COMPLETE PV SYSTEMS · OPTIONAL STORAGE
With around 1,830 hours of sunshine (Payerne station, 1991 to 2020 average) and an active climate programme, the Canton of Vaud is one of the most attractive PV markets in Romandie. The «100 millions pour le climat» programme (2023–2027) complements Pronovo and the tax deduction with storage subsidies and contributions for comprehensive renovations. Romande Energie, SIL Lausanne, and Sinergy Vevey offer reliable feed-in tariffs and ZEV models.
With Romande Energie, Vaud is one of the few Swiss regions with a listed energy utility and has set ambitious climate targets. Lausanne and the Riviera benefit additionally from lake reflection and many unshaded rooftops on viticultural and commercial buildings.

Costs
Example: 5–10 kWp rooftop PV: CHF 14,500–23,300. Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated with the reference curve of the SFOE price survey (CHF 1,628 per kW plus CHF 5,278): the range reflects different system sizes. A market comparison, not a quote.
Roof renovation, structural reinforcement and replacement of the meter cabinet are not included. Roof access, electrical work and planning can change the price. Your specific quote follows the property assessment.
Costs with calculation and sourcesSizing
A typical household using around 4,000 kWh per year needs roughly 25 m² of module area (Swissolar, February 2024). As a starting figure, global irradiation in Canton Waadt is 1,284 kWh/m² per year (MeteoSwiss, Payerne station, 1991 to 2020 average). Whether that works on your roof in Waadt depends on orientation, pitch and shading, not on the floor plan.
Two federal bonuses explicitly do not apply to a single-family home: the winter electricity bonus requires at least 100 kW, and the tilt bonus at least 75 degrees of pitch. Neither applies to an ordinary pitched roof. Counting on them makes the business case look better than it is.
Clarify notification and permission before installationStorage
Battery storage earns its money through self-consumption. Electricity you use yourself saves not only the energy price but also grid fees and levies, which is why it is worth more than exported electricity. That is what decides whether a battery pays off.
Since 1 January 2025, an association for self-consumption (ZEV) may also use the existing connection lines. This makes apartment buildings and neighbourhood setups considerably cheaper, as no dedicated line is required. The grid operator depends on the municipality; in the Canton of Waadt they include Romande Energie, SIL Lausanne, Sinergy Vevey.
When battery storage makes senseServices
PV system, heat pump, storage, wallbox and monitoring from one team. Every service is planned as part of a working energy system.

Components by
Process
We clarify roof, electrical work, incentives and expansion path before you receive a quote. No site chaos, no wishful math.
Your key details are enough for a first, honest orientation. No appointment, no obligation.
We measure the roof by drone and clarify electrical work, regulations and the grid operator.
You see every line item individually, realistic ranges and sensible options such as storage or a wallbox.
Planning and installation by Vigorek. Electrical connection, grid registration and commissioning are handled by an electrical contractor licensed under the NIV. We coordinate schedules and documents.
From installation practice
Hooks and rails disappear under the modules. That is exactly where it is decided whether a system holds and the roof stays watertight. Marc Hammerschmidt has installed roofs like these himself and recorded the work on his phone.
Site diary · one tiled roof
Hooks come first. They sit under the tiles and later carry rails, modules, wind and snow.
Aluminium rails go onto the hooks. Where they end is decided in the plan, not on the roof.
By day four, the field is in place. When hooks and rails are right, the joints run straight by themselves.

The Founders
You know before signing who calculates your project and who builds it: two founders, one for engineering, one for finance. A solar system only works long-term when both fit together from the start.

Co-Founder · Strategy & Finance
Christian has been an independent management consultant and interim manager since 2015, most recently as Interim Treasury Manager at an energy storage manufacturer. Before that he was a Senior Manager at KPMG. He brings the financial structure: liquidity planning, transparent calculations and no project whose numbers don’t add up.

Co-Founder · Engineering & Planning
Marc handles the technical side: planning, structural analysis and system integration. He has helped install systems on roofs himself and plans so that nothing has to be improvised on the roof.
Clarity before commitment
Canton check
For local PV projects, the municipal boundary is not the only factor: roof access, snow load, shading, meter cabinet and grid connection determine the project flow.
Canton Waadt has its own rules for subsidies, permits and grid connection. We check them before quoting and record them in the project documentation.
Global irradiation in Canton Waadt: 1,284 kWh/m² per year (MeteoSwiss, Payerne station, 1991 to 2020 average).
Relevant grid operators in the canton: Romande Energie, SIL Lausanne, Sinergy Vevey. Metering concept and registration are clarified before execution.
Roof-mounted systems on standard buildings in Vaud only require notification (Annonce de travaux). A regular building permit is needed for listed buildings, systems in heritage protection zones, and facade PV on protected objects. The Commune is the first point of contact.
The Canton of Vaud launched the «100 millions pour le climat» programme for 2023–2027. For private households, storage subsidies and contributions for comprehensive renovations are particularly relevant, complemented by the national Pronovo one-time payment and full tax deductibility as property maintenance. Exact rates are adjusted annually and available from the canton or Romande Energie.
Your key details produce a first orientation on price range, incentives and payback. That is the basis on which we talk about your project.

Core services
The key services, tailored directly to Waadt and the local requirements in your region.
Regional service
Cantonal documents are available in French. Have the municipality, plot and system type ready to establish the appropriate notification or permit. A canton-wide statement cannot replace this property-specific assessment.
Regional service
In Canton Waadt, flat roofs on commercial buildings and multi-family homes represent the largest untapped solar area. Vaud has adopted MuKEn principles into its cantonal Energy Law (LVLEne). New buildings must meet self-generation requirements, and heating replacements favour renewable systems. PV combined with heat pumps is considered best-practice.
