Service focus

What really matters for installation on site

People searching for PV installation in Winterthur usually compare execution quality, timing and roof protection. This page prioritises those factors. 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.

Regional framework

Why this canton shifts the priorities

Winterthur is especially relevant for projects where clear execution, documented installation and a clean handover matter. Zurich is Switzerland's largest cantonal market. With over 12,600 existing installations and only 4% of potential used, this represents the greatest growth potential. The combination of high incomes (maximum tax deduction) and high roof availability (70%+ suitable) makes Zurich the most attractive PV market in Switzerland.

Regional framework

  • Clean execution reduces later service and warranty issues.
  • On residential and commercial roofs, site logistics often decide timing and quality.
  • Owners expect defensible execution rather than simple panel placement.

Project logic

How roof, installation and electrical work fit together

In the Canton of Zurich, investments in PV systems are 100% deductible as property maintenance – for both new installations and replacements. Costs can be spread over up to three tax periods. Mounting structure matched to roof type and site access.

Project logic

  • Mounting structure matched to roof type and site access.
  • Documented penetrations and orderly cable routing.
  • Clean handover aligned with electrical work and commissioning.

Cantonal framework

Which cantonal framework really shapes Winterthur.

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

Local context

Winterthur decides locally, but is shaped canton-wide.

Zurich is a pioneer in ZEV projects (self-consumption associations) in multi-family houses and has the most registered ZEV communities nationwide. ETH Zurich actively researches building-integrated solar technology.

Tax and subsidy logic

In the Canton of Zurich, investments in PV systems are 100% deductible as property maintenance – for both new installations and replacements. Costs can be spread over up to three tax periods. Zurich has no general cantonal PV top-up. The relevant elements are the Pronovo one-time payment, the cantonal battery storage subsidy of CHF 500/kWh (max. CHF 15,000, limited until the end of 2026), and municipal programs depending on the municipality. In the City of Zurich, EWZ is relevant with an average standard tariff of 12.91 Rp./kWh and 14 Rp./kWh in the LEG model.

Permits and energy law

Since January 1, 2023, most solar systems in Canton Zurich only require notification (30 days before construction) — no building permit. Exceptions: listed buildings, protected zones, facade systems on protected objects. Zurich implemented MuKEn 2014 as of 2022. New buildings must install at least 10 watts of solar capacity per square meter of energy reference area. The revised Energy Act (EnG ZH) also requires switching to renewable systems when replacing heating.
