Free estimate · about 1 minute
Solar simulator free, in one minute
Find out in a minute how much a system where you are can produce, how much comes back to you each year and how long it takes to break even.

What it tells you
Three numbers, in one minute.
What it costs, VAT included
At average market prices, for the size you need.
What comes back to you every year
What you no longer pay on your bill, and what the GSE pays you for the energy you send to the grid.
How many years to break even
It isn’t the cost divided by the savings: the sum includes maintenance and the panels’ yield loss.
How much it produces
How much a solar system produces in Italy.
A well-oriented system produces 1,305 to 1,588 kWh a year for every kWp installed: Cagliari is the first of the 26 cities Sunnix measures, Trento the last. The simulator does the same sum at your address.

All 26 citiesWhere the numbers come from
The same sums for everyone.
- Production
- From PVGIS, the European Commission’s service, at the exact point of your address, with the orientation you choose or the best one for your area.
- Savings
- The energy you use is worth your price, or else the Italian average of €0.29 per kWh. The energy you send to the grid is paid by the GSE: €0.10 per kWh, €0.085 in the South.
- Payback
- Year by year, for twenty years: panels lose 0.5% of production every year, and maintenance is in the sum.
- What an estimate can’t see
- A nearby tree, the building next door, the state of the roof and of the wiring: that’s why the real price comes after the site visit.
Questions
Before you start.
Is the solar simulator free?
Yes, and without signing up: type the address and how much you use, and in a minute you see how much the system produces, what it costs and how many years it takes to pay back. We don’t ask for your email or your phone number.
How much does a 6 kW system produce?
7,828 to 9,525 kWh a year, depending on where it is: 7,828 in Trento, 9,525 in Cagliari, with the system oriented at its best. On a roof facing east or west a little less: the simulator counts it.
How accurate is the estimate?
Production comes from the sun measured by PVGIS at your point, averaged over nineteen years: from one year to the next it moves by a few percent. Nearby obstacles and the state of the roof stay out: only the site visit sees them.
What’s the difference from the configurator?
In the simulator you choose the power, or derive it from your consumption, and the orientation. In the configurator you draw the roof on the map, face by face. The simulator is the first number, the configurator the one closest to your roof.
Will someone call me after the estimate?
No. Sunnix doesn’t collect your contacts: under the estimate you find the companies in your area that work with Sunnix, and if you want a real quote you ask for it yourself, on their page.
