Short answer
The documents required for solar installation, for rooftop systems up to 25 kW as of October 2026, are the connection application form, ID, a right-of-use document such as a title deed or lease, the unique code or construction permit, and a declaration of no prohibition on activity. In Antalya the application is made on AEDAŞ's LUS platform; in apartment buildings the minutes book copy must be notarized.
Key takeaways
- In Antalya, applications are made on AEDAŞ's LUS platform (since 01.10.2023).
- For systems up to 25 kW, five basic documents are requested; in an apartment building a notarized decision copy is added.
- According to AEDAŞ's 2026 tariff, the application fee for 0-50 kW is 0 TL.
- After the connection approval letter there are 90 days for project approval.
- The connection of a system operated without acceptance can be cut and a 3-year application ban can follow.
If you are thinking of installing solar panels on your roof in Antalya, preparing the list of documents required for solar installation in advance is the step that speeds up the application the most. As of October 2026, for roof and facade systems up to 25 kW, the basic paperwork consists of the application form, ID, a document of ownership or right of use, consumption facility information and a declaration of no prohibition on activity. Below you will find what each document is for and its practical equivalent in Antalya.
Where is the application made?
An unlicensed generation application is made not to EPDK (Turkey's Energy Market Regulatory Authority) but to the regional grid operator. In Antalya, Isparta and Burdur this body is Akdeniz Elektrik Dağıtım A.Ş. (AEDAŞ, the local distribution company). According to AEDAŞ's page, since 01.10.2023 unlicensed generation applications are accepted only through its own LUS platform. In other words, you need to upload most of your paperwork digitally.
Also remember that documents submitted in an electronic application are not returned (regulation amendment dated 14.05.2024). For this reason it matters that documents are scanned legibly, up to date and complete. Missing paperwork can cause the application to be left for the following month's evaluation.
Documents required for solar installation: the basic list up to 25 kW
According to the Annex 1 list in the 25 kW procedures and principles, a consumer applying under the simple procedure prepares the following documents. For the current list, also check the "25 kW and below application documents" page published by AEDAŞ, because the company may update the formats from time to time.
| Document | What it is for | Point to watch |
|---|---|---|
| Connection application form (Annex 4) | The official request for the application | Facility capacity and subscriber information must be consistent |
| Photocopy of ID (document of authority for a legal entity) | Verifies the applicant | Companies need a signature circular or document of authority |
| Title deed, lease agreement or right-of-use document | Shows your right to use the roof | In an apartment building, a copy of the minutes book decision is also needed |
| Unique code (existing facility) or construction permit (new building) | Identifies the consumption point | The subscription must be in the applicant's name |
| Declaration of no prohibition on activity (Annex 2) | Declares that you are not a prohibited person or body | Must be signed and completed in full |
This list is based on Annex 1 as updated by the 04.11.2021 amendment. If one of the documents is missing, no other document makes up for it.
Common requirements for the subscription and net metering
Which consumption the generation will be tied to must be clear from the start. For net metering, the generation and consumption facilities must belong to the same tax identification number; consumption facilities in the same group must be in the same subscriber group. For this reason the meter number, the subscriber's name and the person making the application must all match the same identity.
Under the 25 kW procedure, the system cannot exceed the consumption facility's contract power. Generation and consumption are connected at the same metering point and one application is made for each consumption point. Check your contract power in advance from your bill or your subscription agreement. If your capacity is small, you may need to plan the system small as well.
Tenant, owner and company situations
If you are the property owner, the title deed is sufficient. If you are a tenant, the right to use the roof or permission for a solar installation must be stated clearly in the lease; this topic is also covered in our guide to solar panels for tenants. For companies, trade registry and authority documents are requested. In every case, the person making the application must be the owner of the subscription.
Extra paperwork in apartment buildings and housing complexes
In buildings with more than one user, a notarized copy of the minutes book decision that a solar plant may be installed for the applicant is among the application documents. We could not verify a clear ratio in the official text on the majority with which this decision must be taken. For this reason you need to act together with your manager and legal adviser. You can find the process in more detail in our article on apartment solar plants and the unit owners' decision.
In planned areas, solar systems built for a building's own needs are not subject to a building permit, provided they do not affect the load-bearing system and consent is obtained under the Condominium Law (Kat Mülkiyeti Kanunu). Even so, steps such as an implementation project, a technical responsibility undertaking and permission from the authority are required. In other words, the statement "no permit is needed" does not mean "no permission whatsoever is needed".
Technical documents and roof preparation
Besides the paperwork given to the distribution company, there are also technical documents that support the work on site. These are not a mandatory list in the regulation but preparations expected for a good project:
- Roof photos and dimensions: Whether the roof is tile, sandwich panel, membrane or reinforced concrete flat determines the mounting system.
- Structural assessment: The roof's load-bearing capacity must be assessed by a civil engineer. The distribution company and the municipality may ask for a structural suitability document. Because no clear threshold has been verified on the power above which it is mandatory, we give no figure.
- Single-line diagram and project: Shows the panel layout, inverter, protection devices and the meter connection.
- Equipment datasheets: The catalog for the panel, inverter and, if any, the battery. Main equipment must have been manufactured within the last five years (Art. 37/6, 2026).
In Antalya, tile-roofed villas, flat reinforced concrete apartment roofs and sandwich panel industrial roofs are common. Because mounting and paperwork preparation differ for each, we ask for up-to-date photos of the roof at the survey stage.
