Considerations during system design and installation:
By installing a PV system on or at an existing building the load compatibility, (e.g. snow/wind) up to that point will be
changed. To prevent personal injury and/or material damages it is necessary to have the static calculations of the building
reviewed by a qualified technician. It is also necessary to regard the current regulations, especially NEN6702, NEN7250,
NEN1991-1-1-4 A1 + C2/NB. If the static calculations of the building are not verified, this may result in worst case scenario
of the building collapsing (the supporting construction). The insurer should be consult in the case of architectural changes.
Roofs are always subject to vibrations and movement, which can be caused by activities in the building, such as the
influence of the weather, thermal working or seismic activity, by means of which PV systems can move, shift or sag. In some
cases it may be necessary to attach/anchor the PV system to the roof.
When determining the edge and angle zones of a building, it is necessary to adhere to the current regulations. When the
edge and angle zones are indicated by Esdec, these are the minimum edge and angle zones. Placement of the solar
panels in the edge and angle zones of a building is always at your own risk and is strongly discouraged.
The following subjects, amongst others, must be checked architecturally and o be approved, for instance by a builder:
• The emergent loads caused by the additional weight of the complete PV system on the building.
• The emergent loads caused by the changed geometry of the roof surface on the building.
• The emergent loads caused by the static load of the PV system on the building.
• The emergent loads caused by the dynamic wind pressure and possible accumulation of precipitation on the building
and the PV system.
• The emergent loads during the installation on the building, the roof construction, the roof covering and the insulation.
• The long term compatibility of the insulation and the roof covering at the locations of the supporting structure contact
points of the PV system, resulting from the point pressure.
• The compatibility of the roof covering in combination with the PV system at the location of the contact points.
• The effect of thermal activity between the building and the PV system.
• The effect of possible movement and vibration between the roof and the PV system.
Despite calculations by the employees of Esdec and the software having been carefully executed, no rights can be derived
from these.
Prices of software, catalogues, quotations, etc. are indicative and may change as a result of rising commodity prices or
taxes, for example. Calculations, drawings and the measurements provided in the software, catalogues, quotations, etc. are

All of the systems and services provided by us are subject to our general terms and conditions. Besides the previous
considerations it is required to read our general terms and conditions extensively before proceeding to placement. When
providing an assignment to Esdec you integrally agree with the aforementioned.
