Background
#PV incentives in Appenzell Ausserrhoden in 2026 consist of the Pronovo one-time remuneration and a cantonal top-up of up to 50% of that EIV.
In the standard case, this concerns a grid-connected new system or extension from 2 kWp, with the application submitted only after commissioning and after Pronovo's decision has become legally effective. Systems receiving the high one-time remuneration without self-consumption, and the part required by law under Art. 10a kEnG, do not receive an additional cantonal contribution.
Under the current programme, the canton states a maximum of CHF 100,000 per project; a change from 1 January 2027 has been announced but still depends on approval by the cantonal parliament.
What counts for funding
#The support amount follows the Pronovo basis: for systems commissioned from 1 September 2025, the cantonal contribution is capped at 50% of the federal EIV. Commissioning date, capacity, system type and tilt angle therefore matter, not a freely chosen flat amount.
The minimum size is binding: the canton supports grid-connected solar systems from 2 kWp. Replacement, maintenance and repairs do not qualify as a supported new system or extension.
Timing is a hard eligibility condition: the application goes to the Office for the Environment only after commissioning and after the final Pronovo decision is legally effective. Under the cantonal rule, an earlier application is not processed.
Self-consumption changes the support route: systems receiving HEIV under Art. 25 para. 3 EnG are excluded from cantonal support. Before design, it must therefore be clear whether self-consumption is planned or HEIV is chosen.
The legally required minimum system must be separated: where Art. 10a kEnG and Art. 19abis para. 1 kEnV require a minimum size, the canton does not add support to that required part. Only the eligible part under the applicable rules remains supported.
The cap limits larger projects: the cantonal contribution is limited to CHF 100,000 per project. For larger systems, the project calculation must therefore separate Pronovo, cantonal top-up, self-consumption and non-supported components.
The process in seven steps
#Tick off for your project
Classify the support case
record the Appenzell Ausserrhoden location, new system or extension, capacity from 2 kWp, self-consumption, system type and planned commissioning date. At the same time, check whether Art. 10a kEnG requires a minimum system.
Determine the Pronovo EIV
have the federal contribution assessed using commissioning date, capacity, attached or integrated design and tilt angle. Pronovo's final decision is the basis for the later cantonal application.
Check exclusions before ordering
clarify whether HEIV without self-consumption, a federal auction, a mere replacement or maintenance is involved. These cases are excluded from or not eligible for the cantonal top-up.
Build and commission the system
coordinate installation, grid connection, safety certificate and Pronovo registration so that the actual commissioning date and system data are documented.
Wait for the Pronovo decision
do not submit the cantonal application with a provisional EIV calculation. Wait for the final assessment until the decision is legally effective.
Submit the cantonal application
enter it in the funding portal, print and sign the form, and send it with the legally effective Pronovo decision and required documents to the Office for the Environment.
Check the payment
keep the contribution and payment decisions, EIV documents, invoices and system records. If the project differs from the application or eligibility later lapses, the contribution may be adjusted or reclaimed.
Checked for your roof, not just read up on
Once the framing is clear, a property-specific check with roof, grid and documentation is worthwhile.
