Photovoltaic system design

Sizing and design of PV systems for residential and commercial buildings - from mounting structures to grid connection.

What we take care of

  • 1Site and shading analysis
  • 2Sizing of modules and inverters
  • 3Structural calculation of the mounting structures
  • 4Grid connection and municipal applications
  • 5Support with grants and tax credits
  • 6Acceptance and handover of the system
  • 7ENEA notifications

This list is not complete - describe your project and we will tell you which points are relevant for you.

How we work together

  1. First meeting and inspection of the roof or site.
  2. Site and shading analysis, yield estimate.
  3. Sizing of modules, inverters and optional storage.
  4. Structural check of the roof and mounting structure (wind and snow).
  5. Permits and grid connection request to the operator, dealings with the GSE.
  6. Support during installation, acceptance and documents for incentives.

Time and cost

For a typical system on a house, design and permits usually take a few weeks, depending on the grid operator and the building procedure. The effort depends on system output, shape and condition of the roof, storage and the permits required, for example in protected townscape or landscape areas.

Legal basis

Low-voltage connection is governed by standard CEI 0-21; the application goes through the grid operator and the GSE. The mounting structure is checked according to NTC 2018. Depending on the site, the Provincial Law on Territory and Landscape (L.P. 9/2018) and townscape and landscape protection apply.

Service area

We work throughout Val Venosta - from Resia, Curon and Malles via Prato, Lasa and Silandro to Naturno - in the Burgraviato around Merano and on request throughout South Tyrol. Our office is based in Prato allo Stelvio; site visits are standard for us. We work in German and Italian.

Frequently asked questions

Do I need a permit for a PV system?

On a house a notification is often enough; in protected areas or for ground-mounted systems more is needed. We check this for your site.

Can my roof carry the system?

We check this with a structural calculation of the roof and mounting structure, including wind and snow.

Is a battery storage system worthwhile?

It depends on your consumption profile. We calculate both options.

Who submits the grid connection request?

We do, including dealings with the grid operator and the GSE.

Do you also design systems for businesses?

Yes, for residential and commercial buildings, including large roof or ground-mounted areas.
