About us
Sunnix is the software born inside SoLink, which has designed and manufactured photovoltaic technology in Italy since 2013. It does one thing: it shows the real numbers of a system, before you buy it and after you switch it on.
In three numbers
26
cities with hand-calibrated PVGIS climatology: every value on the city pages is within 0.3% of PVGIS, month by month
5,000+
systems already estimated or configured by people who got here before you
01The problem
Whoever buys a solar system in Italy has the sellers' price lists and the quotes that land at home, and nothing in between: no place to see how much that roof yields, how much a system like theirs cost, and whether the promise on the bill came true.
After switch-on it is no better. The inverter portal says how much you produced, not whether that is right: a system yielding twenty per cent less than it should can do so for years without anyone noticing.
And sellers compete on a lead bought and resold to four other companies, with a number that arrives only after the site visit. Software paid for by those who sell the components will never print “this is not worth it for you”. Someone without that problem was needed.
02The mission
Three gestures, always the same, for the house, the warehouse and the field.
Estimate
The yield of your address, from the satellite and from PVGIS climatology calibrated city by city. Production, cost and payback years in a minute, no sign-up.
Compare
The price per kWp against what others really paid, in the observatory that collects records from people who already bought a system.
Verify
Every night, how much the system produced against how much it should have, with that day's weather. If the gap stays, the alert says the likely cause and what it costs.
It is the same measurement taken twice, and it forces us to be honest: an inflated estimate is contradicted by the meter six months later. The day every estimate has its check, we will be able to write on every system a sentence nobody writes today: promised this much, produced this much.
03What exists today
All free and without sign-up, except the two things that work with a company's name in front or on a system already running.
04How we work
They are why Sunnix is built this way and not otherwise.
Every number has a source and a date
Yield, incentives, energy price, CO₂ avoided: where each figure comes from is written on a page, with the date of the last check. If a rule is about to expire we notice first, with an automatic check.
Open to everyone, free, no sign-up
Homeowners, businesses, designers and installers use the same tool, with the same calculation engines. You pay only when Sunnix works with a company's name in front, or when it verifies a system already running.
We do not keep your customers' contacts
Requests born from a quote go to whoever should receive them and do not stay with us. The PDF is generated in your browser and never touches our servers. It is not a missing feature: it is a rule.
Nobody pays to appear
No manufacturer pays to be in the results, no installer buys a place on a list, no lead is resold. It is the only way an estimate and a price comparison stay credible.

Closing the circle
Every estimate with its check: promised this much, produced this much, on every system.
06Who is behind it
SoLink s.r.l. has designed and manufactured photovoltaic technology in Italy since 2013, and its founder has worked on solar since 2003. Sunnix was born there, in November 2023, as a tool for our own work: the estimates and quotes we send come out of here, and when something breaks we are the first to hit it.
It grew into a product of its own. Today thousands of people who have nothing to do with SoLink use it, and Sunnix is nobody's marketing department: it makes no calls, sells no hand-made studies, you try it on the site and buy it with a card. That the people who write it work in solar every day is not a conflict: it is why the numbers are the right ones.
There is no call centre. A doubt about a project, a strange case, a number that does not add up: we answer.
