Short answer
What you need to know first.
For a PV system in Basel-Landschaft, building procedure and grid process need to run in parallel. The standard case is: check location and notification or permit route, identify the responsible grid operator, submit connection request and technical data, define metering and self-consumption concept, install the system, test it, issue the safety certificate and commission it properly only after grid-operator acceptance or release. Whether Primeo, EBL or another distribution grid operator is responsible depends on the specific location.
Important
This overview is general information for PV projects in Basel-Landschaft and not individual legal, tax, subsidy or grid-connection advice. The current requirements of the responsible municipality, building inspectorate, specific distribution grid operator, ESTI/NIV rules, funding body and appointed inspection body are binding. Battery storage, ZEV/vZEV, commercial properties, protected status or grid reinforcement in particular require property-specific review.
Decision points
What determines the right path.
The responsible grid operator is not a formality. Depending on the municipality, different distribution grid operators may be relevant in Basel-Landschaft. EBL describes technical assessment of connection requests for energy generation systems and points out that high demand and complex grid upgrades can lead to longer processing times. Grid clarification therefore belongs before the installation date.
The regional technical rules are binding technical connection conditions for consumer, generation and storage systems on the low-voltage grid. For PV projects, this means inverter, protection concept, metering, equipment order, battery operation and documents must fit the grid-operator logic, not only the roof layout.
Primeo describes on-site acceptance for photovoltaic systems and names meter replacement, release of feed-in metering and the safety certificate with AC/DC relevance as part of the route to commissioning. This makes clear that completed installation and economic operation are not the same thing.
ESTI states that a safety certificate must be issued for new installations, conversions, extensions and modifications. For PV systems, electrical testing is therefore not an add-on at the end, but a central handover document for owners, grid operators and later inspection.
The metering concept determines self-consumption and feed-in. A detached house with simple feed-in, a multi-family building with ZEV/vZEV, a commercial roof with high daytime load or a system with battery storage need different meter and billing logic. This decision affects quote, electrical work and commissioning.
Sequence
How the project stays cleanly managed.
- 1
Clarify location and procedurecheck municipality, grid area, building zone, protection status and existing notification or permit questions. The Basel-Landschaft notification route is important, but it does not replace technical grid approval by the responsible distribution grid operator.
- 2
Define the technical base datadocument module area, inverter output, battery, grid-parallel operation, cable routes, protection concept, building connection and expected feed-in. These data must remain consistent across quote, connection request, metering concept and Pronovo documents.
- 3
Submit connection request and metering concept before installation release: align grid-operator details, equipment order, meter question, self-consumption, feed-in and, if needed, ZEV/vZEV with the regional technical rules. If grid capacity or the system is complex, schedule reserve time.
- 4
Carry out installation and electrical work traceablydocument mounting system, roof membrane protection, DC and AC cables, inverter location, labelling, disconnection options and test access so grid operator, inspection body and owner can assess the same system.
- 5
Complete commissioning with a full handoverhand over measurement and test protocol, safety certificate, grid-operator release or acceptance, meter replacement, monitoring access, photos, warranties and Pronovo-relevant data in an orderly way. Only then is the system not just built, but documented for operation.
Checklist
Questions to settle before the quote.
- Clarify the responsible grid operator and connection request before installation
- Plan metering concept, self-consumption, feed-in and meter replacement together
- Secure safety certificate, measurement and test protocol and handover dossier
- Do not manage building procedure, grid approval and Pronovo data separately
