FAQ
Frequently asked questions
What is the largest solar panel size that can be built with the PMT EVO 2.0 EW?
In principle, all conventional solar panels on the market 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.
Why can the PMT EVO 2.0 be installed faster than other installation systems?
Very fast assembly is possible with the click connectors. The base system has almost no screw connections, which would require more installation time. In addition, the only tools needed are a tape measure, a chalk line and a torque wrench.
Do the components have to be screwed together?
The standard components of the PMT EVO 2.0 do not need any screws. The base and tower components already provide sufficient stability for the substructure thanks to secure click connections. Cross and ballast braces, middle and end clamps and accessories have screw connections.
Is the lightning current carrying capacity guaranteed?
Our flat roof systems are inherently capable of grounding lightning currents and can therefore be integrated into the building’s lightning protection concept. The solar panels themselves are not capable of conducting lightning, which is why a separate connection must be made. 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 integration of the substructure and the connection between the solar panel blocks must be specified by the lightning protection contractor.
What are the equipotential equalisation specifications with the PMT EVO 2.0 EW?
In principle, there is an equipotential equalisation in the PMT EVO 2.0 substructures. 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.
Can I build over a change of pitch without additional solar panels?
For a roof inclination of up to 1.5°, no additional components are needed. In this situation, it is important for the transition from the base component to the connecting floor profile to run exactly above the high point and can act as a joint. For roof pitches greater than 1.5°, the change of pitch must be built over with the ridge connector.
Can I also plan without Solmont?
The EVO 2.0 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°.
Can I also expand the PMT EVO 2.0 EW in one direction?
Yes. One option is to add a single solar panel at the end of a row of solar panels in the rail direction using a south-facing substructure. Another option is to add a single solar panel in the solar panel direction as well at the end of the row or in the field. However, this single east or west solar panel will need a special back wall and a special EW main floor profile to allow for proper positioning of the back wall tower. This is special material that must be requested separately and is correspondingly more time-consuming and costly to procure.
Why do I need more ballast for smaller roofs than for larger ones?
In general, every building must be analysed separately. Even the basic shape (length, width and height ratios) of buildings influences 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.
Which ballast stones are required?
In principle, our flat roof systems can be secured using any conventional ballast stones. Please note however that our software PMT Plan uses 15-kg ballast stones, measuring of 40 x 40 x 4 cm, by default. Some of the components, such as the side covers and middle and end ballast clamps, are also adjusted to this size and work with these ballast stones without restriction. Please note that ballast stones that differ from these dimensions 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.
If you would like to adjust the ballast stones, we kindly ask that you include that information when your send us the details of your project, so that this can be planned for appropriately. From the planning perspective, we can save the weight of each stone and the matching dimensions in our planning software.

From the planning perspective, we can save the weight of each stone and the matching dimensions in our planning software.
How many ballast stones are required, and where do I position them?
The quantity and locations of the ballast stones to be positioned are calculated by our planning software and output with the ballast plan. Important considerations include the actual number and the matching colour code. The values V and A indicated in the background can be ignored. Standard ballast stones are 40 x 40 x 4 cm and 15 kg. If another ballast stone is used, please inform us of this before the project planning so that we can correctly calculate the ballast.
Does a change in the ballast stones have an effect on the statics?
Yes. Changes to the ballast stones often have an effect on the statics, since the total load on the roof can be reduced or increased.
Example: 17 kg is needed for the ballast of an area. If a 15-kg stone has been stored during planning, two stones (i.e. a total of 30 kg) will be output for this area. If a 17-kg stone is stored in the calculation, only one stone will be output for this area.

Are ballast clamps absolutely necessary?
Because wind, snow and maintenance work can make the ballast stones slip from the main floor profiles, we recommend securing them in the vulnerable edge and corner areas. This should be coordinated 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.
Will a change in the connecting floor profile have an effect on the ballast?
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 increases. Important: If the solar arrays exceed 20.0 x 20.0 metres, they must be readjusted. This means a change in the ballast.
Are there specific roof membranes that the PMT EVO 2.0 cannot be mounted on?
In principle, our flat roof systems can be mounted on any type of insulation and on PVC, FPO/TPO, bitumen, concrete and gravel. It is also possible to install the substructure on green roofs. PMT must verify that the maximum compressive strength of the insulation is not exceeded.
In certain cases, the EVO systems can also be used on trapezoidal sheets. In order to check the feasibility beforehand, we would ask that you contact your PMT sales representative in advance.

Can the PMT EVO 2.0 EW be installed on green roofs?
Yes. We differentiate here between three variants:
- 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)
Why does the PMT EVO 2.0 EW cost much less than the south system?
The difference in price per solar panel is due to the use of materials. The amount of material being used is 1.5 to 1.7 times greater in the PMT EVO 2.0 S variant than in the east-west system.
Can the system be attached to a cable safety system?
In general, it is not permitted to attach any objects to an existing cable safety system. This system cannot withstand the static load of the system and is only designed for the safety of the installers. We offer special mechanical attachment points for the system, whose placement can be planned by the software.
