Solar system Aarau – Planning to commissioning

In Aarau, owners usually want more than mounting. They want a project flow without loose ends. This page brings together the topics that matter before execution and commissioning.

Local system fit

In Aarau, defensible quotes, realistic sequencing and clean coordination between roof work, electrical work and registration matter most.

For a solar installation in Aarau, success depends not only on module area but on the process: 3D survey, transparent quote, grid-operator coordination and commissioning with full documentation. Vigorek handles the full coordination — from initial assessment to handover.

Service focus

What the full installation secures on site

In Aarau, owners usually want more than mounting. They want a project flow without loose ends. This page brings together the topics that matter before execution and commissioning. From initial assessment and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Service focus

  • Initial assessment and 3D drone survey: roof, orientation, shading, electrical setup and possible constraints — before any quote is prepared.
  • Transparent quote with clearly separated line items: material, installation, scaffolding, electrical, registration, commissioning — each one individually listed.
  • Coordination of Pronovo registration, metering concept, grid-operator queries and meter replacement through to full commissioning.
  • Optional integration of battery storage, wallbox and energy management — only where the usage profile and expansion goals support it.

Why this canton shifts the priorities

In Aarau, defensible quotes, realistic sequencing and clean coordination between roof work, electrical work and registration matter most. Aargau: highest cantonal subsidy in Switzerland with CHF 380/kWp. Despite best subsidies only 7.6% potential utilized — huge growth opportunities! Parking lot solar niche subsidy unique in Switzerland. Aargau solar offensive active.

Regional framework

  • A technical pre-check saves time when permits, metering or electrical setup are not standard.
  • Owners in Aarau usually prefer one coordinated flow instead of multiple subcontractors.
  • A documented commissioning reduces future questions and service effort.

Project logic

How coordination makes the difference

In Aargau, PV systems can be fully deducted from taxes as value-maintaining and energy-saving investments. The canton allows distribution over several tax periods when taxable income is exceeded. Pre-check for roof, shading, electrical setup and potential constraints.

Project logic

  • Pre-check for roof, shading, electrical setup and potential constraints.
  • Coordination of the grid operator, metering concept and commissioning.
  • Clear handover instead of an incomplete site close-out.

Cantonal framework

Which cantonal framework really shapes Aarau.

Aarau operates inside the same cantonal system as other projects in Aargau: taxes, incentives and energy law shape both speed and economics.

Local context

Aarau decides locally, but is shaped canton-wide.

Aargau is known as the "energy canton" – with PSI (Paul Scherrer Institute) in Villigen, which also researches solar technologies. The high density of industrial and commercial buildings offers enormous potential for large rooftop systems.

In Aarau, defensible quotes, realistic sequencing and clean coordination between roof work, electrical work and registration matter most.

Tax and subsidy logic

In Aargau, PV systems can be fully deducted from taxes as value-maintaining and energy-saving investments. The canton allows distribution over several tax periods when taxable income is exceeded. CHF 380/kWp cantonal subsidy for roof-integrated systems — HIGHEST in Switzerland! Calculation example 10 kWp: Federal CHF 3,550 + Canton CHF 3,800 = Total CHF 7,350 (41% subsidized!). Parking lot solar bonus: unique offering for commercial/industrial.

Permits and energy law

Notification via EVEN portal. Standard roof systems require no building permit. Parking lot solar: simplified approval. Aargau solar offensive supports quick action. Aargau relies on individual responsibility, flanked by MuKEn 2014 requirements for new buildings. The revised Energy Act (EnergieG AG) requires self-generation for new buildings and restricts fossil heating upon replacement.

Market signal and location

Aargau: highest cantonal subsidy in Switzerland with CHF 380/kWp. Despite best subsidies only 7.6% potential utilized — huge growth opportunities! Parking lot solar niche subsidy unique in Switzerland. Aargau solar offensive active. Cantonal subsidy programmes complement Pronovo partly for specific storage solutions. AEW Energie AG offers attractive feed-in tariffs as regional provider. Additionally, Aargau subsidizes consulting through the cantonal energy advisory service.
