PV Installation Aargau – Roof & Electrical

People looking for PV installation in Canton Aargau compare more than modules. They compare execution quality, roof protection and coordination. That is why this page focuses on the points that matter before quoting and installation.

Local system fit

Aargau is known as the "energy canton" – with PSI (Paul Scherrer Institute) in Villigen researching solar technologies and PARK INNOVAARE as an innovation cluster. AEW Energie AG compensates feed-in at 11.15 Rp./kWh (2025, including HKN). The high density of industrial and commercial buildings offers enormous potential for large rooftop systems. Additionally, the canton supports battery storage with dedicated contributions.

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.

What really matters for installation on site

People looking for PV installation in Canton Aargau compare more than modules. They compare execution quality, roof protection and coordination. That is why this page focuses on the points that matter before quoting and installation. Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.

Service focus

  • 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, measurement protocol, photos – everything needed for acceptance, grid operator and future service.

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.
