systems, some with greater inclinations, that do not display this effect. For that reason, we have decided to follow the white paper of the German Solar Association and recommend this connection with roof inclinations starting at 1.0°.
Why is more ballast needed for smaller roofs than for larger ones?
Every building must be analysed separately. Even the basic shape (length, width and height ratios) of buildings has a big influence on what ballast is necessary, because the zone distribution of the roof behaves differently depending on the fundamental geometry. In addition to the height of the building and the inclination of the roof, parameters such as terrain category (proximity to large bodies of water) also play role.
Do I need special ballast stones?
In general, our flat roof systems can be secured using any conventional ballast stones. In our PMT Plan software the standard calculation uses 15-kg ballast stones, measuring 40 x 40 x 4 cm. Some of the components, such as the side covers and middle and end ballast clamps, are also adjusted to these dimensions and can be used with these ballast stones without restriction. Ballast stones that differ from this size can only be attached to the substructure with additional ballast braces, for example. It may not be possible to place ballast stones that are too small on the ballast braces.
When you send us the details of your project, please let us know about adjusting the ballast stones, so that they can be calculated correspondingly. From the planning perspective, we can save the weight of each stone and the matching dimensions in our planning software.

Is there a specific requirement for the distribution of the ballast stones?
Our PMT Plan planning software calculates the number and positioning of the ballast stones to be set down and puts them in the ballast plan. It is important to note the actual number and the matching colour code. The values V and A indicated in the background can be ignored. 15-kg ballast stones measuring 40 x 40 x 4 cm are automatically inserted in PMT Plan. To correctly calculate the ballast, please let us know before the planning phase if another ballast stone is going to be used.
What is the effect on the statics when the number of ballast stones is changed?
Changes to the ballast stones reduce or increase the total load on the roof. This often has an effect on the statics.
Example: 17 kg is needed for the ballast of an area. If a 15-kg stone has been stored during planning, two stones, weighing 30 kg, will be output for this area. If a 17-kg stone is stored in the calculation, correspondingly only one stone will be output for this area.

Do I absolutely need ballast clamps?
Weather and maintenance work can cause the ballast stones to slip from the main floor profiles.
To prevent this from happening, we recommend securing the ballast stones in the vulnerable edge and corner areas. In all areas, this should be discussed with the owner of the building. Because the stability of the substructure can only be maintained with properly positioned stones, the positioning of the ballast stones must be inspected during every maintenance period.

Does the ballast change when the connecting floor profile changes?
Changes are not noticeable between 60 mm and 200 mm or up to 300 mm. However, when using special connectors of 500 mm, the ballast rises.. Important: If the solar arrays exceed the maximum array dimensions of 20.0 x 20.0 metres, they must be readjusted, which would cause a change in the ballast.
Which roof membranes and types of insulation can used for the installation of the PMT EVO 2.0 S?
In principle, our flat roof systems can be mounted on any type of insulation and on PVC, FPO/TPO, bitumen, concrete and gravel. Installation of the substructure is also possible on green roofs. PMT must perform a verification to guarantee the maximum compressive strength of the insulation. In certain cases, the flat roof system can even be used on trapezoidal sheet metal. Please contact your PMT sales representative in advance for an inspection for the implementation.
Are green roofs also suitable for the EVO system?
Yes. There are three different variants for this situation:
- Standard substructure on not-yet-green roof and vegetation
- Standard substructure on roof vegetation with normal ballast
- Raised variant, in which the substructure is screwed onto ballast stones (Multi-Monti)
Are there specifications for equipotential equalisation with our mounting system?
In principle, our aerodynamic substructures provide equipotential equalisation. The system itself is a low-resistance connection (<1 Ω). The solar panels themselves are not low-resistance connections, which is why a separate connection must be established. This can be done with the standard cross braces or with the specified materials from an electrician.
What is the reason for the difference in prices between the PMT EVO 2.0 S and the PMT EVO 2.0 EW?
The amount of material used in the south system is about 1.5 to 1.7 greater than in the east-west variant, which is why the cost for each solar panel is correspondingly higher.
Can the system be attached to a cable safety system?
As a matter of principle, nothing is permitted to be attached to an existing safety cable. It is designed and built exclusively to protect people from falling and therefore cannot withstand the permanent static load of the system. The mechanical attachment points from PMT, which have been planned by our software, are more suitable.