The official process and documents after the application
The flow of paperwork does not end once the application is made. Under the 25 kW procedure, for a complete application a positive connection opinion is formed within the first 20 days of the following month and the connection approval letter (çağrı mektubu) is issued. For facilities with a contract power of up to 3 kW, a connection opinion is given directly.
- From the notification of the connection approval letter there are 90 days for project approval. If the period passes, the letter becomes void.
- After project approval, the connection agreement is signed within 15 days.
- Acceptance must be completed within 1 year of the connection agreement.
- After acceptance, the system usage agreement is signed within 3 days.
Running the system without acceptance has serious consequences: the connection can be cut without notice, the equipment must be removed within 60 days and the applicant cannot make a new application for 3 years (14.05.2024 amendment). There is no official figure for the total time from application to connection; that is why we do not tell you "it is finished in so many weeks".
Application and fees
According to AEDAŞ's 2026 tariff, the application fee for 0-50 kW is 0 TL. Between 50-250 kW it is published as 3,970.8 TL including VAT, and between 250 kW-5 MW as 7,942.8 TL. Project approval and acceptance fees are also 0 TL for facilities of 50 kWe and below (EPDK Board Decision 14165-12, from 01.01.2026). Because fees are updated every year, confirm from the AEDAŞ page before applying.
Practical checklist for preparing documents
- Note the subscriber number, unique code and contract power on your latest bill.
- Get an up-to-date, legible copy of the title deed or lease.
- If you live in an apartment building, plan the minutes book decision and the notarized copy early.
- Take photos of the roof from four directions and note its general dimensions.
- Clarify your VAT and financing questions with your accountant; for details, see our article on solar panels and VAT.
- To see all the application steps, read the rooftop solar application guide.

The most common paperwork mistakes in applications
The recurring problems we see on site mostly come not from missing documents but from inconsistency between documents. Even if the documents required for solar installation are complete one by one, the following points can delay the application:
- The subscription is in one person's name, while the application form was filled in under a different person's name.
- The lease says nothing about roof use or system installation, and the landlord's permission remained verbal.
- The planned system capacity is above the consumption facility's contract power.
- In an apartment building, a meeting decision was taken but the notarized copy was not obtained.
- Documents were scanned at low resolution; because documents submitted in an electronic application are not returned, correction becomes difficult.
In villas used as holiday homes in Kaş, Kemer or Belek in Antalya, the subscription often belongs to a facility with no year-round consumption. In such cases the consumption profile and contract power should be checked before applying; this information also affects system size. To see which capacity suits you, you can also use the solar energy calculator.
Conclusion
When the documents required for solar installation are gathered in a single folder, the most frequent sticking points of the application process disappear: ID, ownership or lease right, consumption facility information, the Annex 2 declaration and, in apartment buildings, the notarized decision. Because the legislation changed several times in 2026, always check the current document list on the AEDAŞ LUS portal right before applying.
Frequently asked questions
Which documents are required for solar installation?
For rooftop solar up to 25 kW, the basic documents are: the connection application form, a photocopy of ID, a right-of-use document such as a title deed or lease, the unique code for an existing facility or the construction permit for a new building, and a declaration of no prohibition on activity. In apartment buildings, a notarized copy of the minutes book must also be added. For the current list as of October 2026, check the AEDAŞ page.
Where is a solar application made in Antalya?
In Antalya the application is made to AEDAŞ, the grid operator. According to AEDAŞ, since 01.10.2023 unlicensed generation applications are accepted only through the LUS platform. No direct application is made to EPDK. Because application through e-Devlet (Turkey's e-government portal) has not been verified in official sources, you need to apply through the LUS portal. Application results and the connection approval letter are also followed through the same channel.
Can I apply for a solar plant as a tenant?
If there is a lease showing your right of use, an application can be made, but for a system to be installed on the roof the landlord's written permission is needed and the lease must contain a provision supporting it. The subscription must also be in your name. Putting in writing in advance who keeps the system if you move reduces disputes later. If roof use is not written in the lease, first obtaining a written supplementary protocol from the landlord helps the application proceed smoothly.
Is a unit owners' decision required for solar in an apartment building?
In buildings with more than one user, a notarized copy of the minutes book decision that a solar plant may be installed is among the application documents. We do not give a ratio because the majority with which the decision must be taken could not be verified from the official text. It is recommended to have the meeting decision written clearly and in an implementable way, together with your manager and legal adviser. For this reason, having the document notarized right after the meeting and adding it to the application file is the safest way.
What happens if documents are missing in a solar application?
A missing document can cause the application not to be treated as complete and the evaluation to be left for the next period. Under the 25 kW procedure, for a complete application the positive opinion is formed within the first 20 days of the following month. Because documents uploaded electronically are not returned, checking all of them before uploading is the safest way. For this reason, checking the document list from the start and completing any gaps before applying saves both time and effort.
Is a building permit required for a rooftop solar plant?
In planned areas, solar systems built for a building's own needs that do not affect the load-bearing system are, under certain conditions, not subject to a building permit. However, there are requirements such as a project, a technical responsibility undertaking, permission from the authority and unit owners' consent. Saying "no permission is needed" would be wrong; confirm current practice with your municipality. Remember that even where there is an exemption, the project, technical responsibility and authority permission steps must still be completed.
How much is the solar application fee?
According to AEDAŞ's 2026 tariff, the application fee for 0-50 kW is 0 TL. For 50-250 kW, 3,970.8 TL including VAT, and for 250 kW-5 MW, 7,942.8 TL are published. These figures are updated annually, so check the AEDAŞ unlicensed generation page at the time of application.
