Context

How this service works in Aargau in practice.

Aargau comes with its own framework conditions – from incentives and tax treatment to technical requirements. From those, a cleanly managed project flow for your property takes shape.

01Service focus

What the full installation secures on site

In Canton Aargau, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. That is exactly how we run solar projects – from the pre-check to documented commissioning. From the initial estimate and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Initial estimate and 3D survey (drone): 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.

02Regional framework

Why this canton shifts the priorities

Aargau is among the few cantons that did not proactively implement MuKEn 2014 – but since 2025, the federal solar obligation applies for new buildings over 300 m². AEW Energie AG compensates at 11.15 Rp./kWh (including HKN). The canton pioneers agri-PV: four pilot projects generate up to 2.2 GWh/year. Spatial planning adjustments (July 2022) enable agri-PV on agricultural land – a regulatory framework unique in Switzerland. 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.

In Canton Aargau, a pre-check saves time when permits, metering or electrical setup are not standard.
Owners want traceable quotes instead of aggressive package promises.
A documented commissioning reduces later questions and service overhead.

03Project logic

How coordination makes the difference

Pre-check for roof, shading, electrical setup and potential constraints.
Coordination of registration, metering concept and commissioning.
Clean handover with traceable documentation for operations and service.

Regional context

Solar system installation in Aargau: what matters here

In Canton Aargau, cantonal rules, the responsible grid operator and local permit procedures shape how a project is planned and delivered. The points below show what really matters before quoting, installation and handover.

Regional starting point

In Canton Aargau, incentives, grid operators and permit procedures change the priorities for this service.

Service core

A complete solar installation depends on sequencing, grid-operator coordination, electrical planning and clean commissioning.

Grid & registration

For Canton Aargau, grid operators such as AEW Energie AG, metering concept and commissioning are aligned early.

Decision reason

In Canton Aargau, a pre-check saves time when permits, metering or electrical setup are not standard.

Execution

Pre-check for roof, shading, electrical setup and potential constraints.

Economic frame

Feed-in tariff and self-consumption are matched to the property; in the canton, 8.2 Rp./kWh (AEW) is one relevant reference point.

Cantonal framework

Which cantonal framework shapes the project in Aargau.

The technical service stays the same, but the project frame changes with the canton. That is exactly where incentives, tax treatment and MuKEn requirements become strategically relevant.

Local context

Aargau sets the economic pace for this service.

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.

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.
