a) Information concerning the building

You can get a lot of valuable information about the project already at the first telephone contact. Here are the most important questions, summarised as a Checklist:

- Is the property owned or rented?

- If a rental: Is there a written consent from the property owner?

- Is it a detached, semi-detached, terraced or multifamily unit property?

- Cardinal point roof orientation?

- Roof area in square meters?

- How many square meters are not usable due to the presence of skylights or chimneys?

- Does the roof area planned for PV use partially lie in the shadow of trees or buildings?

- Is the building listed?

Topic: Building permit

In most countries and regions, the installation of a PV roof system on a detached single family home does not require a permit. Whether or not a permit is required is defined by the pertinent national and regional building regulations.

It is advisable to consult the regional building regulations and/or to enquire at the pertinent Town Planning Office about obligations concerning displaying notices and/or obtaining permits.

Topic: Historical monuments / Listed buildings / Preservation orders

Listed buildings fundamentally require approval from the pertinent Heritage Preservation Authority; guidelines and leeway for action can differ from one district to the next, so that it is recommended to obtain this information in all cases.
