Lock in subsidies without rework

Pronovo & one-time incentive Bern

Understand which documents and performance data need to align so your subsidy application goes through on the first try.

  • Align subsidy logic with quoting and commissioning
  • Keep technical data and evidence consistent
  • Think about economics and documentation together

Lock in subsidies without rework

Pronovo & one-time incentive Zurich

Find out what the Pronovo one-time payment means for a PV project in Canton Zurich: when to file, which documents need to be consistent, and how grid operator registration and commissioning fit together.

  • KLEIV programme: one-time payment for systems under 100 kW
  • Grid operator registration with EKZ or EWZ before commissioning
  • Prepare application deadlines and documents consistently

Lock in subsidies without rework

Pronovo & one-time incentive St. Gallen

Explains why Pronovo registration must happen before commissioning, how the grid operator process and EIV registration run in parallel in Canton St. Gallen — and which documents need to be ready in which order.

  • The sequence matters: why Pronovo registration must happen before commissioning — and what applies if registration was missed
  • Two separate registrations: Pronovo EIV and grid operator registration with SGSW as parallel processes in Canton St. Gallen
  • Installation notification and ESTI obligation: which documentation tasks fall to the licensed electrical installer

Lock in subsidies without rework

Pronovo & incentives PV Basel-Stadt

Explains how to prepare the Pronovo registration and the Basel-Stadt cantonal subsidy programme correctly for a PV installation — which sequence applies, which documents must be consistent, and what role IWB plays as the sole grid operator.

  • 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

Lock in subsidies without rework

PV incentives Canton Schaffhausen

Explains for Canton Schaffhausen how Pronovo, cantonal support, tax deductions and heritage-adjacent project cases should be considered together.

  • Separate Pronovo as the federal baseline from cantonal add-ons
  • Classify Schaffhausen projects correctly between standard roofs and sensitive townscapes
  • Connect economics, documentation and the next project step

Lock in subsidies without rework

Pronovo, AEW & tax rules Aargau

Explains how the Pronovo funding category, AEW feed-in model and the new Aargau tax rules from 2026 interact — and which project data needs to be consistently prepared.

  • KLEIV, GREIV or HEIV: which Pronovo funding category applies for a PV project in Canton Aargau — and why the classification must come first
  • AEW feed-in compensation 2026: fixed price with HKN or reference market price — what the difference is and when the model choice must be made
  • New AG tax rules from 2026: net principle for feed-in compensation and tax exemption for small producers up to 10,000 kWh per year

Lock in subsidies without rework

Pronovo one-time incentive PV Lucerne

Explains how to prepare the Pronovo one-time PV subsidy cleanly in Canton Lucerne — which funding category applies, the role of CKW or ewl as grid operators, and which project data must be consistent.

  • KLEIV, GREIV or HEIV: why the funding category comes first in planning — and what differs for installations without self-consumption in Canton Lucerne
  • Two grid operators in Canton Lucerne: how CKW outside and ewl within the city of Lucerne handle grid registration, metering concept and feed-in compensation
  • Pronovo registration before commissioning: which documents must be consistent — and how KEnG obligations and the subsidy logic relate

Settle permitting before the quote

PV permitting in Canton Bern

Find out whether your roof is a standard case or whether you should settle townscape, roof changes or special conditions before the quote.

  • Townscape, roof changes and local pre-checks
  • Prepare municipal documents and follow-up questions cleanly
  • When approval matters instead of a simple filing path

Settle permitting before the quote

PV permitting Canton Zurich

Find out why most PV projects in Canton Zurich no longer require a formal permit procedure since 2023 — and which exceptions should be clarified early.

  • Notification procedure instead of building permit since January 2023
  • Exceptions for listed buildings, protected zones and facade installations
  • When a local pre-check saves time and effort

Settle permitting before the quote

PV permitting Canton Aargau

Find out why most PV projects in Canton Aargau are handled with a notification requirement rather than a building permit — and which design requirements, protected zones or special cases should be clarified early.

  • Design requirements under §49a BauV and Art. 32a RPV
  • Exceptions for listed buildings, ISOS townscapes and protected zones
  • EVEN notification form, documentation and 30-day deadline

Settle permitting before the quote

PV permitting Canton Lucerne

In Canton Lucerne, system size determines the procedure: small installations up to 20 m² are exempt from notification under certain conditions, larger systems require notification — a building permit is only needed for monument protection, townscape protection or systems not sufficiently adapted.

  • The 20 m² threshold: when is a system notification-free, subject to notification, or requiring a building permit?
  • Townscape protection, ISOS inventory and monument protection in Canton Lucerne: when does notification become a full permit requirement?
  • Cantonal Energy Act (KEnG) since March 2025: new self-generation obligations for new buildings and major renovations

Settle permitting before the quote

PV permitting St. Gallen

Explains when PV systems in Canton St. Gallen only require notification, which design requirements apply under Art. 32a RPV — and how the new cantonal permit practice with colour-coded map works for listed buildings and townscape protection zones.

  • Design requirements under Art. 32a RPV: what applies to pitched and flat roofs in Canton St. Gallen
  • New 2024 permit practice: the colour-coded online map for monument and townscape protection zones in Canton St. Gallen
  • Notification, dialogue obligation or formal building permit: which procedure applies when in Canton St. Gallen

Settle permitting before the quote

PV permitting Basel-Stadt

In Basel-Stadt, the zoning category and heritage protection status determine whether a PV installation requires notification or a full building permit. The revised Solar Offensive 2025 has lifted the ban on historic town centres — but in sensitive areas a building permit remains required.

  • Notification in practice: which zones and technical conditions determine notification or permit in Basel-Stadt
  • Historic town centres and heritage protection: what the 2025 Solar Offensive specifically changes for PV projects in sensitive areas
  • Solar obligation and transition period: which buildings with more than 100 m² of roof area are affected and which exceptions apply

Plan storage at the right moment

Battery storage PV Canton Bern

Identify which factors determine the value of battery storage — before quoting, sizing and system integration are locked in.

  • Review consumption profile and evening load before sizing
  • System integration with heat pump, wallbox and grid registration
  • Assess economics as a scenario instead of a blanket recommendation

Project workflow without friction

Grid-operator registration PV Bern

See how registration, metering and commissioning fit into one smooth workflow — so nothing falls through the cracks.

  • Define registration and metering concept before execution
  • Align electrical planning and documents with the site work
  • Document commissioning without loose ends

Test economics realistically

PV economics Canton Zug

Assess which factors genuinely drive PV system economics in Canton Zug — from self-consumption and current WWZ tariffs to ZEV models, LEG and Pronovo one-time payment.

  • Self-consumption vs. feed-in: why the market-price shift from 2026 changes the economics
  • ZEV, vZEV and LEG in Canton Zug: which model makes sense when?
  • Tax deduction and Pronovo: how upfront contributions materially change the net investment
