Short answer
What you need to know first.
Helps owners in Basel-Stadt connect the current Pronovo framework for PV with local grid and funding questions, from the funding category and IWB to the distinction from cantonal add-on offers.
Important
Pronovo is the primary source for funding categories, the application route, the guideline and current detailed questions on the one-time payment. If cantonal or local add-on offers are relevant in Basel-Stadt, they should be treated as separate programmes and checked directly with the responsible authority. For concrete projects, current steps and special cases should therefore always be verified directly with Pronovo and the relevant local bodies.
Decision points
What determines the right path.
The Pronovo page clearly distinguishes between KLEIV, GREIV and HEIV. For owners in Basel-Stadt, the first crucial step is therefore the correct funding category and not the blanket assumption that all PV projects follow the same funding path.
For many residential buildings in Basel-Stadt, KLEIV is the likely category because it applies to systems below 100 kW. For larger multi-family or commercial projects, it should be checked early whether GREIV becomes relevant instead.
According to Pronovo, HEIV is intended for systems without self-consumption in the range from 2 kW to 149.99 kW. This setup should not be confused with typical self-consumption projects because it changes the funding and project logic.
Federal funding and cantonal add-on offers should be kept separate. In Basel-Stadt, a separate cantonal funding environment may be relevant alongside Pronovo. These programmes should not automatically be understood as part of the EIV but should be reviewed separately.
IWB is a central point of reference in Basel-Stadt for the technical integration of the installation. Grid-related topics such as registration, metering concept and technical approvals should therefore be considered early, even though the funding logic runs through Pronovo.
Consistent project data also remain the most important lever against follow-up questions here. Funding category, capacity, system type and location details should remain consistent across the quote, Pronovo documentation and local process steps.
Sequence
How the project stays cleanly managed.
- 1
Start by determining the funding categoryaccording to Pronovo, KLEIV applies to systems below 100 kW, GREIV to systems from 100 kW, and HEIV to installations without self-consumption in the range from 2 kW to 149.99 kW. This classification belongs at the beginning of planning.
- 2
In parallel, clarify local grid topicsin Basel-Stadt, IWB is the relevant point of reference for grid connection, metering concept and technical integration. These points should be clarified early so that funding and execution logic fit together.
- 3
Capture the technical project data consistentlycapacity, system type, self-consumption logic and location details should be documented so that they align across the quote, Pronovo documentation and local process steps.
- 4
Check the current Pronovo materials before filingthe current EIV page, the FAQ, the application route and the guideline define the authoritative current status. These current materials should always be used, especially for funding categories and special cases.
- 5
Review cantonal add-on offers separatelyif additional funding offers are relevant in Basel-Stadt alongside Pronovo, they should be examined separately from the federal support and only then integrated into the project’s overall logic.
Checklist
Questions to settle before the quote.
- Two subsidy sources, two application processes: prepare Pronovo EIV and Basel-Stadt cantonal subsidy programme separately and on time
- IWB as the sole grid operator in Basel-Stadt: clarify grid registration, metering concept and feed-in measurement early
- Old town protection and condominium ownership: when building permits or community consent affect the subsidy process
