PV installation Aargau: solar mounting company
People looking for PV installation in Canton Aargau compare more than modules. They compare execution quality, roof protection and coordination. Exactly these points decide on a clean result before quoting and installation.
Clarify before quoting
Aargau is known as the "energy canton" – with PSI (Paul Scherrer Institute) in Villigen researching solar technologies and PARK INNOVAARE as an innovation cluster. From 2026 AEW Energie AG pays a fixed tariff of around 8.2 Rp./kWh including HKN or the BFE reference market price without HKN (statutory minimum 6 Rp./kWh up to 30 kW). The high density of industrial and commercial buildings offers enormous potential for large rooftop systems. At cantonal level, Aargau funds facade PV (integrated facade CHF 400/kWp, mounted facade CHF 200/kWp, from 75 degrees tilt); there is no cantonal battery storage subsidy.
For Aargau we plan PV installations object-specifically: mounting structures per SIA 261, SUVA-compliant fall protection and complete handover documentation before the system goes live.

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.
Service focus
What really matters for installation on site
Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.
- Mounting structure matched to tile, sheet metal, facade or flat-roof systems – not generic, but dimensioned object-specifically to wind zone (SIA 261), snow loads and building height.
- Clean cable routing with documented penetrations and roof membrane protection. Every transition between roof and electrical installation is photographed and recorded.
- Coordination of scaffolding, fall protection (SUVA-compliant), installation logistics and object-specific safety requirements – including a mounting concept prior to material ordering.
- Photo documentation and traceable handover: single-line diagram, string plan, data sheets and photos. The electrical contractor issues the test report and the safety certificate, so acceptance, grid operator and future service have everything in one place.
Regional framework
Why this canton shifts the priorities
The federal register lists 26,308 photovoltaic systems with 762 MW in Aargau, 4,333 of them added since January 2025 (as of 14 Sep 2026). More than 90 grid operators serve the canton; AEW is responsible in 74 of the 196 municipalities. New buildings over 300 m² need a solar system covering at least 20% of the building area; single-family homes are exempt.
- In Canton Aargau, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.
- Owners compare execution quality, roof protection and clear ownership more than simple price promises.
- Site logic directly affects timing, appearance and future maintenance.
Project logic
How roof, installation and electrical work fit together
The order records these steps, responsibilities and required documents. Outstanding assessments belong in the schedule before work begins.
- Mounting structure and scaffolding planned around roof type and access.
- Clean penetrations, orderly cable routing and documented handover.
- Aligned workflow between installation, electrical work and commissioning.
Regional context
PV 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
- Installation quality is decided before site work starts: roof access, mounting structure, cable routing and fall protection need to be planned together.
- Grid & registration
- For Canton Aargau, grid operators such as AEW Energie AG, metering concept and commissioning are aligned early.
- Decision reason
- In Canton Aargau, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.
- Execution
- Mounting structure and scaffolding planned around roof type and access.
- 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.
AEW is the grid operator in 74 of the 196 municipalities in Aargau; a self-consumed kWh is worth 16.9 to 33.3 ct in 2027 depending on the utility (ElCom).
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. No separate cantonal PV grant. Investment funding comes from Pronovo (mounted under 30 kW CHF 360/kW, integrated CHF 400/kW). The 2026 energy programme only grants a bonus on subsidised roof or facade insulation (buildings permitted before 2000): plus CHF 30/m² for a pitched-roof rooftop system, plus CHF 100/m² for in-roof or facade systems, plus CHF 20/m² on a green flat roof; PV coverage at least 70% or 50%, application before construction.
Permits and energy law
Notification procedure for sufficiently adapted systems on roofs and facades: solar form to the municipal council, start of work if no objection is raised within 30 days. A building permit is required in old town, core, village and hamlet zones, for cantonal heritage properties and their surroundings and in protected townscapes. 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
The federal register lists 26,308 photovoltaic systems with 762 MW in Aargau, 4,333 of them added since January 2025 (as of 14 Sep 2026). More than 90 grid operators serve the canton; AEW is responsible in 74 of the 196 municipalities. New buildings over 300 m² need a solar system covering at least 20% of the building area; single-family homes are exempt. There is no separate cantonal PV grant, only the bonus on subsidised roof or facade insulation (CHF 20–100/m² with a PV system installed at the same time). The system itself is funded by the federal Pronovo one-time payment.
