A word from the founder

Choosing your solar installation should be as simple as booking a hotel online.

How it works

1
Your address

We identify your building in the federal register and measure your roof.
2
Your estimate

Output, annual savings and available subsidies, calculated on your roof rather than on an average.
3
Your advisor call

A neutral advisor calls you back and takes the analysis further with you.

From your roof to your offers

We do not install panels and we do not sell equipment. So the advisor who calls you back has nothing to sell you: they compare and they explain. At an installer, the person who calls you back is a salesperson.

1Studying your project

The layout on your roof

Panels are placed on your actual roof planes, pitch and orientation included. That is what gives the installable capacity, rather than an estimate per square metre.

The simulation, in several variants

With or without a battery, with or without a charging point. Each variant is calculated separately, production, self-consumption and return on investment.

The subsidies in your municipality

Federal, cantonal and communal, calculated on your roof and not on a Swiss average.

An advisor can build this simulation with you, over the phone, at any point.

You confirm, then we start

A neutral advisor goes through the study with you and confirms the project. Nothing reaches an installer without your agreement.

2The tender

A visit from an engineering office

An independent engineering office comes to you. Visual roof inspection by drone, and the injection capacity available on the grid. If the roof needs work, a roofer follows up.

One file, three installers

The same specification goes to up to three verified installers in the network. You chase no one.

The offers, scored and compared

Price, equipment, warranties, lead times. The same criteria for all three, so a comparison that holds.

The same advisor stays reachable throughout the tender.

How long does it take?

From the detailed simulation to the signature, count about one month.

1 Within 2 weeks
Technical visit

The technical office comes on site and completes your project's specification.
2 2 weeks
Offers compared

Your project goes out to installers, their offers are scored and compared.
3 Immediate
Choice and signature

You select your offer and sign electronically.
4 2 to 6 months
Installation

By your installer, depending on the project and the season.

Your project does not stop at installation

Your file, your offers and your documents stay in the SOLARSPLIT app, within reach.
Once the installation is running, the app tracks your production across all inverter brands and tells you how to make better use of what you produce.
The surplus you do not consume can be shared with your neighbours instead of simply being returned to the grid.

What you gain

More competitive offers

Three installers answer the same specification, knowing there are three of them. The project reaches them already qualified, roof measured and needs defined, so they have no prospecting to recover in your quote.

What is decided now stays with you for twenty-five years

Undersizing, wrong orientation, a subsidy missed: none of it can be fixed after installation. An independent engineering office checks on site before the first panel is ordered.

Three offers you can actually read

Capacity, equipment, warranties, yield over twenty-five years. All three are brought to the same criteria and scored, so you decide on comparable lines and not on an impression.

A community, not just a platform

Owners telling their story, installers making it happen, technical offices checking it. MicroSPLIT gives each of them the floor, filmed at our kick-offs across Romandie.

I had already received two quotes and had no idea what either one was worth. The advisor went through both with me, line by line, and I finally understood where the difference was.

OB Olivier B.

I thought my roof was too small. The estimate showed me the opposite in two minutes, without filling in a ten-page form.

YB Yann B. Cressier

What I appreciated is that nobody sold me anything, but nobody left me on my own either. Three offers compared, a straight opinion on each, and I made the choice.
