Substance
The roof leads, not the sales graphic.
Mounting, waterproofing, shading and the electrical setup are clarified before anything is promised. No quote without understanding the building.

Solar systems in Sins – Your regional partner
Whether single-family home or commercial roof in Sins: We clarify roof type, statics and cable routing before the first rail is installed.
Region: Sins, Aargau
Swiss project delivery
Initial estimate in a few minutes
Everything from one team — through to handover
Building in focus
From roof surface to energy surface.
Full-black, in-roof or flat-roof: in Sins we plan not for a datasheet, but for a building that has to stand up architecturally and within its local context.
Transformation
Architecture first
Architecture, use and yield planned together.
In Sins, materiality, visual lines and technical details are aligned so the system fits the design language and performs cleanly over time.

Precision
Installation becomes visible before it has to be explained.
The system grows precisely into the building: tight penetrations, protected facade, modules sliding into the rails, and an aesthetic that fits the architecture instead of disturbing it.
Calm
Technology that stays calm after handover.
The inverter, registration and documentation are done, cable routes and labels stay traceable, and the roof becomes a calm, reliable energy source for everyday use.

Process
Understand first, then promise.
From first contact to commissioning, every system follows a clear process. We clarify roof, electrical work, incentives and expansion path completely — only then you receive a reliable quote. No site chaos, no wishful math.
01
System step
Initial assessment
Your key details are enough: in a few minutes you receive a first orientation.
02
System step
3D survey & technical review
We measure the roof by drone and clarify electrical work, regulations and the grid operator.
03
System step
Transparent quote
You see clear line items, realistic ranges and sensible options such as storage or a wallbox.
04
System step
Planning, installation & commissioning
We coordinate execution, registration, acceptance and documentation until your system is reliably connected to the grid.
Swiss facts
Residential·Commercial
One-time remuneration
Federal support depends on system type and size band. For many residential projects it is now a per-kW rate without a separate base amount; Vigorek clarifies which logic fits the property, canton and grid operator.
Storage as a system decision
A battery only makes sense when it fits the usage profile, the tariffs and the home technology. We assess this as part of the overall planning — not as a late upsell.
Realistic payback
We calculate with ranges instead of wishful numbers: self-consumption, remuneration and tariff logic together give a realistic picture of your economic return.
Next step
What does your solar system save?
As a next step, we map self-consumption, feed-in tariff, and payback for your property. That creates the first reliable estimate of its economic performance.
The focus stays on self-consumption, feed-in tariff, and an expansion path that works both technically and economically.

Pre-check
3D survey before a binding quote
Ranges stay ranges at first. A project only becomes binding after the drone survey, technical review and a complete property assessment.
Electrical
Coordination by licensed professionals
From electrical planning through protection equipment to grid registration: all safety-critical steps are carried out by licensed electrical professionals — in-house or through vetted partners.
Quote
Transparent line items instead of package promises
Materials, installation, scaffolding, electrical work, registration and commissioning are listed individually so variants and ranges remain traceable.
Execution standard
Our most important execution principles at a glance.
Safety
Fall protection
Scaffolding/PPE as required — safety before speed.
Roof
Waterproofing
Clean penetrations and appropriate mounting so the roof stays watertight long-term.
Electrical
Electrical installation to standard
Neat cable routing, a protection concept tailored to the property, and clear labelling.
Acceptance
Documentation
Wiring diagram, string plan, datasheets and photo documentation — for smooth acceptance and service.
Regional clarification
Not every system follows the same logic in Sins.
In Switzerland, permits, grid operator, metering concept and incentive path always depend on the property, municipality and canton. These are exactly the points clarified early before a quote becomes binding.
That avoids a generic promise and creates a well-founded assessment that fits the region and the building.

Fast entry
Plan your solar system — without missing a single question
Find the answers that separate a smooth project from costly detours. Pick your topic, read the guide, see your next step.
Settle permitting before the quote
I want to clarify permitting first
Afterwards you'll know whether your roof is a standard case — or exactly where to look before requesting a quote.
Lock in subsidies without rework
I want to sort incentives and documentation
Afterwards you'll have clarity on which documents need to align so subsidies and project flow don't drift apart.
FAQ
The questions before the decision.
Not every uncertainty needs a sales call. The most important points are explained here deliberately, factually and without artificial urgency.
It depends on canton/municipality, property and protection regulations. In many cases, a notification procedure is sufficient; in core zones, for heritage protection, or for structural changes, further clarifications are needed. We clarify this early and provide the required documents.
The Founders
Engineering depth. Financial structure.
Two founders, two domains of expertise – one shared conviction: solar installations work long-term only when engineering and business case fit together from the start.

If it fits, the next step gets a clear shape.
Before a project begins, you need clarity on roof, consumption and technical setup. The following steps are arranged so you move from a first overview to a reliable foundation, without any pressure.
01
Align the baseline first
Roof, usage profile and target setup are aligned before a polished but vague number enters the room.
02
Check the technical reality
Electrical scope, metering, grid-operator constraints and expansion path are read as one connected system.
03
Move forward with clarity
If the project fits, the next step is a traceable quote instead of pressure or sales haze.
Next step
The initial assessment remains the cleanest entry point: fast enough for momentum, concrete enough for a real conversation based on your building.
