How can I hide objects in output in Overpass Turbo?

Question

I am querying objects with Overpass Turbo, which are restricted to a specific area.
I restrict the query via a relation, in this case a city boundary. Then I map them to the area to query via map_to_area

My problem is that the output always contains the relation itself, but I don't need it. It also is displayed on top of all nodes, so that I cannot see the nodes and ways in overpass turbo, but only the relation (see screenshot below).

Can I somehow suppress the relation in the output (both the map and the JSON)?

Here's my example. I would like to just have the nodes and ways.

[out:json][timeout:25]; ( {{plz=40589}} rel[postal_code="{{plz}}"]; map_to_area; node["power"="generator"]["generator:method"="photovoltaic"](area); way["power"="generator"]["generator:method"="photovoltaic"](area); ); (._;>;); out body; out count;

Accepted Answer

First off - there are no power generators in the area you're searching.

So let's use an adjacent post code.

The problem was the inclusion of the area inside the union using curved brackets:

rel[postal_code=40599];map_to_area;
(
 node[power=generator]["generator:method"=photovoltaic](area);
  way[power=generator]["generator:method"=photovoltaic](area);
);
(._;>;);
out body;
out count;

However these can be removed entirely by amalgamating the objects to search for (nw):

rel[postal_code=40599];map_to_area;
nw[power=generator]["generator:method"=photovoltaic](area);
(._;>;);
out body;
out count;

Answer 2

Just remove the relation from the output set:

[out:json][timeout:25];

  {{plz=40599}}
  rel[postal_code="{{plz}}"];
  map_to_area;
(
  node["power"="generator"]["generator:method"="photovoltaic"](area);
  way["power"="generator"]["generator:method"="photovoltaic"](area);
);
(._;>;);
out body;
out count;

The parentheses are interpreted as the "union" operator: https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Union
