Photovoltaics in the garden

Make yourself independent of high electricity costs

The statics must be right

The basic prerequisite for the installation of PV systems is that the kit is sufficiently stable. Therefore, check whether the desired kit is designed for the required snow load and a PV system. Calculate approximately 0.15 - 0.35 kN/m² for solar modules and their substructure. For many kits, we offer optional reinforcements for the roof.

Many of our kits are suitable for mounting solar modules for PV systems

Flat roofs with timber cladding and EPDM foil

When installing a PV system on a flat roof made of timber boarding, we recommend using EPDM foil as the roof covering. You can install a PV system on this very stable foil without "roof penetration". The frames of the PV system are secured against storms with paving slabs or curbs, for example.

Gabled or monopitch roofs with roof tiles or sheet steel

Gable or monopitch roofs are available from us with roof battens for the application of roof tiles or steel roof sheets or with roof boarding for the application of roof shingles.

We recommend the "roof battens" variant. There are many pitched roof systems for roof tiles or steel roof sheets that enable the installation of PV systems.

Good to know:

  1. Static calculation

The basic prerequisite for the installation of PV systems is sufficient statics of the kit. Our kits are statically designed for a specific snow load (per square meter). There is a specified snow load for the construction site where your kit from us is installed, which is prescribed for a construction project. You can find out the local snow load from your local building authority or here, for example: https://www.dlubal.com/de/loesungen/online-dienste/schnee-wind-erdbeben-lastzonen

The difference between the snow load of the kit and the specified snow load is the maximum roof load for the solar modules.

Example snow load: Carport Friesland
The snow load of a carport is 1.25 kN/m² and the location-dependent snow load is 0.85 kN/m², for example. You have a reserve of 0.4 kN/m² for the construction of the solar modules. If this reserve is not sufficient, snow load increases can be ordered as an option for many of our kits.

Example snow load increase: Carport Friesland
An optional snow load increase to 2.00 kN/m² can be ordered. The reserve would then be 1.15 kN/m².

1.15 kN/m² Reserve for solar modules and construction

Calculate approximately 0.15 - 0.35 kN/m² for solar modules and their substructure.
This value depends on the construction you have chosen.
