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.

The team explains
Eight short videos to understand your solar project before you ask for a quote.

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

A word from the founder
The electricity from your roof should benefit your neighbours before it goes to the grid for a few cents.
Wilfried Josset
Co-founder and CEO
The situation in figures
Surplus solar power goes to the grid for a few cents
Between your supplier's feed-in tariff and the full tariff your neighbours pay, there is room for a shared price that works for both sides.
- Feed-in tariff paid by the supplier for the surplus about 6 ct/kWh
- Shared price between neighbours about 20 ct/kWh
- Electricity bought from the grid, full tariff about 29 ct/kWh
Indicative example. The shared price is agreed between the participants of the group.
Two legal frameworks
Two ways to share, provided for by law
Depending on where the buildings sit on the grid, sharing takes one form or the other. SOLARSPLIT Community Connect handles both, at the same price.
CEL Since 2026
Local electricity community
- Participants in the same municipality
- The shared electricity travels over the public grid
- 40% off the grid usage tariff, 20% if a voltage transformation is needed
An RCPv can also join a CEL, as a single participant.
The process
From the map to the statement, step by step
SOLARSPLIT Community Connect takes care of the formalities, the decisions stay with you.
-
Your neighbours on the map
You choose which neighbouring buildings to share with. A single apartment building can also be enough.
-
Simulation and allocation key
Production, consumption and shared electricity are simulated. Participants agree together on the allocation key and the internal price.
-
Digital contracts
The contracts between participants are prepared for your group and signed online.
-
Setup and formalities
SOLARSPLIT registers the group and handles the formalities with the grid operator, under a power of attorney.
-
Statements and QR invoices
Smart meters measure every quarter of an hour. The statement, quarterly by default, allocates the shared electricity and each participant receives their QR invoice.
-
Reporting
Each participant follows the shared solar electricity and their own share in clear reporting.
For everyone
What each participant gains
Producer
Your solar surplus is sold to your neighbours at an agreed internal price, instead of going to the grid at the feed-in tariff alone.
Consumer or tenant
Solar electricity produced close by. For tenants, the price of the solar electricity recharged to them is capped, metering is not recharged and basic supply remains an option.
Owner or property manager
A free portfolio audit identifies the buildings where a group is possible.

Frequently asked questions
What we are asked most often
What is SOLARSPLIT Community Connect?
A service to share solar electricity between neighbours. It covers setting up the group, the formalities with the grid operator, the digital contracts and the statement of each participant.
RCPv or CEL, what is the difference?
An RCPv brings together buildings connected to the same point of the low-voltage grid, with no grid usage charge on the shared electricity. A CEL extends to a municipality and uses the public grid, with 40% off the grid usage tariff, or 20% if a voltage transformation is needed.
What are the conditions to form a group?
At least two participants and one solar installation. In an RCPv, production reaches at least 10% of the group's connection capacity. In a CEL, at least 5%, within the same municipality.
I have no solar panels, can I take part?
Yes. A group brings together consumers, producers and prosumers. It needs at least one solar installation, not necessarily on your roof.
At what price is the electricity exchanged?
At an internal price agreed between participants. In a CEL, it is free to set. In an RCPv, the price recharged to tenants is capped by law: the actual costs, or at most 80% of what they would have paid without the group.
How much does the service cost?
Setup is free. Then a flat fee of 15.- to 40.- per participant and year depending on group size, plus 2.0 ct per shared solar kWh, prices excl. VAT.
I am a tenant, what changes for me?
You keep the choice to stay on basic supply. The price of the solar electricity recharged to you is capped, and the group's metering is not recharged to you.
Does any equipment need to be installed?
No private meter. Metering relies on the grid's smart meters, every quarter of an hour.
What if solar electricity stayed in the neighbourhood?
An address is enough to start. We will look into what is possible for you.
