Engineering built to last, design built to blend in.
Our approach goes far beyond installing components. We design a coherent and resilient energy ecosystem in which technology serves overall performance and the harmony of your home.
The three pillars of excellence.
Millimetre-precise analysis
We use 3D scanning tools to model your roof. This precision lets us anticipate every constraint and optimise panel placement for maximum output.
Bauhaus aesthetics
Form follows function. We select Full Black technologies and mounting systems so your solar installation enhances your home's architecture rather than disrupting it.
Energy sovereignty
We connect your photovoltaic output to your heating and electric mobility to intelligently and automatically reduce your dependence on the grid.
From audit to autonomy.
The impartial audit
An expert visits you to assess your real needs — no unnecessary oversizing.
Custom-tailored design
Our engineers design your installation taking into account the aesthetic and technical specifics of your roof.
Operational excellence
No subcontracting. Our own installation and electrical teams ensure a safe and meticulous fit.
Digital serenity
We configure your monitoring app so you can track production and savings in real time, wherever you are.
Why our approach makes the difference?
Unlike standard models, Opus Solar manages the entire value chain — from feasibility study to final commissioning. This control allows us to guarantee short timelines, impeccable finish quality and a genuinely effective after-sales service.
“A good approach means above all an installation that goes unnoticed. If you no longer see your panels but you see the difference on your bill, then we've accomplished our mission!”Let's talk
Does Opus Solar handle the subsidy applications?
Absolutely. Our teams handle the entire administrative process for both federal (Pronovo) and cantonal incentives for photovoltaic installations.
How long does the installation take?
Plan for 2 to 5 days on-site for a standard residential installation, once the administrative file is validated.
Do I need to redo my roof before installing panels?
Not necessarily. Our teams inspect your roof during the assessment and objectively advise you whether prior renovation is worthwhile.
Are installations guaranteed?
Yes: 25 to 30 years performance warranty on modules, 10 years on inverters, and 5 years on installation and labour.
