Commercial Drone Solar Panel Inspection in Romania

The EU Framework and Why Most Solar Inspections Land in the “Specific” Category

Romania, like all EU member states, implements EASA’s drone regulation (EU 2019/947). The regulation splits operations into three categories:

• Open – Low‑risk flights with no overflight of uninvolved people, always within visual line of sight (VLOS), and usually below 120 m. Sub‑250 g drones (like a DJI Mini 3 Pro) get some extra freedom, but commercial intent does not exempt you from operator registration or pilot competency rules.
• Specific – Operations that cannot meet all Open‑category limits. Almost every professional solar panel inspection will fall here if you need to fly closer than 30 m (or 5 m in slow mode) to buildings, over partial assembly areas, in urban zones, or if you plan to use autonomous waypoint missions beyond the pilot’s unaided view.
• Certified – Reserved for large drones and high‑risk operations, rarely relevant for typical solar inspections.

This article concentrates on the Specific category because that’s where most Romanian (and EU‑wide) commercial solar work sits.

Step‑by‑Step: Getting Authorised in Romania

1. Drone Operator Registration with AACR

Every commercial drone operator — regardless of drone weight — must register with the Romanian Civil Aeronautical Authority (AACR). You’ll receive an operator registration number that must be affixed to the drone. Registration is done through the EU‑wide portal that AACR administers locally. Even if you already registered in another EU state, a commercial operator with a principal place of business in Romania needs a Romanian registration.

Calibrated note: While some third‑party sources mention ANCOM, drone registration and pilot certification rest with AACR, not the telecom authority. If you’ve encountered conflicting references, the safest path is to go directly to the AACR website and follow its published drone‑operations guidance.

2. Remote Pilot Competency

For Open‑category flights, you’ll need at least an A1/A3 certificate (online theory exam). If your solar inspection can be performed outside urban areas, at a safe distance from uninvolved persons, and strictly within VLOS, A2 certification (additional self‑study and exam) may suffice for heavier drones. In the Specific category, however, AACR will typically require a remote pilot certificate of competency linked to the operational authorisation — often proving completion of a practical training course from a recognised entity or a declaration of proficiency.

3. Operational Authorisation (OA) Under the Specific Category

The core hurdle: you must show that your planned solar inspection mission is safe. In Romania, the path is:

• PDRA (Pre‑Defined Risk Assessment): If your operation fits a published EASA PDRA (for example, flights over controlled ground areas with drones up to 25 kg), you can use a simplified declaration process. Many rooftop solar inspections over private, closed‑off property may fit PDRA‑G01.
• SORA (Specific Operations Risk Assessment): For more complex missions — such as flying over a partly inhabited solar farm near a public road, or using automated pattern flights with a DJI Mavic 3 Thermal — you’ll develop a SORA, submit it to AACR, and negotiate mitigations (e.g., airspace observation, geo‑fencing, pre‑flight inspection protocols). AACR’s acceptance typically arrives as an operational authorisation with defined conditions.
• STS (Standard Scenario): If Romania implements STS‑01 or STS‑02, you may be able to operate under a standard scenario declaration without a separate SORA, provided your drone has the appropriate C class marking. Most DJI drones purchased before 2024 lack this marking, so the authorisation route often remains the practical one until operators transition to class‑marked models.

Disclaimer: The above outlines general possibilities under the EASA framework. AACR’s interpretation, fees, and processing times evolve. Always verify current procedures with AACR directly. This article does not constitute legal or regulatory assurance.

4. Insurance

Commercial drone flights in Romania require liability insurance. While precise minimum coverage is not set in stone by a single EU rule, AACR (and potential clients) will expect at least standard third‑party liability protection appropriate to the aircraft weight and operational risk. Confirming with a Romanian‑licensed aviation insurer is the prudent step.

Beyond Romania: EU Neighbours and Their National Nuances

Operators often work across borders or manage fleets registered in different states. The EU framework provides consistency, but local accents remain.

For EU countries not listed, the Starting point is always the national aviation authority’s application of EASA rules. The table above is a signpost, not a complete compliance checklist. For Vietnam and Mexico, only the local civil aviation authority can give you the precise path; treat EASA comparisons as a conceptual stepping stone, not a direct parallel.

Aircraft Condition, Firmware, and the “Expired Firmware” Question

Search queries from Romanian operators often ask whether flying a drone with expired firmware is legal for solar panel inspections. There is no single Romanian aeronautical regulation that directly bans operation with an old firmware version. However, commercial authorisations under the Specific category typically require the operator to define and follow an aircraft maintenance and airworthiness programme. Logging into DJI Fly and ignoring mandatory updates that patch known flight‑control instabilities could be viewed as a failure of the safety case. In practice:

• A SORA or PDRA submission that lists a firmware version may be checked.
• An incident occurring with outdated firmware could raise negligence questions.
• Insurers may deny claims if the drone was flown outside the manufacturer’s recommended configuration.

We recommend: keep both the drone and its batteries on the latest manufacturer‑released stable firmware, document all updates in your operational log, and consult AACR if your operation specifically requires a legacy version for a validated reason.

If you’d rather not manage the hardware confidence yourself, the Reboot Hub standard eliminates the guesswork. Every unit we ship has undergone a rigorous multi‑point bench test, updated to current firmware, and graded so you know exactly what you’re putting to work.

Volunteer Search and Rescue: A Different Permission

A Romanian operator holding a commercial solar inspection authorisation might want to offer drone support for local search‑and‑rescue (SAR). An existing Specific‑category OA does not automatically extend to volunteer SAR flights. SAR missions often involve flights over populated zones, at night, and beyond VLOS — all of which fall outside a standard inspection SORA. The legal route is:

• Approach AACR with a defined concept of operations covering the expected SAR parameters.
• In some EU states, authorities issue standing exemptions for certain volunteer SAR organisations. In Romania, you should check whether a similar mechanism exists.
• Coordinating with the national emergency inspectorate and obtaining an operational authorisation tailored to those flights is the clearest path. Never assume that goodwill exempts you from aviation law.

A Closing Word on Keeping It Legal

The aviation rules for commercial drone work across the EU — and specifically in Romania — are built on a safety‑first philosophy. They reward operators who invest the time to build clear procedural documentation, keep hardware well‑maintained, and maintain open channels with their national authority. No checklist can capture every local nuance, so treat this guide as your operational compass, not a sealed instruction manual. Always verify with the relevant authority before submitting an application or launching a flight.
