Gölgeleme analizi panel dizisi için hazırlandı.

Hazırlandı is the past tense passive form of hazırlamak (to prepare).

• hazırla- = prepare
• hazırlan- = be prepared / get prepared
• -dı / -di / -du / -dü = past tense

So hazırlandı means was prepared or sometimes got prepared / became ready, depending on context.

In this sentence, the most natural translation is was prepared:

• Gölgeleme analizi panel dizisi için hazırlandı.
• The shading analysis was prepared for the panel array.

Because it is passive, Turkish does not mention who prepared it.

Because Turkish often leaves the subject out when it is:

• unknown,
• obvious from context,
• or not important.

That is especially common with the passive.

So instead of saying something like Someone prepared the shading analysis for the panel array, Turkish uses the passive:

• Gölgeleme analizi ... hazırlandı
• The shading analysis ... was prepared

The focus is on the result, not on the person who did it.

Gölgeleme analizi is a noun compound.

It is made of:

• gölgeleme = shading / shadowing
• analiz-i = analysis

Together, it means shading analysis or shadow analysis, depending on the context.

This is a very common Turkish pattern. In these compounds:

• the first noun stays in a basic form,
• the second noun usually takes a compound ending, often the 3rd person possessive suffix.

So:

• gölgeleme analizi = shading analysis
• literally something like analysis of shading

This does not mean the same thing as gölgelemenin analizi, which would sound more like the analysis of the shading and is more explicitly possessive.

For the same reason as gölgeleme analizi: it is also a noun compound.

• panel = panel
• dizi-si = series / sequence / array

So panel dizisi means something like:

• panel array
• panel series
• panel string

The exact English choice depends on the technical context.

In Turkish, compounds like this usually require that ending on the second word:

• panel dizisi not
• panel dizi

So this is standard Turkish compound structure.

Turkish uses postpositions, not prepositions, in many cases.

English:

• for the panel array

Turkish:

• panel dizisi için
• literally: the panel array for

So için comes after the noun phrase it belongs to.

This is completely normal in Turkish:

• senin için = for you
• proje için = for the project
• panel dizisi için = for the panel array

Because için takes the noun phrase directly; you do not use the accusative here.

• panel dizisi için = for the panel array

If you said panel dizisini, that -ni would be the accusative case, which is used for a definite direct object:

• Panel dizisini gördüm. = I saw the panel array.

But in this sentence, panel dizisi is not the direct object of the verb. It is part of the phrase with için:

• panel dizisi için = for the panel array

So no accusative is needed.

Because Turkish does not have articles like English a/an and the.

So:

• gölgeleme analizi can mean a shading analysis or the shading analysis
• panel dizisi için can mean for a panel array or for the panel array

The exact meaning comes from context.

That is very normal in Turkish. Learners often want to know whether something is definite or indefinite, but Turkish usually leaves that to context unless another word makes it explicit.

No, Turkish word order is flexible, although the verb usually comes at the end.

This sentence:

• Gölgeleme analizi panel dizisi için hazırlandı.

could also be said as:

• Panel dizisi için gölgeleme analizi hazırlandı.

Both are natural.

The difference is mostly about focus or information flow:

• Gölgeleme analizi ... hazırlandı puts gölgeleme analizi first
• Panel dizisi için ... hazırlandı highlights for the panel array first

So the final verb position is important, but the earlier parts can move around more than in English.

It can be translated either way depending on context.

It comes from:

• gölge = shadow
• gölgeleme = shading / shadowing

In technical or design contexts, shading analysis is often the most natural English translation.
In some other contexts, shadow analysis might also work.

So the Turkish word itself is flexible, and the best English version depends on what kind of panels and analysis are being discussed.

Grammatically, hazırlandı can sometimes mean became ready or got ready, because the passive/reflexive form hazırlanmak can have that meaning in some contexts.

For example:

• Sunum hazırlandı. could mean The presentation was prepared
• in some contexts, it might also suggest The presentation got ready

But in your sentence, because it is about an analysis being made for something:

• Gölgeleme analizi panel dizisi için hazırlandı

the most natural meaning is clearly:

• The shading analysis was prepared for the panel array.

So while the verb can sometimes be slightly broader, here the passive was prepared reading is the best one.
